Key Conclusions
In comparison with the existing Farmer practices, the ICL practice, via the usage of Polysulphate fertilizer, demonstrated a considerable increase in the Bunch weight of the Grapes, size of Berry and the overall Grapes yield per hectare. This translates to additional returns per hectare and also the marginal cost benefit ratio for Grapes crops in Indian conditions
Objective
