Online published on 23 December, 2016. Abstract A field investigation was carried out at N. M. College of Agriculture, Navsari Agricultural University, during summer 2014 to evaluate effect of different row spacing and weed management practices on growth and yield of summer greengram (Vigna radiata L.) under South Gujarat condition. Based on field experimentation, it was found that various row spacing treatments had significant effect on growth and yield attributing characters like, plant height, number of branches per plant, dry matter production per plant and number of pods per plant, which caused significant effect on seed and stover yields of greengram crop. In most of the cases, treatment S3 (60 cm x 10 cm) was found superior than other spacing, but the narrow row spacing of summer greengram i.e. (30 cm x 10 cm) recorded significantly higher seed and stover yield of greengram under South Gujarat condition. Almost all the growth and yield attributing characters like, plant height, number of branchesper plant, dry matter production per plant, number of pods per plant, number of seeds per pod and pod length were significantly influenced by different weed management practices. In most of the cases, treatment W1 (Two hand weeding and interculturing at 20 and 40 DAS) was found superior than rest of the treatments, but remained at par with W3 (Pendimethalin @ 1.00 kg ha−1 as PE + one hand weeding at 40 DAS) and W4 (Pendimethalin @ 1.00 kg ha−1 as PE + Quizalofop-ethyl @ 0.05 kg/ha as PoE at 20 DAS). Similar trend of response of treatment was recorded for seed and stover yield of summer greengram. Top Keywords Greengram, Spacing, Weed management, Yield. Top |
