TECHNOTUPS: NPKProper nutrient management helps improve crop growth and yield. Oversupply of nutrients from fertilizers may result to crop's increased susceptibility to pests and diseases, and lodging. On the other hand, undersupply of it may result to slow growth of seedlings, low number of tillers, and low grain weight.

Hi Oscar,

It varies depending on various factors such as crop residues, yield of the crop, nutrients in irrigation water, past crop, past fertilizer used and nutrient supplied by the soil. You may ask your nearest Municipal Agriculturist Office for assistance or to your Regional Soils Laboratory for proper diagnosis and nutrient recommendation.
