Abstract:
Optimum plant population is a prerequisite for obtaining high yields of any crop. The aim of the study was to find out the optimum plant density of mungbean for obtaining high grain yield. Field investigations were undertaken at Punjab Agricultural University (PAU), Ludhiana, India on a loamy sand soil and at Asian Vegetable Research and Development Center (AVRDC), Taiwan on a sandy loam soil. At PAU, 40 plants m-2 at 25x10 cm spacing gave significantly higher grain yield than 33 plants m-2 at 30x10 cm spacing. Genotypes Pusa Vishal (selection from AVRDC material NM 92), SML 668 (selection from NM 94) and Pusa 9531 were on par in the grain yield and were better than UPM 98-1 and MH 96-1. Pusa Vishal and SML 668 had significantly larger seed size compared to Pusa 9531 and MH 96-1. At AVRDC, 20 plants m-2 sown at 50x10 cm spacing was the optimum for achieving higher grain yield and at higher plant densities, the yield tended to decrease. Lodging score was higher under higher plant densities. Genotypes NM 92 and VC 3890-A were superior to NM 94 and SML 134 in grain yield. Interaction between genotypes and plant density was non-significant for grain yield and other characters at both the locations.
