The effects of different organic fertilizers and reduced doses of chemical fertilizer applications on yield and quality traits in greenhouse melon cultivation

Abstract

As a result of excessive use of chemical fertilizers in greenhouses, the yield and quality of the crop decreases over time. In the study carried out in two different locations; Arbuscular Mycorrhizal Fascicles (AMF), vermicompost (VC), seaweed (DY), bat manure (YG) and 30% reduced chemical fertilizer (KG) were applied. In the study, fruit length and diameter, fruit weight, fruit meat and Shell thickness, leaf fresh and dry weight, pH and total dry matter dissolved in water were measured. According to the measurements made in both greenhouses; best results in terms of fruit length, fruit diameter, fruit weight, fruit number; Taken from YG+AMF+KG application. YG+AMF+7/10 KG application, where the best efficiency was obtained in Greenhouse-A conditions, showed an increase of 44.8% compared to the control application and 10.4% compared to the KG application. YG+AMF+7/10 KG treatment, in which the best efficiency was achieved in the effect of applications on fruit weight in Greenhouse-B conditions, showed an increase of 41.3% compared to the 12.5% control application compared to the KG. In conclusion; It was determined that mycorrhizal inoculation, some organic fertilizers and 30% reduced chemical fertilizer combinations applied in melon cultivation increased the yield in both lotions more than the full dose chemical fertilizer.
