The Effect of Bio-Fertilizer Applications Bacillus cereus and Lysinibacillus sp On Paprika Plants (Capsicum annuum L) On Plant Nutrient Content and Cultivation Media

Abstract

This study conducted several applications of biofertilizer Bacillus cereus and Lysinibacillus sp on two doses of chemical fertilizer to find out the impact of the use of biofertilizers on paprika cultivation. The design of the research experiment used is a randomized design group of factorial patterns with two factors, the first factor is the use of biofertilizers with seven levels. The second factor is the use of chemical fertilizer doses consisting of two levels. Parameters observed in the laboratory include nutrient content N, P, K plant, and cultivation media. The results showed the nutrient content of P and K plants the highest yields were indicated by bio-fertilizer isolated 2 (P2) and biofertilizer consortium (P4) with a dose of chemical fertilizer 75% (A2). The total nutrient content of the planting media 2 best results are indicated by the treatment of biofertilizer isolated 1 (P1) and biofertilizer isolated 2 (P2) with 100% chemical fertilizer (A1). Bio-fertilizers Isolated Bacillus subtilis 1 and Bacillus subtilis 2 and Lysinibacillus sp. needs to be tested functionally as a nutrient-producing microbe as an absolute technical requirement of biofertilizer products by Ministry of Agriculture standards.
