Firake, N.N. | Shinde, S.H. (Mahatma Phule Krishi Vidyapeeth, Rahuri (India)).
The research trials were conducted with irrigation depths 30, 50 and 70% cumulative pan evaporation and irrigation intervals (2, 3 and 4 days) were studied for its optimization in summer groundnut on sandy clay loam soil. It was observed that the drip irrigation to summer groundnut should be scheduled at 2 days interval @ 70% CPE to obtain maximum groundnut yields of dry pod, kernel, haulm and oil (33.23, 22.95, 43.10 and 10.82 q/ha, respectively). Amongst 70% CPE treatments the water use efficiency was found more in 2 days irrigation interval by 9.97% over 3 days irrigation interval and by 19.13% over 4 days irrigation interval.
