The influence of foliar fertilization on the productiv of Cyamopsis tetragonoloba (L.) Taub. cultivated on ordinary chernozem

At present, work is underway in Russia to expand the species diversity of plants, to provide processing enterprises of the light and food industries with domestic raw materials. The purpose of the research is to study the effect of complex mineral fertilizers containing trace elements on the yield of guar grain. The studies were carried out in the soil and climatic conditions of the Lower Don on ordinary chernozem. On average for 3 years the highest yield of 156.0 g / m 2 was obtained when applied fractionally, in three terms (in the phases: steming, budding, fruit formation) of complex fertilizer Ecogrinvit legumes in an amount of 6 l / ha (2 l / ha for one feeding) with a consumption rate working solution of 200 l / ha (for one treatment). The effect of fertilizers was 183.6%. Trace elements copper, boron and molybdenum contained in the studied complex fertilizers and applied fractionally to vegetating guar plants act not only as nutrients and as elements protecting plants from pathogens.
