The experiment of effect of source of N and dose of Pon the yield of bean (Vigna sinensis L.) of usus hijau variety was carried out since November 23, 1994 until Fe- bruary 16, 1995 at Tanggulrejo Village, Tempuran District, Magelang Regency. The experiment was carried out on Lato- sol soil with pH 5,76 and altitude 275 metres above sea level.
The purpose of this experiment is to know the effect of source of N and dose of P on the yield of bean (Vigna sinensis L.) of usus hijau variety.
The experiment was arranged with Split Plot Design, with Randomized Completely Block Design, consist of two factors of treatment and three replication. Dose of Pas Main Plot, consist of O, 75, 150, and 225 kg/ha TSP. Source of N as Subplot, consist of Calcium Nitrate manu- re, ZA, and Urea.
The result of the experiment showed that:
