Effect of zn solubilizing bacteria on growth promotion and zn nutrition of rice

A comparison study between the isolated indigenous bacteria and chemical Zn fertilizer (ZnSO4.7H2O) was conducted to evaluate their potential to augment Zn nutrition of Zn responsive (NDR 359) and Zn non responsive (PD 16) varieties of rice under the green house. Three bacterial strains namely; BC,...
