Download or read book The Effect of Row Spacing Rate and Date of Planting on Yield and Yield Components of Four Winter Wheat Cultivars Triticum Aestivum L Em Thell written by Benacef Nadjib and published by . 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.

Available in PDF, EPUB and Kindle. Book excerpt: By the year 2050, the world's population is expected to reach nine billion. To feed and sustain this projected population, world food production must increase by at least 50 percent on much of the same land that we farm today. To meet this staggering challenge, scientists must develop the technology required to achieve an "evergreen" revolution-one

Download or read book Effect of Row Spacings Seeding Rates and Nitrogen Fertilizer Rates on the Agronomic Performance of Yamhill and Hysolop Wheat Triticum Aestivum L written by Mohamed Chemli and published by . This book was released on 1972 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The response of two newly released cultivars of winter wheat when grown under different row spacings, seeding rates and nitrogen levels were investigated. Measurements made included grain yield, tiller number per unit area, plant height, 300 kernel weight, bushel weight and protein content of the grain. Hyslop and Yamhill cultivars were selected since they represent different plant types and may respond differently to various cultural practices. Results indicated that optimum grain yield under the growing conditions of this study was obtained with 15. 24 cm row spacing and 134. 5 kg/ha seeding rate. Also at the 15. 24 cm row spacing, 112 kg/ha of nitrogen gave the greatest yield response. This was true for both cultivars tested. More culms per square meter were produced by the 15.24 cm row spacing. The largest number of culms being attained with 15. 24 cm spacing and 134.5 kg/ha seeding rates with both cultivars responding in a similar pattern. The plant height for both Hyslop and Yamhill remained the same at all row spacings; however the higher seeding rates resulted in increased plant height. Yamhill had a higher 300 kernel weight and a lower bushel weight than Hyslop regardless of the treatments. Different row spacings did not influence either 300 kernel weight or the bushel weight. Increased seeding rates did result in a variable 300 kernel weight and in a higher bushel weight for both cultivars. Protein content of the grain was not affected by either row spacing or seeding rates, but was influenced by nitrogen application. With the exception of the first 56 kg/ha nitrogen application, the other additional applications of nitrogen resulted in an increased protein content. Despite different growing patterns, both Hyslop and Yamhill responded similarly to the cultural practices imposed. It would appear that maximum grain yield, under the growing conditions observed in this study can be obtained by increasing the number of spikes per unit area. This could be achieved by using 15. 24 cm row spacing and 134.5 kg/ha as a seeding rate with 112 kg/ha of nitrogen. A mean of disseminating such information to the growers was also considered in this study.
