Nowadays, the trend is towards environmentally friendly and sustainable cultivation methods. One such element is the use of microbiological fertilizers, which reduce the need for mineral fertilizers, decrease soil pollution and do not pollute rivers. In this regard, the purpose of the study is to investigate the effect of seed pretreatment with microbiological fertilizers on the germination energy and germination of lentil seeds. The experimental work was carried out under laboratory conditions at Penza SAU according to the standard method of GOST 12038-84. During the studies, it was found that the germination energy increased from 91.8% in the control to 93.6% in the variants with the application of a complex of microbiological fertilizers Organit N and Organit P. An increase in seed germination capacity of 3.0-5.2 % was observed compared to the control. The highest germination rates were recorded for the samples with the microbiological fertilizers Azotovit + Fosfatovit and Rizobash, which were 95.8 and 95.2 % respectively. After 72 hours from the start of germination, the nutrient consumption of the lentil seeds in the variants with microbiological seed treatment before sowing was 1.7 times higher than in the control variant (seed treatment before sowing with water only). The highest mass of seedlings and roots (0.8 g) was observed in the variant with the application of Biokompozit-korrekt with an increase in the length of the seedlings by 0.3-1.5 cm and the length of the germinal roots by 0.8-1.4 cm. The maximum seedling length of 9.5 cm and root length of 8.7 cm was recorded in the variant with a mixture of microbiological fertilizers Azotovit and Fosfatovit.
Keywords: lentils, bacterial preparations, microbiological fertilizers, germination energy, laboratory germination.
