control weeds
Sir,
Fist step to erradicate grass is to prevent falling of sunlight to soil.
In you case is concerned plse cut the grasses first and cultivate the land.
Then grow hybrid Napier 1 m x 1m spacing .in between the rows grow maize/sorghum
another option
alone grow dual pupose sorghum give chemical fertilizers as per recommendation. It will prevent the light penetration , and the weeds become weaker.
Thank you
