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...

EPTD Discussion Papers contain preliminary material and research results, and are circulated prior to a full peer review in order to stimulate discussion and critical comment. It is expected that most Discussion Papers will eventually be published in some other form, and that their content may also be revised. ACKNOWLEDGMENTS The authors would like to thank Susanne Neubert and John Pender for h...

Since rainfed rice fields typically lack nutrients, frequently experience drought, and require more fund to support farming operations, the production results become erratic unpredictable. This research aims construct location-specific yield predictions in among Sumbing-Sindoro Toposequence, Central Java, using a Bayesian method. study is survey with an exploratory descriptive methodology based...

With the growing recognition of the possibility of global climate change, an increasing emphasis on world food security in general and its regional impacts in particular have come to forefront of the scientific community. Agriculture production of rainfed regions is expected to suffer severe water crisis due to delayed monsoon, uneven distribution of rain as a result of climate change. The impa...

The role of urban agriculture in global food security is a topic of increasing discussion. Existing research on urban and peri-urban agriculture consists largely of case studies that frequently use disparate definitions of urban and peri-urban agriculture depending on the local context and study objectives. This lack of consistency makes quantification of the extent of this practice at the glob...

Potato productivity in the northeastern US has been relatively constant for over 50 years, raising questions about what factors are limiting productivity. Research was initiated in 2004 to identify key constraints to potato productivity by evaluating Status Quo (SQ), Soil Conserving (SC), and Soil Improving (SI) cropping systems under both rainfed and irrigated management, and it was found that...

Background: Cotton with coevolving pests has been grown in India more than 5000 years. Hybrid cotton was introduced in the 1970s with increases in fertilizer and in insecticide use against pink bollworm that caused outbreaks of bollworm. Hybrid Bt cotton, introduced in 2002 to control bollworm and other lepidopteran pests, is grown on more than 90 % of the cotton area. Despite initial declines,...

introduction soil infiltration rate is the major soil hydraulic property which can be affected by the soil physical characteristics and management practices. the use of land can affect various soil properties such as physical and hydraulic properties. differences of the hydraulic soil characteristics such as infiltration rate in various land uses can affect their potential to runoff production ...

The success of the Green Revolution in closing the gap between world population and food production was principally achieved by increasing crop productivity in favorable areas. However, this success has been limited in the rainfed systems, which are prone to frequent droughts and other abiotic stresses. Worldwide, drought affects approximately 23 million hectares of rainfed rice. Varieties comb...
