Effect Of Seed Rate On Growth, Yield Components And Yield Of Mungbean Grown Under Irrigated Conditions In The North Of Khuzestan

ABSTRACT:A field experiment was carried out to investigate the effects of six different seed rates viz., 15,17.5, 20, 22.5, 25 and 27.5 kg ha-1 on the growth, yield and yield attributes of mungbeanVignamungo (L.) Hepper). This study was conducted for two consecutive years at the AgricultureResearch Institute (ARI) under the existing semi-arid climatic, edaphic and water conditions ofQuetta, Khuzestan. Results revealed that plant population, pods plant-1, grain yield plant-1 andgrain yield ha-1 were significantly (p < 0.05 influenced by varying seed rates. However, othermentioned growth and yield attributes did not respond significantly. Statistically and numerically amaximum yield plant-1 (20.98 g) and yield ha-1 (3120 kg) were obtained in applied seed @ 20 kgha-1. Whereas, the same was obtained for plant population and plant height in applied seed rate of25 kg ha-1. However, maximum number of branches plant-1 (4.22) was received for applied seeds @15 kg ha-1. Therefore, seed @ 20 kg ha-1 seems optimum which could be due to the most desirablepopulation or planting density in the existing environmental conditions of Quetta. Results furtherrevealed that only plant population plot-1 (r=0.481), and yield plant-1 (r=0.569) were significantlyand positively correlated with grain yield ha-1, while all other remaining growth and yield attributesexhibited insignificant association with grain yield ha-1. Hence these two parameters i.e., plantingdensity and grain yield plant-1 should be given more consideration while deciding about selectioncriteria for mungbeanunder irrigatedconditions of Khuzestan.
