Abstract:
A field experiment was carried out to study the effect of N, P2O5 and K2O on vegetative, floral and seed production characters of Zinnia elegans cv. Gaint Flowered Mixed at Horticultural Research Station, Mondouri, B.C.K.V., West Bengal in two consecutive seasons (i.e. rainy and winter season). N, P2O5 and K2O each at 100 and 200 kg ha-1 were tested in all possible combinations in Randomised Block Design. Although plant height, number of leaves plant-1 and leaf area plant-1 recorded highest by application of N, P2O5 and K2O each at 200 kg ha-1, however, these remained statistically at par under application of 200 kg N ha-1 + 100 kg P2O5 ha-1 + 200 kg K2O ha-1. Highest number of primary and secondary branches was recorded under a treatment combination of 200 kg N ha-1 + 100 kg P2O5 ha-1 + 200 kg K2O ha-1. Application of 200 kg N ha-1 + 100 kg P2O5 ha-1 + 200 kg ha-1 also resulted in significantly higher number of flowers plant-1, number of seeds flower-1 and seed yield plant-1. Significant decrease in all the characters was observed under control.
