abstract drought is one the most complicated and unknown natural disasters and rainfed agriculture is often the first sector to be affected by drought. in this research, we consider the drought monitoring from both meteorological and agricultural points of view. we have selected standardized precipitation index (spi) among the meteorological indices, with a one month time scale for the synoptic...

BACKGROUND Drought is a major limitation to plant productivity. Various options are available for increasing water availability and sustaining growth of crop plants in drought-prone environments. SCOPE After a general introduction to the problems of water availability, this review focuses on a critical evaluation of recent progress in unravelling mechanisms for modifying plant growth response...

information required to benchmark yields. These include Growers, breeders and policy makers require benchmarks to measure performance in regard to management of the crop, genetic improvement and prospects for investment and employment. Cropping systems are difficult to benchmark because of the unpredictable nature of the climate. In this paper previous attempts to benchmark sugarcane production...

in the vast rainfed regions, diminishing returns from the public irrigation systems, climate change induced chaotic fluctuations in the hydrologic regimes and a large demand-supply gap in non-cereal food items are all compelling reasons for the need to realise the production potential of rainfed farming areas. Little control over the rainfall and absence of suitable mechanisms for storing or co...

Water harvesting systems have improved productivity in various regions in sub-Saharan Africa. Similarly, they can help retain water in landscapes, build resilience against droughts and dry spells, and thereby contribute to sustainable agricultural intensification. However, there is no strong empirical evidence that shows the effects of intensification of water harvesting on upstream-downstream ...

Drought, water, and nitrogen (N) losses have always been great challenges for agricultural production in subtropical regions of China. To study appropriate irrigation regimes reasonable N applications, a field experiment was conducted summer maize (Zea mays L.) from 2018 to 2019. Two treatments, namely, rain-fed supplementary irrigation, were designed, five levels fertilizer applied. The differ...
