Description A field experiment entitled ?Effect of fertigation with water soluble macro nutrients and spraying of chelated micro nutrients on growth, yield and vase life of gerbera (Gerbera jamesonii bolus ex. hook.) under saline water conditions of polyhouse? was conducted at Floricultural Research Station, Rajendranagar, Hyderabad during Rabi 2013-2014.
The experiment was conducted with different macro ( water soluble NPK 100% RDF, water soluble NPK 80% RDF and water soluble NPK 60% RDF) and micro nutrients (rexolin @ 0.5 g per litre, rexolin @ 1 g per litre, rexolin @ 1.5 g per litre and rexolin @ 2 g per litre) levels. The data were recorded on plant height, number of leaves per plant, leaf area, days from flower bud to full flower opening, length of flower stalk, diameter of flower stalk, flower diameter, diameter of disc, diameter of flower neck, number of flowers per plant, number of flowers per square meter and vase life of gerbera with 12 treatments replicated thrice in Split Plot Design.
Among the different levels of macro nutrients, water soluble NPK 100% RDF (F1) recorded maximum plant height (38.32 cm), number of leaves per plant (22.37), leaf area (150.95 cm2), minimum days from flower bud to full flower opening (10.27 days), length of flower stalk (64.23 cm), diameter of flower stalk (0.745 cm), flower diameter (10.25 cm), diameter of disc (3.46 cm), number of flowers per plant (4.87), number of flowers per square meter (53.62) and vase life (8.27 days).
Among the different levels of micro nutrients, rexolin @ 1 g per litre (M2) recorded maximum plant height (38.75 cm), number of leaves per plant (22.31), leaf area (149.83 cm2), the minimum days from flower bud to full flower opening (10.13 days), length of flower stalk (65.05 cm), diameter of flower stalk (0.723 cm), flower diameter (10.28 cm), diameter of disc (3.29 cm), number of flowers per plant (5.08), number of flowers per meter square (55.91) and vase life (8.11 days).
Among the interactions, water soluble NPK 100% RDF with rexolin @ 1 g per litre (F1M2) recorded maximum plant height (41.41 cm), number of leaves per plant (24.73), leaf area (156.73 cm2), minimum days from flower bud to full flower opening (9.50 days), length of flower stalk (68.50 cm), diameter of flower stalk (0.780 cm), flower diameter (10.61 cm), diameter of disc (3.82 cm), number of flowers per plant (5.50), number of flowers per square meter (60.50) and vase life (8.75 days).
Our findings concluded that NPK 100% RDF and rexolin @ 1 g per litre were found effective in promoting growth, yield and vase life of gerbera.
