Effect of Organic Manure and Mulching on the Growth and Yield of Carrot (Daucus carota L.)
Asian Journal of Research in Crop Science,
An experiment on effect of organic manure & mulching on the growth and yield of carrot was conducted at the farm of Sher-e-Bangla Agricultural University, Dhaka during the period from November 2017 to February 2018. The research consisted in Randomized Complete Block Design (RCBD) with three replications under a factorial arrangement (of two factors), with Four levels of organic manure, as the factor A and four mulches such as factor B. Organic manure and mulching influenced significantly (p=0.05) all the studied variables. In case of organic manure the maximum plant height (44.55 cm) root length (14.73 cm), root diameter (4.11 cm), root weight (124.50 g), root yield (24.90 t/ha) and marketable root yield (23.85 ton/ha) were recorded from O2 (Vermicompost) treatment. In case of mulches, maximum plant height (44.81 cm), root length (15.20 cm), root diameter (3.91 cm), root weight (117.85 g), root yield (23.57 t/ha) and marketable root yield (21.95 t/ha) found in M2 (Black polythene) treatment. And the combined effect of the highest root yield (29.06 t/ha) was obtained from O2M2 (Vermicompost + black polythene) and lowest (13.20 t/ha) from O0M0 (control). So, it can be concluded that 10 ton/ha vermicompost with black polythene mulch was the best for carrot cultivation. The highest gross return (Tk. 563200), net return (Tk. 446355) and BCR (4.82) were obtained from the treatment combination from O2M2 where the lowest gross return (Tk. 207800), net return (Tk.112755) were obtained from O0M0 and lowest BCR (1.67) from O1M0.
