Performance of Mustard (Brassica juncea L.) Hybrids at Varying Crop Geometries in Low Hills of Himachal Pradesh

Abstract

Three mustard (Brassica junceaL.) hybridsviz., DMH 1, NRCHB 506 and PAC 432 were evaluated in comparison to Kranti grown at five planting geometries (30×10 cm, 30×15 cm, 60×10 cm, 45×10 cm, 45×15cm) duringrabi2010­ 11at CSKHPKV Hill Agriculture Research & Extension Centre, Dhaulakuan. Number of branches/plant were significantly more in PAC 432 (20.1) which were similar to DMH 1 (19.6).Plants were significantly taller at 30×10 cm (212.4 cm) whereas number of branches per plant was more at wider row spacing (45×15 cm and 60×10 cm). Hybrids DMH 1 and PAC 432 took 128 days to mature followed by NRCHB 506 (120 days) and Kranti (119 days). It was concluded that hybrid DMH 1 was highest yielder (14.65 q/ha) due to higher harvest index and more branching and should be grown at 30 cm×10­15 cm spacing or even at 45×10 cm geometry.
