Abstract/ Executive Summary:

An experiment was conducted in Department of Horticulture, Sher-e-Bangla Agricultural University, Dhaka, during October 2006 to March 2007, to evaluate the growth and yield performance for understanding cost benefit ratio. The study consisted of four levels of mulch viz. M_0, Control; M₁, Black polythene; M₂, Water hyacinth and M₃, Saw dust. The experiment was laid out with randomized complete block (RCB) design with three replications. However, all of growth and yield related traits showed the significant variation. The highest (36.3 t/ha) marketable yield was obtained from M₁, while the minimum (31 t/ha) marketable yield was recorded from M₀. In case of economic analysis, black mulch showed the maximum (2.1) cost benefit ratio and minimum (1.7) found in control (M₀) for economic yield of carrot production.

Keywords: Mulching, Yield and cost benefit ratio, Carrot.

Location: Horticultural farm, Sher-e-Bangla Agricultural University, Dhaka-1207

Start Date: 00-10-2006

End Date: 00-03-2007

Program Area: Crop-Soil-Water Management

Commodity: Carrot

Objectives:

To analyze the yield of carrot as influenced by different mulch materials with cost benefit ratio.

Methodology:

An experiment was accomplished at Horticultural farm, Sher-e-Bangla Agricultural University, Dhaka-1207, during the period of the October, 2006 to March 2007, to evaluate the growth and yield benefit ratio different mulch material. Four mulch materials viz. M₀, No mulch (control); M_1, Black polythene; M₂, Water hyacinth and M₃, Saw dust were used in this experiment. The experiment was laid out with randomized completely block design (RCBD) with three replications. The seeds of carrot cv. New Kuroda (a Japanese varity) were used in the experiment. The seeds of Snow Brand Co. Ltd., Tokyo, Japan were collected from Nadim Seed Store, Siddique Bazar, Dhaka. Seed was directly sown in the seedbed. Before sowing, the seed were soaked in water for 24 hours and then wrapped with a piece of thin cloth prior to planting. Then the moistened seeds were spread over polythene sheet for two hours to dry out the surface water. Shallow furrows with 1.5 cm depth were made at a distance of 15 cm along the rows spaced at a distance of 25 cm. During germination, watering and observation were followed regularly. The experimental plot was 182 m² (14m x 13m) which was divided into three equal blocks and each block was then divided into 16 unit plots. The size of each plot was 1.5m x 1m and maintaing spacing 25 x 15 cm. and each plot consisted of 40 plants. Thus, there were 48 (16 x 3) unit plots altogether in the experiment. During the experiment, the soil was maintain to apply equal amount of well decomposed cowdung and inorganic nutrient at N:P:K was maintained 1:1:1 ratio and, watering and weeding were followed by visual observation. Data were collected with different parameter like - Length of root/plant, diameter of root/plant, Fresh weight of leaves/plant, Fresh weight of root/plant, Percent dry matter of roots, Percent dry matter of leaves, Cracked roots/plot, Rotten roots/plot, Branched roots/plot, Total yield of roots/plot, Total yield of roots/h, Marketable yield of roots/plot, Marketable yield of roots/h. Economic analysis was also measured to find out the cost benefit ratio of mulch material for carrot production. Hence, cost and return analysis was done. Digital slide caliper was used for recording diameter and centimeter and three layers of data were averaged by the determining of plant attributes character. Data were calculated for statistical analysis in MSTAT-C software program. Mean comparisons was conducted and analysis of variance for each of variety was represented by F-test. Differences between varieties were evaluated by Least Significance Difference Test (LSD) at 5% level of significance.

Achievement/Findings:

Present study revealed the significant variation with different mulch materials for carrot production. Black mulch (M₁) showed the best treatment for growth and yield for carrot production. Results also suggested that black mulch was best for cost benefit ratio for commercial growers.
