Following are the advantages of mixed cropping:
It reduces the risk of crop failure due to environmental stress.
Pest infestation of crops is greatly reduced.
It increases soil fertility.
It increases the yield of both the crops due to complementary effect of each crop.
Following are the disadvantages of mixed cropping:
Spraying pesticides to individual crops is difficult.
Applying fertilizers to individual crops is very difficult.
Harvesting and threshing of crops separately are not possible.
Advantages of mixed farming
In mixed farming, all products are utilized.
Money is saved as there is reduced cost of feeding farm animals and reduced or no cost of fertiliser application.
If a crop does poorly in a season, the farmer can fall back on income from sales of meat, milk and eggs.
There’s a crop-livestock mutual relationship, both plants and animals help each other grow.
There is limited capacity in the sense that a farmer who grows maize and raises dairy cattle cannot grow as much maize as the farmer who grows only maize.
More resources are required in caring for your crops and raising your animals.
Farm animals may feed on crops before harvest stage, thus resulting in loss of yield and reduction in market value.
System that involves using a same piece of land for growing crops as well as rearing animals is defined as multiple farming. it includes agriculture practices such as dairy farming, bee keeping, poultry etc. some of the disadvantages of mixed farming are listed below:
decreased level of production as compared to monoculture.
growth rate and optimal harvest date differ.
inappropriate climatic condition.
animals can be hazardous if they are not properly enclosed or tethered.
needs higher level of management and trained labour which is always expensive.
makes controlling, monitoring and maintenance procedure more difficult.
competition among the farming agents for the resources.
one species may host the pathogens so diseases transmission becomes more easier.
In North Africa, there are mainly 4 types of farming system which is highland mixed , rainfed mixed, irrigated and dryland mixed farming system. The most common type of agriculture farming system in North Africa is highland mixed system which consist of two major subsystem and they can affect each other, it support 30% agriculture in North Africa in 2001.The first system is dominated by rainfed cereal and legume crop , tree crop ,vegatable crops, commonly it is comprise primarily of monocultures. At summer season ,it need to provide some supplementary irrigation in order to plant crops just like melons that are high water content and nutrient content fruits. Second system is mainly base on livestock (mostly is sleep) on grazing lands surrounding these cropped area. it is also a kind of transhumance system which means it requires to migrating between lowlands and uplands as the charge of season and resources. The advantage of highland mixed farming system is increasing the competition from subsidized imports of meat and dairy products which impoverish small local producers as it provide larger farming area for them. Also, it reduces the water erosion by use of terraces as reducing the slope in order to maintain the soil content for farming, therefore it prevents nutrient content flushed by water.
