Studies on seed production of mungbean (Vigna radiata) sown at different dates

To get maximum yield of kharif mungbean, a field experiment was conducted in a split plot design and replicated four times. Five varieties of mungbean viz., Pusa 105, Ganga 1, ML 682, PMB 14 and Pant Mung 4 were sown normal and late. Data on growth, development and yield components were recorded from ten randomly selected plants from each plots. Grain and straw yield were taken from the net harvested plot and computed to get kg ha(-1). Among the varieties, PMB 14 ranked first in terms of grain yield (549 kg ha(-1)) followed by Ganga 1 (521kg ha(-1)), ML 682(495 kg ha(-1)), Pant Mung 4 (475 kg ha(-1)) and Pusa 105 (438 kg ha(-1)). Highest grain yield (516 kg ha(-1)) was obtained in case of normal sowing whereas comparably lower yield (476 kg ha(-1)) was recorded under late sown condition. Significant interaction was noticed only in case of pods per plant. To obtain higher grain yield, mungbean should be sown at normal time (1st week of August) with genotype PMB 14.Most consistent performer under normal and delayed sowing was ML682. Pant Mung 4 was found to be most sensitive in delay planting than other tested varieties.
