Foliar Feeding Effectiveness During White Mustard Cultivation

Abstract

The purpose of the research is increasing the yield of white mustard varieties by using complex liquid fertilizers in Ryazan region. The research was conducted in 2018-2019 on the fields of the experimental agro-technological station of Ryazan state agro-technological University («Agrotechno-Park»). The soil of the experimental site is gray forest. In 2019, the area under oil producing crops in Ryazan region was more than 151 thousand hectares, the mustard sown area amounted to 9.5 thousand hectares.Two experiments were performed in 4-fold replication. Complex liquid fertilizer in both experiment 1 and experiment 2 provided intensive plant growth and increased pho-tosynthesis rates. The largest number of oilseeds in experiment 1 was obtained on the Lucium breed, variant Azotovit 1 l/ha + Phosphatovit 1 l/ha + Rauactive 1 l/ha – 20.5 C/ha, which is higher than in the control by 3.1 C / ha. Chaika – breed was17.4 C/ha and Rapsodia one –18.5 C/ha (on average over the years of research). Experiment 2 was characterized by the maximum increase in yield of the Lucium breed – 13.1 C/ha (on average per 2018-2019) – on the Active Boron one 1 l/ha + Active Zinc 1 l/ha. Studies of 2018-2019, showed that in practice of agriculture in the region in agrocenoses of white mustard can be used complex liquid fertilizer Azotovit, Fosfatami, Reactiv – pro-cessing phase from 2 to 4 true leaves + phase budding (consumption rate 1.0 l/ha) and complex preparations, Zinc Asset and Asset Bor – processing phase of button rosette + the budding phase (consumption rate 1.0 l/ha).
