Sera Marul Yetiştiriciliğinde Mikoriza ve Farklı Dozlarda Kimyasal Gübre Uygulamalarının Verim, Kalite ve Besin İçeriği Üzerine Etkileri

Öz

ArbüskülerMikorizal Mantar(AMF), sera marul yetiştiriciliğinde gıda ve çevre sağlığı açısından risk oluşturan kimyasal gübrelerin aşırı kullanımının azaltılmasında önemli etkilere sahiptir. Denemenin konusu;(AMF) ve beş kimyasal gübre (KG) dozu; kontrol %0(KG), %25(1/4KG), %50(1/2KG), %100(KG), %150(3/2KG) ve %200(2KG) uygulamalarından oluşmuştur. Hasattan sonunda bitkilerde; baş boyu, baş çapı, kök boğazı çapı, baş ağırlığı, yaprak sayısı, yaprak taze ve kuru ağırlığı, suda çözünür kuru madde oranı ve bitki besin maddesi kapsamları ölçülmüştür. Yapılan ölçümlerde; Kontrol, AMF ve AMF+1/4KG uygulamaları önerilen gübre miktarından (KG) daha düşük değerler alırken, AMF+1/2 KG, AMF +3/2 KG ve AMF+2KG uygulamaları KG uygulamasından daha yüksek değerler almışlardır. İstatiksel anlamda aynı önem seviyesinde en yüksek değerlere sahip olan AMF+3/2KG ve AMF+2KG uygulamaları, kontrol uygulamasına göre bitki baş uzunluğunda %23.4, bitki taç çapında %18.1, bitki kök boğazı çapında %9.6, baş ağırlığında %189, kök uzunluğunda %16, yaprak sayısında 23.7, yaprak yaş ve kuru ağırlığında %32-%26.4 oranında artış yapmıştır. Yaprak besin içerikleri, mikorizal etki ile N, P, K, Ca, Mg, Fe, Zn ve Mn’nin kapsamlarında artış meydana gelmiştir. Bu sonuçlara göre; AMF uygulaması ile marulda kimyasal gübre dozlarının belli oranlarda azaltılarak büyüme, verim ve besin içeriğinin iyileştirilebileceği görülmüştür.

Effects of Mycorrhiza and Different Doses of Chemical Fertilizer Applications on Yield, Quality and Nutrient Content in Greenhouse Lettuce Cultivation

Öz

Arbuscular Mycorrhizal Fungi (AMF) play an important role in reducing the excessive use of chemical fertilisers, which pose a risk to food and environmental health in greenhouse lettuce cultivation. The experiment involved AMF and five chemical fertiliser (KG) doses: control 0% (KG), 25% (1/4KG), 50% (1/2KG), 100% (KG), 150% (3/2KG) and 200% (2KG) applications. At harvest time, head length, head diameter, root collar diameter, head weight, leaf number, leaf fresh and dry weight, water soluble dry matter ratio and plant nutrient contents were measured in the plants. In the measurements; Control, AMF and AMF+1/4KG applications obtained lower values than the recommended fertilizer amount (KG), while AMF+1/2 KG, AMF +3/2 KG and AMF+2KG applications obtained higher values than KG application. The AMF+3/2KG and AMF+2KG applications which had the highest values at the same statitstical significance level, increased the following by the following percentages compared to the control application: plant head length by 23.4%, plant crown diameter by 18.1%, plant root collar diameter by 9.6%, head weight by 189%, root length by 16%, leaf number by 23.7 and leaf fresh and dry weight by 32%-26.4%. Leaf nutrient content increased for of N, P, K, Ca, Mg, Fe, Zn and Mn due to the mycorrhizal effect. These results suggest that growth, yield and nutrient content can be improved by reducing chemical fertilizer doses in lettuce at certain rates with AMF application.
