how does the practise of mixed cropping reduce the risk of crop failure
Answers
Multiple cropping refers to growing more than one crop on the same field during the season. This technique makes effective use of inputs such as soil, water, fertiliser etc. Thus output per unit area increases with manifold returns to the growers.
With multiple cropping, incidence of crop failure owing to biotic agents is minimised. One crop may provide cover to the other against such agents through biological control. For example, canola is intercropped with wheat to shift aphid from wheat to canola, and okra intercropped with cotton diverts insect pests towards the latter.
practice of mixed cropping is best because of following reasons
if one crop destroy so other will can give profit to farmer.
soil will never lose its fertility
if some insects spoil one crop they can't harm others.
in less time more profit can be gain
