Abstract

Manual transplanted rice is labor-intensive, requires a large amount of water, and makes soil poor. Keeping this in view, Non-puddled machine transplanted rice (NPMTR) as an alternative planting technique for puddled machine transplanted rice (PMTR) was tested at Tamil Nadu Rice Research Institute (TRRI), Aduthurai during Kharif seasons 2016 to 2020. The experimental data was analyzed using an independent two-sample t-test. The statistical analysis results indicated that NPMTR and PMTR rice planting techniques did not show any significant difference in rice grain yields and recorded 4.82 and 5.06 t/ha respectively. However, a significant (P < 0.00) higher water use efficiency (4.852 kg/ ha mm) was observed under NPMTR, saving approximately 21% water with a 4.97% yield penalty compared to PMTR. In addition, economic analysis results also indicated a higher benefit-cost ratio (B: C Ratio) of 2.29 under NPMTR than 2.09 in PMTR. NPMTR is cost-effective (less production cost ₹ 5880/ha), resource-saving (fuel 26 L/ ha, energy (1220 MJ/ ha), time (5.5 h/ ha) and water (250.4 mm/ ha), easy to practice and reliable rice transplanting method under fast-changing global climatic conditions.

泰米尔纳德邦Thanjavur地区非水坑机插秧水稻比水坑机插秧水稻的性能

人工插秧是劳动密集型的，需要大量的水，使土壤贫瘠。考虑到这一点，2016年至2020年的哈里夫季节，泰米尔纳德邦水稻研究所（TRRI）在Aduthurai对非水坑机插秧水稻（NPMTR）作为水坑机插秧水稻（PMTR）的替代种植技术进行了测试。实验数据采用独立双样本t检验进行分析。统计分析结果表明，NPMTR和PMTR水稻种植技术对水稻产量无显著影响，分别为4.82和5.06 t/ha。然而，与PMTR相比，NPMTR的水利用效率显著（P < 0.00）更高（4.852 kg/ hm2），节水约21%，产量损失4.97%。此外，经济分析结果也表明，NPMTR的效益成本比（B: C ratio）为2.29，高于PMTR的2.09。NPMTR具有成本效益高（生产成本5880卢比/公顷），节约资源(燃料26升/公顷，能源（1220 MJ/公顷），时间（5.5小时/公顷）和水（250.4毫米/公顷），在快速变化的全球气候条件下易于实践和可靠的水稻移栽方法。
