Synergistic Effect of Organic and Biofertilizers on Strawberry Cultivation

In the contemporary era, the excessive use of chemical fertilizers in areas where strawberries are intensively cultivated disrupts the balance of nature and reduces economic efficiency. Therefore, using organic and biofertilizers in sustainable agriculture can solve these problems. The effect of organic fertilizer and other treatments on the yield, quality, and plant growth of the Monterey strawberry variety was investigated. Solid farm manure and a liquid organic fertilizer of vegetable origin were used as basic fertilizers, while five different commercial fertilizers containing bacteria and mycorrhiza were used as complementary fertilizers. In addition, this study examined plant growth parameters, including root length, stem diameter, leaf area, yield per plant, fruit weight, pH in the fruit, SSC, acid, SSC-to-acid ratio, and plant nutrient content. The Biofarm+Botanica+Fontera microzone bacterial fertilizer ( Azosprillium brasilense , Azotobacter vinelandii , Rhizobium trifollii , Pseudomonas fluorescens , Bacillus subtilis , Bacillus licheniformis , Azotobacter chroococcum , Bacillus amyloliquefaciens , and Bacillus mucilaginosus ) treatment provided the best results; namely, it produced the highest total yield (250.17 g plant −1 ), largest fruits (18.13 g), highest SSC-to-acid ratio (18.05), and best nitrogen, phosphorus, potassium, calcium, and magnesium contents in the leaves. Similarly, the same treatment produced the longest root, thickest stem, and maximum leaf area. As a result of this study, it is recommended to use biofertilizers together with organic fertilizers to ensure high-quality fruit production.
