Abstract

The interest in the usage of biofertilizer as alternative to mineral fertilizer increase continuously due to increasing mineral fertilizer cost and heavy metal accumulation in the soil such as cadmium. The objective of this study was to assess the effects of four biofertilizer (N-2-fixing (NF), P-solibilizing (PS), N-2 fixing-P solubilizing (NF+PS), commercial biofertilizer (CB) with and without mineral phosphorus fertilizer on seed yield forage pea (Pisum sativum spp. arvense L.) The application of biofertilizer did not affect seed yield, biological yield, crude protein content and SPAD value. The use of mineral fertilizer only increased seed crude protein content. The effects of biofertilizer on pea seed yield, biological yield and crude protein content varied significantly depending on year. These results indicated that understanding of factors such as biofertilizer, mineral fertilizer and environment will enable us to use biofertilizer as an alternative to mineral fertilizer to optimize productivity and sustainability of pea production.
