Key Conclusions
In comparison with the existing Farmer practices, the ICL practice, via the usage of Polysulphate fertilizer, demonstrated a considerable increase in the Boll weight of the Cotton crop and the overall seed cotton yield per hectare. This translates to additional returns per hectare and also the marginal cost benefit ratio for Cotton crops in Indian conditions.
Objective
To evaluate the effect of Polysulphate on growth and yield parameters of cotton.
