Husbandry
Animal husbandry is the special branch of agriculture concerned with animals that are raised for meat, fibre, milk, eggs, or other products. It includes day-to-day care, cultivation, selective breeding and the raising of crops and animals.
Cultivation of cereals
| MAIZE (Zea mays) | RICE (Oryza Sativa) | |
| Description | Maize also called corn is a member of the grass family (Gramineae). It produces grains, use as food by human beings and livestock. The seed/fruit is called a caryopsis. | Rice is a member of the grass family (Gramineae). The seed/ fruit is called a caryopsis |
| Varieties/cultivar | Sweet maize, flint maize, dent maize, flour maize and popcorn | Swamp rice (Toma) and upland rice (Agbede). |
| Land preparation | Clearing the land and making ridges either manually or mechanically. | Clearing the land and making ridges either manually or mechanically. |
| Climatic requirement |
Temperature – 260C-300C, Rainfall – 75cm-150cm per annum | The temperature of 200c, Rainfall of 75cm-120cm for upland rice and over 250cm for swamp rice. |
| Soil requirement | Sandy-loamy soil of PH 6-7 | Loamy-clayey soil. |
| Method of propagation | By seeds | By seeds |
| Planting date | Early maize – March/April Late maize – July/August | South – April/May, North – August/ September. |
| Planting | It can be done manually using cutlass or mechanically by planter at 2-3 seeds per hole. | Planting can be done by broadcasting, sowing or drilling. |
| Seed rate | 20-30kg per hectare of land | 65kg per hectare at 2-3 seeds per hole. |
| Spacing | 80cm between row and 30cmwithin row | 25-30cm apart depending on varieties. |
| Cultural practices | Supplying, thinning, weeding fertilizer application, control of pests and diseases. | Supplying, thinning, weeding fertilizer application, control of pests and diseases. |
| Maturity period | 90-120 days after planting depending on varieties. | 4-7 months depending on varieties. |
| Harvesting | Harvesting can be done manually with hand or using a hand sickle and mechanically using a combined harvester. | Redheads of rice are harvested with a knife, sickle or combined harvester. |
| Processing | It is eaten either boiled, roasted or processed into corn flour or corn flakes. | Sun drying, threshing, winnowing, per boiling, hulling and polishing. |
| Uses | It is consumed by man and farm animals and as a raw material in brewery industries | It is consumed by man and farm animals. |
| Storage | Dried cobs are stored in cribs, rhombus or a fireplace, grains stored in a silo. | Processed form in silos or jute bags. |
