Influence of Nitrogen and Phosphorus on Flowering in African Marigold (Tagetes erecta L.) Var. Cracker Jack

An investigation was conducted during the year 2000 to study the effect of nitrogen and phosphorus on flowering in African marigold. Results revealed that among the four levels of nitrogen tested, highest level of nitrogen (N3) led to minimum number of days for the first flower-bud to become visible...

Results revealed that among the four levels of nitrogen tested, highest level of nitrogen (N3) led to minimum number of days for the first flower-bud to become visible (31.66 days), days to flower-break (38.55 days), days to full-flowering (50.66 days).
