| description | The article presents the results of studies on the effect of foliage treatment of crops with solutions of complex fertilizers Azosol 36 Extra and Aquarin 5 with micro-elements in chelate form on the structural elements and grain productuvity of early ripening and medium early maize hybrids at various levels of root nutrition. In the variants without mineral fertilizers, after applying complex fertilizers in the 5-leaf phase, the number of grains on a cob increased by 7.0-9.0%, and after double treatment – by 8.0-9.9%, and there is no big difference in hybrids notably. On the fertilized soil, the treatment of crops in the 5-leaf phase of corn with micronutrient fertilizers allowed to increase the number of grains on a cob of the early ripening hybrid Ladozhskiy 191 MB by 7.2-7.5%, and a double application increased the number of grains on a cob by 7.8-8.1 % When treating the crops of the mid-early hybrid Azosol 36 Extra, the growth of full-fledged grains amounted to 3.0-3.9%, and a greater number of grains were formed when microfertilizers were applied in the 5-leaf phase. Aquarin 5 contributed to an increase in the number of grains on a cob by 4.5-5.6%, and the best results were obtained with its double use. After foliar treatment of early ripening hybrid crops with complex microelement fertilizers in the variants without solid mineral fertilizer, the weight of corn cobs increased by 6.4-11.1% with a slight advantage of using Aquarin 5. The use of Azosol 36 Extra on the crops of the Ronaldinio hybrid in a natural soil made it possible to increase the weight of grain from the cobs by 8.3-9.7%, treatment with Aquarin 5 – by 11.1-13.2%, with large increases obtained after the double use of chelated fertilizer. The binary use of Azosol 36 Extra on the crops of the early ripening Ladozhskiy hybrid 191 MV under conditions of improved root nutrition contributed to an additional 8.2% of grain from a cob. Treatment in the 5-leaf phase and the double use of Aquarin 5 increased the weight of the grain of one cob by 8.6-8.7%. In the crops of the mid-early hybrid, the advantage was also for the Aquarin 5 microfertilizer. Its use in the 5-leaf phase increased the weight of a cob grain by 9.1%, and its double use by 10.1%. Azosol 36 Extra provided smaller grain increments – 5.2-6.2%, moreover, the difference in treatment time was not significant. A promising way to increase the productivity of corn grain is to use complex fertilizer with microelements in the chelate form Aquarin 5 in the 5-leaf phase and double foliar treatment, which contributes to an increase in grain harvest from a unit area on an unapproved agricultural background by 9.6-12.4%, and with the improvement of root nutrition conditions – by 7.7-8.8%. |
