Abstract/ Executive Summary:

An experiment on the performance evaluation of a grape in the hill valley was conducted at the Agricultural Research Station, Raikhali, Rangamati Hill District during 2013-14. There was only one germplasm i.e., VL Rai-001 under evaluation study. Time of harvest was June to July. The VL Rai-001 under study produced 73.85 fruits per bunch and 31 bunches per plant. Individual berry weight and berry size were 2.91 g and 1.70 cm × 1.53 cm, respectively. There were 2.20 seeds per fruit. The 10-seeds weight and seed size were 0.44 g and 6.60 × 4.10 mm, respectively. Fruit yield was 6.66 kg per vine with 80 % edible portion. TSS was 20% with very sweet organoleptic taste. Based on TSS, organoleptic taste and other parameters, the germplasm VL Rai-001 was found suitable in the hilly areas.The VL Rai-001 produced 31 bunch of fruits per vine with 73.85 fruits per bunch each fruit weighing 2.91 g containing 2.20 seeds per fruit. Edible portion and TSS were 80% and 20%, respectively. Fruit yield was 6.66 kg per vine and organoleptic taste was very sweet.

Keywords: Grape, Fuit yield, Hill valley

Location: ARS, BARI, Raikhali, Rangamati Hill District

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Variety and Species

Commodity: Grape

Objectives:

To validate the performance of a grape variety suitable for hilly areas

Methodology:

The experiment was conducted at the hill valley of Agricultural Research Station, Raikhali, Rangamati Hill District during 2013-14. The grape vine VL Rai-001 was planted during July, 2011. Each of the pits were fertilized with 5 kg decomposed cowdung, 55 g P₂O₅, 75 g K₂O, 1 kg dolomite before transplanting. Vines were fertilized with 10 t decomposed cowdung, 500 kg N, 125 kg P and 750 kg K per hectare in two equal installments, first during the last week of February and the rest during initial stage of fruit development. Irrigation, pruning, training, weeding and other protection measurse were applied as per requirement. Data were taken and statistically analyzed.
