Özet

Experiments were conducted over the experimental fields of Erciyes University with Goyniik 98 dry bean cultivar (Phaseolus vulgaris L.) in randomized blocks split-split plots experimental design with 4 replications during 2015 and 2016 growing seasons. Humic acid (HA) treatments (two applications, 2 kg da(-1)) were placed in main plots, microbial fertilizer (MF) treatments (two applications, phosphate-solubilizing Bacillus pumilus C26) were placed in subplots and phosphate rock (PR) treatments (4 applications, 29.3% P2O5, 0, 7.5, 15 and 22.5 kg da(-1)) were placed in sub-subplots. Plant and soil samples were taken from the experimental plots for the analyses of yield and yield components. HA, MF and PR treatments had different effects on investigated parameters of dry beans. As the average of the years, plant heights, the first pod heights, number of pods per plant, number of seeds per plant, number of seeds per pod, seed yield, harvest index values, biological yields, hundred-seed weights and seed protein ratios varied respectively between 42.95-53.65 cm, 10.16-13.90 cm, 13.85-24.85, 38.64-59.83, 2.36-3.16, 173.8-314.3 kg da(-1), 31.25-39.73%, 274.4-382.0 kg da(-1), 38.92-43.10 g and 22.93-24.94%. The greatest yield was obtained from the greatest phosphate rock dose applied together with humic acid and microbial fertilizer. All treatments significantly increased seed yields as compared to the control group (173.8 kg da(-1)). It was concluded based on present findings that 22.5 kg da(-1) (29.3% P2O5) phosphate rock together with humic acid and microbial fertilizer could be recommended for both organic and conventional dry bean farming.
