Assessment of rejuvenated mango cultivars for yield and quality under south Gujrat condition

Abstract

The study was conducted to investigate the assessment of rejuvenated cultivars of mango involving ten different rejuvenated mango cultivars namely Kesar, Rajapuri, Alphonso, Totapuri, neelum, Langra, Sardar, Jamadar, Dadamio and Vanraj was conducted in Randomized Block Design (RBD) with five replications at Instructional Farm, ASPEE College of Horticulture and Forestry, navsari Agricultural university, navsari, Gujarat, India. The vegetative characters viz., tree height (m), trunk girth (m), canopy spread (m) and canopy volume (m3) were observed to revealed profound effect due to rejuvenated mango cultivars. Among different rejuvenated mango cul-tivars, Rajapuri exhibited maximum tree height (6.09 m), trunk girth (1.47 m), canopy spread (4.99 m) and canopy volume (8.92 m3).With respect to flowering characters, early flower bud initiation (December 13, 2018), early flowering (December 21, 2018), early full bloom (January 28, 2019) and early fruit set (February 05, 2019) were observed in cv. Vanraj. higher number of fruits/tree (274.20) and yield (110.46 kg/tree) were obtained in cv. neelum and Totapuri, respectively. Significantly maximum weight of fruit (617.39 g), width of fruit (10.94 cm), pulp weight (518.17 g) and pulp:peel ratio (7.96) were observed in cv. Vanraj, while maximum fruit length (16.59 cm) and peel weight (68.43 g) were recorded in cv. Totapuri and Rajapuri, respectively. The higher total soluble solids (22°Brix), total sugars (15.40%), reducing sugar (5.35%) and minimum titratable acidity (0.15%) were observed in cv. Langra and maximum ascorbic acid was recorded in cv. Totapuri (30.27 mg/100 g).
