Response of Nitrogen and Phosphorus Levels on Calendula (Calendula officinalis L.) cv. Touch of Red Mixture

A Field experiment entitled “Response of nitrogen and phosphorus levels on Calendula (Calendula officinalis L.) cv. Touch of Red Mixture” was conducted during winter season at floriculture research field, Department of Horticulture, Sam Higginbottom Institute of Agriculture Technology Sciences, Allahabad in 2007–8008 to evaluate the growth and yield of Calendula using different levels of nitrogen and phosphorus. The Experiment was laid out in 4 x 4 factorial in randomized block design with sixteen treatments each replicated thrice. The maximum plant height (34.44 cm), number of leaf (254.22), plant spread (41.61cm), number of branches per plant (57.22), days to first flowering (62.33), flower weight (4.97 g), number of flower per plant (35.77), flower diameter (6.80 cm) flower yield per ha. (163.58 q/ha), seed yield (167.69 kg/ha) and benefit cost ratio (1: 5.02) were recorded with treatment T₁₀-N₂P₂(150 kg N/ha + 80 kg P/ha) while minimum value regarding plant growth and yield was recorded with T₀-N₀P₀ (0 kg N/ha + 0 kg P/ha).
