AC Hill oat (Avena sativa L.) is a spring-type, daylength-sensitive, naked-seeded cultivar suitable for the feed and food industries in eastern Canada. It outperformed the check cultivar Tibor in yield, kernel size, hectolitre weight, and percentage of covered seeds in threshed grain. It is resistant to crown rust (Puccinia coronata Cd. f.sp. avenae Eriks. and E. Henn.) race CR13 but is equal to Tibor in loose smut (Ustilago avenae (Pers.) Rostr.) resistance, plant height and susceptibility to septoria (Septoria avenae Frank f.sp. avenae) blotch and barley yellow dwarf virus (BYDV). It is more susceptible to lodging and later in heading and maturity than Tibor.Key words: Avena sativa L., rust and smut resistance, cultivar description, naked oat

Studies were conducted on the status of insect-pests and natural enemies of direct seeded rice (DSR) in comparison with puddled transplanted rice (PTR) during rabi and kharif in 2013-14. The rice leaf folder and yellow stem required both the seasons. Maximum leaf folder Cnaphalocrocis medinalis (Guenee) (13.03%) damage and yellow stem borer damage (13.49%) of white ears was recorded during last week of October and second week of November in DSR under unprotected situation respectively. While sucking pests population mainly green leafhopper incidence was comparatively high in PTR (3.29 and 4.92/hill) also plant hoppers incidence (BPH and WBPH) (28.90 and 18.44 adults/hill) under unprotected situation during two seasons respectively. Population of predators at both the season remained high throughout the study period in PTR than the DSR except

This project investigates the effects of leaf side, leaf position, individual plant, and hill (or plant group) on phytolith assemblages from Zea mays L. cultivar Mandan Yellow Flour. Thirty-two samples were examined, and 200 phytoliths were classified from each sample. Statistical analysis indicates that leaf side is significant at the 0.05 level above random counting variation; leaf position, individual plant, and hill are not generally significant beyond the effect of leaf side. Analysis of a single sample, either a half or entire leaf, is not sufficient for compilation of representative phytolith assemblages from a plant population. Phytolith reference collections should not be based on single samples of each species. Multiple samples from a population need to be analyzed to obtain information on assemblage variation within the population. The variation of corn phytolith assemblages in this study overlaps those of many Panicoid grasses, indicating that additional morphological characters need to be identified to distinguish corn from wild grasses in the Great Plains. Key words: phytoliths, corn, frequencies, variation.

Two field experiments were carried out at the Experimental Farm of Gemmeiza Agriculture Research Station, Agricultural Research Center (ARC), Egypt after 2018 and 2019 summer growing seasons to determine the effect of intercropping pattern of yellow maize hybrid (single cross 168: “SC 168”) with watermelon pulp at three plant distributions (20 cm between hills and one plant/hill, 40 cm between hills and two plants/hill and 60 cm between hills and three plants/hill) and different levels of nitrogen fertilizer (25, 50, 75 and 100% of the recommended dose “120 kg N fad-1”) as well as their interactions on maize and watermelon pulp growth, yield and its attributes as well as competitive relationships and yield advantages. The experiments were carried out in split-plot design with four replicates. The main-plots were assigned to plant distributions of maize, the sub-plots were allocated to levels of nitrogen fertilizer for maize. The obtained results showed that planting maize plants on one side of terraces of 140 cm width with 20 cm between hills and leaving one plant/hill and planting watermelon pulp on the other side of the terraces produced the highest values of plant height, ear height, number of kernels row-1, 100-kernel weight and grain yield fad-1, at the same time the lowest values of ear leaf area, ear length, ear diameter and number of rows ear-1 of maize as well as the lowest values of growth, yield and its attributes of watermelon pulp during the both seasons. Mineral fertilizing maize plants with 75% of the recommended dose (90 kg N/fad) and watermelon pulp with the recommended dose produced the highest values of all studied growth characters, yield and its attributes of maize and watermelon pulp in both seasons. The highest values of land equivalent ratio (LER), relative crowding coefficient (RCC), area time equivalent ratio (ATER), land equivalent coefficient (LEC), aggressivity index (AI), monetary advantage index (MAI), actual yield (L.E.) of watermelon, Total income (L.E.) and economic return (L.E.) were obtained from planting maize plants on one side of terraces of 140 cm width with 60 cm between hills and leaving three plants/hill and planting watermelon pulp on the other side of the terraces besides fertilizing maize plants with 75% of the recommended dose (90 kg N/fad) and watermelon pulp with the recommended dose in both seasons. It can be recommended that planting maize on 60 cm between hills and leaving three plants/hill and planting watermelon pulp on the other side of the terraces besides fertilizing maize plants with 90 kg N/fad and watermelon pulp with the recommended dose to obtain the maximum values growth, yield and its attributes of watermelon pulp and competitive relationships and yield advantages of both crops under the climates conditions of Middle Delta, Egypt.

Aerial sowing is the only option for introducing improved pasture species into much of the non-arable, acid soil rangelands in central New South Wales. However, low germination of seeds in serradella pods is a major problem causing poor establishment. Sowing different combinations of pod and seed was investigated as a means of improving germination and subsequent persistence in an experiment between 1993 and 1997. Results indicated that a pod:seed mixture of 75:25 was the most suitable ratio for establishing yellow serradella (Ornithopus compressus) when broadcast into native grassland on hardsetting, non-arable, acidic hill country. Nodulation failure observed at this cold tablelands site confirmed the need for a more winter-active inoculant for yellow serradella.

Trifoliate orange seedlings are used as rootstock for citrus crops due to cold hardiness and phytopthora disease tolerance. Nursery owners usually prepare raised bed in open field to sow seeds of trifoliate. The trifoliate seed production in government farms are very low compared to its demand due to limited number of fruiting trees. Further the germination percent in open nurseries are very low. Hence, production of grafted sapling is very much affected by unavailability of rootstock. Therefore, a study was carried out in National Citrus Research Program, Dhankuta to increase germination rate of trifoliate orange in the year 2016 and 2017. Trifoliate seeds were extracted from three stages of fruits (green mature, half yellow and full yellow) and sown at three dates (September 1st week, September 3rd week and October 1st week) at three raised bed (open field, 50-cm low plastic tunnel with or without sides open). The data on percentage seed germination was taken at 35, 50, 65, 90 and 210 days after seed sowing. The fruit maturity had no effect on germination percentage irrespective of sowing date and method of beds used. The date of sowing resulted significantly higher germination at earlier days but there was non-significant effect during final germination count. Plastic tunnel with open sides resulted 80% germination compared to 46% in tunnel side closed nursery. Hence, low plastic tunnel raised bed having open sides is the best option to raise trifoliate seed sown during 1st week of September to 1st week of October in agro-climatic conditions like Dhankuta.

Although lentil has a long history of cultivation, cultivars rely on a narrow genetic base, indicating room for broadening the diversity. Two field experiments were conducted at Bardiya, Nepal, during winter 2016 and 2017, with 324 diverse lentil genotypes obtained from genebanks and breeding programs around the world. Phenological traits related to adaptation, particularly days to flower, were assessed. A photothermal model was used to predict days to flower in new environments to identify genotypes that may be suitable for additional growing regions in Nepal, allowing for the expansion of the production area. Many putatively adapted genotypes were identified for terai, mid-hill, and high-hill growing regions. The list includes large-seeded or yellow cotyledon lines, representing new market classes of lentils for Nepal.

The present study presents an overview on floral diversity and identifies Non-timber Forest Products (NTFP) that can be used as Natural Dye sources in textile sector. This was a descriptive study; Historical, as well as current data was collected through surveys and interviews. Individual and focus group interviews with tribal members were conducted to gather information regarding details of forest proximity. This collective study indicates that the Aravalli hill ranges constitute the most dominant hilly area of Rajasthan. Most of the forests are over the hilly areas i.e. in Udaipur, Rajasamand, Kota, Baran Sawai Madhopur, Chittorgarh, Sirohi, Bundi, Alwar, Jhalawar and Banswara districts, which make up for about 50 per cent of the forests of the state. Khakara, semal, rohida, gadha palash, mokha, marod phalli, davai, van gulab etc. are identified as red chroma, amaltash, awla, gundhi, babool etc.are identified as yellow and related chroma. Forests are major components of the earth’s natural resources and they are increasingly critical to the welfare of the economy, environment, and population. Gum products, starch products, antimicrobial resources, paper industry products may be collected from hilly forest areas and can be easily adopted at cottage level for gainful employment of tribal women.

Soya bean (Glycine max) meal is an important component of animal feed and oil seed rape and palm kernel cake and meal are typically used in commercial concentrate diets for sheep in the UK.. Lupins (Lupinus; Leguminosae) as a high protein, high energy, nitrogen-fixing grain legume, have potential as a home-grown livestock feed in the UK (Wilkins and Jones, 2000). Research has been conducted on the effects of narrow-leafed lupins (Lupinus angustifolius) (Hill, 2005) but there have been few studies on the effects of yellow lupins (Lupinus luteus) when fed to sheep. This study investigated the effects of incorporating either yellow lupins, narrow-leaf lupins or soya bean meal into the concentrate diets of finishing lambs on lamb productivity and carcass characteristics when compared to a commercial UK lamb finisher diet.

This diploma thesis gives a proposal for a new Moravian wine center in the city center of Brno. Wine center is situated on the street Hlinka, where grapevines were planted in the Middle Ages. Demarcated land is narrow and elongated sloping towards to the south and connects the Yellow hills and the Brno Exhibition Centre. The main idea of this thesis is connect these two significant locations and offer the visitor a free passage along the entire length of the complex. Also main building Moravian Wine Centre reflects this fact and it expands the space of the street stalls and forms it into overgrown "arcade". The house is opened into this space - with glazed facade of the first two floors or with transmission into the rear wing. The main building consist of the cellar, where it is located wellness, winehouse, rentable wine boxes and tasting room connected with wine production. The rest of floors are designed for wine gallery, information center, reception, shop, restaurant, conference center and hotel. There is a café with roof terrace in the last floor. It offers a magnificent view into cityscape of Brno, Brno Exhibition Centre and the Yellow slope of the hill. There is designed a pond for relaxation in the courtyard. Nearby is situated Wine Institute building with facilities for making wine. In the second half of the land are located three blocks of luxury apartments in the middle of a vineyard. A leading construction is the most striking feature of the facade that reminds bougainvillea vines with vaulted arches wine cellars and attracts at first sight.

Only since the last two decades of the twentieth century have professional geologists been working specifically at Miletus, investigating the shiny white limestone on top at KalabakHill; the limestone of Theater Hill and Humei Hill; and the limestone of Zeytin Hill (at the west of the hill called Degirmen, west of Kalabak), with sandstone and tuff to the east. The stratigraphy at Miletus is as follows, beginning with the topmost modern layer: . . . Iron deposits in mountains east of Miletus and both iron and brown coal at Mt. Mykale (today Samsun Dag) north of the Meander River valley. Volcanic tuff. Soluble limestone: 200 m of Yatagan or Balat strata of marble with tufa, sand, and gravel from which springs emerge. Early Pliocene limestone, shiny white limestone cap 60–100 m thick, karstified but with few on-site springs, forming ridges, hills, and a thick layer of scree. Miocene marls, sandstones, conglomerates, and clays with springs. Pink-yellow sandstone, sometimes with tuff, around sides of hills. Older clayey limestone deposited in a lake environment. Former large bay, now a swampy river plain with rich alluvial soil. . . . Prof. B. Schröder and his team have done geological research in the area (1990–94) and published their findings swiftly, which I acknowledge with gratitude. Suspected faults run north and south of Kalabak Hill (recognized in C. Schneider 1997). The town of Akköy to the south, where the German archaeological house is located well above the mosquitoes of the archaeological site in the swampy plain, sits on limestone that forms a peninsular ridge, surrounded on three sides by sandstone with tuff. The west coast of Asia Minor is subject to strong relief, steep gradients, and high precipitation; the high amount of energy available allows rapid change in topography (Gage 1978: 621). In Ionia, on average, the sea has risen or the land has sunk 1.75 m since antiquity (Bintliff 1977: 24; 1992). The Greek cities of Asia Minor were without exception built on or next to karst terrain (V. Klemes, 1988, personal communication when he was president of the International Association for Karst Hydrology).

When travelers today go from downtown Wenzhou to Rui’an, the first things they see along the newly built Yong-Tai-Wen highway are stretches of paddy fields; small, winding rivers, and lush, low hills in the distance. Next to appear are traditional Chinese buildings dotting hillsides and fields, too bright to miss. Some of them have yellow-painted walls and grey tile roofs. Others are adorned with colorful motifs, statuettes of various kinds displayed in cornices, and occasionally flags of various colors on the rooftops. The yellow buildings are easily recognizable as Buddhist temples, while the colorful buildings are temples for territorial religion. Most of them look fairly new. Careful observers will also notice many newly built Christian churches in a variety of styles, some recognizable, others harder to identify, dispersed in the plains along the highway. These are views the northern soldiers would not have seen on their way to Rui’an in the summer of 1949, when the Communist Party’s Eastern China Field Army came south to Wenzhou to take over the region from local Communist guerrillas....

Soul Flower Farm sits on the edge of a series of rolling hills in California’s East Bay, in the city of El Sobrante located about ten miles from Berkeley. Goats graze on the hillside, and one can hear chickens clucking in their coop. On a wooden shed nearby is a painting of a giant golden sunflower with a vibrant magenta center, across from which the farm announces its name to visitors. On a crisp summer day in 2015, the mural almost sparkles, its vivid colors accentuating the green of the trees around it, as well as the pale, brittle yellow of the grass beneath it, the result of a five-year drought in California, which the state eventually declared over in 2017. Soul Flower Farm’s website describes it as “a small urban farm … striving to incorporate biodynamic farming methods and permaculture design to be self-sustaining.” Under a photograph of its proprietors, Maya Blow and her husband, Yasir Cross, the description continues: “Raising goats, chickens, ducks, bees, and boys, homeschooling, sustainable building, and practicing holistic medicine keeps us busy.”...

It is an uncommon gift to have a mountain to yourself. Pulling up to the trailhead for the Bell Mountain Wilderness Area, I saw no other vehicles parked there and began to hope for as much. I noticed that the dirt road into the area hadn’t been graded recently. Another good sign was my having to wipe spider webs from my face every hundred yards or so as I hit the trail. Obviously no one had been there for a while. But the real treat was reaching the top of the mountain and finding nothing. A favorite campsite lay empty, nestled in the rocks just above the treetops. From there you can look out onto thousands of acres of oak- and hickory-covered hills to the east. Not a road or a building in sight, nothing but trees. Bell Mountain is one of eight protected wilderness areas in Missouri. It is named after a family that once lived and farmed along its 1,700-foot ridge. I’d gotten a late start that day and the sun was going down by the time I set up camp. But sunlight on a late April afternoon, filtered through the yellow-green growth of new leaves, can be stunning. I sat on a rock ledge, cutting up potatoes, onions, and carrots for mulligan stew, watching shadows creep up the hills across the hollow. Putting the vegetables in a pot, I added fresh basil and rosemary, topped it off with ground beef, and washed it down with a shot of Grand Marnier as night came on. I delight in the solitude of these trips, but I’m not always sworn to a monastic austerity. Bell Mountain is a good place for the study and practice of solitude. I’ve sat there for hours with only the dog beside me, watching red-tailed hawks and turkey vultures soar on thermals rising from the forest below. Now and then you’ll see a lone eagle high overhead, though generally they nest closer to the river. Bald eagles are common in Missouri, especially in winter.

June, when the snows come hurrying from the hills and the bridges often go, in the words of Emily Dickinson. In the beaver meadow, the snows are indeed hurrying from the surrounding hills. Every one of the 32 square miles of terrain upslope from the beaver meadow received many inches of snow over the course of the winter. Some of the snow sublimated back into the atmosphere. Some melted and infiltrated into the soil and fractured bedrock, recharging the groundwater that moves slowly downslope and into the meadow. A lot of the snow sat on the slopes, compacted by the weight of overlying snow into a dense, water-rich mass that now melts rapidly and hurries down to the valley bottoms. North St. Vrain Creek overflows into the beaver meadow, the water spilling over the banks and into the willow thickets in a rush. I can hear the roar of water in the main channel well before I can see it through the partially emerged leaves of the willows. Overhead is the cloudless sky of a summer morning. A bit of snow lingers at the top of the moraines. Grass nearly to my knees hides the treacherous footing of this quivering world that is terra non-firma. I am surrounded by the new growth of early summer, yet the rich scents of decay rise every time I sink into the muck. I walk with care, staggering occasionally, in this patchy, complex world that the beavers have created. I abruptly sink to mid-thigh in a muck-bottomed hole, releasing the scent of rotten eggs, but less than a yard away a small pocket of upland plants is establishing a roothold in a drier patch. A seedling spruce rises above ground junipers shedding yellow pollen dust and the meticulously sorted, tiny pebbles of a harvester ant mound. I extract my leg with difficulty and continue walking. As I walk around the margin of another small pond, the water shakes. Sometimes the bottom is firm in these little ponds, sometimes it’s mucky—I can’t tell simply by looking through the water.

The Lake Wales Ridge stretches out along Florida’s central spine, pointing southward like an arrow toward Lake Okeechobee and the Everglades beyond. The “river of grass,” as the Everglades are known, attracts visitors from around the world to experience this unique ecosystem and view its immense wildlife concentrations. Compared to its famous neighbor to the south, the Lake Wales Ridge is virtually unknown to the public. From a biological perspective, though, these low, scrub-covered sand hills are of perhaps greater interest than the immense wetlands of the Everglades, because the ancient sand dunes that form this ridge are home to some of the most distinctive and highly localized species in the world. Yet most of the scrub vegetation that supports these species has been destroyed, replaced by agriculture and housing developments: Only about 15% of this unique habitat remains (Menges 1997). Among the rarest of the ridge’s inhabitants is the Lake Placid scrub mint (Dicerandra frutescens), known from just a handful of localities. This mint produces chemicals that have a powerful deterrent effect on insects and that could provide the key to developing new forms of insect repellents useful to people (Eisner et al. 1990). Although these chemicals protect the mint from being devoured by insects, the plant has little protection against the development pressures that threaten it. Another resident of the ridge is the yellow scrub balm (Dicerandra christmanii), a closely related mint that has an even more restricted distribution. Both of these plants are regarded as critically imperiled (GI), and both are listed by the federal government as endangered. Sharing the Lake Wales Ridge with these rare plants is the Florida scrub jay (Aphelocoma coerulescens), a bird that is mostly restricted to the scrub along Florida’s central ridge but occurs in scattered locations along Florida’s Gulf and Atlantic Coasts as well. Florida scrub jays have the unusual characteristic of living in family groups. To survive in a particular location, these birds need a large enough area of suitable habitat to support a number of these family groupings. This species is regarded as vulnerable (G3) and listed as threatened under the Endangered Species Act.

The process of scientific discovery is something like a walk near Freswick Castle. I assume you’ve never been there. (Neither have I, but a friend has.) Freswick Castle stands at the end of Scotland’s northeast end, at the mouth of the Burn of Freswick in the district of Caithness. As of this writing, it is unlisted in Google Maps, and I had to manually scan the coast to find it. Outside the castle is a simple, unlabeled structure that doubles as a biochemical parable. The castle itself is narrow and three stories tall, with orange shingles and gray stone, set on an arc of narrow beach between hills to the north and cliffs to the south. The building is approximately the cruciform shape of a shrunken cathedral, with the rightward wing moved to the top of the structure so it resembles a lowercase f. If you wander the grounds near Freswick Castle, you will discover a stone wall in the wind-blown waves of yellow- green grass, worn but still standing firm like Hadrian’s Wall. From above, it is a period preceding the castle’s f. Let’s approach this as a scientist, with measurement. From the castle side, this structure resembles the circular stump of a roofless tower, eight feet tall and twice that wide. The stones are ancient sand, compacted and weathered, stained different shades of red from iron deposited millions of years ago, but the mortar is new. But inspection is not enough—we should go in. Walk around to the other side, and an opening appears, as shown in Figure 2.1. The structure is not a closed circle, but it is a spiral wall open to the sea, and to you. Inside, a small stone bench invites you to sit. A window slit next to the bench is an eye to the outside. Surrounded by a jigsaw of rocks, you can hear the echo of waves all around and watch the blue-gray sky above. If the spiral’s opening is a mouth, then you are Jonah in the whale. You are both inside and outside at once.
