Abstract: A field experiment was conducted at Birsa Agricultural University during winter (Rabi) season of 2017-18 with objective to evaluate the protein content in grain and nitrogen budgeting of soil under precision nitrogen management guided by Green Seeker. The experiment laid out in randomized block design replicated thrice. The soil of experimental plot was sandy loam in texture having low nitrogen (175.6 Kg/ha), medium in phosphorous (15.4 Kg/ha) and potassium (183.5 Kg/ha) with slightly acidic having soil pH 5.5. The twelve treatments comprised of: T1- absolute control, T2 to T4 - application of 120 kg N in two and three split doses, T5 to T7 - application of 150 kg N in two and three split doses, T8 to T10 - application of 180 kg N in two and three split doses and T11 andT12 (guided by Green Seeker by NDVI technique taken at 45 DAS and 65 DAS) were applied with 136 kg N and 140 kg N in three spilt doses respectively. The two splits of nitrogen given at sowing and at CRI and for three splits nitrogen was applied at sowing, CRI and at tillering stage (45 DAS). Application of 140 kg N in three split doses i.e. 30 kg N as basal, 60 kg N at CRI and Greenseeker guided nitrogen application of 40 kg at 45 DAS (second irrigation) and 10 kg at 65 DAS (third irrigation) recorded the highest protein content (11.22%) and maximum utilization of nitrogenous fertilizer in treatments (-2.14 kg/ha and 0.04 kg/ha in T11 and T12 respectively) guided by Greenseeker.
