Abstract
A field experiment was carried out to
study the effect of sowing dates on growth attributes and yield of blackgram (Vigna mungo L. Hepper). Seeds of two blackgram
varieties (BARI Mash-1 and B-10) were sown with four different dates (03
August, 13 August, 23 August and 02 September, 2006). Results indicated that total
dry matter and leaf area index were increased with increasing plant age then
again decreased. Leaf area ratio and leaf weight ratio were decreased with
increasing plant age. Leaf area index, dry matter production and harvest index
seemed to be important in improving seed yield of blackgram. Yield and yield
components were higher in local variety B-10 than the BARI Mash-1. Plant
height, seeds plant-1, pod dry weight plant-1, total dry
matter plant-1 and seed yield were higher in 13 August sowing than
the other sowings.
