Influence of Different Types of Manure and Clove Size on the Growth and Yield of Garlic (Allium salivum L)

Abstract

In order to determine the effects of various types of manure and clove size on the development and productivity of garlic, an experiment was carried out at the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka, between November 2021 and April 2022. The experiment consisted of three sizes of garlic cloves (Viz. C1=small (50gm/100 cloves), C2=medium (70gm/100 cloves), C3=large (90gm/100 cloves)) and four levels of manure (Viz. M0= Control (No manure), M1= Cowdung (15t/ha), M2= Vermicompost (6t/ha), M3= Mushroom spent compost (6t/ha)). The two-factor experiment was carried out in Randomized Complete Block Design (RCBD) with three replications and 12 treatments. Growth and yield of garlic were influenced by the different clove sizes. The C3 treatment had the most leaves (12.77), the largest bulb diameter (4.11 cm), the most cloves per bulb (25.49), the largest clove diameter (1.35 cm), the largest weight of 10 cloves per bulb (13.5 g), and the highest bulb output per hectare (9.43 ton). The growth and yield of garlic were significantly impacted by different level of manure. The M3 treatment produced the highest number of leaves (12.45), maximum bulb diameter (3.73 cm), highest number of cloves per bulb (24.44), highest diameter of cloves per bulb (1.08 cm), highest weight of 10 cloves per bulb (11.83 g), and highest bulb output per hectare (9.92 ton). The highest bulb yield (11.42 ton/ha) was obtained from M3C3 treatment combination, while the lowest bulb yield (5.49 ton/ha) was obtained from M0C1 treatment combination. So, it can be revealed that the M3C3 treatment combination appeared to the best for achieving the higher yield of garlic.
