摘要

本调查于2021年和2022年哈里夫季节在Shravasti地区的技术农民田间进行。采用随机区组设计,采用对照(T1)、100% RDF (T2)、50% RDF+绿肥(T3)、100% RDF+ Zn (T4)、FYM+绿肥(T5)、FYM+绿肥+Zn (T6) 6个处理。结果表明,100% RDF +Zn处理可提高水稻穗数、亩产、试重、籽粒和秸秆产量。FYM+绿肥+Zn处理对产量和产量性状的改善效果最好。FYM+绿肥+Zn处理土壤pH最大还原量和O.C、N、P、K、S、锌最大有效性也较高。高施氮水平能改善土壤养分状况,有机肥配施效果更明显。

Effect of Integrated Use of Fertilizers, Farm Yard Manure, Green Manure and Zinc on Rice (Oryza sativa L.) Productivity and Soil Fertility
The present investigation was conducted at the technology farmer field of district Shravasti during Kharif seasons 2021 and 2022. The Six treatment viz., control (T1), 100% RDF (T2), 50% RDF+Geen Manure (T3), 100% RDF +Zn (T4), FYM+Green Manure (T5), FYM+ Green Manure +Zn (T6) were replicated in randomized block design in Rice crop variety Rajendra Bhagwati. The data recorded revealed that 100% RDF +Zn increased Number of panicles hill-1, test weight, grain and straw yield. The treatment combination FYM+ Green Manure +Zn was found most effective improving yield and yield attributes. The maximum reduction of pH and maximum availability of O.C, N, P, K, S and zinc in soil was also recorded higher under FYM+ Green Manure +Zn. The nutrients status of soil was improved at higher level of nitrogen and the effect was more noticeable when nitrogen was applied by organic manure.
