Effect of Shade Net on Yield and Quality of Grapes cv. Thompson Seedless

The present investigation entitled -Effect of shade net on yield and quality of grape cv. Thompson Seedless- was undertaken with an objective to study the effect of shade net on yield parameters, quality parameters and maturity of Thompson Seedless grapes. The field experiment was carried out during 2013-2014 at vineyard of All India Coordinated Research Project on Fruits, Department of Horticulture, MPKV. , Rahuri. Experiment was conducted in Randomized Block Design (RBD) with nine treatments and three replications. Shade nets of four colours (Green, White, Black and Red) and two intensities (50 % and 30 % each) were used. The maximum weight of bunch (363.40g), yield per vine (10.90kg), yield per hectare (24.22t) and higher values of other yield parameters recorded in treatment T2 (green colour 30 % shade net) and was followed by T1 (green colour 50 % shade net). Maximum TSS (21.32 oBrix), total sugars (19.20 %), reducing sugars (18.06 %), non-reducing sugars (1.14 %) and TSSacidity ratio (31.82 %) were in T9 (control). The green colour shade net with 30 % and 50 % intensity were better to increase the bunch weight, average berry weight, yield per vine, yield per hectare and for retaining green colour of berries.
