The correct answer is inter-cropping.Concept:Agriculture: It is the practice of growing crops and rearing animals.Crop: A crop is a plant that can be grown and harvested extensively for profit or subsistence.Explanation:Inter-cropping:Intercropping is defined as the agricultural practice of growing two or more crops on the same field at the same time in a specific pattern.Crops selected for intercropping normally have different abilities to use the resources available for growth.This leads to yield advantages and increased stability compared to a single crop in a low input system.Additional InformationSustainable farming: It is farming that meets the needs of existing and future generations, while also ensuring profitability, environmental health, and social and economic equity.It favours techniques that emulate nature€œto preserve soil fertility, prevent water pollution and protect biodiversity. Mixed cropping: It involves the growing of two or more species or cultivars of the same species simultaneously in the same field but not in a fixed pattern. It is done to reduce the risk of crop failure due to unfavourable conditions.Crop rotation:It is the successive cultivation of different crops in a specified order on the same fields.Usually, leguminous plants are grown in between cereals to replenish the nutrients in the soil.
