Effects of three herbicides on yields of five cultivars of winter wheat (Triticum aestivum L. em Thell)

Creator:: Yahyaoui, Amor
Abstract:: With the development of new selective herbicides and the frequent change in commercial wheat cultivars, information is needed as to the possible interaction between cultivars and herbicides. The responses of five genotypically diverse wheat cultivars (Bezostaya, Daws, Maris Hobbit, Stephens and Yamhill) to diuron [3-(3,4-dichloropheny1)-1,1- dimethylurea], diclofop methyl 2-[4-(2,4-dichlorophenoxy)phenoxy] propanoate...

Effects of irrigation frequency on yields of winter wheat

Creator:: Nakamura, Brian Clifford
Abstract:: Deliberately underirrigating a crop may yield economic benefits. The optimal use of water by an irrigator should be achieved under a deficit irrigation regime. It is important to know how water deficits affect yields and the interaction of the deficits with the scheduling of irrigations. A field experiment was conducted...

Establishment of Kura clover for seed with wheat intercrops

Creator:: Snelling, John P.
Abstract:: Kura clover (Trifolium ambiguum M. Bieb.) is slow to establish and has low seed yields the year after establishment. Intercropping a cereal grain during clover seed field establishment could provide additional revenue to seed growers, provided that intercropping did not jeopardize future clover seed yields. Factorial combinations of spring- and...

Association between length of grain filling period and grain yield in two wheat populations (Triticum aestivum L. em Thell.)

Creator:: Min, Hwang Kee
Abstract:: The objective of this study was to determine interrelationships among agronomic traits in early and late maturing populations. Two populations were obtained from the crosses, Roussalka/Tesopaco 76 and Yamhill/Aspen. Seeds were space planted with split plot design and nine agronomic traits were observed. In comparative studies between early and late...

Nitrogen uptake by wheat (Triticum aestivum VILL., Host) as a function of root temperature and plant water stress

Creator:: Sepaskhah, Ali Reza
Abstract:: The effect of soil temperature and plant water stress on nitrogen uptake, growth rate and transpiration rate of wheat (Triticum aestivum VILL. , Host) seedlings was studied. A special apparatus for the control of plant water stress and root temperature was used. Leaf area was measured by the air flow...

Growth rate and phosphorus uptake of wheat (Triticum aestivum VILL., Host) as a function of soil water suction and soil temperature

Creator:: Fazilat, Mohammad
Abstract:: The effect of soil temperature and soil water suction on the rate of phosphorus uptake and growth rate of wheat (Triticum aestivum VILL. , Host) was studied. Plants were grown in perlite slabs separated from an osmotic solution by a semi-permeable membrane. Measurements were made at temperatures of 10.0, 18.3,...

Sulfhydryl and disulfide changes in young wheat seedlings during vernalization

Creator:: Ellis, Robert William
Abstract:: A study of the SH and SS content levels during vernalization of wheat was made. In order to carry out the study, a rapid analytical technique was worked out which allowed fast sequential analyses of the samples of wheat tissue. Two techniques were used: a) an amperometric titration method and...

Some components of test weight of soft white wheat

Creator:: Shenk, Myron Daniel
Abstract:: Studies of some components of test weight in Soft White wheat revealed distinct subclass differences. Wheat kernels of Soft White more completely occupied a given volume than did kernels of White Club. The Soft White kernels were larger and had a higher density than the White Club kernels. Because of...
