Abstract
Background: Groundnut kernels contain 48-50% edible oil, 25-34% protein, 10-20% carbohydrates and are a rich source of vitamins (E, K and B complex). Groundnut is a legume-oilseed crop, its requirement of phosphorus, calcium and sulphur is quite high. Gypsum is commonly used as a source of calcium and sulphur for groundnut all over the world. Keeping all these points in view the present study was undertaken to find out the optimum mineral nutrition of spring groundnut Methods: A field experiment was conducted for 2 years at the Students’ Research Farm, Department of Agronomy, Punjab Agricultural University, Ludhiana during spring season of 2018 and 2019. The experiment was laid out in a split plot design replicated three times with four levels of gypsum (0, 125, 175 and 225 kg ha-1) in combination with two gypsum application stages (Full at sowing and 50% at sowing + 50% at flower initiation stage) in the main plot and three levels of nitrogen and phosphorus (15 kg N ha-1 + 20 kg P2O5 ha-1, 25 kg N ha-1 + 30 kg P2O5 ha-1 and 35 kg N ha-1 + 40 kg P2O5 ha-1) in the sub-plot. Result: Application of 225 kg ha-1 gypsum resulted significantly higher growth parameters, pod yield, haulm yield, kernel yield over other gypsum levels. Growth parameters, pod yield, haulm yield and kernel yield were significantly higher with the split application as compared to basal application of gypsum. Growth parameters viz., emergence count, plant height, number of branches plant-1 and dry matter accumulation were increased with increase in the levels of nitrogen and phosphorus up to 25 kg N ha-1 + 30 kg P2O5 ha-1. However, 35 kg N ha-1 + 40 kg P2O5 ha-1 resulted significantly higher protein and oil content of kernels over other levels of nitrogen and phosphorus, while pod yield, haulm yield and kernel yield were at par with 25 kg N ha-1 + 30 kg P2O5 ha-1 during both the years.
背景:花生仁含有48-50%的食用油,25-34%的蛋白质,10-20%的碳水化合物,是维生素(E, K和B复合物)的丰富来源。花生是豆科油料作物,对磷、钙、硫的需要量较高。石膏在世界各地普遍用作花生钙和硫的来源。考虑到所有这些观点,本研究旨在找出春花生的最佳矿物质营养方法:2018年和2019年春季,在旁遮普农业大学农学系学生研究农场进行了为期2年的田间试验。实验是在分裂阴谋设计复制三次四级石膏(0、125、175和225公斤农业的结合两个石膏应用阶段(全在播种,播种50% + 50%在花起始阶段)的主要情节和三个水平的氮和磷(15公斤N农业+ 20公斤P2O5农业,25公斤N农业+ 30公斤P2O5农业和35公斤N农业+ 40公斤P2O5农业的阴谋论调。结果:施用225 kg ha-1石膏显著高于其他石膏水平的生长参数、荚果产量、秸秆产量和籽粒产量。裂施的生长参数、荚果产量、秸秆产量和籽粒产量均显著高于基施。随着氮磷水平的增加,出苗数、株高、分枝数和干物质积累均增加,氮磷水平可达25 kg N ha-1 + 30 kg P2O5 ha-1。而35 kg N hm -1 + 40 kg P2O5 hm -1处理的籽粒蛋白质和油脂含量显著高于其他氮磷处理,籽粒产量、秸秆产量和籽粒产量均与25 kg N hm -1 + 30 kg P2O5 hm -1处理相当。
期刊介绍:
Legume Research An International Journal. The Journal is an official publication of Agricultural Research Communication Centre. It is designed to bring out the original research articles on genetics, breeding, physiology, bacterial avtivity, production, quality, biochemistry and seeds of legumes crops. The objective of the journal is to serve as a forum for scientific community to publish their research findings on legumes ans to provide basis for new research. Journal is being scanned in the important indexing and abstracting services.
