Influence of plant population density on growth and yield of two blackgram varieties

A field experiment was carried out to evaluate the growth and yield performance of two blackgram varieties i.e., BARImash 3 and BINAmash 1 under three different population densities. The planting configurations were 40 x 10 cm2, 30 x 10 cm2 and 40 x 5 cm2 representing 25, 33 and 50 plants m-2. Both...

Summary:A field experiment was carried out to evaluate the growth and yield performance of two blackgram varieties i.e., BARImash 3 and BINAmash 1 under three different population densities. The planting configurations were 40 x 10 cm2, 30 x 10 cm2 and 40 x 5 cm2 representing 25, 33 and 50 plants m-2. Both the blackgram varieties showed identical results in LAI, CGR, NAR, RGR as well as grain yield. But planting density had significant effects on LAI and CGR of the blackgram varieties. The highest planting density showed the highest LAI and CGR but the highest grain yield was recorded from intermediate population density due to the highest number of pods per unit area. The NAR and RGR did not differ due to different population densities.
