Abstract Scientific knowledge, societal debates, and industry commitments around sustainable cocoa are increasing. Cocoa agroforestry systems supposed to improve the sustainability of production. However, their combined agronomic, ecological, socio-economic performance compared monocultures is still largely unknown. Here we present a meta-analysis 52 articles that directly monocultures. Using an inductive, multi-dimensional approach, analyzed differences in total system yield, economic...
Agriculture is a major contributor to greenhouse gas (GHG) emissions and one of the sectors most vulnerable climate change. Mulching, application an organic layer agricultural field, promising practice, with aim reducing evaporation, preventing soil erosion stabilising yields. While mulching has become popular research topic in recent years, little known about its effects on change adaptation GHG emissions. We conducted weekly measurements nitrous oxide (N2O) analyzed related parameters,...
SUMMARY Agroforestry systems (AFS) can serve to decrease ecosystem carbon (C) losses caused by deforestation and inadequate soil management. Because of their shade tolerance, cacao plants are suitable be grown in AFS, since they combined with other kinds trees shrubs. The potential for C sequestration farming depends on various factors, such as management practices, stand structure plantation age. We compared conventionally organically managed monoculture (MCS) AFS Sara Ana (Bolivia) respect...
The biotic release of nitric oxide (NO), a greenhouse gas, into the atmosphere contributes to climate change. In plants, NO plays significant role in metabolic and signaling processes. However, little attention has been paid plant-borne portion global emissions. Owing growing significance flooding events caused by change, extent plant emissions assessed under low-oxygen conditions for roots intact plants. Each examined species (tomato, tobacco, barley) exhibited highly oxygen-dependent...
Abstract Climate change is a growing threat to agriculture globally, with most substantial impacts expected in tropical smallholder systems such as cocoa farms West Africa. Cocoa agroforestry widely believed enhance resilience climatic extremes due protection and favourable microclimate under the shade trees. Morphological traits of many locally used tree species their specific contribution for climate-resilient production remain unclear. Therefore, aboveground morphology sub canopy eight...
Abstract. Legumes in crop rotations are considered an ecological intensification management practice to reduce nitrogen (N) losses the environment. However, studies on N allocation and loss adjacent sites with same pedoclimatic conditions but different histories, i.e. organic farming (OF) frequent legume cultivation occasional fertilizer input, compared integrated (IF) synthetic fertilizers, have remained scarce. Here, we quantified field (ammonia, nitrous oxide, dinitrogen, nitrate...
An evaluation of the susceptibility different N management systems to nitrogen (N) losses into environment requires either in-situ determination individual components balance or recovery fertilizer in plants and soil. For both aspects, 15N methods are essential as gas flux method (15NGF) is only widespread for dinitrogen (N2) emissions, labelled fertilizers can be used assess allocation soil.To evaluate influence history on losses, we quantified loss pathways (NH3, N2O, N2, NO3- leaching),...
Abstract Understanding water stress signaling mechanisms and screening for tolerant cocoa cultivars are major challenges when facing prolonged dry rainy seasons in cocoa-producing areas. While abscisic acid (ABA) proline supposed to enhance drought tolerance cocoa, the role of polyamines remains unclear. The aim this study was investigate biochemical response phenological adaptation ( Theobroma cacao ) on different soil moisture conditions, with a focus short-term (20 days) long-term (89...
The intensification of food production systems has resulted in landscape simplification, with trees and hedges disappearing from agricultural land, principally industrialized countries. However, more recently, the potential agroforestry small woody features (SWFs), e.g., hedgerows, woodlots, scattered groups trees, to sequester carbon was highlighted as one strategies combat global climate change. Our study aimed assess extent SWFs embedded within landscapes Germany, estimate their stocks,...
Abstract Agroforestry is a land-use system that combines arable and/or livestock management with tree cultivation, which has been shown to provide wide range of socio-economic and ecological benefits. It considered promising strategy for enhancing resilience agricultural systems must remain productive despite increasing environmental societal pressures. However, agroforestry pose number challenges experimental research scientific hypothesis testing because their inherent spatiotemporal...
Cocoa beans are produced all across the humid tropics under different environmental conditions provided by region but also season and type of production system. Agroforestry systems compared to monocultures buffer climate extremes therefore provide a less stressful environment for understory cocoa, especially seasonally varying conditions. We measured element concentration as well abiotic stress indicators (polyamines total phenolic content) in derived from five comparing agroforestry two...
A greenhouse experiment with sorghum sudangrass (Sorghum bicolor × Sorghum sudanense) and maize (Zea mays) was conducted to assess information on differences in their nitrogen fertilizer utilization when used as energy crops. The aim contribute the scarce data an crop regards derived from (NdfF) plant’s biomass (FNU). were each grown eight bags of 45 L volume harvested at maturity after 154 days. Each treatment further divided a control (four each) that did not receive N fertilization...
