THE EFFECT OF PHOSPHORUS AND ZINC DOSES ON YIELD AND YIELD COMPONENTS OF BEANS (PHASEOLUS VULGARIS L.) IN VAN-GEVAS, TURKEY

This research was carried out in Van-Geva$ in 2015 and 2016 with three replications according to the Divided Parcel Trial Design that was divided into random blocks. The experiment involved 2 bean varieties (Aras-98 and Seker-90) x 4 phosphoms dose (0.0, 40.0, 60.0 and 80.0 kg ha(-1)) x 4 zinc dose (0.0, 10.0, 25.0 and 50.0 kg ha(-1)) x 3 repetition = 72 parcels were planned and examined. In the experiment, 4 different phosphoms (P) doses were applied to the subparcels as TSP (P205) fertilizer. and to gold sub-parcels 4 different zinc (Zn) doses were applied as zinc sulfate (ZnS04.7H20) fertilizer. Two bean varieties used in the study on the effect of phosphoms and zinc doses on plant height (cm), the number of pods per plant (units of plant(-1)), number of branches (plant(-1)), seed yield (kg ha(-1)), harvest index (%) and the effect of protein (%) on grain was also investigated. According to the results obtained in 2015 and 2016, the highest grain yield was obtained from Sugar90 beans. In the first year, the highest grain yield was obtained from 3380.00 kg ha(-1) and 40.0 kg ha(-1) phosphoms and 10.0 kg ha(-1) zinc, while in the second year 4250.70 kg ha(-1) was obtained in the same phosphoms and zinc dose. As a result, it has been determined that due to degradation in the phosphoms balance in soil, the efficiency of utilization of zinc in plants affects the yield and quality characteristics.
