After the 2 seeds have picked up, you can separate them and plant them somewhere. Spacing; 80-100cm (1M) in the rows and 60-80 cm apart (roughly 1M). Manure; 500-100kg/acre during planting. Folia feeds can also be used Weeding’s; ensure your farm is free from weeds Pests and diseases and how to control Pests; insects can be controlled by spraying appropriate pesticides from any agro vet Diseases; stem rot & root rot can be controlled by monitoring water level and avoid planting of other crops that are prone to those diseases.
