Abstract :
A split factorial experiment was done in Bastam region in Shahrud during 2011-2012 crop year,using randomized complete design block with 3 replications to investigate the effect of planting data on some cultivars of mung bean. The experimental treatments included three planting dates (1st, 11th, and 21st of May, 2011), the application of humic acid spray at three levels (control, 40%, and 60%),and VC and Parto cultivars. Results from this study suggest that the second planting date provides the best conditions for reducing environmental effects and preserving the dry and fresh weights of the seed (53.57 g/shrub, and 174.97 g/shrub). In addition, the interaction between the planting date and dry weight of the seed, as well as between the planting date and fresh weight of the seed were significant at the level of 5% and 1%, respectively. The cultivars under planting date treatment showed statistical difference at the level of 1% in some traits namely 1000-seed weight, number of seeds per pod, and yield. Among the cultivars, the maximum 1000-seed weight (63.21 g) belonged to the Parto cultivar. In addition, the application of humic acid spray affected 1000-seed weight, number of seeds per pod, and seed yield in different cultivars at the level of 1%; in that, the maximum effect belonged to the application of humic acid 60% spray (66.20 g). On the other hand, such traits as protein content and ash content were not affected by any of the factors.
