Bu çalışma Ülkem börülce çeşidinde çinko (Zn) uygulamasının (0, 2.5, 5, 10
mg Zn kg-1
) farklı tuz konsantrasyonlarında (0, 25, 50, 100, 200 mM) bitki gelişimine
etkisini incelemek amacıyla yürütülmüştür. Deneme Ordu Üniversitesi Ziraat
Fakültesi’nde, tesadüf parsellerde faktöriyel deneme desenine göre 3 tekerrürlü olacak
şekilde saksı denemesi olarak kurulmuştur. Tuz dozları bitkilerde ikinci gerçek
yapraklar (ilk bileşik yaprak) çıktığında uygulanmaya başlamıştır. Araştırmada bitki
boyu, yaprakçık sayısı, toprak üstü yaş ağırlık, toprak üstü kuru ağırlık, kök uzunluğu,
kök yaş ağırlığı, kök kuru ağırlığı, nodül sayısı, aktif nodül sayısı, nodül yaş ağırlığı,
nodül kuru ağırlığı, SPAD değeri ve toprak üstü aksamın Zn konsantrasyonu
incelenmiştir. Araştırma sonucunda tuz stresi bitkilerin incelenen tüm parametrelerini
olumsuz etkilemiştir. Tuzun bitkilerde oluşturduğu ilk olumsuz etkiler 25 mM
dozunda gözlemlenmiştir. Tuz yoğunluğunun artmasıyla birlikte bitkilerde
oluşturduğu hasarlar da artmıştır. Bitki boyu bakımından tuz x çinko interaksiyonu
istatistiki olarak önemli bulunmuştur (p<0.001). Tuz dozları ayrı ayrı incelendiğinde
çinko dozlarının, bitkilerin incelenen parametrelerinin çoğunda tuz stresinin olumsuz
etkilerini azalttığı gözlemlenmiştir. Bu sebeple Zn eksikliği olan ve tuz stresi yaşanan
alanlarda Zn’lu gübreleme yapılmasıyla tuzun olumsuz etkileri azaltılabilir,This study was carried out to examine the effect of zinc (Zn) application on
plant growth in Ülkem cowpea cultivar (0, 2.5, 5, 10 mg Zn kg-1
) at different salt
concentrations (0, 25, 50, 100, 200 mM). It was established in Ordu University Faculty
of Agriculture as a 3-replication pot experiment in randomized plots according to
factorial experimental design. Salt doses were applied when the second true leaves
(first compound leaf) appeared in plants. Plant height, number of leaflets, fresh weight
above soil, soil Top dry weight, root length, root wet weight, root dry weight, number
of nodules, active nodule number, nodule wet weight, nodule dry weight, SPAD value
and Zn concentration of the above-ground parts were investigated. As a result of the
research, salt stress adversely affected all the parameters of the plants. The first
negative effects of salt on plants were observed at a dose of 25 mM. has also increased.
Salt x zinc interaction was found to be statistically significant in terms of plant height
(p<0.001). When the salt doses were examined separately, it was observed that the
zinc doses reduced the negative effects of salt stress on most of the investigated
parameters of the plants. For this reason, the negative effects of salt can be reduced by
fertilizing with Zn in areas with Zn deficiency and salt stress
