A two-year field experiment was conducted to investigate the effect of leaf colour chart (LCC) and chlorophyll meter (SPAD meter) based nitrogen fertilization on nutrient uptake, use efficiency and productivity of wheat crop under irrigated sub tropics of Jammu. The investigation conducted at Divisional Research Farm of Agronomy, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Main campus Chatha during Rabi 2018-19 and Rabi 2019-20. Experiment was laid out in randomized block design with four replications and six treatments viz. control, nitrogen application based on LCC ≤ 3, nitrogen application based on LCC ≤ 4, nitrogen application based on LCC ≤ 5, sufficiency index based nitrogen application and recommended dose of fertilizer (100:50:25:37.5 kg/ha N:P2O5:K2O:S) along with well fertilized reference plot with 150 per cent recommended dose of nitrogen (150:50:25:37.5 kg/ha N:P2O5:K2O:S) for calculating sufficiency index. Among different treatments of nitrogen management, significantly highest yield and nutrient uptake were recorded with LCC ≤ 5 based nitrogen application. However, sufficiency index based nitrogen application recorded numerically higher nitrogen use efficiency and apparent recovery of nitrogen whereas recommended dose of nitrogen application recorded maximum physiological efficiency.
