Grain yield and rhizosphere microflora of alternative types of wheat in organic production

Abstract

This study examines the impact of organic growing technologies on the rhizosphere microflora value and grain yield alternative types of wheat. Research is based on three varieties of different alternative types of wheat (Triticum spelta, Triticum compactum and Triticum durum) and one conventional variety of ordinary soft wheat (Triticum vulgare). The experiment was set up on less carbonate-chernozem, according to the random block design with four replicates for each treatment (F-1-microbiological fertilizer, F-2-the combined use of microbiological fertilizer and organic fertilizer, F-0-control (no fertilizer application)). Research results showed that fertilization significantly influenced the increase in the total number of microorganisms to the level of 3.7% and 28%, and the number of Azotobacter to the level of 2.8% and 19.1%, with the proven higher efficiency of mixed application of fertilizers. Analysis of variance of the total number of microorganisms and Azotobacter showed a statistically significant difference between the tested varieties. Grain yield of spelt (4,540 kg ha(-1)) was significantly higher compared to other varieties. The greatest variation in yield in the three-year period was noted for conventional variety ordinary soft wheat. The examined variants of fertilization had a significant effect on increasing grain yield, from the level of 13.9% to 36.4%.
