Abstract: An experiment was conducted to study the effect of spacing and foliar application of micronutrients on growth, flowering and yield of china aster (Callistephus chinensis L. Nees.) cv. Metadoor. The experiment consisted of three spacing (30x25,30x30,40x25;) and with the foliar spray of different micronutrients (Fe, Zn, Mn, B) at 20, 40 and 70 DAT and laid out in factorial randomized block design with three replications. The closer spacing 30x25 cm along with the foliar application of Micronutrient (Fe) produced taller plants (53.21 cm) and flower production was also higher per unit area then other spacing and micronutrients. The interaction of spacing and micronutrients was found that closer spacing with Fe spraying gave higher yield (8.12 flowers/plant) and found economically better than the wider spacing with other micronutrients.
