The effect of microbiological fertilizers on grain weight of beans

Abstract

The effect of microbiological fertilizers on Serbian genotypes and on field in Serbia were studied using four microbiological fertilizers and three genotypes of Phaseolis vulgaris. The aim of the experiment was to decrease the costs of crop production and the environmental protection. Microbiological fertilizers originating from the Institute for Soil - Belgrade, the Institute for Field and Vegetable Crops, Novi Sad and two strains are from the Agricultural Faculty in Novi Sad. The researched trait was the grain weight per plant. The analysis of variety and F test showed that there were no significant differences among tested microbiological fertilizers. However, further analysis and LSD test showed that only one fertilizer type, originating from the Agricultural Faculty in Novi Sad had significant effect compared with the control. The highest grain weight was obtained from Biser variety; it was followed by Galeb and Palanacka Rana varieties. There was a significant interaction between microbiological fertilizer and genotype. It was also concluded that cultivar Galeb had the best reaction on all the microbiological fertilizers and that Biser and Palanacka Rana varieties did not have significant effects.
