Assessing Crop and Water Productivity Performance of Different Crops and Cropping Systems

Background: Freshwater in sufficient quantity and adequate quality is a prerequisite for human societies natural ecosystems. To adequately feed 9.3 billion people 2050, consumptive water use (i.e. transpired water) by all food fodder crops needs to increase from its present estimated level of 7000 km3/year 12,586 km3/year. However, fresh resources are increasingly getting scarce because increased competition among multitude users. Getting agriculture perform with progressively smaller allocation renewable will remain challenge on global scale. meet the there an urgent need improve crop productivity ensure sustainability agriculture. Methods: An experiment was carried out at village Menawali, Hanumangarh, Rajasthan during both kharif rabi seasons assess productivity, economics, N-uptake different crops. area 187 ha comprising 25 farmers irrigated common irrigation channels were selected collect information. The information required i.e. soil, management, growth, phonological, yields, balance, efficiency each collected 15 farmers. Bt-cotton clusterbean wheat Indian mustard prominent crops, cotton-wheat, cotton-mustard, clusterbean-wheat clusterbean-mustard major cropping sequences study region. Result: In season, gave higher economic yields than amongst season 4255, 1778 kg/ha, respectively. yield varied 3741-6514 kg/ha cotton-wheat (6218 kg/ha), intermediate (5785 kg/ha) lower cotton-mustard (3741 (3308 kg/ha). (₹1181.2 mm) sequence had highest use. Clusterbean-wheat system recorded (16.5 followed (14.9 mm). (₹456/ha most profitable fetched net return (₹383/ha
