Effect of spraying with nano zinc and coconut milk on the growth and flowering of the petunia plant

Year: 2025
Type: article
Abstract: This study examined the influences of spraying nano zinc and coconut milk and their interplay on growth, flowering and chemical indicators on Petunia grown in a lath house over the 2022 growing season. During the experiment, two factors were studied: spraying nano zinc (Z) at 10 and 20 mg L-1 concentrations and spraying coconut milk (C) at concentrations of 10, 20 and 30 %. Additionally, distilled water was sprayed as the control treatment for both factors. All of the traits examined were significantly impacted by nano zinc spraying, the greatest results for the attributes were obtained at a concentration of 20 mg L-1 (Z2), including (plant height, number of branches, leaf area, flowers number, flower diameter, flower weight, total chlorophyll, total carbohydrates, nitrogen, Phosphorus and potassium). Conversely, the coconut milk spraying treatments significantly impacted all the attributes examined except flower weight. The highest values for the traits were obtained with the 20 % (C2) treatment, including (plant height, number, leaf area, flowers number, flower diameter, total chlorophyll and total carbohydrates). In contrast, the concentration of 30 % (C3) achieved the best results for the traits (nitrogen, phosphorus and potassium). These results demonstrate the potential of combining nano zinc and coconut milk as an eco-friendly biostimulant strategy for ornamental crops.
