INFLUENCE OF FYM AND VAM ON YIELD, NUTRIENT CONTENT AND ANTIOXIDANT ACTIVITY OF SPINACH (BETA VULGARIS) GROWN UNDER WATER STRESS CONDITIONSTIRUPATHI RAO H., S. SUMATHI, R. SUBHASH REDDY AND S. PADMAJA
To study the effect of FYM and VAM on yield, nutrient content and antioxidant activity of spinach under drought conditions. Recommended dose of chemical fertilizers (100% RDF, 50% RDF), farm yard manure and mycorrhizae were applied to the soil according to the treatments imposed. All green variety of spinach seeds (20) were sown in polybags and watered at every 4th day to impose drought condition. The crop was harvested around 40 days after sowing. The results revealed that significantly higher yield was found in 100% RDF+ FYM+ VAM followed by 50% RDF+FYM+VAM, VAM+100% RDF. Highest chlorophyll content was recorded in 50% RDF+FYM+VAM followed by 100% RDF+ FYM+ VAM. Highest antioxidant activity recorded in 100%RDF+FYM+VAM followed by 100% RDF and VAM. Highest vitamin C content was recorded in both 100% RDF+FYM+VAM and 50%RDF+FYM+VAM. Highest carotene content was recorded in FYM with 100% RDF followed by 100% RDF+FYM+VAM and 100% RDF. Significantly highest phenolic content found in 100% RDF+FYM+VAM followed by 50%RDF+FYM+VAM. Highest nitrogen uptake was recorded in 50% RDF+ FYM+ VAM followed by 100%RDF+FYM+VAM. Highest phosphorous uptake was recorded in 100% RDF+FYM+VAM. Lowest uptake recorded in VAM and it was on par with the treatments 100% RDF, FYM, FYM+VAM.
