Yield and quality components on two tomato varieties as influenced by phosphorus fertilizer application

Increasing the quality of tomatoes such as lycopene and beta carotene can also increase the value of the product so as to help farmers and the tomato processing industry. One effort to increase the content of lycopene and [3-carotene is by fertilizing phosphorus. The objective of this research was to determine the impact of phosphorus fertilizer and variety of local tomato on lycopene and [3-carotene content. Two local varieties of tomato (Karina and Mawar) were planted in polybags using different level of phosphorus fertilizer (75,100,125,175 kg.ha(-1) P2O5). The results showed that the application of phosphorus fertilizer influenced the quality of tomato. Phosphorous fertilizer fertilization of 175 kg.ha(-1) gave optimum results on and yield of tomato plants. The tomato fruit of Mawar variety had the higher amounts of lycopene and beta carotene.
