Due to global climate change the salt-affected agricultural land has enlarged in Indonesia, especially in coastal areas. Chemical soil properties, such as pH, Na and Cl contents, as well as soil nutrients including availability of soil phosphorus, are changed by higher soil salinity. Phosphorus fertilizer management on saline soils must be done properly since improper dosage of P can worsen the severity of the effects of salinity. The study aimed to determine appropriate dose of P fertilization for salttolerant soybean genotypes in saline soil. The experiment was conducted on an agricultural field during dry season 2018 in Tuban District, East Java Province, Indonesia. The treatment consisted of two P fertilizer dosage (72 and 108 kg P2O5/ha) on two salt-tolerant of soybean genotypes (Anjasmoro variety and K-13 line). The treatment was arranged in randomized complete block design, with fourteen replicates. Soil EC at the study site during the growing season was 9-17 dS/m, while EC of irrigation water was 6-16 dS/m. Results showed that among the two tested salt-tolerant genotype, Anjasmoro variety revealed better performance than K-13 line according to growth parameters, as well as yield and yield attributes. Appropriate P fertilizer dosage for both genotypes was 108 kg P2O5/ha. [ABSTRACT FROM AUTHOR] |
