Weeding: The unwanted plants in the crops are called weeds. These weeds absorb the nutrients from the soil. So it is necessary to remove them. Weeds are either removed manually or by mechanical tools. The process of removal of weeds is called weeding. Some chemicals like 2, 4-D are also used to kill the weeds.

The process of watering the crops is called irrigation.

                  Two methods of irrigation are:

                 (i)   Sprinklers: Sprinklers work as fountains. Long perpendicular pipes have holes at regular distances. When water is supplied, it comes out of these holes and spray water in field. These holes have rotating nozzles which sprinkle water in all directions. They control wastage of water.                 (ii)   Drip System: This system is used to save water as it allows the water to flow drop by drop at the roots of the plants. It is the best technique for watering fruit plants, gardens and trees. Water is not wasted at all.

 Kharif Crops: The crops which are grown during the monsoon (rainy) season (June-September) are called kharif crops. For example, maize, millet (bajra) and cotton crops. Seeds of these crops are sown in the beginning of the monsoon season. After maturation, these crops are harvested at the end of the monsoon season (Oct.-Nov.).
