Estimating the potential of rainfed agriculture in India: Prospects for water productivity improvements

Soil Testing as a Tool for On-Farm Fertility Management: Experience from the Semi-arid Zone of India

“…In the rainfed production systems, the importance of water shortage and associated stress cannot be overemphasized, especially in the semi-arid tropical (SAT) regions Passioura and Angus 2010;Rockström et al 2010;Sahrawat et al 2010a;Sharma et al 2010). However, apart from water shortage soil infertility is also the issue for crop production and productivity enhancement in much of the SAT regions of the world and Indian SAT is no exception (El-Swaify et al 1985;Black 1993;Zougmore et al 2003;Sahrawat et al 2007Sahrawat et al , 2010bSingh 2008;Bationo et al 2008;Twomlow et al 2008a;Bekunda et al 2010).…”

Meeting Up Millet Crop Water Requirements through Supplemental Irrigation in Semi-Arid Region of Borno State of Nigeria

“…The supplemental irrigation water of 84mm applied during booting and grain filling stages produced the highest yield. Sharma, et al (2010) reported that supplemental irrigation ranging from 50 to 200 mm per season is sufficient to mediate yield reduction by dry spells in most years and in rainfed systems.…”

Review on Rainfed Agriculture and Rainwater Harvesting Techniques

“…However, the study did not consider collecting the runoff for later use during dry spell. Sharma et al [17] estimated the efficiency of regional rain water use and incremental production due to supplementary irrigation for different crops. They concluded that "water harvesting and supplemental irrigation are economically viable at the national level.…”
