Abstract

Phosporus (P) deficiency is one of limiting factor for rice growth. In Indonesia P deficiency much occurs in acid soils. The use of P deficiency tolerant varieties is the best solution compared to the application of P fertilizer due to more efficient in cost. The purpose of this study was to evaluate the local rice germplasm collected from several regions in Indonesia to P deficiency in acid soil. The study was conducted in Jasinga West Java during wet season of 2006- 2007 with the soil condition lack of P. The experiments were conducted with the two treatments: first, without P fertilizer and second with P fertilizer equivalent of 25 kg P/ha. The total 100 accessions of rice germplasm were screened in this field based on a randomized block design with three replications. Fertilizing were given on experiments I and II with the composition: urea 300 kg/ha and 100 kg KCl. The field design was done by plotting size is 1 x 5 m2, spacing plant of 25 cm x 25 cm, and planting two seeds per...
