It is easy to establish a Push-Pull plot using Brachiaria grass

Brachiaria is a good alternative to Napier grass when used in push-pull plots since it is drought tolerant and not prone to diseases. Brachiaria grass is more nutritious, possessing 12 per cent protein at harvest unlike Napier, whose protein content diminishes after about four months.

Oasis garden ensures vegetable supply

Rainfall is the main source of water for irrigation for many farmers. 

Biological methods of pest control that protect environment

Biopesticides and fungicides protect humans, animals and the environment. Unlike chemicals, biopesticides and fungicides kill only the targeted pests or microorganisms. Moreover, they are cheap and do not leave any harmful residue in the soil, water or the air.
