EFFECT OF NITRATE-CONTAMINATED WATER ON PARSLEY YIELD

Abstract

The article considers the problem of the quality of irrigation water used in the irrigation of crops. The production of food-safe crops is highly dependent on soil characteristics. The purpose of this work is to establish the effect of irrigation water contaminated with nitrates on the yield of parsley. In an experiment on growing in pots with soil (chernozem), the effect of irrigation water taken from natural wells was investigated. At four increasing levels of nitrate in water (16, 77, 184 and 320 mg/l), changes in nitrate content (from 20 to 1970 mg/kg) were found, adequate concentrations of nitrates in water and decreasing with time. The content of sugars and solids were determined in three cuttings. A parallel trend in the concentration of nitrates and the content of pigments in the leaves is shown. The results obtained provide specific recommendations for the safety of parsley products and soil quality control when enriched with nitrates using irrigation water.
