Abstract:
A field experiment entitled, on “Studies on irrigation regimes and land configurations on growth and yield of summer groundnut (Arachis hypogaea L.)” was conducted at Agronomy Farm, Rajarshee Chhatrapati Shahu Maharaj College of Agriculture, Kolhapur (M.S.), India during summer, 2020. The experiment was laid out in split plot design with three replications and twelve treatment combinations consist of main plot with four irrigation regimes, viz., I₁- 0.6 IW/CPE, I₂- 0.8 IW/CPE, I₃- 1.0 IW/CPE, I₄- 1.2 IW/CPE, and three land configurations viz., L₁- Broad Bed Furrow, L₂- Ridges and furrow, L₃- Flat bed. The analyzed results indicated that application of water at 1.0 IW/CPE was at par with 0.8 IW/CPE and 1.2 IW/CPE significantly superior over 0.6 IW/CPE in respect of yield attributes and yield viz., number of pods plant^-1, weight of pods plant^-1 (g), dry pod yield (q ha^-1), dry haulm yield (q ha^-1), biological yield (q ha^-1), shelling (%), weight of 100 kernels (g), sound mature kernel (%) and harvest index (%). For land configurations broad bed furrow recorded significantly superior yield attributes and yield viz., number of pods plant^-1, weight of pods plant^-1 (g), dry pod yield (q ha^-1), dry haulm yield (q ha^-1), biological yield (q ha^-1), shelling (%), weight of 100 kernels (g), sound mature kernel (%) and harvest index over flat bed and found at par with ridges and furrows. The significantly highest WUE was obtained with irrigation regimes of 1.0 IW/CPE over 0.6 IW/CPE, and it was at par with 0.8 IW/CPE and 1.2 IW/CPE. For land configuration broad bed furrow recorded significantly superior WUE as compared to flat bed and found at par with ridges and furrows.
