Maize (zea mays) also known as corn is one among the profitable crops in Nigeria, it is a cereal plant of the Gramieae family of grasses that today constitutes the most widely distributed food in the world. When maize cultivation started in Nigeria, it was first cultivated as a subsistence crop, in small quantities for family survival only. As time went on maize farming changed its face and operations from subsistence farming to commercial farming. Today maize is planted in larger(commercial) quantities because of its profitability, economic value and the demand for the crop in the market.

One of the most popular agribusinesses is fish farming. Fish farming is a common type of aquaculture. Fish farming is highly exploited as it allows the production of a cheap source of protein. Today, the modern farm practice has made it possible to grow fish in the farms and control the input. Fish farming is easier to do than other kinds of farming as fish are not care-intensive, but only require food and proper water conditions as well as temperatures. The process is also less land intensive , even though Catfish is not the most popular fish in Nigeria, this fish species is by far the most cultivated in Nigeria. One thing good about catfish is that it is one of the easiest fish species to cultivate. So, people naturally flow in the direction of fish species they found to be the easiest to cultivate. If you are thinking of a business to start now, I recommend you start Catfish Farming. If you are an existing farmer and you are looking to expand your farm capacity, I’d encourage you to add fish farming to your line of business. Fish farming (especially catfish) is most compatible with poultry farming as you can use the poultry drops to produce the feed for your fish.

Cassava is the third-largest source of food carbohydrates in the tropics, after rice and maize. Cassava is a major staple food in the developing world, providing a basic diet for over half a billion people. It is one of the most drought-tolerant crops, capable of growing on marginal soils. Nigeria is the world's largest producer of cassava, while Thailand is the largest exporter of cassava starch. The cassava root is long and tapered, with a firm, homogeneous flesh encased in a detachable rind, about 1 mm thick, rough, and brown on the outside. Cassava is a calorie-rich vegetable that contains plenty of carbohydrates and key vitamins and minerals. Cassava is a good source of vitamin C, thiamine, riboflavin, and niacin. The leaves, which are also edible if a person cooks them or dries them in the sun, can contain up to 25% protein.
