Abstract/ Executive Summary:

The present experiment was conducted at Spices Research Center, Shibganj, Bogra during the period from October 2007 to March 2008 to determine the optimum dose of Boron and Sulfur for better yield of garlic. Five levels of boron viz. 0, 0.5, 1.0, 1.5 and 2.0 Kg/ha and five levels of sulfur viz. 0, 20, 40, 60 and 80 Kg/ha were used in the study. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. It was found that 1 kg B/ha gave the highest bulb yield (9.72 t/ha). Sulfur had also significant effect on growth and yield of garlic. The highest bulb yield (9.69 t/ha) was found with 60 Kg/ha S application. Interaction effect of boron and sulfur was significant on bulb yield though exhibited insignificant variations in some growth parameters. The maximum bulb yield (10.64 t/ha) was obtained from the treatment combination of 1Kg B/ha and 40 Kg S/ha.

Keywords: Garlic, Boron, Sulfur, Growth and yield

Location: Spices Research Center, BARI, Shibganj, Bogra

Start Date: 01-10-2007

End Date: 30-04-2008

Program Area: Crop-Soil-Water Management

Commodity: Garlic

Objectives:

To study the effect of different level of boron and sulfur on growth and yield of garlic.

Methodology:

The experiment was conducted at Spices Research Center, Shibganj, Bogra during the period from October 2007 to March 2008 with a view to determine the optimum dose of Boron and Sulfur for better yield of garlic. BARI Rashun-1 was used in this experiment. The initial soil sample of the experimental field was calculated and analyzed to know the nutrient status of the soil. Five different levels of boron viz. 0, 0.5, 1.0, 1.5 and 2.0 Kg/ha and five levels of sulfur viz. 0, 20, 40, 60 and 80 Kg/ha were used in this experiment. In addition a blanket dose of cowdung, urea, TSP and MP @ 217, 267, and 333 Kg/ha, respectively were used in this study. The two-factor experiment consisting of 16 treatment combinations was laid out in Randomized Complete Block Design factorial (RCBD -factorial) with three replications. The size of unit plot was 1.5m x 1m and spacing was 15 cm x 10 cm. The entire amount of cowdung, TSP, MP and half of urea were applied during land preparation. Remaining urea was applied in 2 equal splits at 25 and 50 days after planting. Boron and sulfur were applied as per treatment during final bed preparation. Intercultural operations were done as and when necessary. The crops were planted on 20 October 2007 and harvested on 10 March 2008. Data were recorded on plant height, number of leaves per plant, fresh weight of bulbs (g), bulb diameter (cm), number of cloves per bulb, yield of bulb per plot (g) and bulb yield (t/ha).

Achievement/Findings:

The application of boron had significant variation on plant height, fresh weight of bulbs, number of cloves per bulb and bulb diameter. The highest plant height (67.67 cm) was found from 0.5 Kg B/ha and the lowest (64.33 cm) was found from 0 Kg B/ha. The maximum (30.36) and the minimum (26.63) number of cloves per bulb were counted from the treatment of 0.5 Kg B and 0 Kg S/ha, respectively. The highest bulb diameter (3.70 cm) was found from 1.0 Kg B/ha and the lowest (3.31 cm) was obtained from 0 Kg B/ha. Significantly the highest fresh weight of bulb (19.73 g) per plant was recorded from 1.0 Kg B/ha and the lowest (18.23 g) was found from 2.0 Kg B/ha. The highest fresh weight of bulb (20.13 g) was obtained from 40 Kg S/ha and the lowest (17.50 g) was found from 80 Kg S/ha. Significantly the highest bulb yield (9.69 t/ha) was observed from 60 Kg S/ha and the lowest (8.57 t/ha) was found from 0 Kg S/ha. The highest (70.53) plant height was found from the treatment combination of 0.5 Kg B and 60 Kg S/ha and the lowest (58.33) was obtained from 0 kg B and 0 Kg S/ha.The highest number of cloves (33.47) per bulb was found from the treatment combination of 0.5 Kg B and 60 Kg S/ha and the lowest (21.00) was obtained from 0 kg B and 0 Kg S/ha. The highest bulb yield (10.64 t/ha) was obtained from 1Kg B and 40 Kg S/ha. The highest net return Tk. 332776 was obtained from the combination of 1.0 Kg B/ha and 40 Kg S/ha with a BCR of 4.59. The lowest (Tk. 1921815) net return was obtained from 1.5 Kg B/ha and 40 Kg S/ha with a BCR of 1.29.
