This book was released on 1982 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four winter wheat cultivars, Bezostaya, Maris-Hobbit, Roussalka and Stephens, selected on the basis of the diversity of their pedigree and phenotype, were planted at Hyslop Experiment Station near Corvallis in Western Oregon to study their performance at three different row spacings (10, 16 and 24 cm), three seeding rates (100, 160, and 240 Kg/ha) and at two seeding dates (October 13 and November 12). A similar experiment was conducted at the Sherman Experiment Station, Moro in Eastern Oregon, using only two winter wheat cultivars, Stephens and Jackmar. Data were obtained on grain yield, tillers and spikes per square meter, heading and anthesis date, plant height, kernels per spike, 1000 kernel weight, test weight and harvest index. At Hyslop Experiment Station, Stephens, Bezostaya and Roussalka produced maximum grain yield at 10 cm row spacing and 160 Kg/ha seeding rate, and Maris-Hobbit at 24 cm row spacing and 160 Kg/ha seeding rate. At Sherman Experiment Station, 30 cm row spacing and 90 Kg/ha seeding rate constitutes the best combination for Stephens, and 30 cm row spacing and 120 Kg/ha seeding rate for the club wheat Jackmar. The interaction between row spacings x cultivars and seeding rates x cultivars indicated that all the cultivars produced high numbers of tillers and spikes per m2 at narrow (10 cm) row spacing and high (240 Kg/ha) seeding rate. There were no significant differences between row spacings for heading and anthesis date. Lower seeding rate resulted in later heading date. The cultivar Roussalka was the earliest and Maris-Hobbit the latest in average heading date, Plant height decreased with increased row spacing and increased with increased seeding rate. The plants of the four cultivars were shorter at the second date than at the first. More kernels per spike were produced at the second than at the first date. An increase in seeding rates was accompanied by a decrease in the number of kernels per spike. There were no significant differences between the three row spacings, the three seeding rates and the four cultivars for test weight. The different row spacings and seeding rates did not affect the TOGO kernel weight. Considering the cultivars, Stephens produced a higher 1000 kernel weight at the two seeding dates than Maris- Hobbit, Bezostaya and Roussalka.

Download or read book Yield and Other Agronomic Characters of Winter Wheat Cultivars as Affected by Five Seeding Rates and Three Different Environmental Conditions written by Mengü Güler and published by . This book was released on 1974 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five newly released and two Eastern European winter wheat cultivars were grown under five different seeding rates (80, 160, 240, 320, 400 seeds per m2). Four of these newly released cultivars were grown at three different locations which have different environmental conditions. Data were obtained on grain yield, tiller number per plant, 1000 kernel weight, seed number per spike, plant and spike number per unit area, plant height, heading and maturity dates. At the lowest rate of seeding the grain yield was significantly lower at all three locations. Although there were no significant differences for grain yield for all the other seeding rates, maximum yields were obtained from lower seeding rates at Ryan while at Hyslop and Madras, which had better moisture conditions, maximum yields were obtained at higher seeding rates. This situation was not observed for the Yamhill cultivar in which maximum yields were obtained at 160 seeds per m2 seeding rate at all three locations. Tillers per plant value decreased as the seeding rate increased. Hyslop and McDermid produced significantly higher number of tillers per plant from the other cultivars. Significantly highest 1000 kernel weight values were obtained at the lowest seeding rate. Yamhill produced the highest significant 1000 kernel weight while Paha produced the lowest. Seeds per spike value followed the same order as tillers per plant and 1000 kernel weight showing a continuous decrease with the increased rates of seeding. The number of plants per m2 was a direct linear function of seeding rate. The number of spikes per m2 increased curvilinearly with the increased seeding rate. Hyslop and McDermid produced the highest significant number of spikes per m2 because of their higher tillering ability. Plant height increased with increased rates of seeding because of the increased competition for light. Yamhill and Paha were significantly the tallest cultivars. The tallest plants were observed at Hyslop. There was a decrease in the number of days in heading and maturity as the rates of seeding increased. The cultivars ranked in the order Paha> Yamhill> Hyslop> McDermid for heading and maturity dates. Heading first occurred at Hyslop followed by Ryan and Madras while maturity occurred first at Ryan followed by Hyslop and Madras. Highly positive correlations were observed among plants per m2, spikes per m and seeding rate while these factors correlated negatively with tillers per plant, 1000 kernel weight and seeds per spike. The regression equations showed that maturity date, heading date and spikes per m2 values were the most important factors for predicting yield.

This book was released on 2001-12-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture. Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population. Strategies and perspectives are considered to improve nitrogen-use efficiency. Issues of nitrogen in crop and human nutrition, and transport and transformations along the continuum from farm field to ground water, watersheds, streams, rivers, and coastal marine environments are discussed. Described are aerial transport of nitrogen from livestock and agricultural systems and the potential for deposition and impacts. The current status of nitrogen in the environment in selected terrestrial and coastal environments and crop and forest ecosystems and development of emerging technologies to minimize nitrogen impacts on the environment are addressed. The nitrogen cycle provides a framework for assessing broad scale or even global strategies to improve nitrogen use efficiency. Growing human populations are the driving force that requires increased nitrogen inputs. These increasing inputs into the food-production system directly result in increased livestock and human-excretory nitrogen contribution into the environment. The scope of this book is diverse, covering a range of topics and issues from furthering our understanding of nitrogen in the environment to policy considerations at both farm and national scales.
