EFFICACY OF PLANTOZYME ON PHYSIOLOGICAL PARAMETERS AND YIELD COMPONENTS IN THOMPSON SEEDLESS GRAPES UNDER PUNE CONDITION

Abstract

An investigation was carried out to study the efficacy of Plantozyme on physiological parameters, quality and yield components in Thompson Seedless grapes at NRC Grapes, Pune (latitude 18.31N, longitude 73.55E) during 2012-13, 2013-14 and 2014-15. Eleven treatments were applied in replicated RBD. Morphological, physiological and biochemical parameters were recorded at 90 days after pruning and yield parameters were recorded at harvest. The maximum shoot length and leaf area and physiological parameters like, berry diameter, berry skin thickness, and berry length were recorded with the application fertilizer dose + Planto granules @ 50 g/vine + Spraying of Planto grapes @ 2 ml/lit. Similarly, cane thickness, leaf thickness, biochemical parameters such as reducing sugar, total protein and total phenol were recorded higher in treatment of recommended fertilizer dose + Planto drip @ 2.5 ml/vine + Spraying of Planto grapes @ 2 ml/lit. The maximum yield per vine and the highest BC ratio was recorded with application of recommended fertilizer dose + Planto granules @ 50 g/vine + Planto drip @ 2.5 ml/vine + Spraying of Planto grapes @ 2 ml/lit. From the present study in general, it can be concluded that the application of Plantozyme resulted increasing berry characters, quality parameters, biochemical parameters as compared to control. In brief, the application of Plantozyme as a granule through soil @ 50g/vine, drip @ 2.5 ml/vine and foliar spray @ 2ml/l along with recommended dose of fertilizers found to be best to improve the quality and yield of Thompson Seedless grapes under Pune conditions.
