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.

This book was released on 2012-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Download or read book Effect of Row Spacing on Wheat Yield written by Muhammad Abu Bakar Zia and published by LAP Lambert Academic Publishing. This book was released on 2014-10-09 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study is the research work of my M.Sc. which titled "optimizing row spacing in different wheat cultivars" was conducted at Agronomic Research Farm, Department of Agronomy, Faculty of Agricultural sciences and technologies, Bahauddin Zakariya University, Multan. Three row spacings viz. 10, 20 and 30 cm and five wheat genotypes viz. Sehar-2006, FS-2008, Lasani-2008, AS-2002 and TD-I were included in the study. The experiment was laid out in randomized complete block design (RCBD) with split plot arrangements having net plot size of 5 m x 1.8 m and replicated three times. Row spacings were kept in main plots while wheat genotypes were kept in sub plots.

Download or read book Evaluating Seeding Rate and Cultivar Impact on Grain Yield and End use Quality and Finding Replacement Methods to Assess Spring Stands of Soft Red Winter Wheat Triticum Aestivum L in Ohio written by Allen W. Goodwin and published by . This book was released on 2017 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differences between area of land planted to wheat and area harvested indicate that poor wheat stands are being destroyed in the spring to plant more profitable crops. Current recommendations to evaluate spring stands are stem counts at Feekes growth stage (GS) 5, a practice that is not implemented by producers due to time and labor involved. Two promising replacement measurements are the normalized difference vegetation index (NDVI) and fractional green canopy cover (FGCC). An experiment was conducted consisting of four site-years at two on-farm locations in Pickaway and Crawford Counties during the 2015/2016 and 2016/2017 growing seasons. The design was a randomized complete block design with five seeding rates as the treatment. The objectives were to determine if FGCC was correlated to tiller counts, and to quantify the difference in yield prediction accuracy of tiller counts, NDVI, and FGCC (30.5 cm section of row called “1-row” and 3-row area) at Feekes GS 5 and 6, and head counts at Feekes GS 10.5. Linear regression models fit for stem counts at Feekes GS 5 and 6 vs. FGCC for 1-row at Feekes 5 and 6, respectively, were significant and were able to estimate stem density. The best estimators of yield were NDVI and 3-row FGCC measurements taken at Feekes GS 5, and can be used to estimate the proportion of yield that will result from a spring stand. Producers may adopt the stem estimation methods when making a decision about wheat stands in the spring and consider using NDVI and FGCC for yield estimation.
