Abstract:
Unfavourable environmental condition is the main cause of low greengram yield in Odisha. An experiment was conducted at Bhubaneswar to quantitatively establish the relationship of environment as varied with the dates of sowing (20 January, 30 January, 9 February and 19 February) with growth, phenology and yield of four greengram varieties [PDM-139(SAMRAT), IPM 205-7 (VIRAT), IPM 02-14 and OUM11-5]. Greengram yield was high with late sowing on 19 February (487 kg / ha) and it was the lowest with 20 January sowing (404 kg / ha). The decline in yield was mainly due to reduced number of pods plant-1 and seeds pod-1. The 1000 - seed weight, plant height and number of branches plant-1 did not vary much with sowing time. Among the varieties, OUM 11-5 was the high yielder (478 kg / ha) followed by PDM-139 (450 kg / ha) across the sowing dates. 20 January sowing took more number of days to reach flowering, pod initiation and maturity i.e. 38.6 days, 42.5 days and 57.0 days, respectively as compared to crops sown later.
