Abstract/ Executive Summary:

An experiment was conducted at the Horticulture Farm, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur, Bangladesh to find out the effects of mulch and different manures and fertilizers on the yield components and quality of carrot (Daucus carota L.). Twelve treatment combinations were evaluated in two factors Randomized Complete Block Design (RCBD) with three replications. Different doses of manures and fertilizers viz. F₀ = Control, F₁ = Cowdung (CD) @ 10 t ha^-1, F₂ = Mustard Oil Cake (MOC) @ 0.25 t ha^-1, F₃ = Cowdung (CD) @ 5.0 t ha^-1 + Mustard Oil Cake (MOC) @ 0.125 t ha^-1, F₄ = Urea @ 326.08 kg ha^-1 + Triple Super Phosphate (TSP) @ 93.75 kg ha^-1 + Muriate of Potash (MoP) @ 200 kg ha^-1 and F₅ = Cowdung (CD) @ 5 t ha^-1+ Urea @ 163.04 kg ha^-1 + Triple Super Phosphate (TSP) @ 46.87 kg ha^-1 + Muriate of Potash (MoP) @ 100 kg ha^-1 were applied under mulched (M₁) and non-mulched (M₀) conditions. Results from our study revealed that maximum fresh weight (3.57 kg plot^-1), individual root weight (101.90 g), root length (14.64 cm), root diameter (3.27 cm), total yield (23.78 t ha^-1), marketable yield (20.53 t ha^-1) and beta-carotene content (8.78 mg 100^-1 g) were recorded from F₅ treatment. The mulching also had a significantly positive effect on maximizing the root yield components as well as beta-carotene contents over non-mulched treatment. On the other hand, the interaction effect of M₁F₅ performed superior in producing yield components and beta-carotene content of root compared to other combinations. The highest marketable yield (25.10 t ha^-1) along with the best economic gross return (TK. 2,47,167 ha^-1) and the benefit-cost ratio (2.91) were also noted from M₁F₅. It was concluded that organic and inorganic sources of nutrients along with mulch effectively increase the carrot yield than the sole application of higher doses of manures and fertilizers.

Objectives:

To study the effect of inorganic fertilizers and organic manures with mulched and non-mulched conditions on root yield of carrot.

Methodology:

The experiment was set up at the central research farm and laboratory of Horticulture, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh during the period of November 2014 to March 2015. The soil of the experimental area was Non- Calcareous Brown Floodplain with very low organic matter content (OM: 0.70%) and slightly acidic soil condition (pH: 6.3). The macronutrients in the experimental soil were very low to low in condition (total N: 0.04%, available P: 12.32 ppm, exchangeable K: 0.10 me 100^-1 g soil, exchangeable Ca: 1.02 me 100^-1 g soil, exchangeable Mg: 0.59 me 100^-1 g soil, available S: 30.88 ppm); whereas the micronutrients and cation exchange capacity were low to medium in condition (available Zn: 0.80 ppm, available B: 0.28 ppm, and CEC: 4.1 me 100^-1 g soil). Twelve treatments were performed under a two factors Randomized Complete Block Design with three replications. A mulch of rice straw (M₁) was compared without mulch or control (M₀) and different manures and fertilizers (6 levels) viz., F₀= Control, F₁ = CD @ 10 t ha^-1, F₂ = MOC @ 0.25 t ha^-1, F₃ = CD @ 5 t ha^-1 + MOC @ 0.125 t ha^-1, F₄ = Urea @ 326.08 kg ha^-1 + TSP @ 93.75 kg ha^-1 + MoP @ 200 kg ha^-1 and F₅ = CD @ 5 t ha^-1+ Urea @ 163.04 kg ha^-1 + TSP @ 46.87 kg ha^-1+ MoP @ 100 kg ha^-1 without manure and fertilizer (F₀). The treatment-wise required amounts of manures were applied during the final land preparation. The fertilizers (TSP and MoP) were applied at sowing time. Urea was applied in two equal splits; one after seedling emergence and another after 30 days after sowing. New Kuroda, a Japanese variety of carrots was used as a test crop. The size of the unit plot was 150 cm x 100 cm with a distance of 50 cm between blocks and each plot. The mulch of rice straw was provided immediately after the emergence of the seedling maintaining a thickness of 10 cm (3 kg plot^-1). The intercultural operations, as well as pest management, were done whenever necessary without any irrigation from seedling emergence to harvesting (only flood irrigation was applied before sowing). The crop was harvested depending upon the attaining good size of the root. The data were collected from the 10 randomly selected plants. The percent dry matter content of root was calculated by using the following formulae: % Dry matter = Dry weight of root/Fresh weight of root × 100. The length of the root was measured in centimeters (cm) with a meter scale. The diameter of roots was measured in centimeters after harvest following the middle portion of the root. The number of cracked, rotten, and branched roots were counted separately during harvest. Then, the percentage was calculated from the number of total roots. The equal cost was considered in the study which was analyzed in order to find out the most economic treatment of mulch and fertilizers. All input costs include the cost for the lease of land and interests on running capital were considered in computing the cost of production. The interests were calculated @ 13% for six months. The market price of carrots was considered for estimating the cost and return. Analyses were done in detail according to the procedure. The benefit-cost ratio (BCR) was calculated as follows: BCR = Gross return (Tk. ha^-1)/Total cost of production (Tk. ha^-1) × 100. The data obtained for different characters were statistically analyzed by the “MSTAT-C” program to find out the significance by evaluating the analysis of variance. The significance of the difference among the treatment combinations means was estimated by the Duncan’s Multiple Range Test (DMRT) at a 5% level of probability.

Achievement/Findings:

The mulch performed comparatively more pronounced in quality and yield parameters compared to non-mulch conditions. So, various mulch materials like water hyacinth, sawdust, green leaves like banana leaves may be used for further comparison. Among the manures and fertilizers amendment in this study, cowdung @ 5 t ha^-1 along with other inorganic sources of fertilizers like urea @ 163.04 kg ha^-1, TSP @ 46.87 kg ha^-1, and MoP @ 100 kg ha^-1 under mulched condition showed better in producing total as well as marketable yield of carrot. Considering the overall results, the treatment combination of M₁F₅ was the best option for carrot cultivation profitably in this area. The addition of organic manures may be the successful and sustainable nutrient management for improving soil fertility that will be beneficial for the farmers to cultivate the next crop.
