is the planting of a plot of land with several varieties of the same crop.
It is a subordinate counterpart of
growing of two or more crops simultaneously on the same piece of land with a definite row pattern, which both serve their purposes.
1. Gives additional yield income/unit area than sole cropping.
2. Acts as an insurance against failure of crops in abnormal year.
3. Maintain the soil fertility as the nutrient uptake is made from both layers of soil.
4. Reduction in soil runoff and controls weeds.
5. Provide shade and support to the other crop.
6. Utilizes resources efficiently and their productivity is increased (Reddy and Redid, 1992).
7. Cash crops is higher profitable.
8. Avoid inter-crop competition and thus a higher number of crop plants are grown per unit area.
1. Yield decreases as the crops differ in their competitive abilities.
2. Management of different cultural practices seems to be difficult task.
3. Improved implements cannot be used efficiently.
4. Higher amount of fertilizer or irrigation water cannot be utilized properly as the component crops vary in their response of these resources.
5. Harvesting is difficult.
1. Insurance against total crop failure under aberrant weather conditions or pest epidemics.
2. Increase in total productivity per unit land area..
3. Judicious utilization of resources such as land labor and inputs
