Effect of micro-nutrients (B, Zn and Cu) on plant growth of gerbera (Gerbera jamesonii L.) under polyhouse condition

Abstract

Gerbera is one of the most important cut-flowers, successfully grown under different conditions in several areas of the world and meeting the requirements of various markets. This success is primarily due to the wide range in colour and shape of the flower. The present investigation was undertaken at Department of Horticulture, SHIATS, Allahabad, during the year 2015-2016. The experiment was laid out in simple R.B.D. with three replications and thirteen treatments separately. Studies showed that, significant effect on the number of leaves (15.60), spread of plant (53.07cm), minimum days of first flower bud emergence (77.37), minimum days of first flower harvest (87.43), flower diameter (10.83 cm), stalk length (57.67 cm), stalk diameter (8.32 mm), petal length (5.39 cm) gross return (121771.00), net return (65782.50) and Cost : Benefit ratio is (1:2.17) was observed maximum in treatment (T10) with 0.5% B +0.5% Zn +0.25% Cu whereas height of plant (33.23 cm) was noted highest in (T11) with 0.5% B +0.25% Zn +0.5% Cu.
