PENGARUH KONSENTRASI DAN FREKUENSI PEMBERIAN PUPUK SUPRA TERHADAP HASIL TANAMAN BUNCIS PUTIH (Phaseolus vulgaris, L.)
ABSTRACT
The research about the effect of concentration and frequency of application of Supra fertilizer on yield of white beans (Phaseolus vulgaris, L.) had been carried out since 31th May until 8th August 2001 at Surojoyo Village, Candi Mulyo District, Magelang Regency. The soil type is latosol with pH 6,5 and altitude is 430 meters.
