Abstract

The effect of P fertilizer rates on growth and production parameters of waterleaf [Talinum triangulare (Jacq.) Willd] were studied over two months (February-April 2010) in Bogor. Treatments of five P-rates (0, 200, 400, 600, and 800 kg SP-18 ha-1) were laid out in a randomized complete block design with three replications. Generally, the effect of P fertilization in waterleaf was mostly prominent at 8th week after planting (WAP). The increase of  P rates increased leaf area, leaf fresh weight, edible part (shoot weight), and protein production; but decreased anthocyanin production. These results suggested that to produce high protein and anthocyanin, waterleaf must be fertilized with 400 kg SP-18 ha-1; and P fertilizer must be applied at least two weeks before planting.   Keywords: inorganic fertilizer, phosphorus, portulacaceae, secondary metabolite
