Abstract

Melon (Cucumis melo L.) is one of the important species of Cucurbitaceae family and commonly cultivated in many parts of the world with the economic importance. This species have very rich variations. Honeydew (var. inodorus) which is within the Muskmelon group is one of them. This study was conducted to evaluate the effect of organic and inorganic fertilizers sources on yield and quality performance of six different varieties of honeydew melon (‘Spring Dew’, ‘Dew Summer’, ‘Fall Dew’, ‘Honey Pearl’, ‘Honey Orange’, ‘Snow Leopard’). For this purpose, greenhouse grown seedlings were planted in the open field with randomized block design with two treatments and four replications. Prior to planting which is divided into strips were applied 15 kg/ha nitrogen from two different sources; organic nitrogen (manure) and inorganic (ammonium sulphate) fertilizer. Result of the study exhibited that fertilizer sources were displayed different responses on the plants. Treatment and cultivar interaction was not significant according to analysis of variance. In addition, there was no effect of the application on the parameters studied. However, cultivars were significantly yield and quality parameters. TSS content was ranged between 13.7 to 10.8%. The highest phenolic content was observed in ‘Honey Pearl’ (291.3 µg GAE/g) and ‘Spring Dew’ (368.7 µg GAE/g). Variety of ‘Honey Orange’ that has light orange flesh color had the highest content of TEAC and FRAP values, while same variety had the lowest phenolic content among the varieties. The results of present study show that fertilizer sources have no significant effect on yield and quality of honeydew. In this case, considering the environmental pollution, plant and human health issues, using manure for honeydew production could be beneficial.

Honeydew Yetiştiriciliğinde Organik ve İnorganik Gübre Kaynaklarının Fitokimyasal Değişimler Üzerine Etkisi

Abstract

Kavun (Cucumis melo L.) dünyanın birçok bölgesinde yaygın bir şekilde yetiştiriciliği yapılan ve Cucurbitaceae familyasının ekonomik öneme sahip türlerinden biridir. Çok zengin bir varyasyona sahip olan bu tür içerisinde bulunan Honeydew (var. inodorus) tipi kavunlar Muskmelon grubu içerisinde yer almaktadır. Bu çalışma da, altı farklı honeydew kavun çeşidinin (‘Spring Dew’, ‘Summer Dew’, ‘Fall Dew’, ‘Honey Pearl’, ‘Honey Orange’, ‘Snow Leopard’) organik ve inorganik gübre kullanımı sonucunda göstermiş oldukları verim ve kalite performanslarına bakılmıştır. Bu amaçla serada yetiştirilen fideler iki farklı uygulama ve her uygulamada dört yinelemeli olarak tesadüf blokları deneme desenine göre araziye dikilmiştir. Şeritlere bölünmüş olan araziye dikim öncesinde 150 kg/ha azot olacak şekilde organik (çiftlik gübresi) ve inorganik (amonyum sülfat) gübreleme yapılmıştır. Sonuçlar, çeşitlerin gübre kaynaklarına göstermiş oldukları tepkilerin farklı olduğunu göstermiştir. Varyans analiz tablolarına göre uygulama x çeşit interaksiyonunun önemli olmadığı görülmüştür. Buna ek olarak uygulamaların da incelenen parametreler üzerinde genellikle önemli bir etki yapmadığı gözlenmiştir. Çeşitlerin parametrelere etkisi istatistiki önemli bulunmuştur. Çeşitlerin SÇKM değerleri 10,8 ile 13,7 arasında değişmiştir. Fenolik içeriği 291,3 µg/g ile ‘Honey Pearl’ ve 368,7 µg/g ile ‘Spring Dew’ çeşidinde en yüksek değerleri vermiştir. Meyve eti açık turuncu ‘Honey Orange’ çeşidinin TEAC ve FRAP değerleri en yüksek çeşitler arasında yer alırken fenolik içeriği en düşük çeşitler arasında yer almıştır. Sonuçlar, organik ve inorganik kökenli gübre kaynaklarının verim ve kalite üzerine belirgin etkilerinin olmadığını göstermiştir. Bu durumda çevre kirliliği, toprak ve insan sağlığı göz önüne alındığında yetiştiricilikte çiftlik gübresi kullanım potansiyelinin yüksek olduğu gözlenmektedir.
