Abstract:

The study was conducted to determine the morphological changes caused by different fertilizer applications on the fresh bean, in the Göllü Village of Tusba District of Van Province according to the randomized blocks experimental design in 2019 and 2020. Sazova 1949 dwarf bean variety was used as plant material in the study. The field experiment was carried out with 4 replications and 4 different fertilizer applications (chemical, organomineral, cattle, and vermicompost) except for the control. In the study, plant height, stem diameter, node number, internode length, flower bud length, flower bud width, flower stem length, number of flowers per cluster, bract length, number of nodes with the first flower, middle leaflet length, number of leaves, first pod height, pod length, pod width, number of pods per bunch, pod weight, pod thickness, number of seeds per pod, chlorophyll (SPAD value) and leaf color L*, a*, b, Chroma°, and hue° values were investigated. As a result of the study; it was determined that different fertilizer applications gave significantly different results in terms of the traits examined, higher results were obtained from organomineral and vermicompost fertilizers compared to the control group, and generally equivalent or better results were obtained than chemical fertilizers. It was concluded that some organic fertilizer applications in bean cultivation might be used as an alternative to chemical fertilizer applications in terms of a sustainable world.
