General crop situation

The overall crop performance in terms of growth and development is progressing satisfactorily across the country. However, due to uneven rainfall distribution at the beginning of the season, the phenological phases of crops varies from region to region across the country. Some farmers started harvesting maize and groundnut to secure good price as early harvest attracts good price from the market. However, the groundnuts harvested and taken to the market are not fully matured. Meanwhile, according to all Regional Agricultural Directorates (RADs) in the country, the area put to production this year for early millet, maize and rice has increased as compared to last year, this is mainly due to the input support received from Agricultural Projects at the start of the cropping season and subsidized fertilizer to farmers.
