The use of biofertilizer contribution to plant development and yield in greenhouse broccoli cultivation
Abstract
In this study, the effects of chemical fertilizers and fertilizers containing microorganisms on broccoli yield were examined. It is aimed to reduce the amount of chemical fertilizer by using microorganisms. Mundo F1 Broccoli variety was used as plant material. The research was established according to the randomized block trial design with 3 treatments and 3 replications, and 20 plants were used in each replication. Applications: 1. Control: 100% chemical fertilization (U1), 2. Treatment II: 70% chemical fertilization + Microorganisms (U2), 3. Treatment II: 100% chemical fertilization + Microorganisms (U3). The aim of the study is the effects of chemical fertilizers and microorganisms on plant growth and development; To examine the effect of plant height, stem diameter, number of leaves and yield. It was concluded that the number of leaves, plant height and stem diameter generally increased in the plots where microorganisms were applied. When the results were evaluated in terms of yield compared to the control treatment, U2 treatment increased yield by 20% and U1 treatment increased yield by 15%.
