Question

What are the advantages of multiple cropping

Answer 1

In most multiple cropping systems developed by smallholders, productivity in terms of harvestable products per unit area is higher than under sole cropping with the same level of management (Francis, 1986). Yield advantages can range from 20 to 60% and accrue due to reduction of pest incidence and more efficient use of nutrients, water and solar radiation.
Enhanced yields in diverse cropping systems may result from a variety of mechanisms such as more efficient use of resources (light, water, nutrients) or reduced pest damage. Intercropping, which breaks down the monoculture structure, can provide pest control benefits, weed control advantages, reduced wind erosion, and improved water infiltration
Crop diversification strategies must be complemented by regular applications of organic amendments (crop residues, animal manures and composts) to maintain or improve soil quality and productivity.
Agroecological approaches increased the stability of production as seen in lower coefficients of variance in crop yield with better soil and water management.

Answer 2

 Advantages of multiple cropping are:

(a) Efficient use of land: Land is not left idle at any time of the year and therefore more efficiently used in the process of production.

(b) Increase of production : It increases the production on a piece of land during the year.

(c) Increase in income : Multiple cropping increases the agricultural income of the country as well as for the farmers.
