Agronomic Management

Agronomic Management
To full fill the observed gap for the future it needs a focus on the adaptation of improved varieties to the remaining potential areas, fertilizer nutrient management
More importantly, lack of improved varieties and absence of any responsible agents who produces and distributes the improved seed materials to the growers were the main bottleneck problems at the country level. However, nowadays, due to the presence of awareness for its nutritional and health benefit as well as for its economic requirements, different encouraged practices like an adaptation of different cultivars to the various agro-ecologies, uses of an appropriate agronomic management, improvements of crop water requirements, plant fertilizer requirement and rate optimization, disease and insect pest identification and its mitigation activities are underway by various research centers and higher learning institutes.
As a general, the government should have to give a due attention to onion production to get all the possible advantages from of the crop. Also, research centers and higher learning institutes should have adapted to the growers with its full packages and should strive to develop appropriate cultivars for different agro-ecologies of the country. To full fill the observed gap for the future it needs a focus on the adaptation of improved varieties to the remaining potential areas, fertilizer nutrient management which includes the micro and macro nutrients also needs a great attention to produce the maximum yield from the crop. The water use efficiency improvement further needs a critical attention to overcome the problem regarding crop in the country.
Conflict of interest. Regarding the publication of this manuscript, there is no any conflict of interest.
