摘要
试验结果表明，不同种植形态和施氮水平对水稻的几乎所有生长性状和产量都有显著影响。植株高度、分蘖数/m2、叶面积指数、干物质积累量/m2随施氮量从0 ~ 180 kg/ha的增加而显著增加。另一方面，种植间距(20cm × 10cm)显著提高了产量(2017年为3.95 t/ha, 2018年为4.65 t/ha)。2017年和2018年分别以20 cm × 10 cm株距和180 kg N/ha处理的籽粒和秸秆产量最高。
Effect of different planting density and nitrogen levels on growth characters and yield of rice (Oryza sativa) grown under eastern Uttar Pradesh
The experimental result revealed that different planting geometry and level of nitrogen had a remarkable influence on almost all the growth characters and yield of rice. Growth characters, viz. plant height, number of tillers/m2, Leaf area index, dry matter accumulation/m2 were increased significantly with the increasing level of nitrogen from 0 to 180 kg/ha in both of year. On the other hand, plant spacing (20cm x 10cm) and produced significantly higher grain yield (3.95 t/ha in 2017 and 4.65 t/ha in 2018). The highest grain and straw yields were recorded with the treatment of 20 cm × 10 cm plant spacing and 180 kg N/ha in 2017 and 2018 respectively.
