Preliminary research on biofertilizer (Alginure) Application in Paddy Field

Abstract

The effects of biofertilizer (Alginure) on yield and other components of rice were invesigated at Suphan Buri Rice Experiment Station during 1990-1992. Alginure, the trade name of a mixture of blue green algae, was applied solely (62.5 kg/ha) or in combination with chemical fertilizer (37.5-37.5-0 or 75-37.5-0 kg N-P2O5-K2O/ha) for SPR90 rice variety grown on Saraburi soil series (fine clayey, mixed, nonacid, isohyperthermic, Aeric Tropaquepts). the results showed that Alginure had no effect in increasing rice yield. Rice yield obtained from chemical fertilizer or from a combination of chemical fertilizer and Alginure were more than from Alginure or control.
