Response of mungbean varieties to different sowing dates.
In order to investigate the effect of sowing dates on yield and yield components of mungbean varieties a two years field experiment was conducted during 2005 and 2006 in Iran. The experimental design was split plot on the basis of randomized complete block design with four replications. Main plots consisted of three sowing dates (May 30, June 14, 29) and sub plots were also allocated to six varieties (Partow, vc1973, vc1178, vc4152, NM92 and Pusa1973). Results of combined analysis showed that seed yield was significantly affected by sowing dates. The maximum seed yield (102.9 g m(-2)) was obtained in June 29 sowing date because the number of pods per plant and 1000-seeds weight were also increased. Varieties also responded significantly towards yield and yield components. The maximum seed yield (114.9 g m(-2)) was produced by vc4152 variety. Interaction effects of sowing dates and varieties were found significant, vc4152 variety sowing on June 29 gave the highest seed yield (134.7 g m(-2)).
