Abstract:

Field experiment was conducted at Agronomy and ACRIP Research Block, Department of Agronomy, Agricultural College and Research Institute, (Tamil Nadu Agricultural University, Coimbatore) Madurai during kharif season, 2007, to study the influence of rice variety, hybrid, irrigation regimes under raised bed and drip fertigation. The study revealed that growth and yield contributing characters were higher in CO(R)H 3 with raised bed (RB) 120cm bed width (BW) – Maintaining water in furrow and recorded highest grain yield of 6.452 t ha-1. The next best treatment was ASD 16 RB 120 cm BW maintaining water in furrow (5.968 t ha-1) and it was on par with SRI (5.876 t ha-) and drip irrigation with CO(R)H 3 + RB 120 cm BW once in 2 days-100 % PE) (5.847 t ha-1). Increased water was used in ASD 16 with RB 90, 120 cm BW maintaining water in furrow and lesser water used was recorded under CO(R)H 3 with RB 90 cm BW –Drip Irrigation (DI) -100 % PE-daily and Once in 2 days. Higher water saving is recorded under drip irrigation treatments. The highest water use efficiency was recorded in treatment combination CO(R)H 3 RB 120cm BW- DI -100 % PE-Once in 2 days. Interaction effect of CO(R)H 3 with RB120cm BW– Maintaining water in furrow recorded highest gross, net and BC ratio. Overall results of the study indicated that CO(R)H 3 with Raised Bed 120cm Bed Width – Maintaining water in furrow performed better and wherever water scarcity occur better go for The highest water use efficiency was recorded in treatment combination CO(R)H 3 RB 120cm BW- DI -100 % PE-Once in 2 days drip irrigation because water use efficiency and water saving was higher in drip irrigation.


Keywords: RB-Raised Bed, BW-Bed width, DI -Drip Irrigation and SRI- System Rice Intensification.
