Answers
Answer:
1(Biotic factors such as pests, insects and diseases reduce the crop production. A pest causes damage to our crops by feeding. Weeds also reduce crop productivity by competing with the main crop for nutrients and light. Similarly, abiotic factors such as temperature, wind, rain etc.

How do biotic and abiotic factor
Answer:
Here is Your answer..hope its helpful
Explanation:
1 ans:Both biotic and abiotic factors have their own effects on crop
Biotic factors
Biotic factors impact crop production in the subsequent ways :
1. Earthworms improve the texture of the soil.
2. Microbes such as nitrogen-fixing bacteria increase the fertility of the soil.
3. Insects serve as predators and keep the number of crops under control.
Abiotic factors
Abiotic factors impact crop production in the subsequent ways :
1. Sunlight aids in photosynthesis.
2. Water and minerals from the soil along with gases are the raw materials for the synthesis of food and energy.
3. Suitable temperature is required for the proper growth of the plant and various processes such as transpiration.
4. Rainfall is required for natural irrigation of plant.
2 ans:Desirable agronomic characteristics are different for different crops. Cereals should be dwarf but with large ears. Dwarfness makes their stem stronger. They can withstand lodging affect of strong winds. Nutrient requirement is also less. Large ears produce more grains. Legumes should have more pods which generally develop in relation to stem branching. Therefore, more branching and good foliage increase their productivity. Fodder crops meant for feeding cattle must have profuse branching, good foliage, juicy stems and large size.
