Effect of split application of ammoniacal and nitrate sources of nitrogen on lilium growth and yield
Article Retracted by the Authors
The aim of experiment was to evaluate the effect of split application of urea and calcium nitrate nitrogen sources on plant growth and yield in Asiatic lilies. Significant differences were observed in growth parameters and behavior of two cultivars viz., Serreda and Navona. Calcium nitrate significantly improved plant height, leaf area (LA) and LA index (LAI) recorded at 50, 75, 90, and 105 days after planting. Bulb yield parameters varied significantly between two cultivars. Calcium nitrate significantly improved bulb weight, bulb circumference, the number of bulbs plant−1 and propagation coefficient. However, the effect of three and four split nitrogen application on plant height; LA and LAI was significant at 90-105 day interval.
