Wheat is the major crop produced on the Anatolian Plateau of Turkey. Annual weeds cause large yields reductions in the wheat crop. Several formulations of 2, 4-D and mixtures of 2, 4-D and 2,4, 5-T are the only materials currently available for use in Turkey on wheat. The objective of this study was to determine the optimum time for application of herbicides in order to reduce competition between winter wheat (Triticum aestivum cv. 'Bolal') and annual weeds. Several herbicides and herbicide mixtures were compared for their effectiveness against two major weed species, yellowweed (Boreava orientalis L.) and cornflower (Centaurea cyanus L.). Herbicides were applied at three different dates according to growth stages of wheat and weeds. Two series of handweeded plots were also included. One set allowed weed competition with the wheat for 4 and 8 weeks and was handweeded for the remainder of the season. The other set was kept free of weeds for 4 and 8 weeks and left weedy for the remainder of the season. Weed-free and weedy control plots were included. Wheat which was free from weed competition in the early part of the growing season produced the highest yields. Plots on which herbicides were applied at the earliest date produced higher yields than where herbicides were applied later. Optimum time for herbicide application was when wheat was in the two to three tiller stage and weeds were small, five to six leaf stage. Delaying the application of herbicides beyond the critical period of competition, which is determined by stage of growth of weeds and wheat, resulted in a continuing decrease in wheat yields. Chemicals which produced satisfactory weed control and increased wheat yields were, 2,4-D, 2,4-D + 2,4,5-T, bromoxynil + MCPA, and terbutryn + 2,4-D combinations. The terbutryn + 2,4-D combination needs further research because of possible phytotoxicity to wheat. It was concluded that using only herbicides now available in Turkey, wheat yield increases of 25 to 50% or more are possible by applying herbicides at the optimum time.

Non-Chemical Weed Control is the first book to present an overview of plant crop protection against non-food plants using non-chemical means. Plants growing wild—particularly unwanted plants found in cultivated ground to the exclusion of the desired crop—have been treated with herbicides and chemical treatments in the past. As concern over environmental, food and consumer safety increases, research has turned to alternatives, including the use of cover crops, thermal treatments and biotechnology to reduce and eliminate unwanted plants. This book provides insight into existing and emerging alternative crop protection methods and includes lessons learned from past methodologies. As crop production resources decline while consumer concerns over safety increase, the effective control of weeds is imperative to insure the maximum possible levels of soil, sunlight and nutrients reach the crop plants. Allows reader to identify the most appropriate solution based on their individual use or case Provides researchers, students and growers with current concepts regarding the use of modern, environment-friendly weed control techniques Presents methods of weed management—an important part of integrated weed management in the future Exploits the knowledge gained from past sustainable weed management efforts

Landraces possess a very large genetic base in population structure and are dynamic populations of cultivated plants with historical origin, distinct identity, and without any formal crop improvement. They are often genetically diverse, locally adapted, and associated with traditional farming systems. Resistance genes to biotic and abiotic stress factors, which are especially diversified in landraces, are of great interest to plant breeders, faced with global climate challenge. In addition, gene pools made of different landraces grown in different ecological conditions can be used for wheat breeding to enhance quality; yield and other desirable agricultural parameters. An estimated 75% of the genetic diversity of crop plants was lost in the last century due to the replacement of high yielding modern varieties. There is, thus, an urgent need to preserve existing species, not only for posterity but also as a means to secure food supply for a rising world population. In this book, we provide an overview of wheat landraces with special attention to genetic diversities, conservation, and utilization.
