abstract
The investigation was carried out on influence of integrated nitrogen management on growth attributes of chickpea (Cicer arietinum L.) Varieties 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 plant height dry matter accumulation crop growth rate (CGR) relative growth rate (RGR) number of nodules plant^- number of branches plant^-1 and SPAD chlorophyll meter reading, statistically at par with GNC 2144 to Of varieties. Among the nitrogen management the integrated application of 50% organic and 50% inorganic sources resulted in the highest plant height dry matter accumulation crop growth rate (CGR) relative growth rate (RGR) number of nodules plant^- number of branches plant^-1 and SPAD chlorophyll meter reading, 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.
