Abstract
A pot experiment was conducted to see the effect of sodicity and iron levels on cowpea. Four levels of sodium adsorption ratio (SAR) 10, 15, 20, 25 and iron (Fe) control, 5, 10, 15 and 20 kg Fe ha-1) were tested in completely randomized design with three replications. The results indicated that application of soil sodicity having SAR 15 recorded the maximum yield, phosphorus and potassium content and uptake and nitrogen uptake of cowpea over rest of the treatments. Application of Fe 20 kg ha-1 recorded the maximum and significantly higher yield, nitrogen, phosphorus and potassium content and uptake of cowpea over rest of the treatments. Among the treatment combinations combined application of SAR 15 with Fe @ +20 FeSo4.7H2O) proved superior in all these parameters over other treatments.
通过盆栽试验，研究了不同碱度和铁含量对豇豆生长的影响。采用完全随机设计，3个重复，试验4个水平的钠吸附比(SAR)分别为10、15、20、25和铁(Fe)对照(5、10、15和20 kg Fe ha-1)。结果表明，施用sa15土壤碱度的豇豆产量、磷、钾含量、吸收量和氮素吸收量均高于其他处理。施用Fe 20 kg hm -1处理豇豆产量、氮、磷、钾含量和吸收量最高且显著高于其他处理。在处理组合中，SAR 15与Fe @ +20 (FeSo4.7H2O)的联合应用在所有这些参数上都优于其他处理。
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.
