Abstract
Successful vineyard production requires consideration of farmer and vineyard attributes as well as management practices. However, none of the previous studies evaluated these factors together for their effects on grape yield and economic performance. Conducted in the Dicle district of the Diyarbakır province of Türkiye, this study aimed to address this gap. Study data were collected using structured questionnaires from vineyard farms in 2018. Demographic variables, vineyard attributes, viticultural practices, and grape processing were examined regarding their effects on the success of viticulture. Descriptive statistical methods and logistic regression models were used in the data analysis. The study revealed that labor force, geographic aspects, hoeing, fertilization, irrigation, and processing significantly affected the success of viticulture in the study area regarding both grape yield and the gross margin of viticulture. Another striking result was that plant protection practices did not yield positive significant effects on the success of viticulture despite the well-known and top-ranking farmer complaints about vineyard pests and diseases. A negative and insignificant effect of fertilization on gross margin despite its positive and significant effect (P < 0.05) on grape yield implies cost-ineffective fertilization. It was concluded that considerably low yielding and overaged vineyards should be rejuvenated, and farmers should be trained in management practices. Moreover, old but still productive vineyards of the region can be turned into opportunities by registering them as heritage vineyards, and the products made from their grapes should be certified and supported by the geographical indication to verify their authenticity.

Notes
Grape juice thickened by boiling.
A sweet, dried thin layer of pudding-like slurry made of flour and boiled grape juice.
Weeds are reported to be an important problem in vineyards, and the problematic ones are generally cosmopolite species in Diyarbakır (Kaçar and Özaslan 2020).
