This book was released on 2012-12-06 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The steadily increasing cost of nitrogen fertilizer has resulted in more emphasis on basic and applied studies to improve nitrogen use efficiency in lowland rice. The efficiency of fertilizer nitrogen in farmers' fields is shockingly low ~ a luxury resource-scarce farmers in tropical Asia can ill afford. We believe it is critical to quantify the basic transformation processes and develop management practices for higher N use efficiency for two reasons. They are: 1. Nitrogen fertilizer together with water management is a key factor for achieving the yield potentials of modern rices. 2. Fertilizer nitrogen prices are high and most Asian rice farmers are poor. The International Rice Research Institute (IRRI), Philippines; Internation al Fertilizer Development Center (IFDC), USA; Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia; U.S. Universities (Louisiana, Cornell, California, Arkansas and others); and Dr Justus Leibig University in West Germany are actively engaged in individual or collaborative research that addresses basic transformation processes on N gains and losses and management practices to maximize N use efficiency in rice. It is appropriate to update and summarize, in a double issue of Fertilizer Research, the 10 papers presented at the special symposium organized by the American Society of Agronomy (ASA) at the 75th Annual Meeting in Washington, D.C. in 1983. S.K. De Datta, Head of Agronomy Department, IRRI, was chairman of the International Agronomy Division of ASA (A-6) in 1982 and 1983.

This book was released on 2017 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice (Oryza sativa L.) that is grown in the U.S. is predominantly grown in the mid-south. Current Mississippi State University recommendations for nitrogen (N) fertilization of rice suggest a single application of 168 kg N ha−1 on soils with CEC ≤ 20 and 202 kg N ha−1 on soils with CEC > 20. The primary objective was to identify alternative N management strategies that may potentially be used to reduce costs associated with aerial application of N fertilizer to rice. Research was established at the Delta Research and Extension Center, at Stoneville, MS, on two soil textures during 2015 and 2016. The combination of application timings and N sources resulted in a total of eight N management strategies. Data from all siteyears were pooled together for analysis to evaluate differences among N management strategy. Urea + [N-(nbutyl)thiophosphoric triamide] (NBPT) applied in a single application 7 days before flood (DBF), two-way split application, and PCU-2 LF produced statistically similar and greatest mean rice grain yield. These data suggests that N fertilizer can be applied early (2 to 3 leaf growth stage) from a ground based fertilizer spreader prior to the levee construction. Single optimum and two-way split N management strategies produced more total dry matter (TDM) at heading (HDG) and more N uptake at HDG. Urea + NBPT applied in a single application 7 DBF should be the N management strategy of choice in mid-southern U.S. rice production.
