Determination of the effects of plant growth promoting bacteria (PGPB) and chicken manure applications on yield and yield components in bread wheat

This study was carried out in Siirt University, Faculty of Agriculture, Department of Field Crops Laboratories and in experimental fields between 2018 and 2019, with 3 replications and 45 parcels. In addition to the previously identified Bacillus megaterium TV60D (nitrogen fixation), Stenotrophomonas maltophilia TV14B (phosphate solubilizing) and Pseudomonas putida TV42A (nitrogen fixation, phosphate solubilizing) bacteria, 300 g (60 kg / da) 600 g (120 kg / da), 900 g (180 kg / da) and 1200 g (240 kg / da) of chicken manure and combination of these were evaluated for the effects on yield and yield components on Ceyhan-99 bread wheat cultivar. Plant height (cm), grain yield (kg / da), spike length (cm), number of tillers, ten spike weight (g), number of spikes per square meter, number of spikelets per spike, number of grains per spike, thousand grain weight (g), hectoliter weight (kg / 100 l), biological yield (kg / da) and harvest index (%) were determined. As a result of the study; after the applications on Ceyhan-99 bread wheat cultivar, the plant height varied between 77.60-81.90 cm, spike length varied between 9.08-5.82 cm, the number of tillers varied between 2.90-3.83, the number of spikes per square meter varied between 85.3-101.0, the number of spikelets per spike varied between 15.93-19.43, number of grains per spike varied between 29.9 - 52.97, thousand grain weight varied between 37.86-40.87 gr, grain yield varied between 347.92-522.2 kg / ha, biological yield varied between 782.6-1300.7 kg / da, ten spike weight varied between 20.84-39.85 gr, hectoliter weight varied between 73.20-78.00 kg / 100 l, and harvest index varied between.35-0.45% As a result, the lowest grain yield was obtained on the TV14B (Stenotrophpmonas maltophilia P) + 0 kg/da chicken manure application with 315.3 kg/da, and the highest grain yield was obtained on TV14B (Stenotrophpmonas maltophilia P) + 180 kg/da chicken manure application with 522.0 kg/da; Among the bacterial applications, the highest grain yield was 356.94 kg/da with Pseudomonas putida TV42A application which is a nitrogen fixation and phosphate solubilizing bacteria.
