Effect of nitrogen and sulphur levels on growth and yield of garlic (Allium sativum L.).

A study was conducted in the College of Horticulture, Mandsaur during the years 2007- 2008 during the rabi season (Winter, Oct.-March). The main aim of this experiment was to enhance the productivity of garlic through assessing the effect of different levels of nitrogen and sulphur. The experiment consisting of 4 levels of nitrogen (50, 100, 150 and 200 kg ha -1 ) and 4 levels of sulphur (0. 20, 40 and 60 kg ha -1 ) were applied as basal dose and top dressing. Application of 200 kg nitrogen ha -1 significantly increased the plant height (cm), number of leaves per plant, neck thickness (cm), bulb diameter(cm), number of cloves per bulb, fresh weight of 20 cloves (g), dry weight of 20 cloves (g), fresh weight of bulb (g), dry eight of bulb (g) and bulb yield (q ha -1 ). Among various levels of sulphur tried (60 kg ha -1 ) exhibited the best growth and yield attributes. Significantly higher yield of garlic was obtained with the treatment combination (200 kg n ha -1 + 60 kg S ha -1 ).
