Abstract:
An experiment was conducted at College of Horticulture, Venkataramannagudem, Dr. Y.S.R Horticultural University, Andhra Pradesh. The present study was conducted to find out the influence of coloured mulches and foliar spray of nano micronutrients and their combination on growth and yield of Strawberry cv. Winter Dawn. The experiment was laid out in a Factorial Randomized Block Design (FRBD) with twelve treatment combinations replicated thrice. The experiment was designed with two factors viz., coloured mulches mulching materials [white (A1), black (A2) and silver (A3)] and foliar spray of nano micronutrients (Nano Zinc-1000 ppm, Nano Iron-500 ppm and Nano Boron- 200 ppm) at four levels with foliar spray of nano micronutrients each at 30 DAT (B1), 30 and 45 DAT (B2), 30, 45 and 60 DAT (B3) and 30, 45, 60 and 75 DAT (B4). The foliar spray of nano micronutrients each sprayed at 30 DAT (B1), 30 and 45 DAT (B2), 30, 45 and 60 DAT (B3) and 30, 45, 60 and 75 DAT (B4). On the basis of the statistical data, it is concluded that black colour mulch and foliar spray of nano micronutrients each at 30, 45, 60 and 75 DAT showed better results in terms of number of leaves per plant, plant height (cm), plant spread (cm2), total dry matter production (g) and number of flowers per plant and yield attributes like total number of fruits per plant, fruit weight (g), fruit volume (cc), fruit diameter (cm), yield per plant (g), yield per plot (kg) and yield per hectare (t). The use of nano micronutrients and coloured mulches are highly useful for the farming community to get higher returns in strawberry cultivation.
