Abstract
An investigation entitled “ Effect of foliar spray of nano zinc and boron on yield and quality of anthurium grown in coco peat medium”. was carried out under protected conditions at the polyhouse complex, Department of Horticulture (Floriculture) COA,
GKVK, UAS, Bangalore during the year 2022. The experiment was laid out in a CRD with a factorial concept comprising of 14 treatment combinations (T1(RDF), T2(RDF +Ca + Mg+microbial consortium), T3 (T2 + nano Zinc @ 0.1 ppm) ,T4 (T2+ nano Zinc @0.2 ppm), T5 (T2+ nano Boron @0.1 ppm), T6 (T2+ nano Boron @0.2 ppm), T7 (T2+Conventional zinc @0.1 ppm), 8(T2+Conventional zinc @0.2 ppm), T9 (T2+Conventional boron@ 0.1 ppm), T10(T2+ Conventional boron@0.2 ppm),T11 (T2+nano Zinc+nano Boron @ 0.1+0.1 ppm), T12 (T2+nano Zinc +nano Boron@0.2+0.2 ppm), T13 (T2+Conventional Zinc
+Conventional Boron @ 0.1+0.1 ppm), T14(T2+Conventional Zinc + Conventional Boron @0.2+0.2 ppm)) replicated thrice. The frequency of foliar spray of the nutrients was done twice in a month. Significantly higher vegetative growth parameters like plant height (63.5 cm), leaf area (584.5 cm2) and yield parameters like Number of flowers per m2 (70.9), stalk length (58.5cm), spadix length (8.21cm), spathe width (8.21cm) was recorded at 30, 60days and at harvest in T12 (T2+nano Zinc +nano Boron@0.2+0.2 ppm)compared to all other treatments. Shelf life (vase life) was 33.06 days with a maximum sucrose solution uptake
(20.12 ml). It was concluded that Nano Zinc and Nano Boron application in T12 was found to be the best treatment in enhancing the anthurium flower yield and also the vase life.
