Influence of plant development stimulating bacteria (PGPB) applications on development, production and production facilities in bread wheat (Dinç)

His study was applied to the grafted bread wheat seeds prepared in Siirt University, Faculty of Agriculture, Field Crops Department Laboratories in 2019-2020, in the parcel no. 108/8 in Masrdin Artuklu District, Çıplaktepe neighborhood, according to the randomized blocks trial design with 3 replications and 24 parcels. Bacillus megaterium TV61C (nitrogen-fixing), Pseudomonas agarici TV24C (nitrogen-fixing), Brevibacillus choshinensis TV53D (nitrogen-fixing-phosphate-solving), Arthrobacter globigormis TV126C (nitrogen-fixing) and Serretia grimesii TV62D (nitrogen-fixing) bacteria for Dinç bread wheat it was aimed to determine the effects on the development of the cultivar. Plant height (cm), spike height (cm), number of siblings (piece), number of spikes per square meter (piece/m 2 ), number of spikes per spike (piece/spike), number of grains per spike (piece/spike), weight of thousand grains (gram), grain yield (kg/da), biological yield (kg/da), hectoliter weight (kg/ 100 l), ten ear weight (gram), protein content (%), sedimentation (ml), wet gluten content (%) and harvest index (%) were determined. In the study carried out; with the applications made in the Dinç bread wheat variety, the plant height is 49,63-57,80 cm, the ear length is 6,06-7,70 cm, the number of siblings is 2,50-3,10, the number of ears is 59,66-79,66 per square meter/m 2 , the number of spikelets pers pike is 13,86-17,23 pieces/spike, the number of grains per spike is 16,56-47,23 pieces/spike, the weight of a thousand grains is 30,91-33,25 grams the grain yield is 273,636-437,192 kg/da also, ,its biological yield is 837,2-1332,0 kg/da, its hectoliter weight is 79,36-83,36 (kg/100 l), its ten ear weight is 16,30-23,16 grams, protein content (%) 13,10-14,16, sedimentation (ml) 49,06-58,23, wet gluten ratio (%) 32,30-34,63 and harvest index (%)26,9506-34,6627 changed between. As a result, the lowest grain yield in Dinç bread wheat variety was 273,636 kg/da, with Brevibacillus choshinensis TV53D (B3: nitrogen-fixing-phosphate solvent). It is used as microbial fertilizer material since 437,192 kg/da inoculated with Serretia grimesii TV62D (B5: nitrogen fixer) and 397,711 kg/da Bacillus megaterium TV61C (B1: nitrogen fixer) were obtained and these two bacteria applications significantly increased the grain yield. It is thought to be an alternative to chemical fertilization.
