There were analyzed and disclosed the basic components of arable farming systems and their Meaning, the current state and scientific principles in the context of the further development of field crop cultivation in the conditions of Western Forest-Steppe. The purpose of research. To study an effect of alternation of crop in crop rotation in conditions of brief rotation on the soil water regime, productivity and economic efficiency. Methods. Field, laboratory, comparative and analytical. Results. The results of researches on study of productivity of four-field crop rotations with short rotation depending on their saturation by the grain and tilled cultures, of various use of mineral fertilizers, green manure crops and collateral products which were conducted during 2014-2015 in the stationary experiment of the scientific and technological department of plant growing and arable farming, of the TDSGDS of the IKSGP of NAAN are resulted In the article. The elements of the biologization of farming are the basis of our development of crop rotations with short rotation. The study of the effect of green manure crops and collateral products in four-field crop rotations with a different set of crops on the change of soil fertility and productivity of crop rotations as a whole was carried out to this purpose. According to the results of the research, is provided the information on the effectiveness of improving the field crop rotations with short rotation with varying degrees of saturation by grain and tilled crops, that ensure the production of environmentally friendly products, reducing the cost of grain, improving the quality of marketable products. The study of the effect of alternation of crop in crop rotation in conditions of brief rotation on the soil water regime, productivity and economic efficiency showed that an increase in crop rotation productivity is observed in short-rotation crop rotations, if they are saturated by grain crops up to 100%, cereals crops reduction to 50% in crop rotations contributes to a decrease in crop productivity. Conclusion. Thus, the results of the research showed that with the correct construction of short rotational crop rotations, such problems as rational use of nutrients and soil moisture, control of weeds and pests of agricultural crops, improvement of the physical and chemical properties of the soil, increased efficiency in the use of fertilizers and equipment, Cheapening of the received agricultural product may be solved.

AbstractOrganic farmers in western Canada rely on tillage to control weeds and incorporate crop residues that could plug mechanical weed-control implements. However, tillage significantly increases the risk of soil erosion. For farmers seeking to reduce or eliminate tillage, potential alternatives include mowing or using a roller crimper for terminating green manure crops (cover crops) or using a minimum tillage (min-till) rotary hoe for mechanically controlling weeds. Although many researchers have studied organic crop production in western Canada, few have studied no-till organic production practices. Two studies were recently conducted in Saskatchewan to determine the efficacy of the following alternatives to tillage: mowing and roller crimping for weed control, and min-till rotary hoeing weed control in field pea (Pisum sativum L.). The first study compared mowing and roller crimping with tillage when terminating faba bean (Vicia faba L.) and field pea green manure crops. Early termination of annual green manure crops with roller crimping or mowing resulted in less weed regrowth compared with tillage. When compared with faba bean, field pea produced greater crop biomass, suppressed weeds better and had less regrowth. Wheat yields following pea were not affected by the method of termination. Thus, this first study indicated that roller crimping and mowing are viable alternatives to tillage to terminate field pea green manure crops. The second study evaluated the tolerance and efficacy of a min-till rotary harrow in no-till field pea production. The min-till rotary hoe was able to operate in no-till cereal residues and multiple passes did not affect the level of residue cover. Field pea exhibited excellent tolerance to the min-till rotary hoe. Good weed control occurred with multiple rotary hoe passes, and pea seed yield was 87% of the yield obtained in the herbicide-treated check. Therefore, this second study demonstrated that min-till rotary hoeing effectively controls many small seeded annual weeds in the presence of crop residue and thus can reduce the need for tillage in organic-cropping systems.

Present day agricultural practices are posing a serious threat to the human population due to unscrupulous use of chemical fertilizers and pesticides. Conventional agricultural practices wherein large quantities and unscrupulous use of chemical fertilizers and pesticides are no longer safer as it directly enter the food chain. Hence, organic cultivation of vegetables is gaining momentum among the growing population. Organic practices rely on crop rotations, crop residues, plant and animal manures, growing of legume and green manure crops and biological control of pests and diseases. It aims to combine tradition, innovation and science in a balanced proportion to utilize the environment in safer manner and maintain ecological balance. Organic cultivation assures protection of the environment and plays a major role on the economy of a nation. Sustainable production of organic vegetables needs to be ensured to fetch premium price in the domestic as well as international markets. Organic farming has shown expansion in the recent years in the European countries offering scope for a better price in the international market.

The humus condition of soils of Chernihiv region has been studied. The dynamics of humus content in the soils of the region during six rounds (1986–2015) of agrochemical certification of agricultural lands is generalized and analyzed. In comparison with the 5th round (1986–1990), there was a discrepancy between the processes of stabilization and increase of humus content in most districts and in the region as a whole in the ninth round (2006–2010), and in some districts in the tenth round (2011–2015) against the background of a sharp decrease in the application of organic fertilizers. It was found that the stabilization of humus content in the soils of the region during the V–VIII rounds of agrochemical certification and a sharp increase in its content in the ninth round, against a significant reduction of organic matter, correlates with the withdrawal of eroded, low-yielding lands with low humus content (r=0.76). Analyzing the dynamics of humus content over thirty years of research,it was found that its content has increased in all climatic zones, as well as in nineteen of the twenty-two districts of the region. The increase of the indicator is in the range of 0.01–0.72%, while in all districts there is a significant reduction of the surveyed areas and only in three districts of the region there is a decrease in the humus content. According to the results of the 10th round of agrochemical certification, the soils of Chernihiv region are characterized by an average humus content of 2.41%. The highest humus content is characterized by the soils of Bakhmatsky (3.56%), Talalaivsky (3.33%) and Pryluky (3.32%) districts, and the lowest — NovgorodSiversky (1.57%). Increasing the sown area of green manure crops, plowing straw and the use of other elements of biologization of agriculture are important factors in increasing the weighted average humus content in the soils of Chernihiv region.
