Abstract

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.

不同栽培方式下水稻生长及产量参数的评价

背景:水是水稻生产可持续性最重要的环境因素。传统上，水稻是在连续的洪水中种植的。由于全球气候变化和快速的工业化和城市化，农业用水量正在下降，这增加了灌溉水稻生产的水资源短缺。方法:本实验于2022年7 - 11月在哥印拜陀泰米尔纳德邦农业大学进行。试验采用T1 ~ 100%滴灌饱和、T2 ~ 150%滴灌饱和、T3 ~ 200%滴灌饱和、T4 ~水稻强化体系(SRI)、T5 ~常规方法5个处理。结果:实验结果表明，SRI方法的生长参数较高，与常规方法相当。SRI方法的产量参数和籽粒产量显著提高。从以上结果可以得出。由于SRI方法所遵循的各种栽培原则的协同效应，使得该方法与其他栽培方法相比表现良好。
