Abstract
Background: The plant roots pay a vital role in the uptake of water and nutrients. This experiment evaluated the changes in root growth and soil enzyme activity with respect to different rice cultivation methods. Methods: The study was carried out during Kuruvai (July-November) 2022 at Wetlands farm, Tamil Nadu Agricultural University, Coimbatore. Experiments were carried out with five treatments viz., T1- 100% Saturation under drip irrigation, T2- 150% Saturation under drip irrigation T3- 200% Saturation under drip irrigation, T4- System of Rice Intensification (SRI), T5- Conventional method. Result: The result of the experiment shows that higher root growth, enzyme activity was observed in SRI method of rice cultivation. Higher grain yields were recorded in SRI method. It can be concluded that most favourable method of rice production.
