The Use of Complex Fertilizers in the Cultivation of Shallot

Abstract

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.
