INFLUENCE OF EARTHING UP ON JAPANESE BUNCH ONION (ALLIUM FISTULOSUM L.) CV. MOTO KURA

The study was conducted in the Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from December 2011 to May 2012 to find out the influence of earthing up on growth and yield of Japanese bunch onion (Moto kura). Three levels of earthing up viz. E₀: No earthing up; E₁­: Earthing up (once) ‍and E₂: Earthing up (twice) was set at the experiment following Randomized Complete Block Design with three replications. Tallest plant (60.4 cm) with maximum number of leaves (8.4), leaf area (334.7 cm2) and maximum weight of leaves/plant (80.5 g) were found from E₂. On the other hand, longest pseudostem (13.2 cm), maximum diameter of pseudostem (20.5 mm), maximum weight of pseudostem (28.8 g), highest yield/plot (2.88 kg) and highest yield/hectare (14.4 ton) was found from E₂. E₁ was statistically similar with the E₂ and E₀ provided least result in each parameters.
