Effect of Irrigation Levels and Intervals on Groundnut (Arachishypogaea L.) Cultivars under Drip System

Abstract

The field experiment entitled “effect of irrigation levels and intervals on groundnut (Arachishypogaea L.) Cultivars under drip system” was conducted at Instructional Farm, S.K. Rajasthan Agricultural University, Bikaner during Kharif 2019. Irrigation level of 0.80 PE gave higher dry matter accumulation, pods plant-1 (44.13), kernels pod-1 (2.38), pod yield (3117 kg ha-1), haulm yield (4081 kg ha-1), biological yield (7199 kg ha-1), test weight (446.58 g) and oil yield (978.32 kg ha-1) followed by 0.60 PE. Alternate day irrigation intervals gave higher dry matter accumulation, crop growth rate, pods plant-1 (43.55), kernels pod-1 (2.36), pod yield (2993 kg ha-1), haulm yield (3986 kg ha-1), biological yield (6980 kg ha-1), test weight (443.22 g) compared to 3 days irrigation intervals. Groundnut cultivars HNG-123 gave higher pods plant-1 (43.45), kernel pod-1 (2.39), pod yield (2925 kg ha-1), haulm yield (3977 kg ha-1), biological yield (6902 kg ha-1) and test weight (470.58 g) compared to all other cultivars.
