Advancing maturity and improving quality of kokum (Garcinia indica Choisy) fruits by post flowering foliar sprays.

摘要

A study was conducted during 2006-07 in Dapoli, Ratnagiri, Maharashtra, India to advance the mature and improve the quality of kokum fruits through post-flowering spraying of chemicals. The treatments were: (T1) urea at 0.5%; (T2) urea at 0.5% applied twice; (T3) KNO₃ at 0.5%; (T4) KNO₃ at 0.5% applied twice; (T5) monopotassium phosphate at 0.5%; (T6) monopotassium phosphate at 0.5% applied twice; and (T7) untreated control. Observations were recorded on fruit retention (%), advancement in maturity (days), fruit length, breadth and circumference (cm), fruit weight (g), total soluble solids ( degrees Brix), acidity (%) and sugar (%). Results showed that KNO₃ and monopotassium phosphate advanced the ripening of kokum fruits over the control. Fruits in T6 ripened 34 days earlier than the control. T2 and T3 recorded the highest values for all fruit physical and chemical properties studied.
