摘要

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 mash bean Vigna mungo (L.) Hepper). This study was conducted for two consecutive years at the Agriculture Research Institute (ARI) under the existing semi-arid climatic, edaphic and water conditions of Quetta, Balochistan. Results revealed that plant population, pods plant(-1), grain yield plant(-1) and grain yield ha(-1) were significantly (p< 0.05 influenced by varying seed rates. However, other mentioned growth and yield attributes did not respond significantly. Statistically and numerically a maximum yield plant(-1) (20.98 g) and yield ha-1 (3120 kg) were obtained in applied seed @ 20 kg ha(-1). Whereas, the same was obtained for plant population and plant height in applied seed rate of 25 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 desirable population or planting density in the existing environmental conditions of Quetta. Results further revealed that only plant population plot(-1) (r= 0.481), and yield plant(-1) (r= 0.569) were significantly and positively correlated with grain yield ha(-1), while all other remaining growth and yield attributes exhibited insignificant association with grain yield ha(-1). Hence these two parameters i.e., planting density and grain yield plant(-1) should be given more consideration while deciding about selection criteria for mash bean under irrigated conditions of arid uplands of Balochistan.
