The effects of salinity and drought on onion production

Abstract

The importance of abiotic stress factors, depending on the global warming, has been prominently appeared accompany with irregular climate data in recent years. Among them the most effective factors for the onion (Allium cepa L.) production are soil salinity and drought. The onion is most sensitive vegetable in all plants against to soil salinity. In addition, water demand of onion is very critical at certain growing stage. In this owerviev, at the onion production, the effects of salinity and drought have been compiled from various studies.

Tuzluluk ve kuraklığın soğan yetiştiriciliğine etkisi

Öz

Abiyotik stres faktörlerinin önemi, küresel ısınmaya bağlı olarak son yıllarda gözlenen düzensiz iklim verileri ile belirgin şekilde ortaya çıkmaktadır. Bu faktörlerden, soğan (Allium cepa L.) yetiştiriciliği için en önemli olanları, toprak tuzluluğu ve kuraklıktır. Soğan, kültürü yapılan bitkiler içerisinde, toprak tuzluluğuna en hassas olanlardan biridir. Buna ek olarak, yetiştirme döneminin belli aşamalarında, su ihtiyacı oldukça kritik olan bir bitkidir. Bu çalışmada, soğan yetiştiriciliğinde, tuzluluk ve kuraklık koşullarında ortaya çıkan sonuçlar, çeşitli çalışmalardan derlenmiştir.
