Abstract (sommario):
This study was carried out to compare the diversity in weed phenological events, seed production and seed rain in a dryland and an irrigated agroecosystems of Indian dry tropics. Diverse weed phenological patterns were noted in dryland and irrigated agroecosystems. During winter season, in dryland agroecosystem, dominant weeds like Anagallis arvensis, Chenopodium album and Phalaris minor showed approximately one month early germination and vegetative stage compared to irrigated agroecosystem for same species. The annual flower, fruit and seed production were higher in the dryland agroecosystem

Abstract (sommario):
Abstract The use of the ecosystem services approach for ecosystem management, including the valuation of ecosystem services, has grown in recent decades. Although a common framework is used, each ecosystem has its own characteristics. The agroecosystem, for example, is an anthropised ecosystem where ecosystem service flows are highly interrelated with the environment, positively or negatively. Therefore, agroecosystem services are usually accompanied by disservices. The valuation of agroecosystem services and disservices requires adaptation of existing ecosystem services paradigms to accommoda

At the end of the growing season of the first year of life of perennial legumes, the highest soil moisture - 27.45% was observed in the agroecosystem of alfalfa, and the lowest - 24.14% - in the agroecosystem of the horned lily. The coefficient of water use by agroecosystems of legumes of perennial grasses in the first year of their growing season was 455.1-1738.0. The smallest coefficient of water use was in the agroecosystem of the white melilot, and the highest in the eastern goat's rue.

Abstract (sommario):
Agroecosystem health refers to the extent to which a healthy agroecosystem can meet socioeconomic and biophysical needs of all residents over time. According to the attempts at assessing agroecosystem health, agroecosystem health depends on both functional and structural characteristics at regional level. However, both functional and structural characteristics have been altered from their natural state by industrialization and urbanization. Thus, this study reports a system-based assessment index to evaluate the health statue of agroecosystem in Guangzhou, South China. Agroecosystem health ind

Abstract (sommario):
Agroecosystems form a natural ecosystem component, allowing the proper classification of a regional biome at a global scale. It is important to view agroecosystems from a micro-environmental perspective given that they are characterised by a combination of factors, including the interaction of soil–plant–atmosphere conditions, which are largely responsive to human management practices. The published literature generally provides a limited explanation of the multidimensional nature of agroecosystems. In combination, agroecosystem practices promote efficient water use and nutrient cycling in def

Globally, mankind is facing an increasingly severe challenge of climate change, and the vast majority of countries are making sustained efforts to solve the problem. Agroecosystem is not only an important source of greenhouse gas emissions, but also has a large potential of carbon sink, so research on greenhouse gas mitigation and carbon sink in agroecosystems is an important initiative to address the challenge of climate change. However, the current domestic research on carbon sinks mainly focuses on forests, grasslands and oceans, and there are relatively few studies on carbon sinks in agroe

Abstract (sommario):
If upland rice production is to be sustained on sloping land, soil erosion and fertility decline must be addressed. Where soil profiles are deep, hedgerows of Gliricidia sepium and Cassia spectabilis, planted on the contour, reduce soil erosion by promoting terrace formation and overcome fertility depletion by providing nutrient rich biomass. G. sepium and C. spectabilis established by seed survived better than by cuttings. Although increased hedgerow biomass was initially obtained when both species were intercropped, intense competition was observed in established hedgerows. Consequently, mix

Our earth is currently undergoing unprecedented human induced climate change, which is expected to drive widespread changes in species distributions and abundances that will affect natural pest suppression. Recent studies have suggested that climate change may cause changes to predator and herbivore assemblages in ways that alter multi-trophic food webs and affect the stability of ecosystems. Moreover, higher temperatures and increased climatic variability are expected to induce differential responses from predators and their prey that will undoubtedly disrupt species interactions.

Abstract (sommario):
A major goal in Israeli and U.S. agroecosystems is to maximize nitrogen availability to crops while minimizing nitrogen losses to air and water resources. This goal has presented a significant challenge to global agronomists and scientists because crops require large inputs of nitrogen (N) fertilizer to maximize yield, but N fertilizers are easily lost to surrounding ecosystems where they contribute to water pollution and greenhouse gas concentrations. Determination of the optimum N fertilizer input is complex because the amount of N produced from soil organic matter varies with time, space an

Abstract (sommario):
Maize productivity in Indonesia was still low (5.241 tons/ha) compared to the average of the ten largest maize producing countries in the world (6.179 tons/ha). The potential for maize on the island of Madura is approximately 360,000 hectares. The potential for maize cultivation in Madura continues to decrease in land quality due to improper land clearing and land-use change. The purpose of this research was to make a map of land suitability for maize using Remote Sensing Data and Geographic Information System (GIS). The land suitability method for maize plants used satellite imagery as a data

Abstract (sommario):
Cocoa production has a long history in Ghana, originating in the late nineteenth century. Since then, cocoa production has seen significant changes. Originally, cocoa was cultivated in newly cleared forests in which many forest trees were preserved as shade trees. Cocoa is ideally suited to these conditions and produces high yields with minimum investment in labour and inputs. However, over time, as the forest conditions change, the cost of cultivating cocoa has increased and yields have declined. As long as new forest frontiers exist, farmers have continued to move into these areas, which hav
