Effect of drip irrigation and fertigation levels on growth and yield of Gerbera under greenhouse conditions

摘要

The experiment was conducted in fan pad greenhouse with three irrigation levels viz, 0.80,0.60 and 0.40 PE (pan evaporation) and three fertigation levels viz, 120,100 and 80% RD (recommended dose) to determine suitable irrigation level and fertilizerdose for gerbera under protected cultivation. It was observed that the stock thickness, stock length and number of flowers/ plant/ year were the maximum due to 0.40 PE level of irrigation and 80% RD of fertigation. The economic analysis of gerbera production revealed that the treatment combination of 0.60PE x 80% RD has resulted into the maximum B.C. ratio of 1.59 followed by B.C. ratio of 1.57 in 0.40 PE x 80% RD and 0.60 PE x 100% RD.
