Economic efficiency of application of humic fertilizers in the cultivation of maize hybrids
The results of research on the use of humates in the cultivation of maize hybrids of Hungarian selection in the conditions of ordinary chernozems of the North Kazakhstan region are presented. The purpose of the research is to conduct an economic assessment of technologies for the use of humic fertilizers in the cultivation of various maize hybrids on ordinary Chernozem of the forest-steppe of Northern Kazakhstan. Field experiments were conducted in 2018-2019 at the North Kazakhstan research Institute of agriculture. The highest yield of dry matter of hybrids was formed in the variant 3 l / t + 1.5 l / ha: 8.58 and 9.39 t/ha, respectively, which provided an economic effect.
