Effect of Moisture Regimes and Gypsum Levels on Growth and Yield of Rabi Groundnut (Arachis hypogea L.)

A Field experiment was conducted in groundnut at Krishi vignan Kendra, Palem, Nagarkurnool district, Telangana state, India during rabi 2021 to study the influence of three moisture regimes viz 0.6, 0.8 and 1.0 IW/CPE ratios five gypsum levels G0- Control, G1- 300 kg ha-1, G2- 400 G3- 500 ha-1 G4- 600 replicated thrice. Experiment laid out split plot design. Among different levels, significantly higher values plant height (26.2 cm) 90 DAS, drymatter production (1803.4 3262.3 ha-1) DAS harvest were recorded with I3 (1.0 IW/CPE) @ (plant height- 27.4 (2092.7 4327.9 harvest. Similarly yield attributes- number filled pods plant-1- (60) shelling percentage- (67.1%) yield- pod halum (1977.4, 3253.4 respectively) also IW/CPE), whereas unfilled plant-1 (6.1) I1 (0.6 IW/CPE). 100-kernel weight found be non-significant. highest attributes G4 i.e., ha-1. The interaction effect significant respect production, Pods plant-1.
