Abstract/ Executive Summary:

The investigation was carried out to find the effect of plant spacing on growth and yield of two lines of garlic under dry land condition at BAU, Mymensingh during 2005 to 2006. The two-factor experiment had 4 Plant spacing: 10cm x 10cm (150 plants/1.5 m²), 15cm x 10cm (100 plants/1.5 m²), 15cm x 15cm (66 plants/1.5 m²) and 20cm x 10cm (75 plants/1.5 m²) and 2 garlic lines: G2 and G19. The experiment was conducted in randomized complete block design (RCBD) with 3 replications. The results revealed that the plant height, number of leaves per plant, fresh weight of bulb, length and diameter of bulb, total number of cloves, yield per plot and yield per hectare were significantly influenced by the treatment of the experiments under study. Results showed that G19 was the best for yield and yield contributing characters than G2. Yield and yield contributing characters were found to be maximum in garlic lines G19. Garlic line G19 gave the highest yield per plot (2.02 kg) and yield per hectare (16.07 t/ha). The lowest yield per plot (1.65 kg) and yield per hectare (13.09 t/ha) was observed with garlic line G2. The treatment of 15cm × 15 cm spacing gave the highest yield per plot (2.03 kg) and yield per hectare (16.21 t) and 10cm × 10cm spacing gave the lowest yield per plot (1.60 kg/plot) and yield per hectare (13.16 t). The combined effect of garlic lines and plant spacing revealed significant variation in bulb yield and various yield components. The garlic genotype G19 gave the highest (18.67 t/ha) yields at the closest spacing (10 cm × 10 cm) at Mymensingh.

Program Area: Crop-Soil-Water Management

Commodity: Garlic

Objectives:

1. To study the effect of plant spacing on growth and yield of two lines of garlic under dry land condition at BAU, Mymensingh was undertaken to find out the optimum plant density for garlic.

Methodology:

The present investigation was carried out to find the effect of plant spacing on growth and yield of two lines of garlic under dry land condition at BAU, Mymensingh during 2005 to 2006. The two-factor experiment had 4 Plant spacing: 10cm x 10cm (150 plants/1.5 m²), 15cm x 10cm (100 plants/1.5 m²), 15cm x 15cm (66 plants/1.5 m²) and 20cm x 10cm (75 plants/1.5 m²) and 2 garlic lines: G2 and G19. The experiment was conducted in randomized complete block design (RCBD) with 3 replications. The unit plot size was 1.5m x 1m; total number of treatments: 4 x2 =8; Total number of unit plots: 8x3 = 24; Date of planting: 9 Nov, 2005; Date of harvesting: 29 March, 2006. Data were recorded on yield and yield contributing characters on height of plant, no. of leaves per plant, fresh weight of bulb diameter of bulb, length of bulb, no. of cloves per bulb, yield of bulb per plot and yield of bulb per hectare. Intercultural operation were done as and when necessary. The difference between the treatment means was judged by Least Significance Test (LSD).

Achievement/Findings:

A remarkable combined effect was observed between the different plant spacing and different lines of garlic on all the parameters studied different days after planting. The tallest plant (80.50cm) and the maximum number of leaves (8.60) per plant were found in 15 cm×15 cm with garlic line G19 120 DAP and the shortest plant (26.40 cm) and the minimum numbers of leaves (3.60) were obtained from 10 cm×10 cm with garlic line G2 30 DAP. The highest fresh weight of bulb per plant (39.00g), length (4.70cm) and diameter (4.40cm) of bulb, number of cloves per bulb (31.60) were obtained from 15 cm×15 cm with garlic lines G19 and the lowest values were found on all the above mentioned parameters from 10 cm×10 cm with garlic lines G2 .The maximum yield per plot (2.52 Kg) as well as yield (18.67 t/ha)were obtained from 10 cm×10 cm with garlic lines G19 and the minimum yield were found from 15 cm×15 cm with garlic line G2. Garlic line G19 and 10 cm × 10 cm plant spacing produce the maximum yield and also show the best performance in respect of all the yield contributing characters studied .So garlic lines G19 and 10 cm × 10 cm plant spacing may be used in garlic production to get maximum yield.
