• To accomplish the study of genetic parameters of chili resistance to P. capsici, thirty cross combinations from six parents’ crosses were made by full diallel method. The resistance was assessed based on the incidence of disease, following the inoculation of 28 days-old plant of chili. Inoculation was done by dropping 5 mL of inoculum (105zoospore mL-1) at the base part of each plant. There was non-allelic interaction and overdominance effect. Chili resistance to P. capsici controlled by one positive gene. The parents contained more dominant gene, with dominance order were IPB-C4, IPB-C10, IPB-C15, IPB-C9, IPB-C8, and IPB-C2. The prediction of the possible limits of selection if homozygote genes assemble on one individual was 0.676-0.691. Broad-sense and narrow-sense heritability values for the traits were high.

• Yard long bean (Vigna unguilata L.) 777 was grown in Ultisols, which typically have low pH and high P-fixation, to determine the best correlation of soil extraction methods for soil P with yields, and to develop soil P response categories. The research was conducted at SANREM base camp in Hambaro Village, Nanggung, Bogor, Indonesia from April-August 2008. Treatments were arranged in a Split Plot Design with three replications. The main plots were treatments with soil P status of 0X, 1⁄4X, 1⁄2X, 3⁄4X and X, where is X = 1,590.5 kg SP-36 ha-1 (36% P2O5) applied once a month before planting. The subplots were P application rate of 0, 75, 150, 225 and 300 kg P2O5 ha-1. Yard long beans were planted in double rows per bed, 60 cm between rows and 25 cm within rows, 2 seeds per hole, with plot size of 1.5 m x 5 m. Coefficient correlation (r) of extraction reagents Olsen, Bray-1, HCl 25%, and Mechlich-1 were 0.772, 0.765, 0.755, and 0.732, respectively. Based on Olsen soil testing methods, soil response categories of very low, low, medium, and high were (ppm P2O5) ≤ 18.40, 18.40 < P < 117.27, 117.27 < P < 267.04, and ≥ 267.04 extracted-P, respectively. Based on Bray-1 soil testing methods, soil response categories for low, medium, and high were ≤ 87.81, 87.812O5), respectively. Fertilizer recommendation based on the Olsen soil test for low response category was 185.75 kg P2O5 ha-1, and for the medium soil category was 175.97 kg P2O5 ha-1. The Bray-1 soil test for the low response category was 184.31 kg P2O5 ha-1, and for the medium soil category was 161.39 kg P2O5 ha-1. Keywords: fertilizer recommendation, calibration, phosphorus, yard long bean
