Effect of vermicompost and sulphur on quality of garlic (Allium sativum L.) under semi arid conditions.
Keywords:
Bulb, volatile oil, nutrients, TSS, ascorbic acidAbstract
An experiment was carried out to study the suitable dose of vermicompost and sulphur for obtaining good quality bulbs of garlic (Allium sativum L.) cv. G-41. The experiment comprised of 16 treatment combinations with four levels of -1 -1 -1 each vermicompost (0, 2.5, 5.0 and 7.5 t ha ) and sulphur (0, 30, 60 and 90 kg ha ). The application of 5.0 t vermicompost ha -1 and 60 kg sulphur ha was found suitable in terms of quality and resulted in saving of 2.5 t/ha of vermicompost and 30 kg of S -1 -1 ha . Thus, application of 5.0 t vermicompost and 60 kg S ha to garlic crop was found significantly better for quality production of bulbs in respect to nitrogen, phosphorus, potassium, sulphur, TSS, ascorbic acid, crude protein and volatile oil content.
