Book excerpt: Critical nutrient percentage is defined as the nutrient concentration associated with maximum yield with respect to the nutrient. Objectives of this research were: (1) to compare three methods for calculating maximum yield and associated critical % N and to determine effects of time of leaf sampling at or near silking on critical % N; (2) to determine effects of P fertilizer rates on critical % N and of N rates on critical % P; and (3) to determine effects of crop sequence, plant density, and moisture stress on critical % N and % P in both grain and leaf. Data were from 39 fertilizer experiments at 4 outlying research centers in Iowa. The direct regression method (Yield on % N in the plant part) was generally poorer for estimating critical % N in the grain and leaf than the two-step method (yield and % N on N rates) or graphical method (highest yield based on significance and associated % N). The latter two were similar. Time of leaf sampling and weather factors prior to and during silking affected % N of treatments and critical % N. The P rates increased critical % N in grain as mich as 0,12% and that leaf as much as 0.16%. As N rates increased, critical % P decreased as much as 0.028% in the grain and increased as much as 0.58% in the leaf. The critical % N and % P in the grain of leaf can evaluate N and P fertility status of corn better if levels of both are considered. The critical % N and % P in both grain and leaf were slightly less in C2 than in C1 in a C1-C2-soybean roatation. Increased stand level (...).

Book Synopsis Principles of Seed Science and Technology by : Lawrence O. Copeland
Download or read book Principles of Seed Science and Technology written by Lawrence O. Copeland and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Fourth Edition of Principles of Seed Science and Technology, like the fIrst three editions, is written for the advanced undergraduate student or lay person who desires an introduction to the science and technology of seeds. The fIrst nine chapters present the seed as a biological system and cover its origin, development, composition, function (and sometimes nonfunction), performance and ultimate deterioration. The last nine chapters present the fundamentals of how seeds are produced, conditioned, evaluated and distributed in our modern agricultural society. Two new chapters have been added in this fourth edition, one on seed ecology and the second on seed drying. Finally, revisions have been made throughout to reflect changes that have occurred in the seed industry since publication of the Third Edition. Because of the fundamental importance of seeds to both agriculture and to all of society, we have taken great care to present the science and technology of seeds with the respect and feeling this study deserves. We hope that this feeling will be communicated to our readers. Furthermore, we have attempted to present information in a straight-forward, easy-ta-read manner that will be easily understood by students and lay persons alike. Special care has been taken to address both current state-of-the-art as well as future trends in seed technology.

Book Synopsis Maize Agroecosystem by : K. R. Krishna
Download or read book Maize Agroecosystem written by K. R. Krishna and published by CRC Press. This book was released on 2012-07-19 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize is among the most widely spread and widely used crops of the world, used for cereals for over 4 billion humans, as food for farm animals, and as a source material for biofuel production. Yet there are relatively few books on the cropping system of this important crop. This book, Maize Agroecosystem, is a concise treatise dealing with agronomy, soil fertility, and productivity of maize. The information is global in nature and considers recent developments in all maize cropping belts. The "global maize agroecosystem" is a conglomerate of several "maize cropping belts" that flourish on different continents. The impact of nutrient management on the productivity of maize agroecosystems is the main focus of this book. The book includes the history of maize growing, the kinds of soil needed, nutrient dynamics, the use of soil organic matter, the physiology and genetics of maize, and integrated nutrient management. It presents comprehensive knowledge regarding the physicochemical dynamics of the three major nutrients: nitrogen, phosphorus, and potassium. Also covered is how fertilizers impinge on soils of maize farms and their impact on soil and groundwater quality. The impact of crop genotype on soil nutrient dynamics and productivity is also highlighted. The information provided here will be highly useful to students at colleges and universities in the fields of agricultural sciences and environmental science and ecology, and the book also functions as valuable resource for researchers and professors in crop science. Several figures and tables are included that describe and summarize the impact of various agronomic/fertilizer management procedures on crop productivity.
