What is the first step in crop production?
- A Harvesting of the crop
- B Irrigation
- C Weeding
- D Preparation of soil
Correct answer: Preparation of soil
Preparation of soil is the first step in crop production. It involves ploughing and loosening the soil to improve aeration and facilitate root growth.
Which farm implement is drawn across a field to cut and turn over the topsoil before sowing?
- A Plough
- B Hoe
- C Sickle
- D Sprayer
Correct answer: Plough
A plough is used to turn and loosen the soil before sowing seeds. This helps in better aeration and nutrient mixing in the soil.
What is the process of placing seeds in the soil called?
- A Hoeing
- B Irrigation
- C Threshing
- D Sowing
Correct answer: Sowing
Sowing is the process of planting seeds into prepared soil. Proper sowing ensures adequate spacing and healthy plant growth.
Which machine sows grain at a uniform depth and spacing across a field?
- A Seed drill
- B Tractor
- C Harvester
- D Cultivator
Correct answer: Seed drill
A seed drill places seeds at uniform depth and spacing in the soil. This improves germination and crop productivity.
What are substances added to soil to enrich it with plant nutrients called?
- A Pesticides
- B Herbicides
- C Insecticides
- D Fertilizers
Correct answer: Fertilizers
Fertilizers supply essential nutrients such as nitrogen, phosphorus, and potassium. They help increase soil fertility and crop yield.
Which natural fertilizer is prepared from plant and animal waste?
- A Urea
- B Ammonium nitrate
- C Superphosphate
- D Compost
Correct answer: Compost
Compost is an organic fertilizer made by decomposing plant and animal waste. It enriches soil with nutrients and improves soil structure.
What is the supply of water to crops at regular intervals called?
- A Sowing
- B Harvesting
- C Irrigation
- D Ploughing
Correct answer: Irrigation
Irrigation is the artificial supply of water to crops. It ensures plants receive sufficient moisture for growth, especially in dry conditions.
Which irrigation method delivers water directly to the roots of plants?
- A Flood irrigation
- B Sprinkler irrigation
- C Drip irrigation
- D Canal irrigation
Correct answer: Drip irrigation
Drip irrigation delivers water directly to the base of plants through pipes and emitters. This method conserves water and reduces evaporation loss.
What are unwanted plants growing with crops called?
- A Herbs
- B Shrubs
- C Weeds
- D Crops
Correct answer: Weeds
Weeds are unwanted plants that grow along with crops. They compete for nutrients, water, and sunlight, reducing crop productivity.
What is the process of removing weeds from crop fields called?
- A Sowing
- B Harvesting
- C Weeding
- D Threshing
Correct answer: Weeding
Weeding is the removal of unwanted plants from crop fields. It helps ensure crops receive adequate nutrients and space to grow.
Which chemicals are used to kill weeds?
- A Herbicides
- B Fertilizers
- C Insecticides
- D Fungicides
Correct answer: Herbicides
Herbicides are chemicals designed to control or kill weeds. They help protect crops from competition for resources.
What is the cutting and gathering of mature crops called?
- A Harvesting
- B Irrigation
- C Sowing
- D Ploughing
Correct answer: Harvesting
Harvesting is the process of cutting and collecting mature crops from the field. It marks the final stage of crop production.
Which tool is traditionally used to harvest crops?
- A Sickle
- B Hoe
- C Plough
- D Seed drill
Correct answer: Sickle
A sickle is a curved hand tool used to cut mature crops during harvesting. It has been used in agriculture for centuries.
What is the process of separating grains from harvested crops called?
- A Threshing
- B Ploughing
- C Sowing
- D Irrigation
Correct answer: Threshing
Threshing separates the edible grains from the stalks and husks. This process can be done manually or using machines.
Which machine cuts mature crops and separates the grain in a single operation?
- A Combine harvester
- B Cultivator
- C Seed drill
- D Mechanical winnower
Correct answer: Combine harvester
A combine harvester combines the tasks of harvesting, threshing, and cleaning grain. It greatly increases agricultural efficiency.
Which crops are grown during the rainy season in India?
- A Rabi crops
- B Kharif crops
- C Cash crops
- D Fodder crops
Correct answer: Kharif crops
Kharif crops are sown during the monsoon season and harvested in autumn. Examples include rice, maize, and cotton.
Which crops are grown during the winter season in India?
- A Kharif crops
- B Rabi crops
- C Plantation crops
- D Cash crops
Correct answer: Rabi crops
Rabi crops are sown in winter and harvested in spring. Examples include wheat, barley, and mustard.
Which nutrient is essential for leaf growth in plants?
- A Nitrogen
- B Potassium
- C Calcium
- D Magnesium
Correct answer: Nitrogen
Nitrogen promotes healthy leaf and stem growth in plants. It is one of the key nutrients supplied through fertilizers.
What is the practice of keeping harvested grains safe from moisture and pests called?
- A Threshing
- B Storage
- C Weeding
- D Cultivation
Correct answer: Storage
Storage involves keeping harvested grains in conditions that prevent moisture, pests, and spoilage. Proper storage preserves food quality and prevents losses.
Which structure is commonly used for storing large quantities of grains?
- A Granaries
- B Canals
- C Greenhouses
- D Nurseries
Correct answer: Granaries
Granaries are storage structures designed to keep grains safe from pests and moisture. They are commonly used in agricultural systems worldwide.
