Abstract HM 4 plant population level of 83,333 plants/ha and the nutrient level of N187.5P32.75K62.5 recorded more baby corn yields with and without husk and green fodder yield. HM 4 also noticed more brix value than PEHM 2. Reduction in cob protein was noticed with increase in plant population from 66,666 to 83,333 plants/ha. Increasing plant population from 66,666 to 83,333 plants/ha considerably reduced available N, P and K contents in soil. However, contents of all these nutrients improved with each increase in nutrient levels from control to the highest dose of NPK. N, P and K uptake in baby corn and fodder was found maximum with application of N187 5P32.75K62 5kg/ha. The net returns remained more with HM 4 and 83,333 plants/ha. There was substantial improvement in net returns with each increase in nutrient levels. Top Keywords Baby corn, HM 4, PEHM 2, Returns, Soil fertility, Yield. Top |
