Investigation of the Effects of Potassium on Some Agronomic Traits in Dry Bean Genotypes
Investigation of the Effects of Potassium on Some Agronomic Traits in Dry Bean Genotypes
This study was carried out to investigate the effects of 5 different doses of potassium (0, 15, 20, 25 and 30 kg da-1) on some yield and important yield components on 6 different dry bean genotypes of bean [Phaseolus vulgaris L.] in Yunak Town – Konya City (TURKIYE) ecological conditions. was made in 2018. The aforementioned research was designed with 3 replications based on "Split Plots in Randomized Blocks Trial Design". According to the results of the research, it has been determined that potassium applications at different doses are statistically significant in terms of emergence time, flowering time, pod setting time, and vegetation period. As a result of the research; the emergence period was 6.33 – 15.67 days, the flowering period 32.00 – 71.67 days, the pod setting time 48.67 – 88.00 days, the vegetation period 84.67 – 118.00 days, the spad value 41.57 – 53.87 spad, number of main branches per plant 2.90 – 5.00, first pod height 9.40 – 18.40 cm, root neck diameter of 4.97 – 31.50 mm, the number of pods per plant varied between 13.30 – 42.00, the number of seeds per pod varied between 3.20 – 5.67 values. When evaluated in general, emergence time, flowering time, pod setting time increased with increasing potassium application, while vegetation time, and first pod height (maximum value at 15 kg da-1 dose) values decreased. In the study, all of the shortest duration values in terms of all phonological observations emerged in the Akkiraz genotype, which was applied at a fertilizer dose of 15 kg da-1 . The highest value for the first pod height was determined in the 25 kg da-1 fertilizer dose X Nirvana genotype, the highest pod number value in the 20 kg da-1 fertilizer dose X Nirvana genotype, the highest seed number value in 15 kg da-1 fertilizer dose X Nirvana genotype. For the consistency of the research findings, it can be said that longer-term studies and evaluation of different genotypes in different ecologies are required.
