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 sub plot with three land configurations viz., L₁- Broad Bed Furrow, L₂- Ridges and furrow, L₃- Flat bed. In context with growth the irrigation regime 1.0 IW/CPE was found significantly superior over 0.6 IW/CPE, and it was found at par with 0.8 IW/CPE and 1.2 IW/CPE in respect of the growth attributes viz., plant height (cm), plant spread (cm), number of branches plant^-1, dry matter plant^-1 (g), number of nodules plant^-1 and weight of nodules plant^-1 (g) and for dry pod yield and dry haulm yield. The land configuration of broad bed furrow was at par with ridges and furrow and significantly superior to flat bed in respect the of the growth attributes viz., plant height (cm), plant spread (cm), number of branches plant^-1, dry matter plant^-1 (g), number of nodules plant^-1 and weight of nodules plant^-1 (g). 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 the yield viz., dry pod yield (q ha^-1) and dry haulm yield, biological yield (q ha^-1) and harvest index. For land configurations broad bed furrow recorded significantly superior dry pod yield (q ha^-1) and dry haulm yield, biological yield (q ha^-1) and harvest index over flat bed and found at par with ridges and furrows.
