Effect of drip irrigation on economics of direct seeded rice (Oryza sativa L.)

Abstract

The field experiment was conducted during kharif season of 2012-13 in H-Block of University Farm, G.B. Pant University of Agriculture and Technology, Pantnagar. During the field experiment 8 treatments were taken. Among those treatments five of the treatments were associated with drip irrigation treatment in direct seeded rice which was given in accordance to different per cent of cumulative pan evaporation (CPE) with different days of interval and control treatment was taken as conventional transplanted rice. The results from the experiment revealed that T4- Drip irrigation at 20% CPE on 1 day gap have the highest net return of ` 91684.80 ha-1 which was followed by T5 - Direct seeded rice with drip irrigation at 30% CPE on 2 day gap by obtaining ` 88161.96 ha-1. The benefit in terms of B:C ratio was also highest due to T4 - Direct seeded rice with drip irrigation at 20% CPE on 1 day gap (3.16) while comparing to all the other treatments allocated in the given experiment.
