PHYSIOLOGICAL INVESTIGATION ON GROWTH AND YIELD OF SAPOTA [MANILKARA ACHRAS (MILL.) FOSBERG].

A study on physiological investigation on growth and yield of sapota [Manilkara achras (Mill.) Fosberg] was carried out in the "All India Co-ordinated research project on Fruits", Kittur Rani Channamma College of Horticulture, Arabhavi, Karnataka during 2012-2013. Among all the cultivars studied Cv. DHS-1, DHS-2, CO-1 showed maximum vegetative growth, cv. Cricket Ball, PKM-1, PKM-2 and DHS-2 showed best results with respect to physiological characters. Cv. Kirthabharthi, Cricket Ball and DHS-2 were found to be good with respect to bio-chemical characters. Cv. DHS-1, Kalipatti, Tagapampudi, Long Oval, Kirthabharthi, Cricket Ball, PKM-1, Oval and Gavarayya were found to be best with respect to yield and quality parameters. Correlation coefficient studies showed that, positive correlation for relative water content with fruit volume and fruit breadth, light transmission rate with individual fruit weight, fruit breadth and fruit volume. Number of fruits per plant with yield (kg/plant). Individual fruit weight with fruit breadth and fruit volume. Fruit breadth was positively correlated with fruit volume.
