EFFECT OF HUMIC ACIDS PRODUCTS ON TOMATO PRODUCTIVITY ON IRRIGATED CHESTNUT SOILS OF THE SARATOV TRANS VOLGA REGION
Keywords:
products based on humic acids, tomatoes, irrigation, dark chestnut soilsAbstract
Studies to determine the efficacy of humic acids products produced by Life Force LLC, were carried out on irrigated dark chestnut soils on the left bank of the Volga river between 2014- 2016. Experiments were carried out on tomato “Novichokkrasny”. It was determined that a single application of K-HumateNa with micronutrients solution (1.0 l/ha) for approximately three years increased the yield of marketable tomato by 12%. Foliar application of Reasil® micro Hydro Mix solution (1.0 l/ ha) resulted in a yield increase by 23% towards the control. If to compare with K-Humate-Na with micronutrients, double application of Reasil® micro Amino Cu allowed to obtain the highest yield during the experiments (on average 78.97 tones/ha) and the maximum increase towards the control (on average 33% in three years). If to compare with Reasil® micro Hydro Mix, the most efficient was Reasil® Forte Carb-N-Humic when applied two times (yield increase - 28% towards the control). Products based on humic acids had a positive influence on a content of micronutrients, sugars and vitamin C in tomato fruit. There was stated that the content of nitrates was seven times lower the permissible limits when applied to all groups and during the whole period of experiment.
