2015
Çavuşoğlu, M.N.
This study was conducted to determine the effects of various phosphorus and humic acid applications on development of gladiolus varieties in pot culture. In this study carried out in May and April (2014-2015), Rose Supreme, Red and Essential cultivars were grown in soiled pods with 0, 100, 200 mg/kg phosphorus and 0, 1000, 2000 mg/kg humic acid doses.It was determined that applications of humic acid and phosphorus had positively contribution to N, P and organic matter in soil as well as floret number of gladiolus and flower-stalk length. As a result of study, optimum doses were observed as 2000 mg/kg humic acid and 200 mg/kg of phosphorus in terms of studied characteristics.
