Correct Answer: B. Fertilizers are chemically produced substances rich in specific nutrients.

Correct Answer: D. While fertilizers can boost yield, their overuse can harm soil fertility and contaminate water sources.

Correct Answer: A. Crop rotation involves growing different crops in a sequence to maintain soil fertility and reduce pest and disease pressure.

Correct Answer: A. Rhizobium bacteria form a symbiotic relationship with leguminous plants, converting atmospheric nitrogen into a usable form for plants.

Correct Answer: C. Fertilizers are man-made and do not provide humus, but they are rich in specific plant nutrients.

Correct Answer: B. Irrigation is the artificial application of water to crops to support their growth.

Correct Answer: D. Water plays multiple crucial roles in plant growth and development, including germination, nutrient transport, and protection.

Correct Answer: A. Higher temperatures and increased evaporation in summer necessitate more frequent irrigation.

Correct Answer: D. Rainfall is a natural source of water, while irrigation involves the artificial application of water.

Correct Answer: C. Moat is a traditional irrigation method involving a pulley system to lift water from a source.

Correct Answer: B. A chain pump uses a continuous chain with buckets to lift water from a source.

Correct Answer: D. Rahat employs a lever mechanism with buckets to lift water from a well or other source.

Correct Answer: A. A sprinkler system sprays water over a large area, making it efficient for uneven terrain and water scarcity.

Correct Answer: B. A drip system provides water slowly and precisely to the plant roots, minimizing wastage.

Correct Answer: C. Modern irrigation methods like drip and sprinkler systems are designed to conserve water by minimizing wastage.

Correct Answer: A. Weeds are unwanted plants that compete with crops for resources.

Correct Answer: D. Weeds negatively impact crop yield by competing for resources and hindering growth.

Correct Answer: B. Weeding is the process of removing weeds from the field.

Correct Answer: B. Weedicides are chemicals specifically designed to kill weeds.

Correct Answer: D. Irrigation is the process of supplying water to crops and does not directly control weeds.
