Agronomy crops are classified into several categories based on their utilization, including cereal crops, oilseed crops, pulse crops, fiber crops, feed and forage crops, and spices and condiments. Cereal crops like rice, wheat and maize are staple foods, while oilseed crops such as mustard and sunflower are grown for their oil. Pulse crops including green gram and black gram are legumes rich in protein. Fiber crops, feed crops, and spices are also important for various uses. Agronomy studies the management of crop production and combines multiple sciences to understand plant and soil capabilities.
