Abstract (sommario):
SUMMARYA long-term trial with Leucaena leucocephala was initiated in 1982 to test the sustainability of Leucaena-based alley farming compared to a conventional cropping system without trees and with continuous cultivation of maize. It assessed the integration of short grazed fallows in rotation within Leucaena alleys and their effect on soil fertility and crop yields.The various treatments had no effect on soil pH during the four-year period of the trial. The organic carbon and total nitrogen contents of the soils under conventional cropping were lower by the end of the fourth year than those under alley cropping and alley grazing treatments, whereas soil phosphorus levels were lower in the alley cropping and grazing plots. Foliage dry matter production of Leucaena under alley cropping management ranged from 6.0 to 6.7 t ha−1 a−1 under continuous cropping and reached 8 t ha−1 when alley cropping was preceded by a grazed fallow. Crop yields were consistently higher with alley cropping than with conventional cropping. Alley cropping plots in rotation with two year grazed fallows gave significantly higher crop yields during cropping years than those under continuous cultivation.

Abstract (sommario):
SUMMARYThe profitabilities of three land use systems in the humid zone of southwest Nigeria are compared using a capital budgeting procedure combining on-station and on-farm experimental data. The systems are: non-alley farming with fallow; alley farming with fallow; and continuous alley farming. The results indicate that: continuous alley cropping is more profitable than non-alley or alley cropping with fallow; short fallowing in alley cropping reduces the rate of mining soil fertility and thus helps preserve future productivity; alley farming with small ruminants enhances the profitability of alley systems and increases their advantage over the non-alley system; and alley systems remain profitable even when terminal clearing costs are internalized in the current project cycle.

Abstract (sommario):
Agroforestry has a high potential to sustain agricultural production in the humid tropics. One specific type of agroforestry, alley cropping, has received much attention as a means of producing staple food crops within an agroforestry system. There is now substantial evidence that alley cropping maintains soil fertility above levels found in pure annual cropping systems. Nevertheless, competition between the trees and crops can significantly reduce yields by the crop. A model is presented of how the balance between the improved soil fertility in alley cropping and competition from the trees determines the final crop performance. Better understanding of the factors that determine crop yield will enable improved design and management of alley cropping systems, and may allow alley cropping to become a more reliable means of improving crop production.

Abstract (sommario):
Alley cropping allows the famer to effectively use available resources and yield more benefits. Choosing suitable associated crop and mitigating the competition between trees and crops are crucial for designing the alley cropping systems. We conducted a long-term experiment, including apple (Malus pumila)/peanut (Arachis hypogaea), apple/millet (Setaria italica) and apple/maize (Zea mays) alley cropping systems with conventional intercropping distance, and corresponding monocultures (Exp.1), and a short-term experiment with improved intercropping distance in the same three combinations (Exp.2) in the Loess Plateau, China. The results showed crop yields in three alley cropping systems were lower than the corresponding monocultures. Apple yields were significantly constrained by millet and maize in the alley cropping systems, but not sensitive to the presence of peanut. Land equivalent ratios (LERs) ranged from 0.44 to 0.89 before the tree bore fruit. The LERs were greater than 1.0 after the tree bore fruit, and the apple trees made a decisive contribution to the land use advantage. Net present values of three alley cropping systems were on average 60.1% higher than the corresponding monocultures across the alley cropping period. The maximum annual present value in the first–fifth, sixth and seventh–ninth years after the alley cropping establishment was observed in the apple/maize, apple/millet and apple/peanut system, respectively. These results highlight that choosing the optimal alley cropping management and suitable associated crops at different years after establishment may allow farmers to increase the land use efficiency and economic profitability.

Differences in Height, Number of Leaves, and Stem Diameter of Corn (Zea mays L.) in Alley Cropping and Intercropping of Agroforestry Systems at the Micro Watershed of Tukad Sumaga Village, Gerokgak District, Buleleng Regency. Degraded land as a result of land conversion has a very bad impact on the agro-ecosystem. Land conversion caused by the increasing needs of the population. The majority of the livelihoods of the people in Tukad Sumaga village are farmers. The availability of forage is very important to be maintained. Corn plants, in addition to their production in the form of corn, forage fodder on corn plants are very important for the availability of cattle feed. This research was conducted on 28 DAP maize (Zea mays L.) in alley cropping system and intercropping in the micro watershed of Tukad Sumaga Village. The results showed that the highest average plant height, leaf number, and corn stalk diameter were found in the alley cropping system namely 1.03 m, 7.31, and 1.59 cm. There was no significant difference between the height of corn plants in alley cropping and intercropping systems. There is a significant difference between the number of leaves and the diameter of the stems of maize in alley cropping and intercropping systems.

A field experiment was conducted to investigate the effect of pruned materials of two hedgerow species on wheat production and soil nutrient changes at different nitrogen levels in the research farm of the Bangabandhu Shiekh Mujibur Rahman Agricultural University (BSMARU) during November 2012 to March 2013. The design of the experiment was split plot, where two multipurpose tree species (MPTS) namely Gliricidia sepium and Leucaena leucocephala were arranged in main plots and five different doses of nitrogen (0, 25, 50, 75 and 100 % of recommended dose) with pruned materials were distributed to sub plots. Alley widths of both tree species were 6.0 meter. There were also control plots where full dose of recommended nitrogen was applied but no pruned material (PM) was incorporated. The soil chemical properties in the alleys consisting of G. sepium and L. leucocephala responded differently. Positive changes in the soil fertility in terms of soil pH, organic C, total N, available P, available S and exchangeable Ca, Mg, K and CEC of the top soil layer were observed in alley cropping system. Pruned materials application substantially reduced the nitrogen requirement for wheat production and 50 % Nitrogen fertilizer could be saved through pruned materials application. Among the tree species G. sepium seemed to be superior over L. leucocephala in building soil health.

Abstract (sommario):
Alley cropping or hedgerow intercropping is one of the many sub-systems of agroforestry technology. A 5 x 3 factorial experiment in a Randomized Complete Block Design (RCBD) with three replications was used to determine the effect of four alley woody species and three plantain cultivars on the yield of 60-day cowpea grain in the 2017 and 2018 farming seasons. The Alley species, plantain cultivars and Alley species x plantain cultivars treatment interactions showed no significant effects (p<0.05) on cowpea grain yield. Students t-test on the two farming seasons showed significant increase in yield of cowpea grain in 2018 than in 2017. Alley cropping technology could increase 60-day cowpea grain yield due to improved soil fertility in the system.

Abstract (sommario):
Alley cropping is a specific agroforestry system, which is regarded as sustainable land use management, that could play a crucial role in climate change adaptation and mitigation. Despite its appealing attributes, farmers’ up-take of the system is slow in temperate regions. This study aims to contribute to scaling-up agroforestry through a case study in Hungary and to help to design productive alley cropping systems. We investigated which tree planting pattern of black locust (Robinia pseudoacacia L.) results in the most productive alley cropping system when intercropped with triticale (x Triticosecale W.) by statistically analysing the yields of the intercrop and of the trees in nine different layouts and by calculating land equivalent ratios (LER). There was significant difference between the treatments both in triticale and black locust yields. The more trees planted on a hectare, the higher the volume of the stand, and the less yield of triticale was observed, although the latter correlation was weak and in some cases the triticale was more productive between the trees compared with sole crop control. Eight out of nine treatments had favourable LER (0.94–1.35) when the trees were five years old. Black locust and triticale seem to be a good combination for productive alley cropping systems.

Abstract (sommario):
A sustainable management of soils with low natural fertility on family farms in the humid tropics is a great challenge and overcoming it would be an enormous benefit for the environment and the farmers. The objective of this study was to assess the environmental and agronomic benefits of alley cropping, based on the evaluation of C sequestration, soil quality indicators, and corn yields. Combinations of four legumes were used in alley cropping systems in the following treatments: Clitoria fairchildiana + Cajanus cajan; Acacia mangium + Cajanus cajan; Leucaena leucocephala + Cajanus cajan; Clitoria fairchildiana + Leucaena leucocephala; Leucaena leucocephala + Acacia mangium and a control. Corn was used as a cash crop. The C content was determined in the different compartments of soil organic matter, CEC, available P, base saturation, percentage of water saturation, the period of the root hospitality factor below the critical level and corn yield. It was concluded that alley cropping could substitute the slash and burn system in the humid tropics. The main environmental benefit of alley cropping is the maintenance of a dynamic equilibrium between C input and output that could sustain up to 10 Mg ha-1 of C in the litter layer, decreasing atmospheric CO2 levels. Alley cropping is also beneficial from the agricultural point of view, because it increases base saturation and decreases physical resistance to root penetration in the soil layer 0 - 10 cm, which ensures the increase and sustainability of corn yield.

Abstract (sommario):
Population pressure has diminished the role of the traditional bush fallow system in restoring the fertility of depleted soils following several years of cultivation in the derived savanna of southwest Nigeria. The search for alternative fallow systems led to the development of alley cropping using Leucaena leucocephala and cover cropping using Pueraria phaseoloides. These soil-conserving systems also embody the principles of sustainability by ensuring stable crop yields in spite of an increase in land-use intensity. Simulating smallholder farm conditions and based on a split-plot experiment with the three fallow systems as the main plots and four different land-use intensities (LUI) as the subplots, simple direct observation and record keeping were used to collect data on labour use in all farm operations including fuelwood cutting and stacking in alley cropping systems with fallow phases. Data collection covered a period of four years (1993–96), corresponding to one out of the three phases (or complete cycles) of the trial. Partial budget analysis was used to estimate profitability of cassava (Manihot utilissima)–maize (Zea mays) under each LUI. Results based on crop production indicate that each of the cassava-maize enterprises was profitable but the level of profit varied from 10 819 to 50 289 Naira ha−1. Production under cover cropping has a net benefit advantage of 4–25% (over that under bush fallow) and 25–60% (over alley cropping). Profitability increased as the LUI decreased, depicting the overall importance of fallow periods on soil fertility restoration. Results based on crop production plus fuelwood operations indicate that production with cover cropping has a net benefit advantage over that of both bush fallow and alley cropping under both zero-fallow and one-year fallow LUIs. However, results from two- and three-year fallows indicate that fuelwood yield generated sufficient revenue to put alley cropping at a net benefit advantage of 29–42% over bush fallow and 26–37% over cover cropping. From these results, cover cropping is recommended, especially to farmers in areas where, although land shortage is a problem, fuelwood and the other sources of domestic energy are still cheap and easily accessible. However, in areas with abundant land and where farmers can still wait for fallow periods of at least two years, alley cropping is recommended since, in addition to soil fertility improvement, substantial revenue is obtained. However, considerations of yield variability, labour scarcity, as well as risk-aversion behaviour among farmers may alter their technology choice.

Abstract (sommario):
Efficient use of irrigation and nutrients are becoming increasingly important in commercial orchards in the Hawkesbury area. Proper irrigation scheduling practices can help in the better use of irrigation water and reduce environmental impacts. Field experiments were conducted during February 1999 to June 2000 to understand soil-water use, and to evaluate farmer’s irrigation practice under an alley cropping system consisting of turf and stone fruits. The study was carried out at Atlas Farm, 3.5 km from the University of Western Sydney, Hawkesbury campus. The experimental site is a floodplain of the Hawkesbury River. The river flows within 1 km of the farm boundaries. The study was conducted under the farmer’s existing irrigation water and nutrient management practices. The main aims of the thesis were to study the movement and redistribution of soil-water and soil-moisture dynamics in the turf and stone fruit alley cropping system and to understand deep percolation losses and nitrogen leaching using the water balance approach. The study indicated that drainage occurred mainly after heavy rainfall and when there was rainfall for a few consecutive days. Thus irrigation application should be delayed if there is a likelihood of rain in a few consecutive days to prevent loss of water due to deep drainage. Furthermore, the study showed irrigation scheduling was essential to reduce nitrate leaching in the field; that irrigation depths should be varied according to the stage of crop growth, and the proper timing of irrigation application could help reduce deep percolation and runoff losses.

Abstract (sommario):
The components of soil CO2 efflux are affected by many soil properties including temperature, moisture, microbial abundance and activity, and other soil physical and chemical properties. Changes in these factors can result in high spatial and temporal variability of total soil CO2 efflux. Low molecular weight organic acids (LMWOAs), dissolved organic carbon (DOC) and dissolved organic nitrogen (DON), microbial biomass and activity were measured to evaluate the impact of intercropping switchgrass (Panicum virgatum L.) in a loblolly pine (Pinus taeda L.) plantation. Surface soil samples (0-15 cm) were collected on the bed (PSG-B), interbed (PSG-I) and edge (PSG-E) of pine-switchgrass intercropped treatments, as well as pine only (P-B) and switchgrass only (SG-I) treatments. Differences in most soil properties and processes of intercropped treatments were sporadic and most did not show clear trends. However, significant correlations between DOC, soil temperature, oxalic and acetic acids and soil CO2 efflux were present. In an multiple regression model these factors explained 57% of the variance in total soil CO2 efflux. Therefore we think that LMWOAs, as a labile component of DOC, are influencing total CO2 efflux because they are being consumed by microbial community, increasing heterotrophic respiration and as a result overall total CO2 efflux. The amount and distribution of labile C controls microbial community dynamics, heterotrophic respiration as well as the stabilization of soil C.

Sugarcane plantations are increasing in Brazil motivated by the demand of the sugar industry and the energetic sector. Sugarcane monocultures simplify the landscape and disconnect natural ecosystems. The inclusion of native trees in the canebrake, changing the matrices into an alley cropping system, is a new proposal that consider the environment beyond production. In order to assess the environmental effects in agroforestry was raised sugarcane productivity and development of trees in three crops (2009/10, 2010/11 and 2011/12), as well as the timber volume and carbon sequestration produced by the system at the end of the year 2012 and a bird survey during 2011 and 2012 in an experimental area of 1,957 hectares. Was found orderly development of tree species. Schizolobium parahyba present a significant mortality, but had the largest wood production thus coming to the same conclusion in relation to carbon sequestration, which are 3 times those of the Handroanthus spp. and 2 times the Cedrela fissilis. There was no change in the sugarcane productivity related to the distance line planting was the alley, with only a drop productivity in the range of 58 m cultivation. Birds are important bioindicators; trees contributed to the increased diversity of birds, being Schizolobium parahyba the arboreal species of most relevant importance. The spacing between alleys with the greatest diversity of birds was to 29 m. It is concluded that it is technically possible deployment agroecosystem proposed, without agronomic production damage of cane sugar; the 2 smaller bands cultivation (29 m and 43.5 m) are the most suitable; among tree species Schizolobium parahyba was the one with the best results in the short term, since the issue of mortality could be remedied with proper management or replanting.
O plantio de cana-de-açúcar está em franca expansão no Brasil motivado pela demanda do setor sucroenergético. Os canaviais em matrizes monoculturais simplificam a paisagem e desconectam ecossistemas naturais. A inserção de aleias com árvores nativas em canavial é uma nova proposta que contempla o ambiente além da produção. Com o objetivo de avaliar os efeitos ambientais e a produtividade agrossilvicultural nesse sistema agroflorestal, foram levantados em uma área experimental de 1,957 hectares, o rendimento da cana-de-açúcar e o desenvolvimento das árvores constituintes das aleias em 3 safras (2009/10, 2010/11 e 2011/12); bem como o volume de madeira produzido e a fixação de carbono pelo sistema ao final do ano de 2012; e a dinâmica da avifauna durante os anos de 2011 e 2012. Constatou-se um desenvolvimento regular das espécies arbóreas, observando grande taxa de mortalidade do guapuruvu (60%). Foi possível constatar a maior produção de madeira pelo guapuruvu, consequentemente chegando aos mesmos resultados em relação à fixação de carbono, sendo estes 3 vezes superiores aos do ipê e 2 vezes ao cedro. A produtividade da cana não esteve relacionada com a distância entre a linha de plantio e a aleia, apresentando queda apenas na faixa de cultivo de 58 m. A avifauna foi considerada um bioindicador consistente; o guapuruvu foi a espécie florestal com maior importância para o aumento da diversidade de aves e o espaçamento entre aleias com a maior riqueza foi o de 29 m. Conclui-se que é tecnicamente possível a implantação do agrossistema proposto, sem prejuízo agronômico da produção da cana-de-açúcar, sendo as 2 menores faixas de cultivo (29 e 43,5 m) as mais propícias e o guapuruvu a espécie arbórea com melhores resultados em curto prazo, desde que a questão da mortalidade seja sanada com replantio ou manejo adequado.
