A field experiment was conducted at Water Technology Centre, College farm, Rajendranagar, Hyderabad during kharif, 2015 to study the “Response of different varieties of aerobic rice (oryza sativa l.) under drip fertigation levels.” The experiment was conducted with three main treatments and four sub treatments. The main treatments were three rice varieties (RNR 15048, MTU 1010 and Anagha) and the sub treatments were four different fertigation levels (S0: Control, S75:90-45-30 kg N-P2O5-K2O ha-1, S100:120-60-40 kg N-P2O5-K2O ha-1, S125:150-75-50- N-P2O5-K2O ha-1. Drip irrigation was scheduled once in 3 days based on daily data of USWB class ‘A’ pan evaporimeter at 1.5 Epan. The amount of total irrigation water used including effective rain fall (277 mm) for different varieties were Anagha (9720 m3), MTU 1010 (9910 m3) and RNR 15048 (10110 m3) through drip irrigation. The differences in amount of water used were different for different varieties due to the differences in their crop growth period. The crop growth period noticed was 131, 139 and 151 days for Anagha, MTU 1010 and RNR 15048 respectively. The data on SCMR values at different plant growth stages, yield effecting parameters like no. of panicles m-2, panicle length (cm), no. of grains panicle-1, test weight (g), grain yield (kg ha-1), straw yield (kg ha-1) and dry matter production (kg ha-1) were recorded.
