Abstract:
The pot culture experiment was conducted during kharif season of 2019-20 in the Department of Soil Science and Agricultural Chemistry, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani to evaluate the response of ginger to graded levels of zinc and zinc solubilizing biofertilizers. Experiment consist of sixteen treatment combinations which includes four zinc solubilizing cultures (Control, Pseudomonas fluorescens, Pseudomonas striata, and Trichoderma viride) and four levels of zinc (0,20,30 and 40 kg ZnSO4 ha^-1) in factorial complete randomized design. The results emerged out indicated significant effect of zinc solubilizing cultures particularly Pseudomonas striata and zinc level upto 40 kg ZnSO4 ha^-1 on plant height, number of leaves, leaf area and rhizome yield of ginger over the other treatments. The interaction effect of zinc solubilizing cultures and graded levels of zinc i.e. Pseudomonas striata + 40 kg ZnSO4 ha^-1 noted on plant height (41.37-54.55-67.63cm for 90,150 and 210 days), number of leaves (16.29-22.32-25.93 for 90, 150 and 210 days respectively), leaf area (34.13 cm2 -35.81cm2-37.06 cm2 at 90, 150 and 210 days respectively) and rhizome yield (436.15 g pot^-1) over the other treatments.
