INFLUENCE OF MICRONUTRIENTS ON FLOWERING PARAMETERS AND FRUIT CHARACTERS OF SAPOTA cv. KALIPATTI UNDER HDP SYSTEM
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 26
Abstract
The field experiment was carried out to know the response of soil and foliar application of micronutrients (i.e., zinc, iron and boron) on flowering and fruit characters of sapota cv. Kalipatti under HDP system at Kittur Rani Chennamma College of Horticulture, Arabhavi during 2015-2016. Zinc and iron sulphates are used for soil and foliar application, boron for soil application sodium tetraborate (Jai bore) and for the foliar application solubor were used. The results indicated that the foliar application T10 -RDF + 0.5% ZnSO4 + 0.5% FeSO4 + 0.3% B per tree (i.e. in two times as foliar i.e. 1st at 50 per cent flowering and another at fruits at pea size) was shown reduced number of days (29 days) for flower initiation, flower opening fruit set (29.50 days), days taken to reach harvesting stage (195 days), maximum number of flowers ((16.95) and fruits (2.90) per shoot and the highest per cent fruit set (23.03%) and fruit retained (85.61%) at harvesting stage were noticed. Also it gave superior fruit characters like fruit weight (111.33 g), fruit length (6.06cm), fruit girth (5.78cm) and fruit volume (100.50ml) were noticed where as the lowest values was noticed in control (T1), and water spray (T2).
