ABSTRACT

The effect of different doses and time of boron fertilization on growth and development of grape plants were studied on the soils of Terek-Kumskiy sands of Chechen Republic, Russian Federation. The aim of research is to study the content of boron in the soil and to identify the physiological response of the vine plants on boron fertilizer. The obtained data of the boron total content in the studied sandy soil showed that in 0-60 cm layer of the soil the boron total content ranges from 0.4 to 0.5 mg/kg, in 60-150 cm soil layer - from 0.75 to 0,78 mg/kg. The boron content in the sandy soils of studied area varies within wide limits and characterizes as insufficient. Fertilizing with boron is an effective agricultural technique and allows to increase the sugar content of the berries up to 0.8-1 4 g/cm3, while substantially reducing the acidity of the juice. The yield of grape crystal grade in the variant with background + N90 P90 K90 + 2 kg of active boron addition was 76.8 t/ha, which is higher than in the control at 34.2 t/ha. The increasing of sugar berries in this variant was from 0.8 up to 1.4 g/cm3. The highest rates for plants productivity were observed by application of complex of boron micronutrients, cobalt, manganese, molybdenum, zinc in the form VIII, wherein the yield totally was 89.4 c/ha. The developed technique for sandy soils fertilization allows to increase a quality of grapes, their properties also allow to improve costs of produced grape material.
