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.

Keywords: Kalamanchi, Pummelo. Rootstock, Orange

Program Area: Variety and Species

Commodity: Orange

Objectives:

In Jamalpur region, pummelo root stocks are used for citrus grafting. But the common problem is that it can’t tolerate water logging. So it is utmost to select a root stock which can avail adverse situation. For this reason this experiment conducted to select a better root stock.

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.

Achievement/Findings:

The growths of plant were satisfactory. Plant characters BARI Malta-1 on different root stocks have been recorded.The plant height range from 1.92-2.62 m. The highest plant height (2.62 m) was found in Rangpur lime and the lowest in Rough lemon. Base girth ranged from 10.5-19.5 cm. The highest base girth (19.5 cm) was observed in Rangpur lime and the lowest in Rough lemon. Number of branches ranged from 3.2-3.8. Rangpur lime rootstock show better performance in all parameter.
