Abstract: A research was conducted in PM-AMP, Project Implementation Unit, Citrus Zone, Dailekh during the spring season 2019 to find out the effect of foliar application of micronutrient in flowering and fruit setting of mandarin (Citrus reticulata Blanco) in Dailekh, Nepal. The experiment was laid out in one factor randomized complete block design (RCBD) with five treatments and four replications. The treatments consist of foliar application of sole and combined application of Zinc and Boron namely: control (water spray), 0.15% Zn, 0.04% B, 0.1% Zn + 0.02% B and 0.05% Zn + 0.04% B. Twenty trees of same age and height were chosen from the north-facing slope. The soil of research orchard was sandy loamy. The solution for spray was made using standard procedures. Foliar application of the micronutrients was done twice, the first application was done before 45 days of the flowering and second application was done after 2 days of full bloom. The data was first entered in MS excel and R-stat was used for further analysis of the parameters. The results revealed that the different combination of micronutrient significantly influenced flowering, fruit setting percentage and the fruit drop percentage. The application of either Boron or Zinc or the combination of both were effective for enhancing flowering and fruit set as well as reducing the fruit drop in mandarin.
