Your query in incomplete, I assuming that you are asking for the advantages of intercropping. Please find the solution below:
Intercropping is a cropping pattern in which farmers grow two or more crops simultaneously in same field in a definite pattern. For example : soyabean and maize. Their nutrient requirement are different and they are grown in alternate rows. Soyabean brings nitrogen from air to soil, thus improves fertility of soil. Growing soyabean before maize reduces infestation of weed like striga in the maize field.Advantages of Intercropping pattern:
