Abstract:

A Field experiment was conducted at Tamil Nadu Rice Research Institute, Aduthurai during Kharif, 2015 – 2016, to study the response of rice under different levels of irrigation through applied sprinkler system. Three levels of irrigation I1 - Surface irrigation method, I2 - Sprinkler irrigation at 125% pan evaporation, I3 - Sprinkler irrigation 150 per cent pan evaporation in main plot and five rice entries viz., ADT 43, ADT 45, Anna (R) 4, CORH 3 and CO(R) 51 were evaluated in strip plot design with three replications. The results revealed that in aerobic rice cultivation, grain yield of 3844 kg ha-1 was recorded in CORH 3 under surface irrigation method which was followed by CO(R) 51 with a grain yield of 3418 kg ha-1. Under sprinkler irrigation levels at 150% pan evaporation in CORH 3 recorded 25.1% lesser grain yield (2875 kg ha-1) when compared to surface irrigation method. Among the genotypes, CORH 3 hybrid performed better under sprinkler irrigation followed by CO(R) 51. The varieties ADT 45 and ADT 43 registered lower grain yield. Surface irrigation method utilized higher amount of irrigation water 1382 mm and 1335 mm whereas, sprinkler irrigation at 150% pan evaporation utilized 1097 mm and 1068 mm during kharif 2015 and 2016, respectively. Water saving of around 20.6 % and 20.1 % registered under sprinkler irrigation at 150% pan evaporation during kharif 2015 and 2016, respectively when compare to surface irrigation method.
