THE NITRATES NUTRITION STATUS ASSESSMENT AND MANAGEMENT OF THE HORTICULTURAL CROPS IN THE STEPPE ZONE OF UKRAINE
Journal Title: ISB-INMA TEH AGRICULTURAL AND MECHANICAL ENGINEERING - Year 2017, Vol 0, Issue 1
Abstract
The main aims were: a) to prepare a database of the determination of nitrate in vegetable and fruit production; b)to identify plants - accumulators of nitrates and determine the number of samples exceeding maximum permissible concentration (MPC); c) to compare trials and doses of artificial nitrogen fertilizers and vermicomposting extract application in the field experiments with some vegetable and fruit plants. The results of the determination of nitrates in vegetables, fruits and berries, which are most often used in the human diet in steppe zone of Ukraine, are presented. Two foliar spraying with vermicomposting extract give the best results for cabbage cultivation then drip fertigation.The best result for pumpkin cultivation was recorded after vermicomposting extract treatment with a dilution of 1:150. The same trend was observed when determining the optimal doses for the greatest number of seeds and lowest NO3 content. The lowest level of nitrate in pepper fruits was determined in trial with vermicomposting extract foliar spraying with a dilution of 1:100. The best dose-effect response for apple tree yield was fixed for trial with vermicomposting extract two time drip fertigation with dilution 1:50.
