Урожайность сортов нута в условиях предгорного Дагестана в зависимости от применяемых агроприемов

Abstract

According to many researchers, chickpea as a drought-resistant crop in arid regions of the country is promising. In the Republic of Dagestan, research aimed at developing elements of the technology of this crop has not been carried out, and therefore, improving the methods of cultivating chickpeas in the Piedmont province of the republic is an urgent task, which has both theoretical and great industrial significance. Experimental data showed that chickpea varieties had the highest indicators of leaf surface area and net productivity of photosynthesis when treated with the Rizotorfin regulator in the case of using an ordinary sowing method with a width of 0.30 m. Vega variety provided sufficiently high data on photosynthetic activity. Thus, the leaf surface area and NPP in this case amounted to 26.7 thousand m2/ha and 3.90 g/m2 day, respectively. On crops with varieties Volgogradsky 10 and Privo 1, these data were lower by 9.9 - 6.0 and 10.5 and 5.1%, respectively. On average, for options with sowing methods and varieties, the maximum yield, at the level of 1.55 t/ha, was noted on plots with the Rizotorfin regulator, which is 11.0% more than the data of the control variant. The analysis of this indicator, depending on the sowing methods, showed that the row sowing method with a width of 0.30 m turned out to be the most appropriate, where the yield was 1.73 t/ha, which is more than the data of row sowing with a width of 0.15 m and wide-row sowing with a width 0.45 m, respectively, by 24.5 and 14.6%. The highest yield was recorded in the variety Vega, in comparison with the varieties Volgogradsky 10 and Privo1, it increased by 30.6 and 15.1%.
