Приведены результаты исследований по изучению влияния промышленной технологии возделывания картофеля на развитие, урожайность и качество продукции. Выявлена положительная реакция растений на подкормку K2SO4 в период посадки. Корреляционно-регрессионный анализ урожайности и качества клубней выявил высокую степень достоверности результатов опыта. Содержание нитратов и тяжелых металлов в клубнях было ниже допустимых величин.The results of studies on the impact of industrial technology of potato cultivation on growth, yield and quality of products. There was a positive response of plants to fertilizer K2SO4 in the period of planting. Correlation and regression analysis of yield and quality of tubers revealed a high degree of reliability of the results of experience. The contents of nitrates and heavy metals in tubers was below the permissible values.

TheProduction of biofuel from biomass sources is believed to reduce the reliance of fossil fuel and its cost. This investigation was aimed to produce and characterize the bio-oil obtained from co-pyrolysis. Two different feed stocks were used for co-pyrolysis; one is Mahua seed (MS) and the other one is Polystyrene (PS). The effect in addition of plastic to biomass in pyrolysis process were investigated on the yield and quality of products. Experiments were conducted in a semi-batch pyrolysis reactor under various parameters of temperature, heating rate and blending ratio. The results indicated that a temperature of 525 °C, and blend ratio of 1:1is maximumwith a heating rate of 20 °C/min. The yield of bio-oil obtained from the co-pyrolysis was found to be approximately 71%, which was higher about 22% than that of yield obtained from pyrolysis of Mahua seed (MS) alone. Further the bio-oil was characterized using different spectroscopic and chromatographic analyses. The analysis of the results for characterization of bio-oil indicated that the synergetic effect increased the bio-oil yield and its quality.

Relevance. One of the most important elements of the technology of cultivation of strawberries for increasing productivity and improving the quality of berries is the use of fertilizers that can regulate the growth, development, yield and quality of products.Methods. During 2016-2018, the impact of pre-planting application of complex mineral fertilizers on the yield and quality of strawberries in the Udmurt Republic was studied. The analysis of meteorological conditions during the growing season of the crop according to the research results is carried out.Results. The results of the use of complex fertilizers Azofoska, Perm-yagodnoye and Fusco-yagodnoye on garden strawberries when grown in the conditions of the Udmurt Republic are presented. It was found that the use of these fertilizers in comparison with the control (Azofoska) contributes to an increase in yield and has a positive effect on the quality of berries. The aftereffect of the studied fertilizers on the second and third year of fruiting of wild strawberries is noted. According to the results of research, the highest yield of berries of the garden strawberry was obtained in 2016 in the first year of fruiting when applying Chamfer-berry (1.33 kg/m2 ). The pre-planting application of the FaskoYagodnoye fertilizer provided a reliable increase in yield at all times of berry harvesting, and on average for three years by 0.13 kg/m2 with an NSR of 0.04 kg/m2 . The content of dry matter, water-soluble sugars and vitamin C in the berries corresponded to the characteristics of the Darenka variety and to a greater extent depended on the meteorological conditions of the growing season of strawberries.

Приведены результаты исследований отзывчивости новых сортов картофеля на загущение посадок по урожайности и качеству продукции. Дана экономическая оценка эффективности уплотнения посадок в разных условиях вегетации растений. Рекомендована оптимальная густота стояния для ряда сортов на дерновоподзолистых супесчаных почвах Центрального района Нечерноземья РФ.The article presents the results of research on responsiveness of new potato varieties in the compacting of the landings on the yield and quality of products. Given the economic estimation of efficiency of seal landings in different conditions of vegetation of plants. The optimal density of standing for a number of varieties on sodpodzolic sandy loam soils of the Central region of the nonChernozem region of the Russian Federation is recommended.

Internet of Things (IoT) technology has brought revolution to each and every field of common man's life by making everything smart and intelligent. IoT refers to a network of things which make a self-configuring network. The development of Intelligent Smart Farming IoT based devices is day by day turning the face of agriculture production by not only enhancing it but also making it cost- effective and reducing wastage. The aim / objective of this paper is to propose a Novel Smart IoT based Agriculture Stick assisting farmers in getting Live Data (Temperature, Soil Moisture) for efficient environment monitoring which will enable them to do smart farming and increase their overall yield and quality of products. The Agriculture stick being proposed via this paper is integrated with Arduino Technology, Breadboard mixed with various sensors and live data feed can be obtained online from Thingsspeak.com. The product being proposed is tested on Live Agriculture Fields giving high accuracy over 98% in data feeds

The article shows in 4 links of field rotation on the light-gray medium loamy soil effects of winter rye and lupine on the yield and quality of potato crop, spring wheat and aftereffects on the yield of third crops - barley and fifth crops - potatoes. Narrow-leaved lupine on gray forest soils of the Chuvash Republic in comparison with winter rye is the best precursor for spring wheat and potatoes. This provides not only the reliable increase of productivity of these crops, but also improve the quality of products. The starch fees per unit area also rises. It should be noted an increase of gluten content in grain of spring wheat from 20.2 % to 29.2 %. An aftereffect of narrow-leaved lupine was manifested at the third level cultures-barley and fifth-potato.
