The Influence of Nitrogen and Phosphorus on Watermelon Fruit Quality
Journal Title: International Journal of Plant & Soil Science - Year 2017, Vol 18, Issue 6
Abstract
This study was done to elucidate the effects of nitrogen (N) and phosphorus (P) on fruit quality of watermelon. The experimental design was a split-plot laid down in randomized complete blocks with three replications. The treatments were 0, 50, 100, 150 and 200 kg N/ha (main-plots) and 0, 25, 50 and 75 kg P/ha (sub-plots). There were no interactions between N and P treatments on all the dependent variables analyzed. Application of 50, 100, 150 and 200 kg N/ha to watermelon plants significantly (P < .0001) increased fruit quality (lycopene content, vitamin C, titratable acidity and fruit rind thickness) compared to fruit from control plants. However, P application had no significant (P = .05) effects on fruit lycopene content, vitamin C content, titratable acidity, soluble solids content and fruit rind thickness compared to fruit from control plants. In conclusion to optimize watermelon fruit quality, application of 150 kg N/ha and 50 kg P/ha to watermelon plants was recommended.
