Abstract/ Executive Summary:

The study was conducted at the Horticulture farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from December 2011 to May 2012. Three Japanese bunching onion lines viz. L₁: White star, L₂: Moto kura and L₃: Akahige or Red hero were tested in this study. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Statistically significant variation was recorded for most of the characters of Japanese bunching onion lines. Tallest plant (60.7 cm), maximum number of leaves (8.3), maximum leaf area (333.0 cm), fresh weight of leaves plant^-1 (81.7 g), pseudo stem length (13.2 cm), pseudo stem diameter (20.8 mm), fresh weight of pseudo stem plant^-1 (28.5 g), yield plot^-1 (2.9 kg) of pseudostem and highest yield of pseudo stem (14.3 tha^-1) were found in L₂, whereas the lowest was recorded from L₃. Moto kura was found suitable for cultivation in Bangladesh.

Start Date: 01-12-2011

End Date: 31-05-2012

Program Area: Variety and Species

Commodity: Onion

Objectives:

To evaluate the performance of Japanese bunching onion (Allium fistulosum L.) lines in Bangladesh condition.

Methodology:

The study was conducted at the Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to observe the growth and yield of different Japanese bunching onion lines during the period from December 2011 to May 2012. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The total area was divided into three equal blocks. Each block was divided into 3 plots where 3 Japanese bunching onion lines viz. L₁: White star; L₂: Moto kura and L₃: Akahige or Red hero (Plate 1) were allotted at random. There were 9 unit plots altogether in the experiment. The size of the each plot was 2.0 m × 1.0 m. The distance maintained between two blocks and two plots were 1.0 m and 0.5 m, respectively. Seeds were sown in field on 15 December 2011 in line with maintaining the distance between line to line 20 cm and plant to plant 10 cm spacing that maintained through thinning up. Cowdung (10 ton ha^-1), urea (240 kg ha^-1), TSP (220 kg ha^-1), MOP (150 kg ha^-1) and gypsum (110 kg ha^-1) were used as recommended by BARI for onion. Entire cowdung, TSP, gypsum, ½ urea and ½ MOP were applied during final land preparation. Rest ½ urea and MP were applied at two installments, 25 and 50 days after sowing. Irrigation, weeding and fungicides & insecticides spraying were done as necessary to crop. Data were collected on plant height, leaf number, leaf area, pseudo stem length, pseudo stem diameter, weight of leaves plant^-1, weight of pseudo stem plant^-1 and yield plot^-1 also calculated the yield ha^-1. Leaf area (single plant) was measured by using CL 202 leaf area meter and diameter of pseudostem was measured with a Digital Caliper-515 (DC-515). Crop was harvested at 180 days after sowing for measuring the yield. Yield ha^-1of pseudo stem of was calculated by calculating the weight of yield plot^-1 into hectare and was expressed in ton. All parameters were statistically analyzed by using MSTAT-C program. Mean for all the treatments was calculated, analysis of variance for each of the characters was performed by F-test and difference between treatments was evaluated by Least Significant Difference (LSD) at 5% level of significance.

Achievement/Findings:

Considering the findings of the present experiment, it may be concluded that Moto kura Japanese bunching onion lines showed significantly better performance compare to the other lines used in this experiment. So, Japanese bunching onion could be successfully grown in Bangladesh environment which would partially supplement the onion requirement of the country. However, for confirmation of the present findings, multi-location field trials are needed.
