Online published on 10 April, 2012. Abstract A field experiment was conducted at Pantnagar during 2007–08 and 2008–09 to evaluate the effect of 3 dates of sowing (October 10, 20 and 30), 3 spacings (30 × 10 cm, 45 × 10 cm and 60 × 10 cm, and 3 mustard [Brassica juncea (L.) Czernj & Cosson] hybrids/varieties (‘Kranti’, ‘NRCHB-506’ and ‘DMH-1’). Yield attributes and seed yield were significantly higher in October 10 sowing compared to delayed sowings. The decrease in seed yield due to sowing on October 20 and October 30 over October 10 was to the tune of 8.7 and 29.2% during first year and 10.1 and 29.3% during second year, respectively. The hybrids ‘DMH-1’ and ‘NRCHB-506’ recorded 36, 35% and 24, 28% higher seed yield respectively, over ‘Kranti’. Spacing 45 × 10 cm had significant effect over 60 × 10 cm on seed yield during both the years. Hybrid ‘DMH-1’ recorded the highest economic returns when sown on October 10 at spacing of 45 × 10 cm. Nutrient uptake followed same trend as seed yield. Top Keywords Hybrid, Indian mustard, Oil yield, Seed yield, Spacing, Sowing date. Top |
