Abstract:
An experiment entitled “effect of different levels of nitrogen and phosphorus on Calendula under sub-tropical agro-climatic conditions of Allahabad was carried out during the winter season 2007-2008 with four levels each of nitrogen viz., 0 kg, 100 kg, 150 kg and 200 kg/ha and phosphorus viz., 0 kg, 50 kg, 80 kg, and 110 kg/ha respectively. Nitrogen had a significant effect on floral parameters with nitrogen at 150 kg/ha recording significantly minimum days (64.55) to first flowering and days to 50% flowering (78.16), maximum flower weight (4.48 g/flower), number of flowers per plant (31.66), flower diameter (6.32 cm) and flower yield (136.04 q/ha. Among phosphorus applications significantly minimum numbers of days to first flowering (78.10) were recorded under phosphorus 80 kg/ha. The same treatment recorded significantly maximum flower weight (4.51 g/flower), number of flowers/plant (31.83), flower diameter (6.35 cm) and flower yield (140.8 q/ha).Interaction between nitrogen and phosphorus revealed that N2 P2 @ 150 kg N and 80 kg P/ha) gave significantly superior results in relation to the flowering parameters which included days to first flowering (62.33), number of flowers per plant (35.77) and flower yield (165.58 q/ha).
