Effect of humic acids products on cucumber productivity on irrigated chestnut soils of the Saratov transvolga region

Abstract

Studies to determine the effect of humic products produced by LIFE FORCE LLC, RPE were carried out on irrigated dark chestnut soils of the Saratov Transvolga region. The yield and fruit quality of cucumber hybrid “Meringo” were studied during the experiment. It was established that a single application of K-Humate-Na with micronutrients solution increased the yield of marketable fruit for approximately three years by 24% towards the control. When there was applied Reasil® micro Hydro Mix, the yield increase reached 36%. The above mentioned treatments combined with double applications of Reasil® Forte Carb-N-Humic or Reasil® Forte Carb-Ca/Mg/B-Amino, allowed to increase fruit yield by 51-52%. The treatment of cucumber with solution of humic acids products promoted an increase in the content of compounds of nitrogen, potassium and content of sugars and vitamin C in fruit. . There was stated that the content of nitrates was five times lower the permissible limits when applied to all groups and during the whole period of experiment.
