Abstract
Growth parameters like leaf area (LA) and total dry mass (TDM) production, crop growth rate (CGR), relative growth rate (RGR), net assimilation rate (NAR) and average growth rate (AGR) were compared in six varieties (3 mungbean and 2 mashbean) under (30° 541 N 75°481 E 247m) to identify limiting growth characters for efficient application of physiology breeding for higher yield. Results indicated that relatively smaller proportion of TDM was produced before flower initiation and major bulk after anthesis. The maximum CGR was recorded during pod filling stage (40-50DAS) due to higher LA. Plant characters such as LA and CGR contributed to the higher TDM production. High yielding varieties possessed larger LA, higher TDM production ability, superior CGR at all the growth phases and high RGR at vegetative stage which would result in higher productivity.
