Abstracts |
A field experiment was conducted during 2003/04 rainy season in Bangalore, Karnataka, India, to study the effect of phosphorus (at 0, 25, 50 and 75 kg P2O5/ha), bioinoculants, i.e. phosphorus solubilizing bacterium (PSB; Bacillus megaterium) and vesicular arbuscular mycorrhiza (VAM; Glomus mosseae), zinc (at 10 kg ZnSO4/ha) and sulfur (at 20 kg S/ha) on the nutrients uptake, quality parameters and nutrient balance in cowpea cv. TVX-944-02C. The application of 50 kg P2O5, 20 kg S, 10 kg ZnSO4/ha along with PSB and VAM resulted in a better uptake of nitrogen (155 kg/ha), phosphorus (33.6 kg/ha), potassium (57.4. kg/ha), sulfur (11.5 kg/ha), zinc (135 g/ha), iron (255 g/ha) and copper (88.6 g/ha) as compared to the other treatments. Higher nitrogen net gain of 14.5 kg/ha, protein content (20.40%) and protein yield (450 kg/ha) were noticed with 50 kg P2O5, 20 kg S, 10 kg ZnSO4 along with PSB and VAM. |
