Application of O-Rise fertilizer for foliar feeding of corn

Obtaining high yields of corn grain is impossible without applying fertilizers. There is a shortage of organic fertilizers in agriculture. The use of mineral fertilizers for corn, calculated for the planned yield is an economically disadvantageous technique due to their high costs. Replenishment of the range of agrochemicals with new preparations, such as organic and mineral fertilizer O-Rise and growth regulator Zircon requires their study on various crops. In the conditions of the steppe zone of Russia (Lugansk People's Republic) on ordinary chernozem, field studies were conducted to study the effect of organic fertilizer vermicompost, organic and mineral fertilizer O-Rise and growth regulator Zircon on the yield of corn grain and its quality. Vermicompost, 1 t/ha was applied during sowing. Fertilizer O-Rise was used for foliar feeding of corn crops in the phase of 3-5 leaves (2 l/ha) and in the phase of 7-8 leaves (2 l / ha). The growth regulator Zircon, 40 ml/ha was applied in the phase of 3-5 leaves of corn and 40 ml/ha in the phase of 7-8 leaves of corn. As a result of four-year studies, high efficiency of local (near-sowing) application of vermicompost 1 t/ha was established when growing corn for grain. The yield increase was 4.5 c/ha. The effect of foliar treatments with O-Rise fertilizer and Zircon growth regulator was higher and the yield increase was 5.4 and 7.3 c/ha. With the combined effect of two factors: vermicompost and O-Rise fertilizer; vermicompost and Zircon growth regulator, an additional yield of 8.2 and 10.6 c/ha, respectively, was obtained. Grain with a higher protein content of 11.4% was obtained in the Zircon variant, 40 ml/ha in the phase of 3-5 leaves and 40 ml/ha in the phase of 7-8 leaves.
