The Effects of Sugar Beet Molasses Applications on Root Yield and Sugar Content of Sugar Beet (Beta vulgaris L.)

Öz

The present study was carried out to determine effects of molasses obtained from sugar beet on yield and quality of sugar beet in Isparta, Turkey during 2011 and 2012 crop seasons. Different concentrations of molasses were applied to soil and to plant leaves at different doses (0, 25, 50, 75 and 100 kg/ha) 3 times during the vegetation period. The experiment was setup as factorial design with randomized complete block design with three replications. Molasses applications significantly increased root yield and quality compared to the control. Soil applications were more effective than foliar applications for all parameters studied. Molasses applications at more than 50 kg/ha for soil and foliar applications negatively affected plant and root growth and their effects was more pronounced in the foliar application. Molasses increased root yield by 20.4% in soil applications and by 9.6% in foliar applications compared to control. The highest root yield was obtained in the soil applications at 50 and 75 kg/ha (72.3 and 72.0 t/ha, respectively) and in the foliar applications at the same dose (66.1 t/ha). Sugar content and gross sugar yield significantly increased with molasses treatments by 1.2 % and 2.9 t/ha, respectively compared to control. It was concluded that sugar beet molasses can be used effectively in order to increase sugar beet yield and quality.

Melas Uygulamalarının Şeker Pancarında (Beta vulgaris L.) Kök Verimi ve Şeker Oranı Üzerine Etkilerinin Belirlenmesi

Öz

Bu araştırma şeker pancarı yan ürünü olarak üretilen melasın şeker pancarında kök verimi ve kalitesi üzerine etkilerini belirlemek amacıyla 2011-2012 yıllarında Isparta ekolojik koşullarında yürütülmüştür. Melasın farklı konsantrasyonları (0, 25, 50, 75 ve100 kg/ha) vejetasyon dönemi boyunca 3 kez toprağa ve bitki yapraklarına uygulanmıştır. Çalışma Tesadüf Blokları Deneme Planında Faktöriyel Düzenlemeye göre 3 tekerrürlü olarak kurulmuştur. Melas uygulamaları şeker pancarında kök verimi ve kalitesini kontrole göre önemli derecede arttırmıştır. Araştırmada incelenen tüm parametrelerde de melasın topraktan uygulanması yaprak uygulamalarına göre daha etkili bulunmuştur. 50 kg/ha’dan daha yüksek dozlarda yapılan melas uygulamaları bitki ve kök gelişimini olumsuz yönde etkilemiş, bu etki yaprak uygulamalarında daha belirgin olmuştur. Kontrol ile karşılaştırıldığında şeker pancarında kök verimi topraktan yapılan uygulamalarda % 20.4, yapraktan yapılan uygulamalarda ise % 9.6 daha yüksek olmuştur. Araştırmada en yüksek kök verimi topraktan yapılan melas uygulamalarında 50 ve 75 kg/ha (sırası ile 72.3 ve 72.0 t/ha) dozlarında, yapraktan yapılan uygulamalarda ise 50 kg/ha (66.1 t/ha) dozundan elde edilmiştir. Kontrol ile karşılaştırıldığında polar şeker oranı (% 1.2) ve polar şeker verimi (2.9 t/ha) melas uygulamaları ile birlikte önemli seviyede artış göstermiştir. Çalışmada melasın şeker pancarında kök verimi ve kalitenin arttırılmasında etkili bir şekilde kullanılabileceği sonucuna varılmıştır.
