Explanation
A soil plank is a tool used for breaking up pieces of soil. It is specifically designed to loosen and break apart compacted soil, making it easier for planting and gardening. The other options, such as soil leveller, harrow, and sowing, are not specifically used for breaking up soil.

Explanation
Threshing is the correct answer because it refers to the process of separating grains from the main crop plants. This is typically done by beating or shaking the plants to loosen the grains, which are then separated from the rest of the plant material. Winnowing is a related process that involves separating the grain from chaff or other debris using air currents. Harvesting refers to the overall process of gathering crops, which may include threshing. Tilling, on the other hand, is the process of preparing the soil for planting, not separating grains from plants.

Explanation
Harvesting refers to the process of cutting and gathering crop plants. It involves the removal of mature crops from the field, typically done when the crops have reached their maximum yield and are ready for collection. This process is essential in agriculture as it allows farmers to obtain the fruits, vegetables, or grains that they have cultivated. Harvesting can be done manually or with the help of machinery, depending on the scale of the operation and the type of crop being harvested.

Explanation
A farmer is a person who manages a farm. They are responsible for cultivating crops, raising livestock, and overseeing all operations related to the farm. Farmers play a crucial role in ensuring food production and are involved in various tasks such as planting, harvesting, and maintaining the farm's infrastructure. They possess knowledge and skills related to agriculture and are dedicated to the management and success of their farm.

Explanation
Weeding is the correct answer because it refers to the process of removing unwanted plants. Weeding involves the removal of weeds from an area where they are not desired, such as a garden or a field. This is done to prevent the unwanted plants from competing with desired plants for resources such as sunlight, water, and nutrients. Weeding is an important practice in agriculture and gardening to maintain the health and productivity of crops and plants.

Explanation
Winnowing is the correct answer because it refers to the process of separating grains from chaff and dust. This is done by throwing the mixture into the air and allowing the wind to blow away the lighter chaff and dust particles, while the heavier grains fall back down. Harvesting, threshing, and sowing are not the correct answers as they refer to different stages or processes in agriculture.

Explanation
Kharif crops are sown in the rainy season. These crops require a lot of water and are typically sown at the beginning of the monsoon season. Examples of Kharif crops include rice, maize, millet, and cotton. These crops are well-suited to the rainy season as they can withstand heavy rainfall and thrive in the wet conditions. Rabi crops, on the other hand, are sown in the winter season and require less water. Therefore, the correct answer is Kharif.

Explanation
Tilling is the process of loosening the soil by turning it over or breaking it up. This is usually done using a tool such as a plow or a tiller. Tilling helps to aerate the soil, improve its structure, and make it easier for plants to grow. It also helps to mix in organic matter and nutrients, making them more accessible to plants. Harvesting, spraying, and weeding are all different processes that are not related to loosening the soil.

Explanation
Irrigation refers to the process of supplying water to crops in order to help them grow and develop. It is an essential practice in agriculture as it ensures that plants receive the necessary amount of water for their proper growth and development. Irrigation can be done through various methods such as sprinklers, drip systems, or flood irrigation depending on the specific needs of the crops and the availability of water resources.

Explanation
Tenant farmers are individuals who rent or lease land from a landowner in order to cultivate crops or raise livestock. They do not own the land themselves but rather pay a rent or share of the profits to the landowner. This distinguishes them from other types of farmers such as nomadic farmers who move from place to place in search of fertile land or seasonal migrators who move with the changing seasons to engage in agricultural activities. Therefore, the correct answer is "Tenant".
