Accurate technologies of agricultural crops cultivation for organic farming

The article presents the results of many years of experiments on the development of energy-saving farming systems. Preference in crop rotations should be given to multi-depth combined treatments that provide high productivity and are characterized by high-energy efficiency. Data on the yield of grain and leguminous crops in a six-field grain crop rotation with constant dump and combined longline tillage shows that the yield of oats in the first year of rotation according to the experimental variants was the same and amounted to 3.60 t/ha. In the second year of winter wheat yield in the variant with longline tillage was by 0.20 t/ha more in comparison with a plow on row, in the third year the difference in yield of spring barley on options for primary processing amounted to 0.30 t/ha in favor of combined tiered processing, in the fourth year the yield of peas has also been found to 0.40 t/ha more, also on the option of combined longline processing in the fifth year of the rotation crop of winter triticale. The yield of oats was 0.30 t/ha higher, and in the sixth year the yield of oats was 0.40 t/ha higher on the variant of combined longline processing.

Growth and Productivity of Oats (Avena sativa L.) as Influenced by Fly Ash and Phosphorous Levels in Indo-Gangetic Plains of India

Background: Dairy farming is one of the oldest and well established subsidiary occupation and most widely adopted by all over farming community of Punjab state. Every farmer, if wish to start any entrepreneurship along with agriculture-First Think upon Dairy Farming. The latest training, new techniques and research work help in making this business work better. There is a need for substantial increase in the current yield of green fodder to provide complete and good quality feed to the animals. The current study aimed to study the effect of fly ash and phosphorous on the growth and fodder and grain yields of dual purpose oats. Methods: Field experiments were conducted at Research Farm, College of Agriculture, Guru Kashi University, Talwandi Sabo, Bathinda to study the effect of different levels of fly ash and phosphorous on growth and productivity of oats during rabi seasons in 2018-19 and 2019-20. The trial was laid out in split plot design with three levels of fly ash (0, 5 and 10 t ha-1) in main plot and four phosphorous levels (0, 10, 20 and 40 kg P2O5 ha-1) in sub plot, replicated thrice. Result: Fly ash @ 10 t ha-1 recorded highest plant height, dry matter accumulation, leaf area index, number of effective tillers/m row length, number of seeds/spike, 1000-grain weight, grain yield, straw yield and biological yield than control and 5 t ha-1. The per cent increase of grain yield in fly ash @ 10 t ha-1 was 8.69 and 18.11 over 5 t fly ash ha-1 and control, respectively. Phosphorous @ 40 kg P2O5 ha-1 resulted in higher growth characters, yield attributing characters and productivity of oats. Phosphorous @ 40 kg P2O5 ha-1 (21.35 q ha-1) and 20 kg P2O5 ha-1 (20.87 q ha-1) treatments produced statistically similar grain yield of oats. Phosphorous @ 20 and 40 kg P2O5 ha-1 recorded 20.29 and 23.05% higher grain yield than 0 kg P2O5 ha-1, respectively. Application of P2O5 @ 40 kg ha-1 along with application of fly ash @ 5 and 10 t ha-1 produced statistically similar fodder yield of oats. The highest grain yield (22.97 q ha-1) was recorded in plots treated with the application of P2O5 @ 40 kg ha-1 along with the application of fly ash @ 10 t ha-1 and it was statistically at par with 20 kg P2O5 ha-1 and application of fly ash @ 10 t ha-1. The highest grain yield (22.97 q ha-1) was recorded in plots applied with P2O5 @ 40 kg ha-1 along with fly ash @ 10 t ha-1 and it was statistically at par with 20 kg P2O5 ha-1 and fly ash @ 10 t ha-1.

ПОСЛЕДЕЙСТВИЕ ОСАДКОВ СТОЧНЫХ ВОД Г. ПЕНЗЫ И ПРИРОДНОГО ЦЕОЛИТА НА УРОЖАЙНОСТЬ И КАЧЕСТВО РАСТЕНИЕВОДЧЕСКОЙ ПРОДУКЦИИ

В условиях низкого уровня использования минеральных удобрений в земледелии в связи с высокой их стоимостью и почти полного отсутствия органических удобрений разработка и внедрение в земледельческую практику технологических приемов использования альтернативных источников органического вещества и элементов питания является актуальным направлением современного земледелия. Задача исследований заключалась в изучении последействия мелиоративных норм осадков сточных вод г. Пенза и их сочетаний с цеолитсодержащей породой на урожайность и качество растениеводческой продукции. Исследования проводились в первом агропочвенном районе Пензенской области в зернопаропропашном севообороте в период с 2014 по 2019 гг. Установлено, что наиболее существенное влияние на урожайность зерна овса и гороха оказали повышенные нормы осадков городских сточных вод с цеолитсодержащей породой. Урожайность овса на их фоне возрастала на 43,5-44,2, урожайность гороха на 48,9-49,8. Сбор переваримого протеина в посевах овса на их фоне составлял 487,9-490,3 кг/га, содержание белка в зерне гороха увеличивалось на 2,3-2,7. Осадки городских сточных вод в чистом виде и в комплексе с цеолитсодержащей породой повышали концентрацию тяжелых металлов в зерне овса и гороха. Однако, концентрация тяжелых металлов была существенно ниже ПДК. Цеолитсодержащая порода снижала поступление тяжелых металлов в товарную часть растениеводческой продукции.In conditions of a low level of use of mineral fertilizers in agriculture due to their high cost and the almost complete absence of organic fertilizers, the development and implementation of technological methods for using alternative sources of organic matter and nutrients in agricultural practice is an important area of modern farming.The objective of the research was to study the aftereffect of reclamation norms of sewage sludge in the city of Penza and their combinations with zeolite-containing rocks on the yield and quality of crop products. The studies were conducted in the first agricultural-soil region of the Penza region in grain-crop rotation in the period from 2014 to 2019. It was established that the most significant effect on the grain yield of oats and peas was exerted by increased sediments rates of urban wastewater with zeolite-containing rock. The yield of oats against their background increased by 43.5-44.2, the productivity of peas - by 48.9-49.8. The collection of digestible protein in oat crops against their background was 487.9-490.3 kg/ha, the protein content in pea grain increased by 2.3-2.7. Sediments of urban wastewater in its pure form and in combination with zeolite-containing rock increased the concentration of heavy metals in the grain of oats and peas. However, the concentration of heavy metals was significantly lower than the maximum permissible concentration. The zeolite-containing rock reduced the influx of heavy metals into the marketable part of crop production.

The Influence of Climate Change on Oat Productivity in the Steppe Zone of Ukraine

Purpose. To assess the impact of climate change on oat productivity in the steppe zone of Ukraine. Methods. Statistical, mathematical modeling. Results. It is established that the seed sowing and of seedling emergence will be postponed to an earlier date. More favorable conditions are expected for the formation of seedling emergence, growth and development of plants during the period of "seedling - heading". Reduced background temperature will lead to a decrease in the value of total evaporation and a decrease in moisture demand by 47–58 mm. The moisture content of the first vegetation period will be significantly higher than in the middle perennial years. Agroclimatic conditions of the second half of the vegetation period of oats will develop at low temperatures and uneven moisture across the territory. The demand for moisture will increase everywhere by 12–28 mm. The supply of moisture will decrease. Using the model of the formation of the yield of agricultural crops, the influence of changes in the agro-climatic conditions of the growing season on the indicators of photosynthetic productivity of oat crops and the formation of the yield was assessed. Conclusions. It was concluded that a possible increase in the yield of oats in the Steppe zone of Ukraine under the implementation of climatic scenarios and early sowing terms. Changes in agroclimatic conditions in the implementation of climatic scenarios will lead to changes in the photosynthetic activity of oat crops: the relative leaf area will increase, the increase in total plant mass will increase, the photosynthetic potential of crops will grow during the growing season. Proposed cartographic schemes of the expected yield of oats in the Steppe zone of Ukraine.

Features of the interaction of vetch and oats in mixed crops at different levels of nitrogen nutrition

Application of nitrogen fertilizers at a dose of 30 kg/ha under the vetch and oat mixture practically does not affect the yield of vetch, but increases the yield of oats by an average of 21.7% and the yield of the vetch and oat mixture by 11.1 %. Nitrogen fertilizers in doses of 60 and 90 kg / ha reduce the yield of vetch in the vetch and oat mixture by an average of 21.5% and 31.6%, respectively, but increase the yield of oats by 47.8% and 73.9%, respectively; the yield of the mixture increases by 15.7% and 25.1%.The payback of 1 kg of mineral nitrogen by adding the yield of the vetch -oat mixture was at a dose of N30+6.3 kg/kg, at doses of N60 and N90 + 4.5 kg/kg and +4.8 kg / kg, respectively.

The influence of mineral fertilizers and soil treatment methods on the yield of oats

The article summarizes the results of studies (2013 and 2018) conducted on leached heavy loam Chernozem in the Republic of Mordovia. The object of study is oats (Horizon variety). In the experiment, against the background of plowing, tillage and disking, the effect of mineral fertilizers was studied, which were represented by a complete mineral fertilizer (N32P32K32 –background), and fertilizing with mineral nitrogen in doses of 30 and 60 kg of active gradient/ha against this background. Analysis of oat yield shows that the collection of grain plowing in options without the use of mineral fertilizers (2.34 t/ha) had an advantage over the tillage and disking (2.15 and 2.04 t/ha), and in general, the experience increased the yield of oats by 0.43 and 0.53 t/ha. The maximum yield increases from the use of mineral fertilizers were obtained from the background of plowing, their value ranged from 0.49 to 1.03 t/ha compared with the option without fertilizers, there were less increases on the background of non-dump treatment of 0.21–0.57 t/ha and disking of 0.22–0.62 t/ha. Fertilizing with mineral nitrogen at a dose of 30 kg of active gradient/ha regardless of the methods of tillage showed an almost equivalent increase in the yield of oats by 0.20–0.24 t/ha compared with the background options (2.83, 2.36 and 2.26 t/ha, respectively, plowing, dump-free processing and disking). The most effective (an increase of 0.54 t/ha) was fertilizing with nitrogen at a dose of 60 kg of active gradient/ha against the background of applying a full mineral fertilizer using plowing.

Influence of Plants Protection Means on the Productivity of Naked Oats Under the Conditions of the Western Forest-Steppe of Ukraine

The article presents the results of field research on the production of naked oats yields, depending on the means of plant protection under the conditions of the western forest-steppe of Ukraine. The object of research was the belligerent variety Avgol. The purpose of our research was to study the effects of various protection schemes to obtain the highest yield of oats. In the process of conducting research, the field method of research was used: - to determine the influence of the elements of cultivation technology. From the results of the research, it can be seen that the means of plant protection have an effect on the yield of naked oats. The smallest it was in the first variant with the introduction of the Granstar herbicide (25 g / ha) and was 4.87 t / ha. Intensification of cultivation technology with morphorigulator Stabilan (0.8 l / ha) yields of oats increased to 5.35 t / ha, which is 0.45 t / ha more than the previous one. The morphoregulator thickened the walls of the straw, reduced the height of the plants, and thus protected from falling. In the third variant (Granstar (25g / ha) + Stabilan (0.8l / ha) + Falcon fungicide (0.8 l / ha), the yield increase was 4.98 t / ha, and the growth to the first was 0.96 t / ha Fungicide Falcon protected crops of oats from the defeat of septoriosis, powdery mildew, spots in the phase of tubing. It provided an increase in yields by 0.51 t / ha. Two-time introduction of fungicides (Granstar (25 g / ha) + Stabilan (0.8 l / ha) + Falcon (0.8 l / ha) + Rex Duo fungicide (0.6 l / ha)) positively affected oat crops and contributed to an increase yields to 6.09 t / ha, which is 1.22 t / ha of the control variant. The highest yields over the years have been observed in the fifth variant (Granstar (25 g / ha) + Stabilan (0.8 l / ha) + Falcon (0.8 l / ha) + Rex Duo (0.6 l / ha) + insecticide Fastak (0.2 l / ha)), where it was 6.15 t / ha, which is 1.28 t / ha more than the variant with the application of only Granstar herbicide (25 g / ha). However, the use of insecticides was ineffective in comparison with fungicides. The increase in the yield from the insecticide Fastak was only 0.06 t / ha. Depending on the protection schemes, the protein content did not change significantly and was at 14.42 - 14.44%. Consequently, the yield of naked oat of the variety Avogol due to the introduction of herbicide, morpho-regulator, fungicides and insecticide increased by 1.28 t / ha
