An experiment was conducted in the field of instructional cum research farm Indira Gandhi krishi vishwavidalaya Raipur, during kahrif season (2016-2017) with a view to evaluating the effect of rice response and nutrient use efficiency to deep placement of nitrogen and sulphur under submerged condition. The soil of experimental site belong to vertisol. There were seven treatment combinations of sulphur and vermi compost with urea briquette. The treatments include T1 (N0:P0:K0), T2 (N100:P60:K40, N through prilled urea), T3 (N0:P60:K40:S10, sulphur broadcast), T4 (N80:P60:K40, N through urea briquettes), T5 (N80:P60:K40, N through VC briquettes), T6 (N80:P60:K40:S10 N and S through briquettes), T7 (N0:P60:K40) phosphorus + potassium. The experiment was laid out in a randomized block design with three replications. Prilled urea was applied in three equal splits. USG, Urea+ Sulphur briquette and Urea + Vermicompost briquettes were applied in between 7- 10 DAT and the briquettes were placed at 8-10 cm depth between four hills (USG, Urea + Sulphur briquette) and 10X20 cm (Urea + Vermicompost briquette). The yield and yield attributing characters of rice responded significantly superior with T5 (N80:P60:K40, N through VC briquettes) over GRD (N100:P60:K40). The highest grain and straw yield, N content and N uptake was recorded in T5 (N80:P60:K40 N through VC briquettes). The results revealed that the deep placement of urea briquettes accelerated regular flow of N to root may be reason for accumulation of high N in plant tissue and grain, then rice (rajeshwari) yield and yield attribute also increases in rice. Therefore, the application of 80kg N/ha as urea + VC briquettes may be recommend.
