Optimizing nutrient absorption in basmati rice: A study on drip irrigation and fertigation methods

Abstract

Transplanting rice cultivation is causing a fast depletion of groundwater. The goal of the drip method used nowadays is to produce more rice with less water. India has 143 million hectares of arable land, which presents a huge opportunity for micro irrigation. An environment that is favourable for roots to absorb nutrients and moisture is produced by drip irrigation. It was demonstrated that 100% NPK significantly increased grain absorption when compared to 50% and 75% NPK level. In comparison to the drip method, the flood approach showed lower N, P, and K absorption by rice grains and straw in 2016 and 2017.
