Answer:

Ans 1: Intercropping is a multiple cropping practice involving growing two or more crops in proximity. ... The most common goal of intercropping is to produce a greater yield on a GIVEN piece of land by making use of resources or ecological processes that would otherwise not be utilized by a single crop.

Ans 3: Agronomists describe the benefits to yield in rotated crops as "The Rotation Effect". There are many benefits of rotation systems. The factors related to the increase are broadly due to alleviation of the negative factors of monoculture cropping systems. Specifically, improved nutrition; pest, PATHOGEN, and weed stress reduction; and improved soil structure have been found in some cases to be correlated to beneficial rotation effects.

Other benefits of rotation cropping systems include production cost advantages. Overall financial risks are more widely distributed over more diverse production of crops and/or livestock. Less reliance is placed on purchased INPUTS and over time crops can maintain production goals with fewer inputs. This in tandem with greater short and long term yields makes rotation a powerful tool for improving agricultural systems

Ans 4: The importance of LEGUMINOUS plants is that these crops have nodules which are SYMBIOTIC nitrogen fixing bacteria. This is good for the soil because the bacteria fix atmosphere nitrogen into the soil which increases the natural level of soil nitrogen, this is vital for plant growth
