Abstracts |
A field experiment was conducted during the rainy season of 2003-04 in Bangalore, Karnataka, India, to study the effect of phosphorus, bioinoculants, zinc and sulfur on the nodulation and dry matter accumulation in cowpea cv. TVX-944-02C. Application of 50 kg P2O5, 20 kg S, 10 kg ZnSO4/ha along with a phosphorus-solubilizing bacterium (PSB; Bacillus megaterium var. phosphaticum) and vesicular arbuscular mycorrhiza (VAM; Glomus mosseae) resulted in higher dry matter accumulation in leaves (8.92 g/plant), stem (11.8 g/plant) and total dry matter accumulation (20.72 g/plant). Higher number of nodules (13.5, 14.0 and 7.5/plant), dry matter of nodules (0.42, 0.52 and 0.30 g/plant) and effectivity of nodules (8.5, 9.5 and 2.6/plant) at 45, 60 and 75 days of sowing, respectively, were also noticed with 50 kg P2O5, 20 kg S, 10 kg ZnSO4/ha along with PSB and VAM. |
