Effects of Granular and Foliar Fertilizers on Fruit Quality and Yield of Tioga Strawberry Grown on Degraded Soil in Petchaboon Province

Abstract

Chemical fertilizer grades 13-13-21 and 15-15-15 were applied to the soil in combination with either foliar fertilizer grade 8-16-28 or seaweed extract sprays to increase yield improve fruit quality of Tioga strawberry. Soil application of fertilizer 13-13-21 or 15-15-15 equally at 25 gm./pt./month in combination with foliar fertilizer or seaweed extract sprays increased fruit weight over sole fertilizer 15-15-15 treatment. However 13-13-21 chemical fertilizer seemed to have better yield when compared to 15-15-15. In addition to granular fertilizers, yield per plant markedly increased by seaweed extract. Fruit sugar content was not affected by any treatments using in this experiment.
