Abstract:
An experiment was carried out to know the influence of liquid and carrier based biofertilizers on growth characters 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 biofertilizers (T₂) was found superior in respect of increment in tree height (0.65 m), trunk girth (3.35 cm), E-W canopy spread (0.68m), N-S canopy spread (0.63 m), canopy volume (7.05 m³), leaf area (64.81 cm²) and leaf chlorophyll content (56.66 SPAD units) during both the years of study. It was on par with trees applied with 80% RDF in combination with liquid biofertilizers (T₅) in respect of increment in N-S canopy spread (0.60 m), leaf area (63.57 cm²) and leaf chlorophyll content (54.94 SPAD units).
