Abstract

Background: Potassium fertilizer and optimum planting density are important factors for maximizing fruit yield in field grown tomatoes. We conducted a field study to evaluate the effects of planting density and potassium fertilizers on the yield performance of CXD_222 tomatoes.
Materials and Methods: We evaluating the fruit yield of CXD_222 tomatoes in NP + 50 (nitrogen and phosphorus in a 50 x 50 cm planting pattern), NP + 40 (nitrogen and phosphorus in a 40 x 40 cm planting pattern), NPK + 50 (nitrogen, phosphorus, and potassium in a 50 x 50 cm planting pattern), and NPK + 40 (nitrogen, phosphorus, and potassium in a 40 x 40 cm planting pattern).
Findings: Wider spacing (NPK +50 and NP + 50) resulted in significantly heavier fruits per plants and produced more fruits per plants. Narrow spacing; however, produced significantly higher yield per square meter. The effect of potassium fertilizer was obvious in a sense that planting space treatments with potassium fertilizers produced significantly higher yield than the corresponding treatments without the application of potassium fertilizer. The highest yields of 5.2 and 4.75 kg m-2 were achieved in NPK + 40, NPK+50 and NP + 40, respectively whereas bigger and more fruits per plants were harvest from NPK + 50 and NP + 50, respectively.
Conclusion: This study indicates that optimizing planting space and the use of potassium fertilizers will significantly enhance fruit yield.
