Abstract:
The aim of this study was to determine the effect of the interaction between the tillage system and weed control on the growth and yield of maize (Zea mays saccharata Sturt.) Paragon variety. The experiment was carried out in Cibalong Village, Ciheulang Village, Ciparay District, Bandung Regency. The time of the experiment was carried out from September to December 2020. The study used an experimental method, with a Randomized Designated Separate Group with a factorial pattern consisting of 2 treatment factors, namely the tillage system and the weed control system. The tillage system consists of TOT (No Tillage), OTMin (Minimum Tillage), OTMax (Maximum Tillage), while the weed control system factors consist of g1 (No Weed Control) g2 (Physical Mechanical Weed Control) g3 (Physical Mechanical Weed Control) Weed Chemically). The results showed that there was no interaction effect between tillage system and weed control on all observed parameters.

Abstract:
Abstract Sweet corn production in Indonesia from is volatile and unstable. Unoptimal production of sweet corn in North Sumatra is caused by land conditions, plant populations, pest and disease and level of soil fertility. Effective and efficient soil tillage, crop spacing and number of seeds will affect the physical properties of the soil and plant productivity. This study aims to observe the best planting and tillage methods for maize. This study used a split plot design which is repeated three times with two factors, i.e. 3 levels of number of seeds per planting hole and 3 levels of soil tillage. The results showed that the treatment of tillage and the number of seeds per planting hole give significant effect on the variables of plant height, stem diameter, and total production. The interaction of these two factors showed an influence on the parameters of sweet corn plant height. The treatment of 2 seed per planting hole and 1 time of soil tillage show the best productivity compared to other treatments.

Abstract:
AbstractWeed management is one of the primary challenges for producers transitioning from conventional to organic agriculture. Tillage and the use of cover crops are two weed control tactics available to farmers transitioning to organic management, but little is known about their interactive effects on soil quality during the transition period. We investigated the response of soils to tillage and initial cover crop during the 3-year transition to organic in a cover crop–soybean (Glycine max)–maize (Zea mays) rotation in the Mid-Atlantic region of the USA. The tillage treatment contrasted full, inversion tillage with moldboard plowing (FT) versus reduced tillage with chisel plowing (RT). The cover crop treatment contrasted annual versus mostly perennial species during the first year of the rotation. The experiment was initiated twice (Start 1 and Start 2), in consecutive years in adjacent fields. By the end of the experiment, labile carbon, electrical conductivity, pH and soil moisture were all greater under RT than under FT in both starts. Soil organic matter and several other soil attributes were greater under RT than under FT in Start 1, but not in Start 2, perhaps owing to differences between starts in initial field conditions and realized weather. Soil attributes did not differ between the two cover crop treatments. Combining our soils results with agronomic and economic analyses on these plots suggests that using RT during the organic transition can increase soil quality without compromising yield and profitability.

Abstract:
Three-year field trials were conducted to compare the effect of three tillage systems: strip-tillage (ST), strip-tillage after mouldboard ploughing (STmp) and conventional tillage (CT) on growth and yield of winter oilseed rape at the experimental station in Červený Újezd, Czech Republic. Compared to CT, the growth of roots and aboveground biomass was slower (significantly thinner root necks, shorter roots and leaves) under ST at the beginning of vegetation (BBCH 14–18). Plants under ST still had significantly thinner root necks, and a lower number of leaves than plants from CT before winter (BBCH 21) but the differences were no longer statistically significant in spring (BBCH 30). Despite a slower start, the ST variant with an average yield of 5.47 t/ha significantly exceeded the CT variant with the yield being 5.06 t/ha. Conversely, plants grown under STmp had significantly longer leaves than those under CT in BBCH 14–18 and with the highest values of all parameters, tended to faster growth of biomass, although the other differences were not statistically significant. No differences were observed between STmp and CT in BBCH 21 and 30. The STmp variant achieved the highest yield 5.53 t/ha, and significantly exceeded the CT variant.

Abstract:
Artikeln bidrar till fördjupad förståelse av lokala förutsättningar för skolutveckling genom kollektivt lärande i arbetslag. En longitudinell fallstudie genomfördes av skolutvecklingsprocesserna i fem arbetslag på olika skolor som deltog i ett identiskt, externt utformat, utvecklingsprojekt. Projektet innebar en handledd lärandeprocess där lärarna förväntades utveckla gemensam kunskap och kompetens genom kollektiv reflektion, baserad på synliggjord praktik i form av kollektivt planerade och genomförda elevinterventioner. Interventionerna bestod i kartläggning av skolsvårigheter, filmade samarbetsbaserade lärar-elevsamtal och uppföljningar av dessa, med anpassningar i undervisning och elevarbete. Utfallet av projektet, såsom skattat av lärarna efter två år, varierade stort mellan skolorna. Variationen i utfall, trots att arbetslagen deltagit på jämförbara premisser och med likvärdigt tillförda resurser, är artikelns utgångspunkt. Intresset riktas mot lärarnas upplevelser i utvecklingsprocessen. Analysen bygger på kvalitativa processdata insamlade före, under och efter projektet. I tematisk analys urskildes tre aspekter av lärares upplevelser av tillit i skolutvecklingsprocessen som centrala; processtillit, kollegial tillit och kollektiv tillit. Övergripande processtillit och kollektiv tillit framstod som förutsättningar för arbetslagens uthållighet i utvecklingsarbetet. Kollegial tillit - tillitsfulla interpersonella relationer och professionellt förtroende lärarna emellan i arbetslaget - framstod som en särskild förutsättning för att lärares praktik skulle synliggöras, och att ett fördjupat kollektivt lärande därmed skulle kunna äga rum. Kollegial tillit och kollektiv tillit är begrepp som återfinns i organisationslitteraturen, medan processtillit är ett begrepp som artikeln förslår.

Abstract:
AbstractWe conducted a cropping systems experiment in central Pennsylvania, USA, to determine the effects of initial cover crop species and soil management on the abundance and composition of the ground-dwelling arthropod community. We hypothesized that we would detect legacy effects of the cover crops planted in year 1 of a 3-yr crop sequence on the arthropod community in the subsequent 2 yrs, and that these effects would be influenced by the intensity of tillage. We compared four systems in a factorial combination of perennial sod and legumes or annual cereal grain and legume as initial cover crops and moldboard or chisel plow tillage implemented in soybeans followed by maize in the subsequent 2 yrs. The entire experiment was initiated twice in adjacent locations, starting in 2003 (Start 1) and 2004 (Start 2). We quantified soil arthropod activity-density and community composition and identified all arthropods to order or family, and the ground and tiger beetles (Coleoptera: Carabidae) to species. In Start 1, but not Start 2, arthropod activity-density increased with each year following implementation of organic management. We observed few legacy effects of cover crop or tillage intensity on arthropod activity-density. The composition of the soil arthropod community was primarily defined by the initial cover crop in the first year, and by the interaction between cover crop and tillage intensity in the second and third year. A legacy effect associated with a yr-1 cover crop of cereal rye was observed for Scarabaeidae beetles and Formicidae (ants) in yr 2 and Carabidae beetles in yr 3 of Start 1, but not Start 2. Weed indicators contributed significantly to the variation in the soil arthropod community that was explained by the environment in yr 2 in Start 1, and in yr 3 in both Starts. Our observations support the concept that both immediate and legacy effects of management shape arthropod communities during the organic transition period, suggesting that transitioning systems could be managed in ways that conserve or enhance natural enemy populations.

Abstract:
This article discusses the design of the strut of a tillage machine in the form of an S-shaped power element, using flexible tubular elements (Bourdon springs). Racks of this type are proposed for copying the soil microrelief, maintaining the depth of soil cultivation using a hydraulic drive. The possibility of using the S-shaped rack of the tool of the tillage machine, using flexible tubular elements, to ensure the copying of the soil micro-relief, compliance with the specified working depth, has been experimentally proved. Evaluation of the sensitivity and traction capacity of the S-shaped load-bearing element of the rack will allow us to speak of the ability to create displacements within 120 mm and traction forces up to 1600 N, at a maximum pressure of 6 MPa. Keywords: SOIL TILLAGE, TOOL TILLAGE, FLEXIBLE TUBULAR ELEMENT, DEPTH OF SOIL TILLAGE

Abstract:
Abstract The African Union Malabo Declaration outlines goals to achieve sustainable production practices for economic growth in the agriculture sector by 2025. Conservation Agriculture (CA) practices represent a climate smart and resource friendly sustainable production system, and these need to be adopted and refined. This will be a paradigm shift for academics, experts and farmers who are embedded in the intensive external-input monoculture tillage systems. From our review of literature, recent history has shown that CA systems are successful and profitable while using less external inputs and expending less energy. Energy use can be reduced by 40% and labour needs by 50%-90%. Research has shown that CA farming is superior in terms of enhancing soil functions, biodiversity, beneficial insects, energy consumption, greenhouse gas (GHG) emissions and resilience to extreme climate events. Nitrogen and other essential elemental crop needs can be reduced by 10%-70% through CA systems. African research and farm testing have shown integrated CA cropping systems can control insect and weed pests while providing more diverse economic crops. For the paradigm shift to occur quickly, efficiently and economically, institutions need to lead change. Policy makers need to start strategic changes to research and institutions by initiating support programmes identified by innovative researchers and agricultural leaders that can move the Malabo dial towards the 2025 goals.

Abstract:
Studies of radical change pay more attention to early phases of the change processes than to later phases and implementation. Research that can contribute to a deeper understanding of factors that influence the implementation of such changes is therefore called for. The purpose of this chapter is to increase the insight and understanding of how trust and psychological safety impact implementation of radical changes. To meet this purpose, we raise the following research questions: 1) What are the differences and similarities between the concepts of trust and psychological safety? 2) How does trust and psychological safety influence implementation of radical changes in organizations? To answer the first question, we start by conducting a review of the literature on trust and psychological safety in part one. Although both concepts are widely used, the observable level of precision and understanding of the concepts varies. Our review reveals that the concepts are popular and quite closely related, yet there are also important differences worth noticing. To answer the second research question, we apply the insight from part one to discuss a conceptual case, well-known to many organizations in current business life; the implementation of radical new service technology. The discussion reveals that both trust and psychological safety play important, but somewhat different roles in top-down and bottom-up organized radical and adaptive change processes respectively.
