摘要
田间试验于2022年12月在Prayagraj (up) SHUATS农学系作物研究农场进行。试验区土壤呈砂壤土质地，pH值为7.1，为直接中性，有机碳含量低(0.36%)，氮、磷、钾速效度较差(分别为171.48 kg ha-1、15.2 kg ha-1和232.5 kg ha-1)。在为期一年的试验过程中，对包括对照在内的九种治疗方法进行了评估。每一个都被复制了三次。结果表明，施用氮磷钾120:60:60 kga -1 + 25 × 10 cm可显著提高水稻株高(105.00 cm)、分蘖数(18.90)、植株干重(38.99 g/株)、穗丘数(14.00)、粒数/穗数(195.00)、试重(18.32g)、穗长(30.11)、籽粒产量(5.96 t ha-1)、秸秆产量(11.12 t ha-1)和收获指数(44.67%)。
Effect of Nitrogen, Phosphorous, Potassium (NPK) Levels and Spacing on Growth and Yield of Rice (Oryza sativa L.)
The field experiment was conducted in Khairf 2022 at the Crop Research Farm of the Department of Agronomy, SHUATS, Prayagraj (U.P.). A sandy loam texture, a pH of 7.1 that was directly neutral, a low quantity of organic carbon (0.36%), and poor availability of the nutrients n, p, and k (171.48 kg ha-1, 15.2 kg ha-1, and 232.5 kg ha-1 respectively) were every feature of the soil in the experimental plot. Over the course of a one-year trial, nine treatments including a control were evaluated. Each was reproduced three times. The findings proved that application of NPK 120:60:60 Kgha-1 + 25 × 10 cm was recorded significantly higher plant height (105.00 cm), Number of tillers/plant (18.90), Plant dry weight (38.99 g/plant), Panicles/hills (14.00), grains/Panicle (195.00), Test weight (18.32g), Panicle length (30.11), Grain yield (5.96 t ha-1), Straw yield (11.12 t ha-1), Harvest index (44.67%).
