Farklı Yetiştirme Ortamları ve Hümik Asit Dozlarının Turpta Bitki Gelişimi ve Kalite Üzerine Etkileri

Abstract

This research was conducted to determine the effects of different growing media and humic acid doses on plant growth parameters and quality properties in cherry-red radish. In the study, 4 different growing media [Soil, Peat:Perlite (1:1), Peat:Perlite (2:1) and Peat:Perlite (3:1)] consisting of soil and mixtures of peat and perlite at different ratios were used. In addition to, 0 (control), 500, 1000 and 2000 ppm doses of humic acid in liquid form named TKİ Hümas were investigated. Rolex F1 cherry-red radish variety (Raphanus sativus L. var. sativus) was used in the study. According to the findings obtained from the research, it was detected that Peat:Perlite (2:1) medium came to the forefront in terms of plant growth parameters and quality properties among the growing media. It was found that humic acid applications (500, 1000 and 2000 ppm) significantly increased tuber fresh weight, tuber diameter and tuber length compared to the control (0 ppm). Among the humic acid doses, the highest tuber fresh weight, tuber diameter and tuber length were obtained from 1000 ppm dose. In general, it was determined that soilless growing media and humic acid had positive effects on plant growth and quality. When the growing media and humic acid doses are evaluated among themselves, it was concluded that especially Peat:Perlite (2:1) medium and 1000 ppm dose were more effective on plant growth and quality and could be used successfully in soilless cherry-red radish cultivation in terms of agricultural sustainability and productivity.
