Information About

Multiple Cropping




Multiple cropping is found in many agricultural traditions. In the Garhwal Himalaya of India , a practice called ''baranaja'' involves sowing 12 or more crops on the same plot, including various types of Bean s, Gram s, and Millet s, and harvesting them at different times.

In the cultivation of Rice , multiple cropping requires effective Irrigation , especially in areas with a Dry Season . Rain that falls during the Wet Season permits the cultivation of rice during that period, but during the other half of the year, water cannot be channeled into the rice fields without an irrigation system. Bunnett, p. 104. The Green Revolution in Asia led to the development of High-yield Varieties of rice, which required a substantially shorter growing season of 100 days, as opposed to traditional varieties, which needed 150 to 180 days. Due to this, multiple cropping became more prevalent in Asian countries. Bunnett, p. 107.

One kind of multiple cropping is Intercropping , where an additional crop is planted in the spaces available between the main crop. Bunnett, p. 123.
