Effect of drip irrigation on growth and yield of direct seeded rice (Oryza sativa L.)

Abstract

The experiment was conducted during Kharif season of 2012-13 in H-Block of University Farm, G.B. Pant University of Agriculture and Technology, Pantnagar. Eight treatments were taken where five of the treatments were 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. Results revealed that T4- Drip irrigation at 20% CPE on 1 day gap have performed better regarding the growth parameter as well as in terms of grain and straw yield by obtaining higher grain yield (8076.25 kg ha-1) and straw yield (8651.90 kg ha-1) which is statistically superior then conventional transplanted rice and any other treatments.
