Potential for nitrogen fertilization and Hessian fly-resistance to improve Morocco's dryland wheat yields
Autor: John Ryan, M. Abdel Monem, J. P. Shroyer, M. El Bouhssini, M. M. Nachit
Publikováno v: European Journal of Agronomy. 8:153-159
Hessian fly ( Mayetiola destructor , Say) is a perennial scourge of cereal production in the Mediterranean region, particularly in North Africa. In Morocco, it accounts for considerable yield losses of wheat ( Triticum spp. ), especially in the semi-

Autor: J. P. Shroyer, W. F. Heer, R. L. Bowden, W. W. Bockus, M. M. Claassen, W. B. Gordon
Publikováno v: Canadian Journal of Plant Science. 77:567-572
Two field experiments were established to compare four times of fungicide application (flag leaf emergence, boot, fully headed, and milky ripe) for improving production of large seed. Quadratic models fit the data when large-seed (≥0.238-cm diamete

Productivity and adaptive capacity of winter wheat landraces and modern cultivars grown under low-fertility conditions
Autor: T. S. Cox, J. P. Shroyer
Publikováno v: Euphytica. 70:27-33
In recent decades, most winter wheat (Triticum aestivum L.) breeding in the United States has been done in field nurseries in which the soil receives ample fertilization. To determine the effects of these breeding efforts on productivity under low-fe

Relay Intercropping Soybeans into Wheat in Kansas
Autor: J. P. Shroyer, W. T. Schapaugh, S. R. Duncan
Publikováno v: Journal of Production Agriculture. 3:576-581
Research was conducted to evaluate relay intercropping of soybeans [Glycine max (L.) Merr.] into winter wheat (Triticum aestivum L.) in areas of Kansas where length of growing season and inadequate rainfall limit the productivity of doublecropped soy

Production of fall-planted cereals in Morocco and technology for its improvement
Autor: J. Ryan, J. P. Shroyer, M. Abdel Monem, M. El Mourid
Publikováno v: Journal of Agronomic Education. 19:32-40
Cereal production is of paramount importance in the national economies of Middle East-North African countries. High per capita consumption of cereal products along with rapid population growth underlies endeavors to achieve self-sufficiency. The purp

The impact of reduced tillage on soilborne plant pathogens
Autor: W. W. Bockus, J. P. Shroyer
Publikováno v: Annual review of phytopathology. 36
▪ Abstract Farmers increasingly leave crop residues on the soil surface rather than incorporating them into the soil. This practice helps reduce soil erosion, conserve energy, increase soil moisture, and increase crop yields. However, many soilborn
