چکیده
The current study has been carried out to determine the effect of mineral and organic fertilizers, as well a growth regulator on productivity promising winter durum wheat varieties, under irrigation conditions meadow-chestnut heavy loamy soil in Terek-Sulak subprovince Republic Dagestan. In 2019–2021 there were laid two trials experimental plot. first case, studied four variants fertilizers varieties ‘Krupinka’ (control), ‘Krucha’, ‘Odari’ conditions. There was used ammophos (background), 65 kg/ha a.i. plowing; for plowing + Polydon bio universal, 0.5 l/ha tillering phase earing phase; arable land ammonium nitrate 150 spring universal 65kg/ha tillering. second, three treated before sowing with l/t Sprintalga foliar top dressing phase, comparison control when seeds 10 working liquid disinfectant Maxim KS. conducted shown that largest achieved third variant trial, where grain 8.36 t/ha variety ‘Odari’, ‘Krucha’ second place 7.91 productivity, which 0.27 more than 0.45 less ‘Odari’. use its significant improvement. Seed treatment crops Sprintalgi had positive growth, development, improvement yield. On average, over years research, yield 7.88 t / ha obtained seed crop Sprintalgi. difference treater KS 0.67 0.71 0.79 ‘Krupinka’.
