Abstract:

Rice (Oryza sativa L.) is one of the most important staple food crops worldwide. Nitrogen (N) is the most important nutrient in irrigated rice cultivation. Current high yields of irrigated rice are often associated with applications of higher doses of fertilizer N, as nearly 30-40 percent of applied nitrogen is actually utilized by the crop; even with the best agronomic practices. It has always been a problem to raise the utilization rate of the rice plant and to increase efficiency of absorbed nitrogen for grain production. Hence, a field experiment was conducted during kharif 2017 at the Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G) to study the impact of use of urea briquettes in combination with organics in irrigated rice cultivation system with eleven treatments each replicated four times. Rice variety Rajeshwari was taken as test crop under irrigated condition. The experiment laidout in randomized complete block design comprised of four treatments involving application of urea briquettes, another four treatments involving application of urea and rest three treatments involving application of briquettes of urea + FYM, urea + vermicompost and urea + neem cake as source of nitrogen along with varying doses of phosphorus and potassium. The influence of the different levels and sources of N on nitrogen, phosphorus and potash use efficiency under different treatments were studied. The results revealed that the addition of organics in urea briquettes and deep placement of briquettes exhibited higher nitrogen, phosphorus and potassium use efficiency which might be attributed to slow release of nitrogen, thus reducing the losses and thereby higher nutrients uptake and ultimately higher yield. Nitrogen losses in irrigated rice were significantly influenced by the treatments. The concentration of nitrates and ammonia found in leachates in treatments involving urea+organics briquettes were found significantly lower compared to rest treatments. Application of urea briquettes significantly influenced the available N,P,K in soil at harvest. Overall, urea+FYM briquette application among different sources of fertilizer nitrogen was found most suitable for irrigated rice cultivation system and it also showed higher nitrogen use efficiency as compared to recommended dose of fertilizers.
