EFFECT OF BIO-FERTILIZER AND ORGANIC MANURES ON YIELD AND QUALITY OF 'RED FLESHED' GUAVA
An experiment was conducted on 4-year-old guava trees during 2007-2008 to study the effect of bio-fertilizer and of organic manures (FYM) on yield and quality of Red Fleshed guava. Average maximum fruit yield for the rainy and winter season crop was 38.2 and 19.0 kg/tree respectively, with 250 g Azotobactor + 20 kg FYM. Vermicompost (20 kg/tree) had significantly higher yield over control and was recommended as the third best treatment among all regarding the yield. Highest fruit weight 198.2 and 299.2 g, fruit length 5.9 and 7.2 cm and fruit breadth 7.0 and 7.4 cm for rainy and winter season crop, respectively, were obtained with the application of Phosphobacterin (50 ml/tree), which was, however, at par with that obtained with Vesicular Arbuscular Mycorrhiza (VAM, 10 kg/tree). Highest total soluble solids (16.1 and 17.9°Brix) for rainy and winter season crop, respectively, as well as vitamin C (189.6 mg/100 g) was obtained with the application of VAM. Acidity was not influenced by the application of bio-fertilizer. However, acidity was highest (0.54%) under FYM treatment. From the present study, it can be concluded that the application of bio-fertilizer was more effective than organic manures in enhancing fruit growth parameters in guava in both seasons. When bio-fertilizers were grouped together, P-solubilizers were found to have more beneficial influence on fruit physico-chemical characteristics of Red Fleshed guava as compared to N-fixers.
