ABSTRACT: In this article, for the first time applied
in our republic, the results of the effect of nano-micro fertilizers on cotton
plant are given. The results of the study of the effect of microelements on the
leaf area, plant height formation and yield of cotton in the conditions of the
gray soil of the Zarafshan Valley are presented. Currently, the demand for
ecological and safe food is increasing not only in Uzbekistan, but also in the
whole world. The solution to this problem is effective use of land and increasing
the amount of macrofertilizers, and after increasing the yield per unit of
area, the micronutrients in the soil will decrease more, and less attention was
paid to fertilizing with trace elements. This will affect the quality of the
product, as well as the decrease in productivity and salinity of the land.
Therefore, it is necessary to develop environmentally friendly and more
economical approaches that do not harm the environment. The best solution for
this is to reduce micronutrient deficiency in combination with agrotechnical
methods. One of the urgent issues is the development of the technology of
applying macro- and micro-fertilizers in the appropriate proportions,
convenient terms, norms and methods for the cultivation of high-quality cotton
crops under the soil conditions of our republic. The optimal rate of using
microelements had a positive effect on the leaf area and dry mass of cotton
plants. The highest result was observed when N200P140K100 + KUPRUMHITE + NANOSEREBRO kg/ha was applied with mineral fertilizer.
