Study on the influence of preparations for foliar and soil nutrition in winter oilseed rape

摘要

During the period 2011-2014 at the Institute of Agriculture and Seed Science "Obraztsov Chiflik" - Ruse, the effects of "BIO-ONE" microbiological fertilizer, humic acid and NH4NO3 were tested on growth and productive qualities of one winter oilseed rape hybrid - "Mercury.The trial was conducted under conditions without irrigation and soil type -strongly leached chernozem.To conduct the experiment were used: 25% of the fertilizer norm of NH4NO3; "BIO-ONE" bacterial fertilizer -consisting of living organisms, 100% natural liquid concentrated microbiological product, including two types of microorganisms: aerobic (Azotobacter vinelandii) and anaerobic (Clostridium pasteurianum); Humic acid (from the deposits in New Mexico), composed of 70% humic acid and 30% fulvic acid.The objective of the study was the influence of "BIO-ONE microbiological fertilizer, humic acid and 25%of the fertilizer norm of NH_4N0_3 to be determined in winter oilseed rape under conditions of IASS "Obraztsov Chiflik" - Ruse.Based on the obtained results it was found that nourishment with "BIO-ONE", humic acid and 25% of the fertilizer norm of NH_4NO_3, accelerated plant growth, influenced on the growth rate of the stems and yield.
