PRODUCTION TESTS OF FOLIAR FEEDING OF SUNFLOWER ON THE BLACK SOIL OF ORDINARY NORTHERN KAZAKHSTAN

The effectiveness of Valagro's sunflower nutrition system (liquid mineral fertilizers and plant growth regulators) on seed yield and quality in the production conditions of the forest-steppe zone of Northern Kazakhstan has been studied. A production field experiment was conducted in 2023 in the North Kazakhstan region on crops of a hybrid of Neoam on ordinary chernozem. The Valagro nutrition system has shown its effectiveness and expediency of application on such a high-margin crop as sunflower in the conditions of ordinary chernozems of Northern Kazakhstan. It included the use of drugs: Megafol, Yieldon, Plantafol 10-54-10, Plantafol 30-10-10, BrexilMix, Boroplus. Its use in production tests provided an increase in yield of 18% (0.6 tons / ha, with a yield without preparations of 3.2 t / ha), as well as quality indicators. The net profit amounted to 63,000 tenge/ha.
