Abstract/ Executive Summary:

Five rootstocks like Rough lemon, Rangpur lime, Pummelo, Cleopetra and Calamansi were evaluated at the fruit orchard of Regional Agricultural Research Station, BARI, Cumilla during the year 2018-19. Plant height ranged from 1.55-2.58 m and plant volume ranged from 3.67-16.3m³. Rangpur lime rootstock showed better performance concerning plant volume in 2018-19.

Program Area: Variety and Species

Commodity: Sweet orange

Objectives:

To observe the performance of Rough lemon, Rangpur lime, Pummelo, Cleopetra and Calamansi as root stock on the growth and yield of sweet orange.

Methodology:

The experiment was conducted at the Regional Agricultural Research Station, BARI, Cumilla during 2018-19. The grafted saplings of BARI Malta-1 using different rootstocks like Rough lemon, Rangpur lime, Pummelo, Cleopetra and Calamansi were planted on June 2016 maintaining two spacing(2m × 2m and 3m × 3m). Variegated Malta was used as check in this experiment. Manures and fertilizers were applied @ 15 kg cowdung, 250g MoP, 230g TSP_,and 150g dolomite per tree/ pit before transplanting. Weeding, soil earthing up and insect-disease control were done as and when needed. The plants are now at vegetative growth stage.

Achievement/Findings:

The plants are in vegetative growth stage. The plant height ranged from 1.55-2.58 m and plant volume from 3.67-16.3m³. Rangpur lime rootstock showed better performance regarding vegetative parameter. This experiment is on-going and after completion of the experiment suitable rootstock for grafting of BARI Malta-1 will be selected.
