Field experiment was conducted during Kharif-2015-16 and 2016-17 at AICRP on Agrometeorology, Gandhi Krishi Vignana Kendra (GKVK), UAS, Bangalore to assess the effect of row spacing, varieties and date of sowing on growth and yield of pigeonpea. Significantly higher growth parameters viz., plant height (165.4 cm), leaf area index (2.10), leaf area duration (60.34 days) and crop growth rate (2.39 g m-2 day-1) and yield parameters (grain: 940 kg ha-1 and stalk: 4089 kg ha-1) were recorded in narrow row spacing (60 cm) compared to wider row spacing (90 and 120 cm). The TTB-7 recorded significantly higher growth viz., plant height (163.6 cm), no. of branches per plant (10.4), total dry matter accumulation per plant (65.33 g), leaf area per plant (3429 cm-2), leaf area index (1.81), leaf area duration (50.97 days) and crop growth rate (2.33 g m-2 day-1) and yield (grain: 914 kg ha-1 and stalk: 3427 kg ha-1) compared to BRG-2 variety. Significantly recoded higher growth viz., plant height (185.2 cm), no. of branches per plant (10.7), total dry matter accumulation per plant (71.26 g), leaf area per plant (4030 cm-2), leaf area index (2.12), leaf area duration (57.23 days) and crop growth rate (2.66 g m-2 day-1) and yield (grain: 1149 kg ha-1 and stalk: 3721 kg ha-1) parameters in May had sown pigeonpea than June and July. Significantly higher grain yield (1284 kg ha-1) and stalk yield (4980 kg ha-1) was observed in narrow row spacing (60 cm) with TTB-7 variety at May month sown crop (S1V1D1) which was on par with S2V1D1,S1V1D2 and S1V2D1. Significantly lower grain yield (344 kg ha-1) was recorded in wider row spacing (120 cm) with BRG-2 at July sown crop (S3V2D3) and lower stalk yield (1932 kg ha-1) was observed in wider row spacing (120 cm) with TTB-7 at July month sown crop (S3V1D3).
