A field experiment was conducted in Kanan region, province of Diyala, Iraq during the winter season 2016-2017 to screen herbicides for wheat cultivation. Six herbicides viz., Salix, Cronus, Pallas, Granstar, Topic and Atlantis were sprayed as post-emergence with second irrigation 54 days after crop sowing. Wheat growth parameters viz Crop height, Spike length and number of grains per spike were a higher in Granstar&Topic (105.2 cm, 12.6 cm, 51.4) respectively, 1000 grain weight were noted with Atlantis (40.9 g). followed by Granstar&Topic (39.2 g), Number of plants / m2 was a higher in Atlantis (430), Grain yield g \ acre was significantly increased in Granstar&Topic (1848 g) weeds growth parameters like Number of weeds / m2, Dry weight of weeds g, Weed control % and Weeds inhibition % were lower in Salix&cronos (0.0,0.0 g,100%,100%) respectively.

Wheat Cultivation

In modern agriculture, on large-scale farms using monoculture, reduced tillage and intense chemical protection, the phenomenon of herbicide resistance in weeds is the cause of ecological and economic losses. More and more attempts are made to answer the question about the profitability of reducing agrotechnical treatments and intensifying chemical methods of weed control with a simultaneous intensification of the problem of herbicide resistance in weeds occurring in winter wheat crops, which dominates the structure of cereal sowing in Poland. The main objective of the study was to evaluate the costs of weed control for winter wheat cultivation on large-scale farms where there was no problem of weed resistance and on farms where resistant biotypes were identified. The research was based on a survey conducted among owners of farms cultivating winter wheat in 2019. The collected data were elaborated using basic methods of descriptive statistics and economic analysis. Based on the research results, it was found that with an increase in the area of farms, reduced tillage and monoculture are used more frequently than conventional tillage and crop rotation. At the same time, the commonly used chemical weed control methods are more frequently applied than mechanical ones. Economic efficiency indicators for winter wheat protection against weeds indicate a decrease in this efficiency with an increase in farm size. This is because the larger the farms, the more frequently the occurrence of resistant weed biotypes, which was confirmed by laboratory tests, and farmers more often assumed that such a problem occurred on their farms

Weed Resistance

The main purpose of the article is to assess the economic efficiency of wheat protection in conditions of the occurrence of weed resistance to herbicides in a selected large-scale farm (case study). In modern agriculture, especially in large-scale farms using monoculture, zero tillage and intensive chemical protection, the emerging phenomenon of weed resistance to herbicides is a cause of ecological and economic losses. In Poland, as well as the world, the problem of weed resistance is mainly noted in the case of wheat cultivation, which is ranked first in terms of sown area. Therefore, more and more often attempts are being made to answer the question, what is the profitability of performed weed control operations with the simultaneous occurrence of herbicide resistance. Empirical research was conducted on the basis of data recorded in the book of profits and losses recorded by the farm owner in 2014-2018. The collected data was developed using economic analysis and statistical methods. It was found that, in the examined period, due to the growing problem of the presence of resistant weeds, the use of products to control them increased and the costs of protecting wheat cultivation also increased. The low effectiveness of chemical weed control treatments resulted in a change in the structure of crops in the researched farm in the last year of the study.

Crop Competition

Successful weed control in small grains involves using good management practices in all phases of production. In Florida, winter weeds compete with small grains for moisture, nutrients, and light, with the greatest amount of competition occurring during the first six to eight weeks after planting. Weeds also cause harvest problems the following spring when the small grain is mature. This 4-page publication discusses crop competition, knowing your weeds, and chemical control. Written by J. A. Ferrell, G. E. MacDonald, and P. Devkota, and published by the UF/IFAS Agronomy Department, revised May 2020.

New Cultivars

This paper, as well as being a testimonial to the benefit the writer has received from the Grassland Association, shows how the knowledge of scientists has been used to increase lucerne seed yields by methods of growing resistant cultivars especially for seed production as opposed to growing for hay, silage or grazing. It shows how new cultivars can be multiplied quickly by growing two crops in one year, one in each hemisphere, by using low seeding rates, wide plant spacing and very good weed control. Increased flowering of the crop has been achieved by the use of boron and the choice of time of closing; better pollination has been achieved by the use of more efficient bees - two varieties of which have been imported from North America. Weed and insect pest control and the use of a desiccant at harvest are contributing to a four-fold increase in seed yield, which should double again soon,
