An investigation was carried out to study the effect of different levels of single super phosphate on growth and yield of rose grown in soil media under polyhouse conditions. The treatments comprised of application of two levels and two methods of single super phosphate with application of monocalcium phosphate as a control treatment. The application of 18 g single super phosphate in two equal splits (basal and 50 days after planting) significantly increased growth with respect to number of leaves (32.5 per plant), number of branches (3.75 per plant), plant height (49.7 cm), number of flowers (3.75 per plant) and least number of days required for flowering (8.56) from bud initiation. Significantly higher yield of rose and nutrient uptake was observed in the same treatment. The significant increase in fresh and dry weight of flower (24.98, 5.5. g, respectively) were reported in same treatment. The treatment of 18 g single super phosphate in two equal splits also recorded significantly higher total uptake of macro and micronutrients by rose over other treatments of single super phosphate and monoammonium phosphate (Control).Keywords

The results of the experiment revealed that K and Zn deficient treatments showed significantly inferior results in respect to growth parameters viz., number of suckers per plant, number of leaves per plant, plant height and plant spread. The K and Zn deficient treatments showed significantly inferior results in respect to quality parameters viz., height of flower stalk, flower diameter, green and dry weight of individual flower, vase life of flower, number of flower per plant and more number of days required for flower maturity over all nutrients application treatments. The significant reduction in yield of gerbera, green and dry matter production per plant, nutrient content and nutrient uptake observed due to the K and Zn deficient treatment. The K deficient treatments showed marginal necrosis of leaves and flowers became pale, which are the typical symptoms. The Zn deficient treatments showed formation of smaller sized thicker leaves which caused rosette formation and interveinal chlorosis of leaves with green spots at somewhere which are typical symptoms.
