Description :
Nanotechnology has the potential to refashion agriculture and food industry due to development of new tools for the treatment of diseases and rapid disease detection as well as mechanism to absorb nutrients by plants hence the present study was planned to study the effect of ZnO Np on onion growth and productivity. Sowing was done in second week of June. Thirty days old onion seedlings were transplanted in pots. In each pot, 4 same size seedlings were planted at equal distance and depth. Plants were sprayed with graded concentrations (00, 10, 20, 30, and 40 g ml-1) of ZnO NPs along with sticker. Plants were treated after every 20 days. Growth parameters like plant height, No. of leaves, Leaf area, etc., were determined after 3 month. Yield parameters like Fresh weight of bulbs and bulb diameter were determined at the time of harvest. The results of present investigation clearly indicate that ZnO NPs applied at 10-20 μg ml-1 doses significantly increased plant height, number of leaves per plants and bulb weight.
