The research was intended to analyse the response of five papaya varieties to phosphorus fertilization in tidal swamp areas. The research was conducted at the Peatland Project (PLG) in Mentangai, Kapuas, Central Kalimantan, from August 2007 to April 2008. A split plot design was used. The main plot had the following P application: 100; 200; 300 g P/plant, and the subplot had the following varieties of papaya: Bt1; Bt2; Bt3; Bt4; Bt7. There were 3 replications and 10 plants per unit of treatment. The observed parameters were: (1) vegetative growth (plant height, stem diameter, internode number); (2) and fruit quality (fruit number, fruit weight, fruit length, fruit circumference, flesh thickness, and total soluble solid). The research result showed that four of five papaya varieties, namely Bt1, Bt2, Bt4, and Bt7 proved to have a higher growth and production response than Bt3. Therefore, the four varieties Bt1, Bt2, Bt4, and Bt7, show good prospects for development in the tidal swamp areas. P application affected significantly plant height only, but did not have an effect on other parameters of plant growth and fruiting. These findings could be used as a guide for choosing varieties suitable for cultivation in the tidal swamp areas.
