Colombo (LNW): The Department of Agriculture is expected to immediately submit a report on the cultivation of big onions in the country to the Ministry of Agriculture, in the backdrop where the b-onion cultivation has largely failed for the past seven – to – eight years. The b-onion cultivation, which was successfully carried out in Sri Lanka for a long period of time, is now failing and a report, therefore, is expected immediately, emphasised subject Minister Mahinda Amaraweera. The Department of Agriculture, accordingly, has been assigned to probe the matter and submit a report to the Ministry as soon as possible. In the meantime, Ministry data pointed out that the annual requirement of b-onions in Sri Lanka is 300,000 metric tonnes, and the amount of b-onions imported during the period is 131,795 metric tonnes due to the national production being only 4,716 metric tonnes.
