Abstract: An experiment was formulated with four micro nutrients viz., Zinc (@ 0.25% and 0.5%), Boron (@ 0.25% and 0.5%), and their combinations were applied as foliar spray in two different intervals (One at 25 days after transplanting and other at 50 days after transplanting) to African marigold var. Pusa Basanti in the Horticulture farm of B.T. College, Madanapalle, Andhra Pradesh during 2017. Observations on plant height, number of branches days to first flowering, number of flowers, single flower weight, flower yield and xanthophyll content were recorded and statistically analyzed. From the experiment, it is concluded that foliar application of Zinc @ 0.5% + Boron @ 0.5% at two different intervals 20 and 40 days after transplanting showed better growth, flowering and xanthophyll content in African Marigold var. Pusa Basanti.
