Evaluation of Growth and Yield Parameters of Rice under Different Cultivation Methods

Background: Water is the most important environmental factor for sustainability of rice production. Traditionally rice was cultivated by continuous flooding. Due to global climate change and rapid industrialization and urbanization, the amount of water utilised for agriculture is declining which increases the water scarcity for irrigated rice production. Methods: The present experiment was carried out during Kuruvai (July-November) 2022 at 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: Results of the experiment showed that growth parameters was higher in SRI method and this was on par with conventinal method. SRI method recorded significantly higher yield parameters and grain yield. From the above results, it can be concluded that. SRI method performed well compared to different method of cultivation due to the synergistic effects of various cultivation principles followed in this method.
