Impact of Yield Attributes and Yields of Pigeonpea (Cajanus cajan (L.)) Varieties under Different Sowing Windows

An agro-meteorological investigation was undertaken to determine“the impact of crop yield attributes and yield of pigeonpea (Cajanus cajan) varieties under different sowing windows” during kharif, 2017-18 and 2018-19 at Department of Agricultural Meteorology, College of Agriculture, Pune. In this context, an experiment was laid out in split plot design with three replications. The treatment comprised of four varieties viz., Vipula, Rajeshwari (Phule T 0012), BDN 711 and ICPH 2740 as main plot and four sowing windows viz., 24th, 26th MW, 28th and 30th MW as sub plot treatments. Yield contributing characters viz., number of pods plant-1 (149.5 and 143.0), weight of pods plant-1 (113.8 and 107.6 g) and 100 seed weight (10.79 and 10.75 g) were found significantly higher in var. ICPH 2740 over var. Vipula, Rajeshwari and BDN 711.Grain yield (26.59 and 28.14 q ha-1) and stalk yield (39.61 and 36.7 q ha-1) were significantly higher in var. ICPH 2740 followed by var. Rajeshwari, Vipula and BDN 711.On the other hand, Grain yield (24.31 and 22.86 q ha-1) and stalk yield (63.6 and 61.8 q ha-1) was higher in 24th MW sowing window during the year 2017-18 and 2018-19, respectively.
