Abstract/ Executive Summary:

The field experiment was conducted at the Regional Agricultural Research Station, Rahmatpur, Barisal in rabi season of two consecutive years of 2001-2002 and 2002-2003 with a view to determine the effects of different combinations of zinc (Zn), boron (B) and copper (Cu) nutrients on bulb yield, storability and economic return of onion in the study area. The soil of the experimental area belongs to the Ganges Tidal Floodplain Alluvium Tract under AEZ-13. The Zn, Band Cu nutrients consisted of eleven treatment combinations namely Zn0B₁Cu₁, Zn₂_.5 B₁Cu₁, Zn₅B₁Cu₁ Zn₇_.5 B₁Cu₁, Zn₅ B₂Cu₁ Zn₅B₃Cu₁, Zn₅ B₁Cu₀_, Zn₅B₁Cu_2, kg/ha. Different plant characters like plant height, leaf length, pseudostem length, horizontal and vertical diameters, single bulb weight and bulb yield of onion were differed significantly due to application of different treatment combinations. Of the treatment combinations, the maximum bulb yield ( 16.68 tlha) was obtained with the treatment Zn₅B₂ Cu₁ kg/ha due to production of largest horizontal and vertical diameters (4.74 and 4.35 cm, respectively) and heaviest single bulb ( 36.42 cm) of onion by the treatment.

End Date: 00-00-2003

Program Area: Crop-Soil-Water Management

Commodity: Onion

Objectives:

To determine the effects of Zn, B and Cu on onion yield , storability and economic return in the southern region of Bangladesh

Methodology:

The field experiment was carried out at the Regional Agricultural Research Station, Rahmatpur, Barisal during the rabi seasons of 2001-2002 to 2002-2003. The soil of the experimental area belongs to the Ganges Tidal Floodplain Alluvium Tract under AEZ-13. Before planting of onion the composite soil samples (0-15 cm depth) were collected from the experimental field for determining the initial nutrient status of the soils. Initially all the experimental plots were applied of N 100 P80 K 100 S20 kg/ha as a blanket dose in the form of urea, triple super phosphate, muriate of potash and gypsum, respectively. Then different l eve ls of micronutrients (Zn, B and Cu) were applied according the treatment specifications w hi c h consisted of four levels of Zn (0, 2.5, 5.0 and 7.5 kg/ha), four levels of B (0, l, 2 and 3 kg/ha) and four levels of Cu (0, I, 2 and 3 kg/ha). The whole amounts of P, K, S, Zn, B and Cu and I /3'd urea were applied at the time of final land preparation. The remaining 2/3'd urea were applied in two equal installments at 3rd and 5tth week after transplanting as top dressing. Onion seedlings of 45 days old of BARI Peaj-1 variety were transplanted in consecutive two years on 4 November, 200I and 5 November 2002, respectively. The plant spacing was row-to-row 20 cm and plant-to-plant distance was I 0 cm. After transplanting, all the intercultural operations were done for proper growth and development of onion plants. Bolting was discouraged by nipping off the flower stalks. Plant sampling was done at different intervals (50, 65 and 80 OAT) to take growth related parameters. The onion bulb was harvested on 4 April 2002 and 6 April 2003 in two consecutive years, respectively. Before harvesting, ten plants were randomly selected from each plot for recording different plant characters like plant height, number of leaves/plant, leaf length, horizontal and vertical diameter of bulb, pseudo stem length and diameter, weight of single bulb etc. The bulb yield was taken plotwise and then converted into ton per hectare: Then the onion bulbs were stored on bamboo racks into a room to study the impacts of micronutrients on storability. During the storing g period cumulative weight and rotten loss of bulbs/plot were recorded and converted into percentage. The data were analyzed statistically and the means were separated by Duncan's Multiple Range Test.

Achievement/Findings:

During the storage of onion bulb, the lowest cumulative weight loss (25.66 o/o) was observed in Zn 7.5B 1Cu1 kglha and the highest (45.76 o/o) was found in Zn₀B₁Cu₁ kg/ha at 180 days after storage. The maximum gross return (Tk 66750.00/ha), gross margin (Tk 154070.18/ha) and benefit cost ratio ( 12.15) were provided by Zn₅ B₂ Cu₁ kg/ha followed by Zn₅B₃ Cu₁ k/lha (Tk 157250.00 and 143511.78/ha, respectively) but the treatment Zn₅B₁ Cu₁ kg/ha provided the second highest benefit cost ratio (11.86). On the contrary, the lowest gross return, gross margin and benefit cost ratio (Tk 58850.00, 49609.00/ha and 5.37, respectively) were contributed by Zn₀B₀Cu₀ kg/ha. Therefore, the two years experiment concluded that from the economic point of view the suitable fertilizer dose for onion cultivation is Zn₅ B₂ Cu₁ kg/ha (plus N ₁₀₀Px ₈₀K _10oS₂₀ kg/ha) in the soil under study and in its extrapolation area under the southern region of Bangladesh.
