Study of the effect of the biological product based on Rhizobium lupini nodule bacteria on legumes and cereals

More and more scientific research has been aimed at studying the fixation of “biological nitrogen”, namely microorganisms-symbionts and biological preparations based on them recently. Many years of experiments and production practice clearly show that the microorganisms that fix nitrogen are of greater importance to enrich the soil with nitrogen and increase yields. Rhizobium nodule bacteria, being in symbiosis with bean plants, are absorbed from the atmosphere and supply the plant with the necessary amount of biologically bound nitrogen. Based on these data, the aim of our study is to study the effect of the biological product on the germination, growth and weight of the vegetative mass of legumes and cereals. A comparative analysis of the biological product based on Rhizobium lupini bacteria RL-1 strain with commercial preparations has been carried out. In the experiment the following agricultural crops have been used: peas, wheat, rapeseed, beans. As a result it has been found that RL-1 has a positive effect on the germination, length and mass of vegetative mass of plants. Thus, the length of pea’s offshoots is more by 73 %, rapeseed - by 44 %, wheat -by 60 %, beans - by 12 %. The preparation has also shown a positive effect to the weight of green mass, for example, the weight of peas plants is 50% higher than the controlled ones, rapeseed - by 12 %, wheat-by 90 %, beans - by 14 %. The study relates to the development of microbiological fertilizer plants. As a result of the analysis it was found that the investigated biopreparation based on nodule bacteria R. lupini promotes growth, better germination, increase the green mass of crops.
