Abstract

A field investigation was conducted at Central Research Farm of Department of Soil Science and Agricultural Chemistry at Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India during Zaid season of 2023. The experimental plot was laid down into a randomized block design with 9 treatments replicated thrice, consist of 3 levels each of tillage practices and RDF (0 %, 50%, 100%) and 1level of vermicompost (5 t ha -1). Results revealed that maximum bulk density (1.29 Mg m-3) and soil pH (7.10) were found in T1 (Tillage @ 0% + RDF @ 0% +VC @ 5t ha-1). The others soil parameters like porosity (55.60 %),water holding capacity (46.63 %), organic carbon (0.49 %), electrical conductivity(0.25 dS m-1), available Nitrogen (331.54 kg ha-1), available Phosphorus (28 kg ha-1), available Potassium (193.73 kg ha-1 ) were recorded maximum in T9 (Tillage @ 100% + RDF @ 100% +VC @ 5t ha-1) .Whereas best yield (150.56 q ha-1 ) was also recorded in T9 (Tillage @ 100% + RDF @ 100% +VC @ 5t ha-1) .Economic parameters like gross return (₹271008.00 ha-1) and net return (₹152323.00 ha-1) were found to be maximum in T9 (Tillage @ 100% + RDF @ 100% +VC @ 5t ha-1) and best cost benefit ratio (C: B) was recorded as (1:2.28) in treatment T9 (Tillage @ 100% + RDF @ 100% +VC @ 5t ha-1). Integrated approach of application of RDF (NPK), vermicompost along with 100% tillage practices found to be the best treatment as the soil parameters and plant growth parameters significantly affected with the different levels of nutrient and tillage practices.
耕作方式和综合养分管理对印度北方邦豇豆(Vigna unguiculata L. Walp)土壤理化性质和产量的影响
2023 年扎伊德季节,在印度北方邦普拉亚格拉杰的萨姆-希金博顿农业、技术和科学大学土壤科学和农业化学系中央研究农场进行了实地调查。实验小区采用随机区组设计,共设 9 个处理,重复 3 次,包括 3 个耕作方法水平和 RDF(0%、50%、100%)以及 1 个蛭肥水平(5 吨/公顷-1)。结果显示,T1(耕作 @ 0% + RDF @ 0% +VC @ 5t ha-1)的土壤容重(1.29 Mg m-3)和土壤 pH 值(7.10)最大。其他土壤参数如孔隙度(55.60 %)、持水率(46.63 %)、有机碳(0.49 %)、电导率(0.25 dS m-1)、可利用氮(331.54 kg ha-1)、可利用磷(28 kg ha-1)、可利用钾(193.73 kg ha-1)在 T9(耕作率 @ 100 % + RDF @ 100 % +VC @ 5t ha-1)中达到最高值。毛收益(₹271008.00 ha-1)和净收益(₹152323.毛收益(₹271008.00 ha-1)和净收益(₹152323.00 ha-1)等经济指标在 T9 处理(耕作 @ 100% + RDF @ 100% +VC @ 5t ha-1)中最大,最佳成本效益比(C: B)在 T9 处理(耕作 @ 100% + RDF @ 100% +VC @ 5t ha-1)中为(1:2.28)。施用 RDF(氮磷钾)、蛭石堆肥和 100% 耕作的综合方法被认为是最佳处理,因为土壤参数和植物生长参数受到不同养分水平和耕作方法的显著影响。
