The effect of humic growth stimulants on the productivity of chickpea (Cicer arietinum L.) varieties

Abstract

In organic farming, the use of plant growth biostimulants in crop cultivation technologies, including chickpea, has become widespread. The purpose of this study: to investigate the manifestation of productivity elements and the yield of chickpea varieties depending on the treatment with an organic growth stimulator. The study employed the following methods: field – to determine the level of yield, laboratory – to investigate the elements of productivity of chickpea, and statistical – to assess the reliability of experimental studies. By treatment options, the complex application of the product during presowing seed treatment and foliar feeding of plants during the growing season was distinguished. The effect of organic growth stimulant on the increase of productivity elements of chickpea in this variant of the experiment was noted by an average of 10.0%. The greatest effect of the preparation was found in the complex treatment of seeds and plants of common chickpea in terms of seed weight per plant (24.0%). They were identified by the influence of varietal properties on the productivity elements of common chickpea varieties Triumf and Pamiat. The Pamiat variety with the seed treatment + foliar dressing variant was the best in terms of chickpea yield, but the Triumf variety had the greatest effect of the growth stimulator on the yield increase. Close correlations were found between seed weight per plant and thousand-kernel weight, number of beans per plant and number of seeds per plant, and yield with plant productivity and thousand-kernel weight. The findings of the study are recommended to be used to adjust the elements of chickpea cultivation technology to increase productivity in production conditions
