The aim is to improve the existing technology of growing hybrids and maize line on irrigated lands by studying the impact of new biological products, selection of new high-yielding, plastic hybrids, and other elements of technology under drip irrigation, which will increase grain, seed and economic efficiency. The goal is achieved through the selection and scientific substantiation of the most effective drugs for the respective maturity groups of hybrids and parental lines under drip irrigation, which will increase the yield of maize hybrids through the use of environmentally friendly biologicals. In comparison with the control, the increase in grain yield of maize hybrids from the application of the drug Biospectrum BT was 1.3 t / ha or 9.6%. The increase in yield from the use of the drug Trichopsin BT was 1.2 t / ha or 8.9%, the increase in yield from the use of the drug Fluorescein BT - 1.0 t / ha or 6.7%. Treatment with the biological product Biospectrum BT contributes to the formation of the highest grain yield of the parent forms of corn, which averaged 5.02 t / ha, the yield increase was 0.21 t / ha or 4.18%. Treatment with the biological product Trichopsin BT had a positive effect on the yield, which averaged 4.54 t / ha, providing a yield increase of 0.35 t / ha or 8.4%. Treatment with the biological product Fluorescein BT provided a yield increase of 0.14 t / ha or 3.3%. It was found that the use of biologicals Fluorescein BT, Trichopsin BT, Biospectrum BT reduced the incidence of corn lines with blister smut by 1.9–4.2%. The incidence of fusarium head blight decreased by 2.8–4.0% with the use of these drugs. The incidence of stem (corn) butterfly with the use of Trichopsin BT and Biospectrum BT decreased by 0.9 Product Description popup.authors Zabara Pavlo P Lavrynenko Yurii O Marchenko Tetiana Yu popup.nrat_date 2021-01-02 Close
