Abstract
Food security and reducing poverty for the ever-growing population in India is a challenging task. India’s agricultural land is 142 million ha with 135% cropping intensity (NAAS, 2009) and 60% is rainfed, which is characterized by water scarcity, land degradation, low use of inputs and low productivity. Agricultural productivity of these areas oscillates between 0.5 t/ha and 2 t/ha with an average of 1 t/ha (Rockstrom et a l, 2010; Wani et al., 2011a, b). Of the total agricultural area, the 40% that is irrigated land contributes 55% of total food production in the country (Gol, 2012) but on the other hand it consumes almost 70% of freshwater resources and has left limited scope for further expansion of the irrigated area (Central Water Commission, 2005; CGWB, 2012). Thus, achieving food security of the country at present and in the future is largely dependent on rainfed agriculture (Wani et al., 2009, 2012a). Despite several constraints and limitations of rainfed areas, huge untapped potential exists for enhancing crop yield through improved land, water, nutrient and other natural resource management options (Rockstrom et al., 2007; Garg et al., 2012a, 2013; Wani et al., 2012a; Singh et al., 2014)...

Acknowledgement: | We sincerely acknowledge the funding support from the Government of Karnataka and the DoA for implementing the Bhoochetana programme in Karnataka. Our sincere thanks go to the Karnataka State Natural Disaster Management Centre for providing daily rainfall data of different taluks of the 30 districts of Karnataka over a 4-year period between 2009 and 2012. We acknowledge the help and support received from DoA staff, farm facilitators and ICRISAT field staff for conducting crop cutting experiments. Details of total fertilizer consumption (macro and micro) and area coverage under the Bhoochetana programme in each year was collected and provided by the DoA. The authors are also grateful to the National Bureau of Soil Survey and Land Use Planning (NBSS&LUP) and the Bureau of Statistics and Economics for providing data on soil physical parameters and the market price and cost of cultivation for different crops. |
