Severe soil organic carbon (SOC) depletion is a major constraint in rainfed agroecosystems in India because it directly influences soil quality, crop productivity and sustainability. The magnitude of soil organic, inorganic and total carbon stocks in the semi-arid bioclimate is estimated at 2.9, 1.9 and 4.8 Pg respectively. Sorghum, finger millet, pearl millet, maize, rice, groundnut, soybean, ...

A quantitative understanding of yield response to water and nutrients is key to improving the productivity and sustainability of rainfed cropping systems. Here, we quantified the effects of rainfall, fertilization (NPK) and soil organic amendments (with straw and manure) on yields of a rainfed wheat-soybean system in the North China Plain (NCP), using 30-years' field experimental data (1982-201...

In order to assist in high-yield agricultural management multiple cropping systems, it is essential understand the link between rainy season onset and crops sowing dates, since considerably affects management, yield output. We built crop calendars derived from remote sensing products investigated dates of irrigated rainfed agriculture Western Bahia, a new important frontier Brazilian Cerrado. C...

most areas of the world where rainfall is limiting are characterized by low agricultural output and, ironically, high population growth rates that generate increased food de-mand. arid and semi-arid regions permit a range of vegetative biomass production, from rainfed crops to native pasture, and sparse steppe shrubs to true desert. given the harsh climatic conditions in areas such as west asia...

Abstract Corn and soybean are still strategic commodities that support people’s food needs. Rainfed land becomes the foundation for development of corn soybean. Crop intercropping system ( Turiman ) is an alternative planting technology innovation on rainfed land. The purpose this study was to determine added value production in consumption a rice field. conducted Batuliman Village, Candipuro D...

modeling of crop growth plays an important role in evaluation of drought impacts on rainfed yield, choosing an optimum sowing date, and managerial decision-makings. aquacrop model is a new crop model that developed by food and agriculture organization (fao), that is a model for simulation of crop yield based on “yield response to water“ with meteorological, crop, soli and management practices d...
