Fidelik Harcına Uygulanan Bazı Bitki Besin Elementlerinin Fide Kalitesi Üzerine Etkileri

Bu çalışma 2019 yılında Ege Üniversitesi Ziraat Fakültesi Tarla Bitkileri Bölümü fideliğinde fidelik harcına uygulanan farklı bitki besin elementlerinin fide kalitesi üzerine etkilerini belirlemek amacıyla yürütülmüştür. İzmir-Özbaş tütün çeşidinin kullanıldığı araştırma Tesadüf parselleri deneme desenine göre 3 tekerrürlü olarak yürütülmüştür. Çalışmada, fide boyu (cm), yaprak sayısı (adet/bitki), gövde çapı (mm), fide sayısı (adet/$m^2$), kök uzunluğu (cm), yaş gövde ve kök ağırlığı (g/bitki), kuru gövde ve kök ağırlığı (g/bitki) gibi özellikler incelenmiştir. Araştırma sonuçlarına göre, en uzun fide boyu 20.5 cm, en geniş gövde çapı 4.1 mm ile K2 (400 g/parsel) potasyum dozunda bulunmuştur. Yaprak sayısı 7.8-8.4 adet/bitki, fide sayısı, 2.1-3.3 adet/m2 ve kök uzunluğu 2.6-2.8 cm aralığında saptanmıştır. Sonuçlar dikkate alındığında uygulanan potasyum dozu ile fide boyu, gövde çapı ve kök uzunluğu artmıştır.

Effects of Some Plant Nutrients Applied to Seedbed Compost on Seedling Quality

This study was carried out to determine the effects of some plant nutrients applied to seedbed compost on seedling quality in 2019 inthe seedbed of Ege University, Faculty of Agriculture, Department of Field Crops, in Turkey. In the trial Izmir-Ozbas tobacco varietywas used and experimental design was randomized complete parcel design with three replications. In the study, lenght of the seedling(cm), number of the leaf (per/plant), stem diameter (mm), healthy seedlings per square (pcs/m2), lenght of the root (cm), fresh stemand root weight (g/plant), dry stem and root weight (g/plant) were evaluated. According to the results, the longest lenght of seedlingand stem diameter was found in K2 doses (potassium doses: 400 g/parcel) as 20.5 cm and 4.1 mm, respectively. Besides, number ofthe leaf, healthy seedling per square and lenght of the root were 7.8-8.4 per/plant, 2.1-3.3 pcs/$m^2$, 2.6-2.8 cm, respectively.Considering the results, as the amount of potassium applied increased, the amount of length of the seedling, stem diameter andlength of the root increased as well.
