Приемы повышения продуктивности нута в Волгоградской области

Abstract

The article presents research materials on the cultivation of the chickpea variety Privo 1 in the zone of chestnut soils of the Volgograd region. In three-year experiments, the effectiveness of growth stimulants and trace elements was studied in the treatment of chickpea seeds before sowing. Factor A - growth stimulants. 1. Control (without growth stimulants); 2. Nano-Gro; 3. HB-101; 4. Rizotorfin. Factor B - trace elements. 1. Control (without trace elements); 2. Ammonium molybdate (Mo-52%); 3. Boric acid (B-17.3%). The highest photosynthetic potential was formed in the variants with seed treatment with the growth stimulator HB-101 and averaged from 1059 thousand m2 x day/ha in the variant without microelements to 1144 thousand m2 x day/ha in the variant with the use of boron. The maximum net productivity in chickpea plants of the Privo 1 variety on average for 2014-2016 was established with a combination of seed treatment with growth stimulator HB-101 and boric acid and was equal to an average of 2.08 g/m2 per day for the growing season. The highest economic yield of chickpeas, on average, according to experience, was established on the combination options during presowing treatment of seeds of the growth stimulator HB-101 with boric acid or ammonium molybdate and was equal to 2.59 t/ha, that is, it was 34.9% higher than in the control variant . The highest percentage of protein in chickpea grain 28.8% was found in the variant of the combined use of the growth stimulator HB-101 with ammonium molybdate. The highest protein yield was observed on variants of the combination of the growth stimulator HB-101 with ammonium molybdate and boric acid, and was equal to 742 kg/ha. The lowest protein yield was in the control variant without the use of growth stimulants and microelements and was equal to 541 kg/ha.
