Advantages & Disadvantages of crop Rotation In Nigeria

Crop rotation is the practice of growing a series of different types of crops in the same area in sequential season. it is even practiced here in Nigeria and also in other parts of African countries.

Crop rotation helps reduce soil borne diseases, pest management is another benefit. Planting the same crop year after year allows pests to build up, requiring more pesticide use, which adds up to more cost.

So below are 10 Benefits Of Crop Rotation.

1.Crop rotation is helpful in enhancing the nutritional status of soil, for example after growing rice in the field we can take pulse crop that will enhance the nitrogen content in soil by fixing atmospheric nitrogen.

2. Crop rotation also prevent the plants from disease pathogen, this can be achieved by growing non host plants.

3. It also prevent the crops from insects.

4. It is also helpful in reducing weeds present in the field.

5. It also increase soil nutrient cycle and physical properties of soil.

6.Crop rotation can improve soil structure and fertility by alternating deep-rooted and shallow-rooted plants…

7.Crop rotation reduce soil erosion and water runoff and it also mitigates the build-up of pathogens and pests that often occurs when one species is continuously cropped.

8.Stops or slows the soil from being depleted of necessary organic creatures and foods.

9.All which are absolutly necessary for the survival of all of us and the animals we share the world with.

10.Crop rotation makes use of the different nutritional requirements, pests, weeds and risk profile of normally annual crops.

You can grow the same crop year after year, but ther tendency is that the yield declines. With Winter Wheat, the fungal disease, Take All, increases up to year 4, and then declines, and the yield rises again. There have been numerous studies of continous barley and wheat, Rothamstead institute in the UK has well over 100 years of continuous whaet at Broadbalk.

First year wheat is generally a higher grade crop, and yields are higher. On light land, 2nd yr wheat is often not a particularly attractive proposition

Grass species, such as Ryegrass pick up viruses and yields decline after about 3 years, but again stabilise, but with more weed grasses and the sward statrs to resemble permanent pasture.

Weed control often precludes continuous cropping. Black grass was controlled by IPU herbicides, but theses have been banned, so rotation with spring crops has started again, and sttempts are made to germinate the very small, long lived seed in the preceding autumn.

More specialist crops like Oil Seed Rape suffer from fungal infections like Alternaria if grown in a second year.
