Book excerpt: Many farmers typically regard wheat as a “low input” crop and expect low yields and low returns. Conversely, some farmers intensively manage wheat with many inputs and expect high yields and returns. The objective of this research was to identify inputs that improve wheat grain yield, straw yield, and economic return and reduce deoxynivalenol (DON) concentration in the grain. An incomplete factorial, omission trial was established at two locations in Ohio (South Charleston and Custar) during the 2019-2020 and 2020-2021 growing seasons. Treatments consisted of intensive management (IM) which received all inputs, a traditional management (TM), and the individual addition or removal each input from the TM or IM, respectively. The inputs were a high seeding rate, a high N rate, a split application of N, a spring sulfur application, a fungicide application at Feekes 9, and a fungicide application at Feekes 10.5.1. Intensive management increased grain yield at three of the site-years during this study by an average of 0.83 Mg ha-1. At the South Charleston location, in general, the use of a fungicide at either timing proved to be important for protecting yield. The addition of a fungicide at Feekes 10.5.1 to the TM significantly protected yield both years by an average of 0.66 Mg ha-1 and the removal of this fungicide from the IM significantly decreased yield by 0.63 Mg ha-1 in 2021. Additionally, at the same location the addition of a fungicide at Feekes 9 to the TM and the removal of a fungicide from the IM significantly changed yield in 2020 by 0.81 and -0.71 Mg ha-1. At Custar, only one treatment significantly changed yield in either year. In 2021, the removal of split N from the IM significantly reduced grain yield by 0.44 Mg ha-1. Straw yield was not consistently affected by any treatment in this study. DON concentration was significantly reduced by the IM at South Charleston both years due to the addition of a fungicide at Feekes 10.5.1. Intensive management did not increase partial economic returns at any site-year during this study and individual treatment affects were inconsistent. These results suggest that although IM has can improve grain yield and quality it fails to do so economically at the prices used in this study.

This book was released on 1990 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: A negative relation between grain protein content and grain yield is frequently observed in wheat (Triticum aestivum L. em Thell) i.e. as grain yield increases, grain protein decreases. It has been suggested that the inverse relation between grain yield and protein is in part the result of developing high yielding semi-dwarf wheat cultivars with an increased harvest index. This investigation was undertaken to determine the nature of the possible association of grain yield and protein content as influenced by harvest index, biological yield, plant height and kernel weight in winter wheat populations grown in Oregon. Progenies derived from three crosses of winter wheat were solid-planted in two environments during two seasons. Phenotypic correlations showed a moderate negative association of grain protein content with both grain yield and harvest index. The magnitude of the genetic correlations suggested the presence of genetic relationships among these traits. Selection for harvest index among these crosses could cause a correlated reduction of grain protein content. To investigate if the relationships between grain protein content and selected plant growth traits were similar when grown under space-planted and solid seeded stands, progenies of two winter wheat crosses were evaluated during two seasons. Performance for grain yield and grain protein content was different under contrasting sowing densities as values were not correlated between sowing densities. This indicates the need to evaluate these traits in solid-seeded stands. Harvest index, as well as plant height and heading date, could be effectively selected under space-planted or solid seeded conditions. Associations among traits were reliably estimated in space-planted stands. To evaluate the effect on grain protein content when grain yield and harvest index are modified, the plant growth regulator Paclobutrazol was applied to selected winter wheat genotypes under field and greenhouse conditions. Paclobutrazol increased grain yield and harvest index values of all genotypes in the greenhouse, while only some genotypes improved these traits under field conditions. Grain protein content, however, remained unchanged. Higher grain yields were obtained in both greenhouse and field experiments.

Book excerpt: High protein wheat seeds frequently perform better than low protein seeds of the same variety. Protein content of seeds can be increased by management practices, the most important of which is rate and timing of N applications. The purpose of this study was to determine the chemical, biochemical and physiological changes that occur in seeds as a result of nitrogen fertilization, and to relate these changes to seed performance. Seeds of Yamhill, Paha and Hyslop soft white winter wheat were produced with N applications of 0 to 450 kg/ha. Applications were made at planting, flower initiation, and anthesis. Supplemental irrigation was supplied. Applications of 150 and 300 kg N /ha increased the grain yield and protein yield per hectare, seed size, and percent and amount of protein per seed of Yamhill wheat. N applications caused several biochemical changes in the food reserve of the seeds. These included increases in the amounts of gluten, each amino acid studied and free amino acids. The amount of soluble sugars decreased slightly and starch remained constant with high rates of N.N also caused several biochemical changes in embryos. These included increases in: free amino acids and soluble sugars; protein concentrations and amount per embryo; ADP, ATP and energy charge. Regardless of protein concentration, the quantities of solubles and adenylate phosphates were higher in larger embryos. Biochemical changes in seedlings associated with N applications and higher protein content included: more sugars and free amino acids; higher amounts of ATP, ADP and total AP; and faster rate and higher net translocation of food reserves. Small seeds contained a higher concentration of ash, some mineral elements, soluble sugars and free amino acids. The total amount of these compounds per seed, however, was related to protein content and seed size. The large seeds with high protein concentration produced seedlings with the highest ADP, ATP and total AP content, energy charge and growth potential. Smaller seeds absorbed water and germinated faster than larger seeds. Seedlings from small seeds produced longer roots and shoots during the early stages of growth, but their growth rate was slower at later stages. High protein seeds of Hyslop, Paha and Yamhill outyielded low protein seeds by 12 to 17%. Yield differences were obtained when N was added to the crop, but not in the absence of added N. These and other studies indicate the potential for improving wheat seed and quality by applying specialized management practices for seed production rather than managing for grain production.

This book was released on 1986 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Take-all root rot (caused by Gaeumannomyces graminis var. tritici, Ggt) is one of the major diseases limiting winter wheat yields in western Oregon. Losses caused by take-all (TA) can be significantly reduced through crop management and fertilization practices. Results from field experiments in western Oregon show that the use of chloride with NH4-N is an effective tool to minimize grain yield losses in fields with TA. This study was undertaken to determine the effects of fall- and spring-applied chloride fertilizers on the components of leaf water potential, grain yield and disease severity of winter wheat with TA. Winter wheat field plots were established on a Woodburn soil (Aquultic Argixeroll) on 15 October 1980 at a site previously cropped to first-year wheat after fallow. Spring fertilizer application was on 16 March 1981. Twenty treatments were arranged in a randomized complete block design to study the effects of source, rate, method of application and timing of chloride fertilizers on grain yield, disease severity and leaf water potential components. Other comparisons included rates of P and Cu plus Zn banded in the fall, and fall and spring nitrogen rates. Grain was harvested with a plot combine on 30 July 1981, and grain yield, test weight and 1000 kernel weight were measured. Disease severity was assessed using two methods, (1) visual estimation of black root lesions on three dates, and (2) whole plant fresh weights on 2 July 1981. Leaf osmotic potentials and plant nutrient concentration were measured on four dates. Leaf water potential components (turgor, osmotic and leaf water potentials) and plant nutrient concentrations were determined during May and June on second-year wheat and once on third-year wheat from an adjacent site. A partial diurnal water curve for (NH4)2S04- and NH4Cl-treated plants was measured on 2 June 1981, on third-year wheat. Grain yields were increased by 1000 kg/ha with the addition of spring chloride as NH4CI, KCl or CaCl2. Arate of 92 kg spring Cl/ha was adequate to achieve the highest grain yield (6633 kg/ha). Grain yield was not significantly affected by rate, source or method of application of fall-applied chloride, fall or spring N rates, or by the application of P or Cu plus Zn banded with the seed at planting. Application of 368 kg spring Cl/ha as NH4Cl reduced severity of take-all and increased whole-plant fresh weight when compared to (NH4)2S04 at the same rate of N, but the differences were not statistically significant. Disease severity was not significantly affected by either rates or sources of spring chloride. Grain yields were negatively correlated to disease severity indices. Spring chloride fertilizers applied as NH4Cl or KCl significantly increased percent total N in flag leaves sampled in late spring, while the percent leaf chloride was increased with application of either KCl, NH4C1 or CaCl2. Osmotic potentials in flag leaves of second-year wheat were significantly reduced (from -21.6 to -22.6 bars) over the nil CI rate by application of spring chloride fertilizers. Ninety-two kg Cl/ha was adequate to reduce the osmotic potential. Spring chloride at 368 kg Cl/ha significantly increased turgor potentials in both secondand third-year winter wheat, and significantly decreased osmotic potentials (2 bars) in second-year wheat when compared to (NH4)2S04- treated plots at the same N rate. Potassium chloride significantly reduced leaf and osmotic potentials at the 185 kg Cl/ha rate. Potassium chloride did not increase turgor. The results of this study support the recent literature indicating that application of spring chloride in combination with ammonium-nitrogen to moderately acidic soils reduces the severity of take-all and increases yield of winter wheat.
