Recent field studies on irrigated rice at the IRRI research farm indicate efficient use of fertilizer-N based on plant uptake of applied N, (estimated by N difference), and utilization of acquired N for increased grain yield. Further increasing the N levels, the N use efficiency was decreased. There is a need to select rice genotypes with high N use efficiency for these specific environments, which was investigated at the Bangladesh Rice Research Institute, Regional Station, Rajshahi, in two successive years. Here, field experiments wer … The purposes of this study were to assess N losses through NH 3 volatilization and surface runoff and to determine the grain yield and N use efficiency (NUE) of early rice in double rice cropping … New solutions are needed to simultaneously increase yield and maximize the NUE of rice. Introduction A marked increase in food production has occurred over the past half-century to feed the growing population, which is mainly attributed to the application of chemical fertilizers ( Godfray et al. Although natural variations of nitrogen transporters have been investigated, key genes associated with assimilation remain largely unexplored for nitrogen use efficiency (NUE) enhancement. Thus, the dep1-1 allele appears to make a contribution to rice yield specifically by increasing nitrogen-use efficiency. Nitrogen use efficiency in crops: lessons from Arabidopsis and rice. Rice is produced under both upland and lowland rice systems, with about 76 % of the global rice produced from irrigated-lowland rice systems. High nitrogen use efficiency of germplasm targeted at rainfed rice-based environments is, together with drought tolerance, of central importance to increase productivity in this agroecosystem. The problem with the increased N application often leads to a reduction in NUE. Introduction. Application of chemical fertilizers, especially nitrogen (N), to crops has increased dramatically in the last half century and therefore developing crop varieties with improved N use efficiency (NUE) is urgent for sustainable agriculture. N utilization procedures generally can be divided into uptake, transport, and assimilation. The importance of the nitrate () transporter for yield and nitrogen‐use efficiency () in rice was previously demonstrated using map‐based cloning. Application of controlled-release urea (CRU) is considered as an effective N fertilizer practice for improving crop yields and NUE. Depending on seasons, higher agronomic N use efficiency (19–30%), physiological N use efficiency (8–18%), partial factor productivity (PFP)N … Nitrogen is an important factor limiting the growth and yield of rice.
