An experiment was carried out at Horticultural farm, Sher-e-Bangla Agricultural University, Dhaka-1207, during the period of the October, 2006 to March 2007, to investigate the different potassium levels on carrot growth and yield benefit ratio. Four mulch materials viz. K0, 0 Kg K2O (control); K1, 180 Kg K2O per ha; K2, 200 Kg K2O per ha and K3, 220 Kg K2O per ha were used in this experiment. The experiment was done with randomized completely block design (RCBD) with three replications. The seeds of carrot cv. New Kuroda (a Japanese varity) were used in the experiment. Carrot 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. 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. However, potassium was applied at the rate of 0, 180, 200, 220 kg K2O per hectare respectively in the form of muriate of potash as per treatments in different plots. 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 was maintained 1:1ratio 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. The marketable roots were weighted (marketable yield = gross yield – non marketable yield) and expressed in kg. 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. The net fields benefit (NFP) and cost benefit ration (BCR) was calculated. The net benefit was calculated by subtracting the total variable cost from the total benefits from each treatment combination. The variable costs mention include, seed, family labour, hired labour, tractor hiring, transportation, fuel, empty basket, fertilizer, and agrochemicals. While Fixed cost includes: depreciation of fixed asset and rent on land. 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.
