Efficiency of growth regulators and mineral fertilizers on row crops in the Rostov region |
|
|
The entry into force of national legislation regulating the rules of production of organic products, actualizes the restructuring of traditional systems of fertilization of tilled crops. Obtaining organic products, if necessary, to preserve and increase the productivity of agrocoenosis and the economic efficiency of corn and sunflower production, is possible with the use of modern agrochemicals. In two-year field experiments on ordinary black soil of the Rostov region, the effect of separate and joint application of traditional mineral fertilizers and growth regulators on the productivity of corn and sunflower crops was determined. The results of the experiments allowed us to develop double recommendations. With intensive cultivation technology, the combination of pre-sowing application of 312 kg/ha of azofoska (N50R50K50) and treatment of seeds and vegetating plants with the growth regulator Mizorin increases the productivity of corn and sunflower hybrids by 0.8 and 1.8 t/ha, respectively. If there are insufficient financial resources of agricultural producers or when organizing the production of organic products, it is necessary to limit the treatment of seeds and plants with growth regulators Mizorin on corn and Rostok or Mizorin on sunflower. Such methods provide an increase in the productivity of corn by 0.67 t / ha, sunflower-by 1.16-1.39 t / ha.
