Abstract

The effects of four doses of N (0, 20, 40 and 60 g/sq. m) and four pinching treatments, i. e. 0, 20, 30 and 40 days after transplanting on growth and flower production of Tagetes erecta cv. African Giant Double Orange were investigated, during 1980–81. The applications of 20 g N/sq. m was found to be optimum for flower production. Pinching the plants did not show significant increase in production but it delayed flower production by 10–20 days over non-inched plants. The delay could be useful for regulating the flower production and to avoid glut in the market.
