Abstract/ Executive Summary:

A field experiment on coriander (Coriandrum sativum L.) was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during February 2009 to April 2009 to find out the optimum seed rate in relation to sowing methods for maximizing foliage yield of coriander. Four genotypes (CS001, CS002, CS003 and CS008) and three sowing methods (continuous line sowing spaced at 10 cm, 20 cm and broadcast method) and three levels of seed rate (30, 40 and 50 kg/ha) were used as treatment variables.. The result showed that genotype CS003 singly gave the maximum plant height, number of leaves/plant, single plant weight and plant weight/m2 and thus gave the highest foliage yield/ha. Line sowing (10 cm), broadcast method with seed rate @ 50 kg/ha independently produced the maximum foliage weight/m2 and foliage yield/ha. Line sowing (10 cm) with 50 kg/ha seed rate produced the highest foliage yield in case of CS001, CS002 and CS003 genotypes, which was closely followed by broadcast method and the same seed rate. But line sowing (10 cm) as well as broadcast method coupled with 40 kg/ha seed rate gave better foliage yield in genotype CS008.

Start Date: 00-02-2009

End Date: 00-04-2009

Program Area: Crop-Soil-Water Management

Commodity: Coriander

Objectives:

To find out an appropriate seed rate in relation to sowing methods for higher foliage yield of coriander.

Methodology:

The experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur during February 2009 to April 2009. The initial soil samples of the experimental field were collected and analyzed following standard laboratory procedures. The soil was slightly acidic (pH 6.2) having low organic matter content (1.96%). The content of total N was very low. Available P, S and exchangeable K, Ca and Mg were also low. The four genotypes (CS001, CS002, CS003, and CS008) collected from Siddique Bazzar, Dhaka but the genotype CS008 was collected from Tangail district. These materials showed better performances in respect of foliage production in the earlier experiment. Four genotypes (CS001, CS002, CS003, and CS008), three sowing methods (continuous line sowing spaced at 10 cm, 20 cm and broadcast method) and three levels of seed rates (30, 40 and 50 kg/ha) were used as experimental material. The experiment was laid out in a split-split plot design with three replications. Genotypes were assigned in the main plot, three sowing methods were placed in sub-plots and three seed rates in sub-sub plot. The unit plot size was 3 m ×1 m. The land was fertilized with 5 tons, cowdung, 40 kg N, 11 kg P, and 25 kg K per hectare. The entire amount of cowdung, phosphorus from TSP, and potassium from MoP and one- half of nitrogen from urea was applied during final land preparation. The rest of the nitrogen was top-dressed at 20 days after sowing. The seeds (fruits) were rubbed for separating the two mericarps (seeds) and were soaked in water for 24 hours to enhance germination. Seeds were also treated with Bavistin at the rate of 2 g per kg of seeds before sowing. The seeds of each genotype were sown maintaining experimental sowing methods and seed rate on 29 February 2009. The weeding was done after 20 days after sowing (DAS). Plant thinning was not done for the crop. For uniform germination water was given to the plots every three days by water can with fine mashed nozzle till germination. Besides, two irrigations were given to the crop at 25 and 32 days after sowing. Harvesting of plants was done by cutting just beneath the soil when few plants were seen to bolt depending upon the genotypes. Data were collected from the inner rows of each plot to avoid the border effect. In each unit plot 10 plants were selected randomly for recording data on plant height (cm) and yield attributes. Plot yield was converted to per hectare yield. The data were compiled properly and analyzed statistically and mean comparison was done following the Duncan’s New Multiple Range Test (DMRT) at 5% level of probability.

Achievement/Findings:

It might be concluded that the seed rate of 50 kg/ha coupled with either continuous line sowing (10 cm spaced) or broadcast method with the genotype CS003 gave the highest foliage production in coriander.
