| Abstract | ||||
| Application of P-biofertilizer (Bacillus megaterium )and P-chemical fertilizers (rock phosphate and superphosphate) with and without organic farmyard manure was studied in a 3-factor field experiment on maize (Zea mays ). Factors being P-biofertilizer(B), P-chemical fertilizer(P) and organic manure(M). Treatments being: B0 (no-biofertilizer), and B1 (P-dissolving B.megaterium bacteria), P0 (no P), P1 (rock phosphate 70 kg Pha-1) and P2(calcium superphosphate 35 kg P ha-1), M0 (no manure), M1 (24 Mg ha-1) and M2 (48 Mg ha-1). Treatment not receiving any material gave 3.62 Mg grains ha-1 . Applying any or more of the materials increased grain yield by as low as 1% by B0P0M1 to 13% by B0P0M2 , up to 87% by B1P2M0 and as high as 129% by B1P2M2..Increase main effects were: B = 40.4% , P = 25.6% for P1 and 20.0 % for P2; although P2 surpassed P1 in presence of the biofertilizer which enhanced soluble P-fertilizer.M= 5.1% for M1 and 20.0% for M2 effictive in presence or in absence of the biofetilizer. N,P,K,Fe,Mn,Zn and Cu residual in soil after harvest increased were by up to , 38,84, 42, 112, 269, 78, and 83 % for each respectively ; and highest availble contents were 91, 9.8, 308, 4.94, 1.55,1.51 and 0.42 mgkg-1 for each respectively. | ||||
