Abstract
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%).
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%)。
