Plough is a wooden agricultural implement consisting of ploughshare and ploughshaft used to prepare the soil. It helps in loosening and turning the soil. The seed drill is used for sowing seeds uniformly at proper distances and depths. NPK is used as an addition of fertilizer to the soil, and NPK stands for nitrogen, phosphorus, potassium. The Sprinkler system is a modern method of irrigation. In this method, water is sprayed all over the field, like rainfall. Weeding can be done by using a hand tool, khurpi. Weeding is the process of removing unwanted plants that are grown along with the crop. A combine harvester is a machine that is used for both harvesting and threshing. Silo is a tall tower or pit on a farm used to store grains (storage). Rabi crops are grown at the end of the monsoon season. Wheat is the main crop of rabi season. Organic manure is formed by the decomposition of plant and animal waste. It helps in increasing soil fertility. Kharif crops are also called monsoon crops. Paddy is the main crop of Kharif season. Urea is a chemical fertilizer used in agricultural activities to supply nitrogen to crop. Crop rotation helps in replenishing the soil with nutrients. Animal husbandry is the rearing of farm animals on a large scale for food and other needs. Column A Correct match 1. Soil preparation h. Plough 2. Sowing k. Seed drill 3. Addition of fertilisers a.
