The Effects of Using Organic and Chemical Fertilizers on Yield and Yield Parameters in Different Pepper ( Capsicum annuum L.) Varieties

In the pepper plant, which has an important place in agricultural production, plant nutrition is important in increasing the yield. Giving the plant nutrients needed by the plant in organic or inorganic form can have different effects on yield. For this reason, this study was carried out at Erciyes University Agricultural Research Center in Turkey, for a total of three years between 2019 and 2021. In this study, the effects of different liquid organic fertilizer and chemical fertilizer application doses on yield and yield parameters of Kapya, Acı Sivri, and Acı Mor pepper cultivars were investigated. For this purpose, 5 different doses of fertilizer were determined as 100% organic, 75% organic—25% chemical, 50% organic—50% chemical, 100% organic—100% chemical and 100% chemical, respectively. Experimental plots were formed from a total of 15 plots with 3 replications according to the randomized blocks trial design. In total fruit yield, positive results were obtained from all three pepper varieties at the application dose of 100% organic—100% chemical fertilizer. In yield parameters, 50% organic—50% chemical fertilizer application dose was effective in fruit length measurements. However, chemical fertilizer was found to be more effective in two types of peppers in fruit width, which is one of the yield parameters. As a result of the study, it was seen that the use of chemical fertilizers (50/50) together with organic fertilizers was effective on yield and yield parameters, considering the varietal differences and soil characteristics.
