Abstract:
The present study was conducted to identify the effect of marine gypsum (50% GR), biochar, rhizobium and PGPR on thermal indices of cowpea under saline soils. The cowpea is grown under arid and semi-arid regions of India and is a warm season legume crop. A field experiment was conducted during summer season to determine the effect of different treatments on thermal indices of cowpea at Anbil Dharmalingam Agricultural College and Research Institute, TNAU, Manikandam block, Tiruchirappalli. The treatment T8 with marine gypsum (50% GR), biochar, rhizobium and PGPR recorded higher growing degree days (GDD), photothermal unit and heliothermal unit during 50% flowering, maturity and harvesting stage as compared to other treatments and control.
