Here are some small scale agricultural productions that can be practiced for income and self employment.
These products are always been demanded by the ever increasing Nigerian population, yet not in abundance, these products are;

1) Apiculture: This is the keeping and maintenance of bee for commercial reasons. There are many products that can be obtained from bee keeping, one of which is the honey. Honey and other by products from bees are of high demand in Nigeria ranging from consumption as confectionery to medicinal consumption also for some industrial purposes. Honey is widely used for various purposes in the health sector.
Unlike many other agricultural production that need land acquisition, bee keeping doesn’t. In fact partnership can be done with some fruit farmers for housing of the bees, which can result in advantageous boost in harvest due to the pollinating activities of the bees.
The protective suit and bee hive can be manufactured locally to reduce cost. Other materials need include; smokers, buckets, jungle boots, wheelbarrows, basins, honey extractor, weighing scales and other packaging materials.
About 10 to 12 litters can be obtained from a hive.

2) Snail production: This is an agricultural production of snail. Snails are wide consumed through out the country, with the demand for snail well above 300 thousand tons yearly. The production of snail is considerably cheap and less difficult, hence, can be easily practiced. Snails are herbivores, so less cost on feeding, since they feed on leaves like banana leaves.
A wooden box provided with low acidic soil is used. The surrounding of this snailrey (a place where snail are bred and kept) is surrounded by deep, which look like gutter, this should be filled with water and little kerosene to keep ants off.
This production requires patience as snail takes time to mature, about 12 months. An average snail lay over 500 eggs which hatch in about 2 weeks and these snail in turn lay several eggs before maturity. You can imagine the profit that will be gotten from this prolific specie. This product are in high demand in many hotel restaurants and other food businesses.

3) Fish production: This has to do with production of fish for consumption. Fish are largely consumed in Nigeria. The production of fish can be done right at the back yard of your house. Though it needs attention to attain table size fish in less months (not more than six months), but the future profit worth the efforts put in. The feeding of fish should be done slowly and gradually, if not, some fish will have stunted growth, since they are weak to struggle for feed.
The production can be done in plastic tank of desirable size based on the stocking quantity, rather thab expenses on digging and maintenance of a sunken pond. The major problem is getting a good source of water which must be free from chlorine. They are fed with pelletized fish feed of the right mixture of ingredients, for quick growth. Also maggot feed can be used as supplementary. The market for fish is ever ready and the selling price, to a large extent, depends on the preservation and packaging of the product.

This can be small at start but can become big later. Not all millionaires are in the office but some are on the field working hard.
You can help by adding other lucrative agricultural enterprises.

I sell maggots, any quantity you want.....maggots are used in breeding fishes as they very nutritious......
