Abstract:
The present investigation was conducted to study the response of interaction of different phosphorus levels and plant geometry on crop growth and yield of Green gram (Vigna radiata L.) in Uttrakhand conditions and this experiment was carried out by using Randomized Block Design (Factorial) with twelve treatments and each treatment was replicated at three times in a plot size of 3 m × 3 m (9m²) at Crop Research Farm, Maya College of Agriculture and Technology, Selaqui, Dehradun. The application of 60 kg phosphorus ha^-1 along with row spacing of 30×15 cm were significantly increased maximum plant height (75.23 cm), no. of branches plant^-1 (2.67), no of nodules plant^-1 (24.80), dry weight (30.89 g) and grain yield (1.51 t ha^-1) except C.G.R. (15.27 g/m²/day) and R.G.R. (0.04 g/g/day) which was recorded non-significant during interaction of treatments. The highest plant height (54.08 cm), Dry weight (20.34 g plant^-1), no. of branches plant^-1 (1.78), CGR (10.45 g m^-2 day^-1), RGR (0.03 g g^-1 day^-1) and grain yield (1.06 t ha^-1) were recorded in treatment R₁ (30 x 15 cm) whereas maximum no of nodules plant^-1 (15.67) and were observed in R₂ (45 x 15 cm) which was statistically at par with treatment R₁. Similarly the maximum growth and yield were recorded in P₃ (60 kg P₂O₅ ha^-1).
