Abstract:
To study the effect of antitranspirants on growth and productivity of chickpea genotypes under rainfed and irrigated conditions, the experiment was taken during rabi season of 2021-22 and 2022-23 at MARS, Dharwad, Karnataka. The experiment was laid out in split-split plot design by taking two irrigation levels in main plot (I₁- Rainfed, I₂- Irrigation at pre flowering stage), three chickpea genotypes in sub plot (G₁- BGD111-1, G₂- DBGV-204, G₃- Super Annigeri) and three antitranspirants in sub-sub plot (A₁- No antitranspirant spray, A₂- Kaolin spray (5%), A₃- Atrazin spray (0.01%) at pre flowering and pod formation stage) with three replications. The pooled data of the experiment showed significant increase in plant height, number of branches, leaf area, leaf area index, number of pods plant^-1, test weight and seed yield with application of irrigation at pre flowering stage compared to rainfed condition. Among the genotypes, Super Annigeri recorded significantly higher number of branches and pods plant^-1. However, BGD 111-1 recorded significantly higher total dry matter production (29.97 g plant^-1) and seed yield of 1763 kg ha^-1. Among the antitranspirants, spraying of Kaolin (5%) at pre flowering and pod formation stage recorded significantly higher number of pods plant^-1 (51.1), test weight (21.90 g) and seed yield (1798 kg ha^-1) along with higher growth parameters. However, Atrazin spray (0.01%) at pre flowering and pod formation stage recorded lower values.
