Economic analysis of Carnation cv. ‘master’ cut flower production as influenced by fertilizer schedules under naturally ventilated polyhouse

摘要

The present investigation was carried out in naturally ventilated polyhouse during the year 2010 and2011 to ascertain the effect of 16 different fertilizer doses and methods of application on cut flower yield andeconomics of carnation (Dianthus caryophyllus L.) cv. Master. The results revealed that the overall cost ofcultivation as well as the economics of carnation cut flower production was significantly influenced by thefertilizer application. Carnation cv. Master plants fertigated with 250 ppm N and K through urea and MOP incombination with 250 ppm NPK foliar spray through Sujala (19 : 19 : 19 NPK) once a week producedmaximum saleable flowers (517.25 nos./m2) for three flushes over the recommended practice (437.50nos./m2). The same treatment also recorded maximum returns of 3470.33/m2 with highest B : C ratio of 2.27for three flushes.
