In agriculture, the use of microbiological fertilizers is becoming more and more widespread. The presence of microorganisms in them allows improving soil fertility, increasing the productivity of crops, while ensuring the cultivation of environmentally friendly products. There is a wide variety of microbiological fertilizers, so determining the type of preparation for garden strawberries when grown in the conditions of the Udmurt Republic is relevant. The purpose of the research: a comparative assessment of the effect of various types of microbiological fertilizers on the productivity of garden strawberries. Materials and Methods. Studies on the effect of microbiological fertilizers on the yield and its structure of garden strawberries were carried out on the territory of Vostochny LLC, Zavyalovsky District, Udmurt Republic. In 2016, 2018 studies were carried out on the feeding of garden strawberries of the Darenka variety of the first and third years of fruiting with microbiological fertilizers on soddy-medium-podzolic medium-loamy soil. The scheme of the experiment included the following options: Water (control), Baikal EM 1, Emix, Humat EM. The total area of the plot is 2,9 m 2 . The accounting area of the plot is 1,8 m 2 . Placement of variants by a systematic method, in six-fold repetition. Results. Harvesting was carried out in five terms. Studies have proven the positive effect of the studied microbiological fertilizers on plant productivity. The highest yield of berries was 833,6 g/m 2 , which was obtained using Baikal EM 1. The largest berry was obtained in 2016, also when treated with Baikal EM 1, and amounted to 145 g. lo to increase the number of berries from the bush. So, in 2016 their number was 45,2; in 2018 -42,0 pieces.

The results of research on improving the elements of shallot technology are presented. The research was carried out in 2016-2017 in Italmas village of Zavyalovsky district of the Udmurt Republic. Purpose of research: comparative assessment of the productivity of shallot depending on the planting material and fertilizing with complex mineral fertilizers. The tasks of the research were to study the effect of complex fertilizers and planting material of shallot on yield and its structure; to determine the quality indicators of turnips. To study the effect of complex fertilizers on the performance of shallot biochemical studies of bulbs were conducted (dry matter content, nitrates, vitamin C and water-soluble sugars), taking into account the yield and its structure. The highest yield of 32.9 t/ha was obtained by planting shallots with a whole onion and with fertilizing with the complex solution "Rastvorin". When planting shallots with a whole onion, the yield of marketable products was 91.8 %. The bulbs accumulated vitamin C in the range of 5.6-6.8 mg/100 g. The conducted researches have scientific and practical significance.

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.
