Effect of chelate fertilizers on the yield of potato minitubers in greenhouses

The results of the three-year research on growing seed potato are presented. The research showed that different combinations of chelated fertilizers with microelements, amino acids and sticking agent increased the number of mini tubers of Meteor, Udacha, Red Scarlette, Bryansky delikates and Krasavchik varieties (10.2-56.2 pcs/m²) in comparison with the control. The increased number (30.4-56.2 pcs/m²) of mini tubers of the mentioned varieties was observed after the application of Izagri Phosphorus (0.5 ml/m²) - into the soil before seeding the plants, Izagri Phosphorus (0.3 ml/m²) - during the bud-formation period, Isagri Potassium (0.3 ml/m²) - during the accumulation. Less significant yield (except for Krasavchik variety) was observed after the application of Isagri Phosphorus (0.3 ml/m²) - during the bud-formation period, Isagri Potassium (0.3 ml/m²) - during the accumulation. The application of liquid chelated fertilizers increased the output of 7-60 mm mini tubers. In comparison with the control an increase in the output of mini tubers of Meteor, Udacha, Red Scarlette, Bryansky delikates and Krasavchik varieties was 5.4-50.6 psc/m² depending on the test variant. The output of mini tubers per bush showed the similar regularity. An increase in the number of mini tubers after the application of chelated fertilizers was 0.2-2.8 pcs/bush in comparison with the control. The application of liquid chelated fertilizers increased the mass output of 7-60 mm mini tubers. The weight of one tuber of Udacha variety increased by 2.9-6.9 g depending on the test variant. The other varieties showed a decrease in the weight of one tuber. Thus to increase the potato yield, output of 7-60 mm tubers, it is reasonable to use different combinations of Isagri Phosphorus (0.5 ml/m²) - into the soil before seeding, spraying with Isagri Phosphorus (0.3 ml/m²) - during the budformation period and Isagri Potassium (0.3 ml/m²) - during the accumulation.
