Co-Addition of Potassium Humate and Vinasse Enhances Growth and Yield In "Wonderful" Pomegranate Under Sandy Soil
Year: 2021
Type: article
Abstract: Although "Wonderful" pomegranate has recently been cultivated in large areas of sandy soil in Egypt, it produces a low yield and quality.Soil applications of potassium humate and vinasse could effectively be used in sandy soil to enhance soil nutrient status as well as to increase crops growth and productivity."Wonderful" pomegranate trees at the Experimental Research Station of National Research Centre, El-Nubaria, Km 110 Cairo-Alex desert Road, El-Behera governorate, Egypt, were treated with soil application of potassium humate (10g, 20g, and 40 g per tree), vinasse (500 mL and 1000 mL) and their combinations to form 12 treatments including the control (water only) to study their effect on vegetative growth i.e. shoot length, leaf number, and leaf area, leaf (N, P, and K) nutrient content, perfect flower percentage, fruit set percentage, yield, fruit weight, aril/fruit percentage, T.S.S.%, and acidity%.Result shows that potassium humate & vinasse alone or together improved vegetative growth parameters i.e. shoot length, leaves number per shoot and leaf area due to their clear effect on increasing mineral leaf content that reflected also on improving yield and fruit quality compared to control.Potassium humate & vinasse alone or together have a great impact on improving not only the fruiting behavior viz perfect flower %, fruit set %, and productivity but also fruit quality for both fruit physical characteristics such as fruit weight, aril/fruit % and fruit chemical properties via TSS %.All abovementioned parameters were significantly higher in response to potassium humate and vinasse in combinations than individual application.All treatments resulted in significantly lower acidity compared to control.Among treatments, soil application of 40g potassium humate plus 1000 mL vinasse is recommended since, it has a great influence on improving growth, yield and fruit quality of "Wonderful" pomegranate under sandy soil conditions.
