The Impact

The research explores the relation between productivity of binary grass mixture and mineral nutrition. The hypothesis assumes that nutrient value of the same forage depends on mineral nutrition of forage grasses. According to purpose of research, the authors specified the task which is seen to analyze the impact of mineral fertilizers on productivity and nutrition of forage mass of binary grass mixture sown under the cover. The object of the research is a binary grass mixture based on alfalfa (Medicago + sainfoin). Sowing was carried out under the barley and Sinapis cover on two mineral backgrounds: control (without fertilizers) and fertilized. Fertilizers were applied the day before sowing. Crop yield and the quality of harvested mass were assessed in the appropriate period which was the stage of Medicago budding. Two-year industrial and economic experiment highlighted necessity and efficiency of sowing Medicago binar grass mixtures under Sinapis cover with 25% lower sowing rate and apply mineral fertilizers dosed as N23P60K60 in the forest-steppe of Novosibirsk region. This application contributed to the highest output of metabolic energy in dry matter (37 GJ/ha). The authors observed a positive tendency on harvesting from 1 ha of fodder units (2.14 tons), digestible protein (0.35 tons), as well as the yield of dry (3.58 tons) and green mass (13.7 tons). In this variant the authors observed the highest output of metabolic energy in dry matter (37 GJ/ha). There was a positive tendency to harvest fodder units (2.14 tons), digestible protein (0.35 tons) pro 1 ha and get dry (3.58 tons) and green mass (13.7 tons).

The purpose of the research was to study the effect of planting time on the formation of productivity of Hungarian sainfoin when grown for green forage. Methods are field, laboratory, statistical, correlation and regression relationships. Research results. It is established that under uneven humidity and high temperature regime in the year of sowing, Hungarian sainfoin formed two yields under spring planting date and one yield under summer planting date. In the second and third years of growth, no significant effect of the planting date on the stages of organogenesis of Hungarian sainfoin was found, where the maturity of the herbage was reached simultaneously. Productivity of Hungarian sainfoin was only conditioned by hydrothermal conditions, where the yield of green mass averaged 45.9—49.6 t/ha with crude protein content of 1.58—1.73 t/ha. At the same time, the highest dry matter yield of 10.25 t/ha and crude protein of 1.73 t/ha was provided by agrophytocenosis when sown on April 12. The productivity index of Hungarian sainfoin in the first year of life was determined, where the highest indicator was obtained during the early spring sowing period (29.04) – 7.85 kg/ha of dry matter per 1 hour of light day, whereas for the recommended summer sowing period was 1.13 kg/ha, or 6.9 times lower. The correlation equation between dry matter output, duration of daylight and the sum of precipitation from full shoots to the beginning of flowering in the first year of life is described. It is found that with increase of precipitation by 1 mm the dry matter output increases by 1.53 % and there is a tendency increase with increasing the length of daylight by 1 minute. Conclusions. It has been established that on gray forest soils of the right-bank Forest-Steppe, over two years of intensive use of the grass stand, regardless of hydrothermal conditions, Hungarian saifoin provided a stable forage productivity when sown in spring. Thus, dry matter yield was 9.38—10.25 t/ha with crude protein content of 1.58—1.73 t/ha. In particular, as for summer planting date, July 20 appeared to be the most effective planting date, which provided dry matter yield of 9.78 t/ha with crude protein content of 1.61 t/ha.

In the soil and climatic conditions of the Right Bank Forest-Steppe, regardless of the action of abiotic and biotic factors during the growing season, high adaptability of alfalfa was established for different geographical origins, namely the natural zone of the Forest-Steppe, Polissya, Steppe Ukraine and Serbia. It was found that under the weather conditions of 2016 year alfalfa varieties reacted differently to changes in temperature and moisture during the growing season. It is important to note the effectiveness of phosphorus-potassium fertilizers applied directly to alfalfa coverless method of sowing. In the year of sowing, alfalfa formed a powerful herbage and provided two slopes with a yield of green mass at the level of 20,13-29,80 t/ha with a dry matter yield of 4,80-6,69 t/ha. For the second year of vegetation, alfalfa was carried out according to the regimes, which considered the phases of growth and development (budding, beginning of flowering and flowering). In the first mode of cutting management (all slopes in the budding phase) it is advisable to identify three varieties of Unitro, Nasoloda and Rosana, which provided a gross dry matter of 10,41-10,48 and 2,29-2,31 t/ha of crude protein. The productivity of alfalfa increased with late term cutting - at the beginning of flowering and a combination of slopes (3rd mode). The dry matter yield was 11,40-12,62 and 2,35-2,51 t/ha of crude protein (second regime) and the indicators increased under the third regime, especially dry matter 13,58-15,80 t/ha and decreased to 2,37-2,41 t/ha of crude protein. The increase in dry matter of the second mode increased by 9,5-23,1% and crude protein by 2,6-20,5%, and in the third mode of use of alfalfa it was 2,3-11,2%, compared to the mode of mowing the grass in the budding phase. During the third year of vegetation under favorable agroecological conditions for growth and development of alfalfa plants, the studied varieties provided four slopes regardless of the mode of use of grass with a dry matter yield of 15,43-20,58 and 3,21-4,02 t/ha of crude protein. During the second and third years of vegetation from the studied modes of use of alfalfa grass for fodder purposes, the highest yield of crude protein 5,27-6,53 t/ha varieties provided for the alienation of crops at the beginning of the flowering phase, which was on average 6,0-7,1% higher than when mowing all slopes in the budding phase and a combination of slopes in the phases of growth and development (3rd mode). Thus, in the conditions of the Forest-Steppe of the right bank on gray forest soils alfalfa, regardless of geographical origin, adapted to growing conditions and provided stable productivity indicators regardless of the regime of grass use with observance of elements of cultivation technology.

The development of animal husbandry requires the annual production of a sufficient amount of high-quality feed, their nutritional balance, which cannot be achieved without perennial legumes and legume-cereal mixtures. The content of nutrients in the dry matter of forage depends on both the composition of the grass mixture and the mode of use of the grass stand. Therefore, the main reference point for modern feed production should be an innovative development model that will ensure the production of feed with specified quality parameters. Goal and tasks. Determine the effect of the composition of grass mixtures and the mode of use on the fodder value of the grass stand, in particular, the content in dry matter of fodder units, crude protein, gross and metabolic energy. Research methods. System analysis, field, laboratory, comparative calculation. Results. Perennial legumes and legume-grass mixtures are the main source of protein for livestock. According to the results of three-year studies, it was found that regardless of the composition of grass mixtures in the tri-grass regime of grass use, the content of crude protein in the dry weight of feed was much higher compared to the two-grass regime of grass use. And a high content of crude protein was in the dry mass of the forage from the grass mixture of birdsfoot trefoil with tail grass. So, with a three-time alienation of the yield of the leafy mass of the grass mixture, the birdsfoot trefoil with tail grass, had a high content of crude protein: 13.93 – in the first, 15.83 – in the second and 15.09% – in the third slopes. Replacement of the two-oxide mode of use with trioxide increased the content of exchange energy from the first cut of the grass mixture with birdsfoot trefoil with tail grass by 0.19 MJ/kg of dry matter, and of the grass mixture of birdsfoot trefoil with bromus inermis – by 0.18 MJ/kg of dry matter. Conclusions. Thus, in the triangular mode of use of larch-grass stands, the nutritional value of the feed was higher compared to the two mowings. Thus, with three-time alienation of the crop of leaf mass, the content of feed units was 0.76-0.82, metabolic energy – 8.77-9.15 MJ/kg, while with double mowing – respectively 0.75-0.80 and 8,75-9.03 MJ/kg of dry matter

The article presents the results of studies of the effect of seeding rates and row spacing on the forage productivity of different alfalfa ecotypes when mowing grass in the flowering stage. In the soil-climatic conditions of the right bank forest-steppe irrespective of the effect of abiotic and biotic factors during the growing season, high adaptability of alfalfa of the southern ecotype of the Angelica variety was established, which formed a stable crop of green mass at the optimal seeding rate (8,0 million/ha) and width 12,5 cm. For an average of two years of grass use, the varieties of alfalfa Rosana and Angelica provided a yield of green mass of 62,96-64,02 t/ha, which was 11,1-14,9% higher than for sowing with the norm of sowing 4,0 million/ha, and 6,3-7,1% with row spacing half (25,0 cm). It was found that in two years of use of alfalfa Angelica variety had higher dry matter content, compared with the variety of Rosana and were respectively 23,05 and 22,98%. There was a gradual decrease in the dry matter content with a thickening of the herbage in the Rosana variety from 23,32 to 22,72% and from the Angelica variety from 23,31 to 22,84%. As the row spacing increased from 12,5 to 25,0 cm, the solids content increased by 0,28-0,62%, or 22,74-22,84 and 23,12-23,36%. The crude protein content in the dry matter of alfalfa plants of both varieties differed by slopes and years of herb use. The highest content of crude protein was obtained in the dry matter for sowing with a row spacing of 12,5 cm, which averaged 21,10% in the Rosana variety and 20,23% in the Angelica variety or increased by 0,79-0,87%, compared to the row spacing of 25,0 cm. Thus, irrespective of the hydrothermal conditions during the growing season of the studied varieties of alfalfa sowing Rosana and Angelika, the average yield of dry matter at the level of 13,64-13,93 and 2,76-2,88 t/ha of crude protein at the width of row 12,5 cm.

The results of research on the influence of species composition of grass mixtures, the level of fertilizing, and growth stimulator Fumar on the productivity of sown meadow herbage on typical low-humus chernozems of the Right-Bank Forest-Steppe are presented. The experimental part of the work was performed in the scientific laboratories of the Forage Production, Land Reclamation, and Meteorology Department in the production unit of the National University of Life and Environmental Sciences of Ukraine "Agronomic Research Station". The territory of the research station is located in the Right-Bank Forest-Steppe and is a part of Bila Tserkva agro-soil district. The experimental plots were laid on typical low-humus chernozems, coarse-grained light loam in terms of mechanical composition, which are characterized by a high content of gross and mobile forms of nutrients. The climate of the region is characterized by unstable humidity and moderate temperatures. The average annual air temperature is 6-8 ° C. The annual amount of precipitation reaches 562 mm, during the growing season - 354-394 mm (63-70% of the annual norm), which falls unevenly throughout the year. The purpose of the study is to establish patterns of high productivity formation of sown perennial grasses depending on the species composition and fertilizers on typical low-humus chernozems of Right-Bank Forest-Steppe. The analysis of fertilizers effect showed that the highest productivity on all stands was provided by the combined application of complete mineral fertilizer and biostimulator of growth Fumar (N60P60K90 + Fumar), where productivity compared to the option without fertilizer on average over the years of research on alfalfa t/ha of dry mass or by 9%, on its mixtures with cereals - by 0.89–1.19 t/ha, or by 9–11%, and on cereal herbages - by 2.79 t/ha, or by 54% at LSD 0.41 t/ha. Productivity from the use of growth stimulant Fumar increased by 0.27-0.32 t/ha of dry weight or 2-4% and depended a little on the species composition of herbages. High efficiency of alfalfa inclusion in leguminous-cereal grass mixtures, as well as use of single-species alfalfa sowing for fodder purposes, especially on backgrounds without mineral nitrogen, was revealed. The productivity of these herbages in comparison with cereal herbages on nitrogen-free backgrounds (variants without fertilizers and P60K90) on average for 2014–2016 increased from 3.74–4.10 to 8.06–8.68 t/ha of fodder units, from 0.57-0.66 to 1.70-1.96 of crude protein, from 93.7-101.4 to 182.1-206.2 GJ/ha of gross energy and from 38.9-42.7 to 82.4–91.3 GJ/ha of metabolic energy or by1.8–3.0 times, while on backgrounds with nitrogen application (variants N60P60K90 and N60P60K90 + Fumar) - respectively from 5.73–5.93 to 8, 27–9.22 t/ha, from 1.13–1.21 to 1.89–2.29 t/ha, from 139.8–144.8 to 192.5–219.1 GJ/ha, and from 59.6–61.7 to 89.4–98.2 GJ/ha, or by 1.4–1.6 times. Comparison of the productivity of alfalfa-cereal mixtures with single-species sowing of alfalfa shows that on the same backgrounds it was at the same level with slight fluctuations. On average, in the first three years of use, the most influential factor in the yield of 1 ha of dry mass is the factor of grass cover with a share of 60%. The share of fertilizer factor is 40%. The inclusion of alfalfa in legumes and cereal mixtures, as well as the use of single-species sowing for fodder purposes compared to cereals in the background without mineral nitrogen on average for the first three years of use, increases the productivity of sown grasslands from 5.12-5.54 to 10,44–10.78 t/ha of dry weight, from 3.74–4.10 to 8.06–8.68 t/ha of feed units, from 0.57–0.66 to 1.70 1.96 of crude protein and from 38.9–42.7 to 82.4–91.3 GJ/ha of exchange energy or by 1.8–3.0 times, while on backgrounds with N60 application - from 7.28–7.59, respectively, to 9.42–9.71 t/ha, from 5.73–5.93 to 8.27–9.22 t/ha, from 1.13–1.21 to 1.89–2.29 t/ha and from 59.6–61.7 to 89.4–98.2 GJ/ha, or only by 1.4–1.6 times. Among the alfalfa-cereal herbages in the first two years of use, the most productive was the agrocenosis, the cereal part of which is represented by smooth bromegrass and English bluegrass. The lowest, but quite high productivity of alfalfa and alfalfa-grass herbages is provided without fertilizers, which on average for the first three years of use ranges from 9.95 to 10.86 t/ha of dry weight, 1.70 to 1.85 t/ha of crude protein, 82.4–85.8 GJ/ha of metabolic energy, while cereals, respectively, 5.12 t/ha, 3.74 t/ha, 0.57 t/ha, 38.9 GJ/ha.

The right and appropriate system of receiving and transferring goods is needed by the company. In the process of receiving and transferring goods from the central warehouse to the branch warehouse at PDAM Tirta Kerta Raharja, Tangerang Regency, which is currently done manually is still ineffective and inaccurate because the Head of Subdivision uses receipt documents, namely PPBP and mutation of goods, namely MPPW in the form of paper as a submission media. The Head of Subdivision enters the data of receipt and mutation of goods manually and requires a relatively long time because at the time of demand for the transfer of goods the Head of Subdivision must check the inventory of goods in the central warehouse first. Therefore, it is necessary to hold a design of information systems for the receipt and transfer of goods from the central warehouse to a web-based branch warehouse that is already database so that it is more effective, efficient and accurate. With the web-based system of receiving and transferring goods that are already datatabed, it can facilitate the Head of Subdivision in inputing data on the receipt and transfer of goods and control of stock inventory so that the Sub Head of Subdivision can do it periodically to make it more effective, efficient and accurate. The method of data collection is done by observing, interviewing and studying literature from various previous studies, while the system analysis method uses the Waterfall method which aims to solve a problem and uses design methods with visual modeling that is object oriented with UML while programming using PHP and MySQL as a database.
