是

2.1 技术简介

技术定义:

Multiple cropping is an agronomic practice of growing two or more crops on the same land simultaneously in a given growing season

2.2 技术的详细说明

说明:

Growing of different types of crops in the same field. The crops grown together are, however, harvested at different times. In the Konso case the farmers are used to growing of 10-15 types of crops on the same area. The purpose is to avoid risk (some crops are more resistant or escape the adverse conditions like drought, pest and disease) and to get variety of produce at a time. Annual crops are sown/planted every season. Binual and perenial crops are planted and managed according to their seasonal calendar in which the crops grown to provide better production. Low fertility status, unpredictable and erratic rainfall, pest and diseases are some of the constraints limiting productivity.
