Effect of Planting Time on Growth and Yield of Garlic (Allium sativum L.) Genotypes

Abstract

A field experiment was conducted at the field Laboratory, Horticulture farm, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh during the dry season (October to April) to evaluate the effect of planting time on the growth and yield of two garlic varieties. The experiment was laid-out with two factors, dates of planting (21 October, 6 November, 21 November and 06 December) and variety (BAU garlic-1 and BAU garlic-2) in Randomized Complete Block Design with three replications. Planting time had significant influence on growth and yield attributes as well as bulb yield of garlic. Plant height, leaf length, number of leaves, leaf and root dry weight, bulb diameter, number of cloves per bulb and bulb yield decreased with delay planting. The highest plant height (52.38 cm), leaf length (37.66 cm), number of leaves per plant (7.15), leaf dry weight (1.75 g), bulb diameter (3.89 cm), number of cloves per bulb (22.31), bulb yield per plant (16.42 g) and per hectare (8.13 t ha-1) obtained from 21 October planting. BAU garlic-2 was relatively better than BAU garlic-1 in terms of yield and yield attributes. The interaction effect of planting time and variety showed the highest bulb yield of both varieties from 21 October planting. Early planting of both varieties found better to get maximum yield of garlic.
