Abstract:
An experiment was carried out to know the influence of liquid and carrier based bio-fertilizers on fruit quality parameters of guava cv. Taiwan White at College of Horticulture, Dr. YSRHU, V.R. Gudem, Andhra Pradesh during 2019-20 and 2020-21 on four year old guava trees planted at 2.8 x 2.8 spacing. The experiment was carried out in a factorial RBD with three replications. Among the treatments, all the inorganic and biofertilizer combinations exhibited profound effect on growth parameters than inorganic fertilizer alone. Guava trees applied with 100% RDF along with liquid bio-fertilizers (T₂) was found superior in respect of TSS (9.47 ⁰Brix), total sugars (8.19%), reducing sugars (4.76%), ascorbic acid content (233.52 mg/100 g pulp), pectin content (1.16%), calcium content (23.67 mg/100 g pulp) and phosphorous content (36.33 mg/100 g pulp) in fruits during both the years of study. It was on par with 80% RDF + liquid biofertilizers (T₅) for TSS (9.38 ⁰Brix) and total sugars (8.19%).
