Nutrient expert assisted site-specific-nutrient-management: An alternative precision fertilization technology for maize production in Chota-nagpur plateau region of Jharkhand

Abstract: A field experiment was conducted during kharif season of 2014 at Birsa Agricultural University, Ranchi, Jharkhand to evaluate the performance of maize hybrids under different nutrient management practices. The experiment was laid out in split plot design with 6 maize hybrids (PMH-1, PMH-3, CMH 08-350, CMH 08-287, CMH 08-292 and HQPM-1) in main plot and 3 nutrient management practices (recommended dose of fertilizer, site specific nutrient management and farmer fertilizer practice) in subplot replicated thrice. Site specific nutrient management exhibited significantly higher cob yield, grain yield, stover yield, which led to significantly higher net return, gross energy output, net energy return over recommended dose of fertilizer and farmer fertilizer practice. The benefit: cost ratio, energy use efficiency, energy productivity with site specific nutrient management was comparable with recommended dose of fertilizer but, significantly higher than farmer fertilizer practice. Significant enhancement in nutrient uptake of nitrogen, phosphorus and potash was also recorded significantly higher under site specific nutrient management than recommended dose of fertilizer and farmer fertilizer practice. Among maize hybrids, CMH 08-350 being comparable to CMH 08-292 produced significantly higher cob yield, grain yield, stover yield, net return, benefit: cost ratio, gross energy output, net energy return, energy use efficiency and energy productivity over other maize hybrids. The maize hybrid CMH 08-350 also removes higher nitrogen, phosphorus and potassium than PMH-1, PMH-3, CMH 08-287 and HQPM-1.
