Fertilizer System

One of the main factors of intensification in crop production is the effective using of mineral fertilizers. There must be a clear and correct approach to the development of the crop fertilizer system, in the context of the current reduction of the soil’s natural fertility and high environmental burden. A scientifically sound fertilization system must ensure not only high crop yields with optimum product quality indicators, but also the preservation or different increase of soil fertility while maintaining environmental safety. The effectiveness of mineral fertilizers depends on both the ratio of nutrients and their forms. With the same amount of active substance, different forms of fertilizers provide different results, due to the physiological characteristics of fertilizers and plants. The rational application of fertilizers is only possible when understanding the deep connection between soil agrochemistry and plant physiology. The highest yield of sunflower hybrids was obtained in the case of fertilizer application at a dose of N60P90. The application of mineral fertilizers with different doses increases the yield of sunflower hybrids by 0.16-0.43 t / ha. However, the level of mineral fertilizer efficiency varies and depends on other factors. Therefore, the question of the effectiveness of the application of mineral fertilizers during the cultivation of sunflower in the conditions of the zone of insufficient moistening of the Steppe of Ukraine needs more systematic study. Key words: sunflower, mineral fertilizers, mineral nutrition, cultivation technology, yield, plant density, biological yield.

Польовий дослід закладали на колекційно-демонстративному полі у ВП НУБіП України «Мукачівський аграрний коледж» у Закарпатській області на дерново-підзолистих важкосуглинкових ґрунтах. Встановлено, що в умовах Закарпаття веґетація середньостиглих сортів квасолі залежно від сортових особливостей, удобрення та інокуляції насіння варіює від 93 до 113 діб. Збільшення норми внесення мінеральних добрив до N60P20K25 подовжує веґетаційний період сортів квасолі звичайної на 8–13 діб. За передпосівної обробки насіння «Ризобофітом Р» тривалість веґетації та настання фенофаз квасолі звичайної також подовжувалась від 2 до 5 діб. Сорт Надія достигає раніше на 8–10 діб. The article is devoted to the results of the study of the duration of the vegetation period of the beans and its individual phases for mid-late varieties of Mavka, Pearl, Nadiya depending on the level of fertilization and inoculation of seeds by «Risobofit P» in the conditions of Transcarpathia of Ukraine. Field experiments were laid on the collector-demonstration field at the NUPiP of Ukraine «Mukachevo Agrarian College» in the Transcarpathian region on turf-podzolic heavy-soil soils. Mineral fertilizers were introduced in the form of ammonium nitrate (34.4 % N), phosphorous flour (30 % P), kalimagnesia (26–28 % K, 11–18 % Mg); additionally carried out liming of soils at the rate of 3 t/ha. The inoculation of seed beans was carried out on the day of sowing by «Risobofit» (mark P), which contains the symbiotic nitrogen fixing bacteria of the genus Rhizobium phaseoli from the Institute of Agroecology and Nature Management of NAAS. It has been established that in the conditions of Transcarpathia, the vegetation of mid-season varieties of beans varies from 93 to 113 days depending on variety characteristics, fertilization and inoculation of seeds. Hope grade reached earlier than others and the period of vegetation it was 8–10 days shorter. Application of seed inoculation prolonged the period of vegetation of beans varieties compared to variants without seed inoculation on a different background of fertilizer for 3–5 days. The increase in nitrogen fertilizers up to 60 kg/ha prolonged the vegetation of the studied bean varieties for 8–13 days. For the application of nitrogen fertilizers in the normal range from 45 to 60 kg/ha against the background of PK, the vegetation period was the same, both in the variants with and without inoculation. The introduction of nitrogen fertilizers in the normal range from 45 to 60 kg/ha on the background of PK resulted in inhibition of the nitrogenase activity of the tubers on the roots of the studied soybean varieties and the plant nutrition was carried out solely at the expense of mineral fertilizer forms.

Flood recession farming is as an important supplement to rainfed agriculture in West Africa. Every year, large areas are flooded along riverbanks and temporary lakes. When water recedes from the flooded areas, farmers plant crops. This study describes the flood recession farming in the Yelimane district of Kayes region in Mali and assesses different ways to intensify the system. The use of external inputs in this system is minimal. Field experiments were undertaken over two years to test crop establishment methods, soil tillage, increasing plant density, use of organic and mineral fertilizer, and improved varieties. These technologies increased sorghum yield as compared to the control in the following descending order: Seed priming + fertilizer (77.1%), NPK + organic fertilizer (74%), seedling transplantation + micro fertilization (61.3%), improved varieties (49%), mounding (34%), and urea application (24.9%). The technology seed priming in combination with mineral fertilizers was promising because of the high yield and the low labor demand. Nitrogen fertilizer is needed in flood recession agriculture as the soils and the deposited sediments are low in nitrogen. Farmers’ choice of technology will depend on the yield level, net return per hectare, labor use, and access to inputs.

Were described results of study effect of fertilizers and seed inoculation on productivity formation pea varieties with leafless morphotype of leaves on typical black soils of northern Forest-Steppe Right-Bank Ukraine. Research was conducted in 2014˗2016’s at field experiment at «Agronomic Research Station and in laboratory of analytical research in the department of Plant growing NULES of Ukraine. The purpose of the study was to determine the features of formation of efficiency of pea varieties with leaves whiskered morphotype depending on fertilizer and seed inoculation in the northern forest-steppe of the Right-Bank Ukraine. At the day of sowing pea seeds were treated by suspended biopreparation Ryzohumin and biological preparation Hetomik. Mineral fertilizers were applied according to the experimental scheme: on the D1-D6, options nitrogen fertilizers - in seedbed preparation, phosphorus-potassium - the main processing; on D7-D12 variants on the background of complete mineral fertilizer a foliar fertilizer. Was conducted feeding by the stages growth and development of plants BBCH 12−13, 55−59, 61−71. In average in years of study plant density of variety Tsarevych varied within 87,7−105,3 (without inoculation) and 91,7−109,3 (with inoculation) plants/m2. Variety Deviz showed the similar dependence and in experiment with­ out inoculation plants density was within 86,7−102,3 plants/m2 and depended from the variant of fertilization, in inoculating seeds − 90,7−106,3 plants/m2 respectively. Basing on the obtained data, we can note a positive effect of seed inoculation in conjunction with chemical fertilizer Hetomik on survival pea plants during the growing season. It was established that increasing in grain weight per plant significantly depends from feedings by nitrogen and phosphorus fertilizers by the stages growth and development of plant, and inoculation of seeds. Thus, in variants of experiment, where was used seed inoculation and was conducted foliar feeding by nitrogen and phosphorus fertil­ izers (D7−D9) grain mass in variety Deviz at 1,32 g/plant exceeded variant D1 (without fertilizers), and in variety Tsarevych - at 1,18 g/plant respectively. With inoculation of seeds was increased number of beans on the plant – up to 7, 33 (D9) in variety Deviz and to 8, 67 (D2) pcs/plant in variety Tsarevych. The weight of grain from the plant at variety Deviz in variants D7–D9 exceeded variant D1 on 0‚83 g/plant, at variety Tsarevych on 0‚93 g /plant in variants without inoculation. The maxi­ mum yield at level 4‚99 tones/ha of variety Tsarevych and 4‚40 t /ha of variety Deviz was provided by combination of seeds inoculation and fertilizers. Found that optimal growth and development of pea plants variety Tsarevych was reach with application N30P90K90 (D6), and of variety Deviz – N30P60K60 (D12) with three foliar feedings at stages of growth and development of plants.

Significant Difference

The efficiency of influence of Plantafol (10.54.10) foliage application on soybeans in soil and climatic conditions of the Ternopil region was investigated. It was found that Plantafol increased the green weight of top and plant density, the total mass of grain per plant, its significance and therefore increased the grain crop by 4.9 c/ha.The crop growth was due to the formation of 15.0% higher biomass green weight of top with higher plant stand by 8% and the increase of seed productivity mainly by increasing of the total weight of seeds in plants by 10.2% and its significance by 7.9 % in comparison with the control. By the influence of Plantafol, there was an increase of the height of beans fastening by 6.4%, as well as a tendency to increase the number of beans by 5.7% and the number of seeds per plant by 2.1%.The chlorophyll fluorescence induction technique was used to isolate a group of fluorescence parameters of chlorophyll a, in particular φNPQ, φNO, which can determinate variations in the productivity of the variety, as they are sensitive to the foliage application.There wasn’t found the direct influence of the mineral fertilizer on the quantum yield of photochemistry PS II (ФPSII). At the same time, the abundance of chlorophyll (SPAD) increased.It is assumed that the decrease of the ECSt level, observed under the conditions of Plantafol foliage application of plants, led to the decrease of NPQt and φNPQ levels in soybean.In the absence of significant difference in the rate of linear electron flux in the experimental and control groups, Plantafol decreases the NPQt level and causes the increase of the total number of active RC FS I.The obtained data proved the significance and the perspective of foliage application using as of complex mineral fertilizers during soybean cultivation that increases its productivity in local soil and climatic conditions.The Plantafol  reduces the negative effect of some nutritional elements in soil and increases the soybean crop in the conditions of Ternopil region by stimulating photosynthetic, growth and production processes.
