TAILIEUCHUNG - Precision nutrient management in wheat using nutrient expert

Nutrient management has played a main role in achieving self-sufficiency in food grain production. A field experiment was conducted during Rabi 2016-17 and 2017-18 to evaluate nutrient requirement of wheat using Nutrient Expert Model (NE is a simple computer based decision support system or delivery tool developed by IPNI [International Plant Nutrition Institute] that can rapidly provide nutrient recommendations for N, P and K for crops). The experiment was conducted in Randomized Block Design replicated thrice at Wheat and Barley Research area, CCS HAU, Hisar, Haryana. Seven treatments executed were absolute control (without NPK), Recommended dose of fertilizer (RDF; 150 kg N/ha, 60 kg P2O5/ha and 40 kg K2O/ha), 150% RDF, 150% PK, 150% NK, 150% NP and compared with NE (Nutrient Expert Recommendation).Based on pooled two years data 2016-17 and 2017-18, experiment revealed that the highest grain yield ( q/ha) was recorded when 150% recommended dose of fertiliser was applied which was significantly higher than other treatments except when fertiliser was applied on the basis of nutrient expert model ( q/ha). | EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 02 2019 Journal homepage http Original Research Article https Precision Nutrient Management in Wheat using Nutrient Expert Mukesh Kumar and Bhagat Singh Department of Agronomy CCS Haryana Agricultural University Hisar Haryana 125004 India Corresponding author ABSTRACT Keywords Wheat Nutrient Expert RDF and grain yield Article Info Accepted 18 January 2019 Available Online 10 February 2019 Nutrient management has played a main role in achieving self-sufficiency in food grain production.

The experiment was conducted in Randomized Block Design replicated thrice at Wheat and Barley Research area CCS HAU Hisar Haryana. Seven treatments executed were absolute control without NPK Recommended dose of fertilizer RDF 150 kg N ha 60 kg P2Os ha and 40 kg KO ha 150 RDF 150 PK 150 NK 150 NP and compared with NE Nutrient Expert Recommendation .Based on pooled two years data 2016-17 and 2017-18 experiment revealed that the highest grain yield q ha was recorded when 150 recommended dose of fertiliser was applied which was significantly higher than other treatments except when fertiliser was applied on the basis of nutrient expert model q ha . Similarly the maximum biological yield q ha was obtained from 150 RDF followed by NE q ha . Minimum grain and biological yield was recorded from absolute control treatment which was without fertilizer application. Maximum number of effective tillers m2 428 and plant height cm were also recorded when 150 .
