A field experiment was conducted during kharif 2016-17 to test the impact of hydrogel application on growth, yield and economics of rainfed castor at Zonal Agricultural and Horticultural Research Station, Babbur Farm, Hiriyur, Karnataka. The superabsorbent polymer as pusa Hydrogel at 50% RDH, 100% RDH and 150% RDH and control were set as treatments. The results of study indicated that soil application of pusa hydrogel @ 100% RDH resulted in significant improvement on plant height and number of capsules/spike which reflected in higher seed yield (1776 kg/ha) followed by 50% RDH (1652 kg/ha) as compared to Control (1242 kg/ha). However, application of 50% and 100% RDH recorded similar B:C ratio (2.0). Hydrogel application beyond 100% RDH reduced the seed yield of castor by 11% and brought down the B:C ratio drastically (1.6). Next best treatment is found to be soil application of pusa hydrogel @ 50% RDH. From the above results, it can be inferred that soil application of hydrogel may be a significant practice to increase the yield of castor under rainfed conditions.
