Effect of Planting Time and Planting System on the Growth and Yield of Some Garlic Germplasm

Abstract

The vegetative growth, yield attributes and yield of garlic depends on timely planting, planting system and high yielding cultivar. The purpose of this experiment was to investigate the effects of planting time, planting system with variety on the growth and yield of garlic germplasm. Two experiments were performed during the study, and the experiments were laid out in Randomized Complete Block Design (RCBD). Four planting time (such as 26 October, 9 November, 20 November and 10 December), two factors for planting system (such as zero tillage and dry land) and four varieties (such as BAU garlic-1, BAU garlic-2, BAU garlic-3 and G-51) were considered during the experiments. The results revealed that the planting time had significant influence on growth parameters, yield attributes and yield of garlic. The highest values of growth parameters as well as bulb yield (10.33 t/ha) were obtained at 26 October whereas the lowest values were recorded at 10 December resulting bulb yield (8.47 t/ha). On the other hand, the planting system had also significant influence on the vegetative growth and yield of garlic. The highest values of growth characters, yield attributes and yield of garlic was found in zero tillage compared to dry land. BAU Garlic-3 was provided the highest growth as well as bulb yield among other three varieties. It was also noticed that, the combined treatment of zero tillage and variety of BAU Garlic-3 gave the highest values of growth and yield attributes as well as bulb yield (8.80 t/ha) parallel with other combined effects. Results expressed that the early planting and the combination of zero tillage and BAU Garlic-3 variety has given the profound effects on the growth parameters as bulb yield of garlic.
