Explanations:In Jharkhand, the primitive form of cultivation is known as Kuruwa. This agricultural practice is deeply rooted in the traditions of the tribal communities in the region. Kuruwa is a form of shifting cultivation, which is also known as slash-and-burn agriculture. This method involves clearing a plot of land by cutting and burning the vegetation, and then using the cleared land for cultivation.
The process of Kuruwa typically begins with the selection of a plot of land, often in a forested area. The vegetation on the plot is cut down and allowed to dry. Once dry, the vegetation is burned, and the ash is left to enrich the soil. The cleared land is then used for planting crops such as millets, maize, and other food crops. The land is cultivated for a few years until the soil fertility decreases, at which point the farmers move to a new plot and repeat the process.
This method of cultivation is sustainable in the short term but can lead to environmental issues if not managed properly. Over time, the practice can lead to deforestation and soil degradation if the land is not given enough time to recover. However, in the context of Jharkhand, Kuruwa remains an important part of the agricultural heritage and is still practiced by many tribal communities.
It is important to distinguish Kuruwa from other forms of shifting cultivation that may be practiced in different regions. For example, Podu is a similar practice found in parts of Odisha and Andhra Pradesh, but it is not the term used in Jharkhand. Understanding the specific terminology and practices associated with different regions is crucial for correctly identifying the agricultural methods used in those areas.
