Abstract/ Executive Summary:

Performance of BARI Malta-1 was studied using different rootstocks at the Regional Agricultural Research Station, RARS, Jamalpur during the year 2018-19. The rootstocks used in the experiment were Rangpur lime, Rough lemon, kalamanchi, and Pummelo. The highest plant height (2.62 m) was found in Rangpur lime and the lowest in Rough lemon. Number of branches ranged from 2.2-3.6. Rangpur lime rootstock show better performance in all vegetative parameter.

Location: HRC, RARS,Jamalpur, Bangladesh

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Sweet orange

Objectives:

To identify the rootstocks on leaf nutrients, tree growth, fruit quality and yield of Sweet Orange.

Methodology:

The study was conducted at HRC, RARS,Jamalpur during the year 2018-19. BARI Malta-1 were used as scion and four rootstocks i.e Rangpur lime, Rough lemon, kalamanchi, and Pummelo were used to find out the best one. The plants were planted on 2 March 2016 in row system giving a spacing of 3m×3m. All plants are 1.5 year old. The plants were fertilized with cow dung (20 kg), urea (100g), TSP (200 g), MP (100 g), gypsum (100g) , Zinc (4 g) & boron (4 g) in two equal installments one at the onset of rains and another at the end of rainy season. Weeding, irrigation and other management practices were done as and when necessary.
