Effect of fertilizer application on the ‘Bukhara-102’ variety of cotton yield in salt-affected cotton fields of Uzbekistan

Abstract

In this article, stratified feeding of Bukhara-102 variety of medium-fiber cotton with mineral fertilizers were carried out in the conditions of irrigated and fertile soils of Kashkadarya province. Simultaneously, compared to the studied fertilizer application options, there was a decrease in soil volume by 0.01–0.02 g/cm3, an increase in soil porosity by 0.4–1.2%, and an increase in soil water permeability to 5.8–24.6 m3/ha. Moreover, an additional yield of 1.3–2.6 quintals of cotton, the quality indicators of fiber length that increased by 0.1–0.2%, fiber yield to 0.2–0.5%, the weight of 1, 000 seeds to 1–2 grams , the incidence of Wilt's disease was found to become as low as 6.1–10 %. At the same time, with increasing salinity in the care of saline soils at different levels, the net profit was around 40, 617 - 1, 127, 853 UZS and the profitability rate was 0.8-20.1% lower than expected.

Efficiency of drip irrigation of almonds and pistachios with snow and rainwater

“…In this study, placement of all field experiments, measurements, observation and calculation were done based on "Methods of conducting field experiments. Furthermore, analysis of the nutrient amount in soil and plants was performed using methodological manual, "Methods of agrochemical and agrophysical research in irrigated cotton areas" [5,6,[8][9][10][11]. Noteworthy, the obtained data on wheat productivity were analyzed mathematically and statistically using the method of dispersion analysis in the manual "Methodology of field experience" by B.A.…”

“…Many scientists have conducted research in this direction, including Kostyakov A.N., Averyanov S.F., Abutaliev F.B., Nerpin S.V., Rode A.A., Skobeltsyn Yu.A., Djavakyants Yu.M., Mirzajanov Q.M., Nurmatov Sh.N., Bezborodov G.A., Dukhovnyy V.A., Hamidov M.Kh., Ikramov R.K., Serikbaev B.S., Isaev S.Kh., Komilov B. .S., Sarimsakov M. [5][6][7][8][9][10][11][12][13][14]. For many years, furrow irrigation methods was used to irrigate crop areas around the world and in Uzbekistan.…”

“…Khudoev I.J. towards development of elements and technologies of water-saving irrigation techniques, and some achievements have been gained [1][2][3][4][5][6][7][8][9][10]. However, there are not enough studies on developing the effect of drip irrigation with snow and rainwater on the productivity of "Pervenets" almond and "Albina" varieties of pistachio, which have been irrigated for a long time, in the dry arid soils of Andijan region.…”

“…However, there are not enough studies on developing the effect of drip irrigation with snow and rainwater on the productivity of "Pervenets" almond and "Albina" varieties of pistachio, which have been irrigated for a long time, in the dry arid soils of Andijan region. Besides, the effect of this drip irrigation method on the water physical properties of almonds and pistachios and on its growth and productivity has not been sufficiently studied yet [1][2][3][7][8][9]. Therefore, this study aims to increase the efficiency of drip irrigation of almonds and pistachios with snow and rainwater in the conditions of arid soils of Andijan region under the conditions of global climate change [5,6,12,13].…”

Cotton drip irrigation using magnetic technology

“…The results of the research show that the magnetization of water in magnetic devices of various designs, during irrigation, leads to an acceleration of seed germination, growth and development of crops, and an increase in yield is up to 26 percentage with a decrease in the specific consumption of irrigation water. The utilization of a magnetic equipment does not necessitate any upkeep, further education, or ongoing energy bills [10].…”
