Abstract:
A field experiment was conducted at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to study the “Effect of date of sowing and plant geometry on growth and yield of mustard [Brassica juncea L. (Czern and Coss)]” during Rabi season of 2020-21. Total fifteen treatment combinations comprising three levels of date of sowing in main plot viz., 20^th October (D1), 30^th October (D2) and 10^th November (D3) and five levels of plant geometry in sub-plot viz., 30 cm × 15 cm (G1), 45 cm × 15 cm (G2), 45 cm × 30 cm (G3), 60 cm × 15 cm (G4) and 60 cm × 30 cm (G5) laid out in split plot design with three replications. Plant height, number of secondary branches per plant, leaf area per plant, number of siliquae per plant, 1000-seeds weight, seed yield, straw yield, oil yield, net realization (₹ 69922/ha) and BCR (3.05) showed significantly higher values were obtained when crop was sown on 30^th October. However, it was statistically on par with 20th October sowing. Significantly higher plant population/ha and plant height were under close plant geometry of 30 cm × 15 cm. On the contrary, numbers of secondary branches per plant, leaf area per plant, number of siliquae per plant and 1000-seeds weight were recorded significantly higher under wider spacing of 60 cm × 30 cm (G5). Significantly higher seed yield (2100 kg/ha), straw yield (4372 kg/ha), oil yield (841 kg/ha), net realization (₹ 72240/ha) and BCR (3.07) were obtained 45 cm × 15 cm spacing being comparable with 30 cm × 15 cm spacing.
