Abstract

Salt affected land can be an alternative to developing soybeans in Indonesia because productive land is decreasing, while there is also an indication that there is an increase in salinity in productive land. Planting tolerant variety combined with P fertilizer is an effective management to increase soybean productivity of salt affected land. The objective of this study was to identify dosage of P fertilizer and salt tolerant genotypes for improving growth and yield of soybean on saline soil. The trial was conducted on saline soil in Tuban district, East Java at dry season 2018. The trial consisted of two factors that were arranged in a completely randomized block design, six replications. The first factor was two doses of P ferilizer 72 P2O5 kg/ha and 108 P2O5 kg / ha. The second factor was two soybean genotypes: Anjasmoro variety and K-13 line. Soil salinity levels during the soybean planting period are classified as high from 10-18 dS /m, and irrigation water salinity reaches 6-16 dS / m. The results showed Anjasmoro variety and P fertilizer of 108 kg / ha P2O5 was more prospective to be developed in soybean cultivation in saline condition
