Abstract

The present field study was carried out during summer season of 2020 and 2021 at Jaguli Instructional Farm, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal to study the effect of solid and foliar grade of N and K along with trace elements in groundnut (Arachis hypogaea L.). The experiment was laid out in a split-plot design with 3 replications. In main plot; F0, control; F1, 50% RDN and K; F2, 75% RDN and K and; F3, 100% RDN and K and sub-plot T1, Starter dose of N and K @2% with 10:20 ratio + micronutrient mixture of Fe, B, Zn and Mo foliar spray at 30 DAE; T2, Booster dose of N and K @2% with 5:40 ratio + micronutrient mixture of Fe, B, Zn and Mo foliar spray at 45 and 60 DAE; and T3, Starter dose + Booster dose. Growth and yield attributes of groundnut were significantly influenced by application of inorganic fertilizer and maximum were recorded with 100% of RDN and K. Foliar applications of RDN and K with a micronutrient mixture responded better at later stages (45 and 60 DAE) than at an earlier stage (30 DAE). Higher groundnut pod yield was obtained with basal application of 100% of RDN and K but performed statistically same response to the treatment 75% of RDN and K. The pod yield increased by 5–12% with each incremental dose of inorganic fertilizer, while it decreased in control. Booster dose of N and K gave higher pod and oil yield to starter dose. Maximum BCR of 2.38 and 1.99 was found in 100% of RDN and K and in booster doses of N and K. Inorganic fertilizer as basal and foliar application + micronutrients increased the groundnut pod yield but foliar application was not substitute to any quantity of inorganic fertilizer.

不同剂量夏花生基、叶施氮钾及微量元素对夏花生生长的影响
本实地研究于2020年和2021年夏季在西孟加拉邦纳迪亚莫汉布尔Bidhan Chandra Krishi Viswavidyalaya的Jaguli教学农场进行,研究花生(arachhis hypogaea L.)中N和K的固体和叶级以及微量元素的影响。试验采用裂图设计,3个重复。在主要情节;F0、控制;F1, 50% RDN和K;F2, 75% RDN和K;F3, 100% RDN和K和子图T1,启动剂量N和K为2%,比例为10:20 +微量元素Fe, B, Zn和Mo混合叶面喷施,30 DAE;T2, N、K + 5∶40比例+ Fe、B、Zn、Mo混合微量元素叶面喷施45、60 DAE;T3为起始剂量+加强剂量。无机肥对花生的生长和产量性状有显著影响,在100% RDN和K时达到最大值。叶面施用RDN和K与微量元素混合物在后期(45和60 DAE)的响应优于前期(30 DAE)。在基础施用100% RDN和K时,花生的荚果产量较高,但在75% RDN和K处理时,荚果产量在统计学上相同。随着无机肥用量的增加,荚果产量增加5-12%,而对照则下降。N和K的强化剂量比起始剂量的豆荚和油产量高。在100% RDN和K和增加N和K剂量时,BCR最大值分别为2.38和1.99,无机肥作为基施和叶面施用+微量营养素增加了花生的产量,但叶面施用不能替代任何数量的无机肥。
