Abstract
The aim of the study is to determine the effects of minimal pruning (MP) and unpruned&unheaded (UP&UH) on young Fernor walnut cultivar trees concerning, tree growth, yield, nut quality and water use efficiency. The trees in the research orchard were planted in 2017. According to the data, a statistically significant difference was found between (MP) and (UP&UH) in terms of shoot length, canopy length, tree height, yield, kernel weight, kernel ratio and nut length. The two-year cumulative yield value was found to be 6036.28 g in (MP) and 9865.87 g in (UP&UH). The stem water potential values (GSP), (MPa) of (MP) and (UP&UH) were 7.65 and 7.50, respectively. Considering the significant difference in yield between two pruning methods, it has been observed that water use efficiency is higher in (UP&UH). If water deficiency and insufficient fertilization are combined with (UP&UH), significant losses in tree growth, yield and nut quality can occur. In this context, (UP&UH) should be considered along with other factors that will affect tree growth, yield and fruit quality.

Abstract
Çalışmanın amacı, minimum budama (MP) ve budamama&tepe vurmamanın (UP&UH) genç Fernor çeşidi ceviz ağaçlarında ağaç gelişimi, verim, meyve kalitesi ve su kullanım etkinliği üzerine etkilerini belirlemekti. Araştırma bahçesindeki ağaçlar 2017 yılında dikildi. Verilere göre (MP) ile (UP&UH) arasında sürgün uzunluğu, taç uzunluğu, ağaç yüksekliği, verim, iç ağırlığı, iç oranı ve meyve boyunda istatistiksel olarak önemli farklılık bulundu. İki yıllık kümülatif verim değeri (MP) ağaçlarında 6036,28 g, (UP&UH) ağaçlarında 9865,87 g olarak belirlendi. (MP) ve (UP&UH)'nin ortalama gün ortası gövde suyu potansiyeli değerleri (MPa) sırasıyla 7,65 ve 7,50’dır. İki budama yöntemi arasındaki verim farkı dikkate alındığında (MP) uygulamasında su kullanım etkinliğinin daha yüksek olduğu görüldü. Sulama suyu yetersizliği ve yetersiz bitki besleme&gübreleme yönetimi (MP&UH) ile birleştiğinde ağaç gelişiminde, verimde ve meyve kalitesinde önemli kayıplara neden olabilir. Bu bağlamda (MP&UH) uygulaması, ağaç gelişimi, verim ve meyve kalitesini etkileyecek diğer faktörlerle birlikte düşünülmelidir.
