Abstract:
The present investigation entitled, Performance of Guava cultivars (Psidium guajava L.) under hill zone of Karnataka at Zonal Agricultural and horticultural Research Station Mudigere, Chikkamagaluru district an altitudes of 970.13 msl. The Sevan guava cultivar where evaluated in five years established orchard plant growth parameters, yield and quality traits viz China guava, Punjab guava, K.G guava, Barvipur guava, Laith guava and Allahabad Safeda and local cultivar check variety All cultivars are significantly showed on par except Local cultivar. Allahabad Safeda was found highest values of plant height (311.14 cm) plant girth (36.76 cm) Plant canopy E-W & N-S Direction, (252.20 & 237.29 cm) and Number of branches/plant was recorded in Allahabad Safeda (13.43 nos). Yield parameters are average fruit weight (162 g) fruit length & Diameter, (5.78/5.06 cm) fruit yield/plant, (2.14 kg) fruit yield/plot (9.19 kg) and yield/ha (2551.85 kg) and evaluate biochemical composition at post-harvest laboratory COH, Mudigere, Chikkamagaluru district of Karnataka. During the year 2020-21 mature ripe fruits of six recognise cultivars were selected for investigation the data biochemical composition revealed that TSS (11.61 Brix0) Titratable acidity (0.39%) pH, (5.01) Total sugar (7.94%) and Ascorbic acid (203 mg/100 g) quality of guava fruits were found higher in Allahabad safeda when compare to other cultivars.
