The country’s irrigation-based farming is still limited. Of the total land area under agriculture, 2.9 million ha, irrigation accounts for only 4% but contributes to 3% of the GDP and provides 18% of the value of all agricultural produce, demonstrating it’s potential in increasing agricultural production and productivity. Irrigated agriculture is carried out mainly in irrigation schemes and in large scale irrigation of crops such as rice and coffee. Individual farmers have developed their own systems of irrigation especially for export crops such as coffee and horticulture.
Drip irrigation will be good option if underground water is of good quality and limited.
Drip and Sprinkler. But, besides irrigation please think about crop-fallow rotations, minimum/zero tillage, cover cropping and and use of mulch to retain water and improve soil quality.
I agree with others, drip irrigation scheduling is suitable for plants .
Depending on the spatial distribution of rainfall and topography, surface irrigation system through storage will also work, apart from the suggestions given already.
