Assessment of integrated nitrogen management strategies on nutrient content and uptake in chickpea (Cicer arietinum L.) varieties

The investigation was carried out on evaluating the role of integrated nitrogen management on content and uptake of Chickpea (Cicer arietinum L.)varieties a field experiment was conducted at the Instructional Farm, Department of Agronomy, Rajasthan College of Agriculture, MPUAT, Udaipur. Experimental design involved a split-plot arrangement with four chickpea varieties as the main plots and four nitrogen management strategies (100% organic, integrated (50% organic + inorganic), integrated (75% organic + 25% inorganic) and 100% inorganic (recommended dose of fertilizer, RDF) as sub—plots, with three replications. The findings revealed that the chickpea variety GNG 1581 exhibited significantly higher nitrogen, phosphorus, potassium, zinc, iron and copper, statistically at par with GNC 2144 varieties. Among the nitrogen management the integrated application of 50% organic and 50% inorganic sources resulted in the highest nitrogen, phosphorus, potassium, zinc, iron and copper, although it was statistically on par with the 100% inorganic RDF treatment. These results outperformed both the 100% organic and the 75% organic 25% inorganic treatments.
