Farklı Sulama Düzeylerinin Brokoli (Brassica oleracea L.cv. Beaumont ) Bitkisinin Verim ve Kalite Özellikleri Üzerine Etkisi

Bu çalışma, 2015 yılında Çanakkale Onsekiz Mart Üniversitesi Ziraat Fakültesi Dardanos Araştırma ve Uygulama alanında yürütülmüştür. Çanakkale koşullarında yapılan bu çalışmada, tüm sulama konularına 4 günde bir A sınıfı buharlaşma kabından meydana gelen buharlaşma miktarına göre sulama suyu uygulanmıştır. Deneme de 4 farklı sulama düzeyi oluşturulmuştur. Bunlar sırasıyla; bitkiyi su stresine sokmayacak tam sulama (I1.0), ve diğer stres konuları da tam sulama konusunda uygulanan suyun %70'i (I0.7, orta stres) , %30'u ve %0'nın (I0.3 veI0.0 ağır stres) uygulandığı sulama konularıdır. Deneme sonucunda, brokoli (Brassica oleracea L.cv. Beaumont ) bitkisi su ihtiyacının tam karşılandığı sulama konusunda (I1.0 , 361mm) en yüksek verim ve kalite değerlerine ulaşıldığı görülmüştür. Brokoli bitkisinin yetiştirildiği alanda su kısıtının olması durumunda, %30'luk su tasarrufu yapılarak (Idurumunda verim ve özellikle kalitede önemli kayıpların olabileceği belirlenmiştir.

Yield and Quality Compounds of Broccoli (Brassica oleracea L.cv. Beaumont) As Affected by Different Irrigation Levels

The field experiment was carried out at the Dardanos Agricultural Research Station of Canakkale Onsekiz Mart University in 2015, near Dardanelles straits in Canakkale province, Turkey. Irrigation interval (4-day) was fixed for all treatments and evaporation was determined by Class-A pan. In the full treatment (I1.0), water in the root zone was refilled according to the amount of water evaporated from Class-A pan. In the deficit treatments, the water applied was 70% (I0.7), 30% (I0.3) and 0% (I0.0) of full irrigation. It is concluded that broccoli (Brassica oleracea L.cv. Beaumont) gave the highest yield and quality in terms of that water need (I1.0, 361 mm) was fully met. If there is water scarcity in the field where broccoli is cultivated, an economical income from broccoli production can be obtained by saving 30% water or applying water of 253 (I0.7) mm. However, if water stress exceeds more than 30%, the yield and especially the quality of broccoli can be significantly lost.
