Evaluation effect of sowing date and plant density on yield and yield components of Mung bean in Jiroft conditions
The effect of sowing date and plant density was studied on yield and yield components of mung bean cv. Parto in research farm of Islamic Azad University of Jiroft in 2010-2011 in a split plot experiment based on a Randomized Complete Block Design with three replications. The main-plots was devoted to sowing date at four levels (June 29, July 6, July 12 and July 20) and the sub-plots was devoted to density at three levels (10, 20 and 30 plants m-2). Analysis of variance revealed that sowing date significantly influenced plant height at the 1% level of probability and the number of pods per plant, the number of grains per pod, grain yield and biomass at the 5% level of probability. The effect of plant density was significant on the number of pods per plant and biomass at the 5 and 1% probability levels, respectively. The interaction of sowing date and plant density was significant only for plant height and biomass yield. The highest grain yield (1001 kg ha-1) was obtained from July 6 and the lowest one (714.3 kg ha-1) from July 20. Although the effect of plant density was not statistically significant on grain yield, the highest grain yield (907.98 kg ha-1) was related to the density of 30 plants m-2. Considering the one-year results, the best sowing date can be regarded as to be July 6 with the density of 10 plants m-2 under the regional conditions of Jiroft.
