MAXIMIZING YIELD AND NET RETURNS TO NITROGEN, PHOSPHORUS AND POTASSIUM FERTILIZER APPLICATION IN RICE (Oryza sativa. L) PRODUCTION ON LOWLAND SOILS

Current fertilizer recommendations for rice do not commonly consider fertilizer cost relative to paddy price (CP). The rates needed for maximizing yield rather than profits have been rather estimated.
