Effect of Micro Nutrients Spray on Growth, Yield and Flower Quality of Gladiolus cv. White Prosperity

The present investigation on effect of micro nutrients spray on plant growth, spike yield and flower quality of gladiolus (Gladiolus grandiflorus L.) cv. White Prosperity was under taken in the Department of Horticulture, SHIATS, Allahabad. The experiment was laid out in RBD (5 x 5 Factorial), having five levels each of zinc (0.0%, 0.2%, 0.3%, 0.4% and 0.5%) and boron (0.0%, 0.2%, 0.3%, 0.4% and 0.5%), consisting a total of 25 treatment combinations. Results showed that the foliar application of boron and zinc alone at all rates and as combination significantly influenced plant growth, spike yield and flower quality with maximum value at 0.4% boron and 0.4% zinc levels. As a result of interaction between boron and zinc, the best results regarding plant growth, spike yield and flower quality were obtained with treatment combination B3 Z3 (B 0.4% + Zn 0.4%).
