Determination of Yield and Some Plant Characteristics with Vitamin C, Protein and Mineral Material Content in Mibuna (Brassica rapa var. Nipposinica) and Mizuna (Brassica rapa var. Japonica) Grown in Fall and Spring Sowing Times

Öz

This study was conducted in unheated UV – PE greenhouse in 2010 – 2011 using fall and spring sowing times in order to determine yield and some plant characteristics; with vitamin C, protein and mineral material content in mibuna and mizuna. At the end of the study, it was found that mibuna and mizuna were affected by sowing time. Therefore; the spring sowing time, in which mibuna had a yield of 1521.42 kg da-1 and the yield were determined as 1326.56 kg da-1 for mizuna, was determined to be more convenient than fall sowing time. In both of these plants; the convenient sowing time is spring sowing time for Vitamin C, Ca, Mg and Mn contents, and fall sowing time is determined to be convenient sowing time for having higher crude protein, N, P, K, Cu, Fe and Zn contents.

İlkbahar ve Sonbahar Ekim Zamanlarında Yetiştirilen Mibuna (Brassica rapa var. Nipposinica) ve Mizuna (Brassica rapa var. Japonica)’da Verim ve Bazı Bitki Özellikleri ile C Vitamini, Protein ve Mineral Madde İçeriklerinin Belirlenmesi

Öz

Bu araştırma, 2010-2011 yılı sonbahar ve ilkbahar dönemlerinde UV katkılı PE ile örtülmüş ısıtmasız yüksek tünelde yetiştirilen mibuna (Brassica rapa var. Nipposinica) ve mizuna (Brassica rapa var. Japonica)’da; verim ve bazı bitki özellikleri ile C vitamini, protein ve mineral madde içeriklerinin belirlenmesi için yürütülmüştür. Araştırma sonucunda, mibuna ve mizuna bitkileri ekim zamanından etkilenmiştir. Buna göre mibuna için dekara verimin 1521.42 kg ve mizuna için dekara verimin ise; 1326.56 kg olarak tespit edildiği ilkbahar ekim zamanının, sonbahar ekim zamanına göre daha uygun olduğu anlaşılmıştır. Her iki bitkide de C vitamini, Kalsiyum (Ca), Magnezyum (Mg) ve Mangan (Mn) içeriklerinin ilkbahar ekim zamanında ve ham protein, Azot (N), Fosfor (P), Potasyum (K), Bakır (Cu), Demir (Fe) ve Çinko (Zn) içeriklerinin ise sonbahar ekim zamanında daha yüksek olduğu tespit edilmiştir.
