Answer 2

Answer:

1) Nutrients and space

2) Ploughing

3)Inter cropping

4)Kharif - Paddy , soyabean

Rabi - Wheat , Gram

5)The unwanted plants which grow along with a cultivated crop are called weed. The type of weed vary from field to field , Crop to crop , Season to season for eg: Wild oat , grass ,Amaranthus , chenopodium etc , The process of removing weeds from a crop field is cc alled weeding

6)

• The Loose soil allows the roots of plants to breathe easily.
• The Loose soil helps in the growth of worms and microbes present in the soil who are friends of the farmer.
• The Loose soil allows the roots of pants penetrate freely and deeply into the soil so that plants are held more firmly to the ground.

7) The crops which are sown in the rainy season are called Kharif crops. The rainy season in India is generally from June to September. paddy maize , soyabean , Groundnut , etc are Kharif crops.

8). Sprinkler irrigation

This irrigation has an arrangement of vertical pipes with rotating nozzles on the top. It's more useful in the uneven and sandy land where sufficient water is not available.

Drip irrigation system

This irrigation has arrangement of vertical pipes or tubes with very small holes him them to water plants drop by drop just at the base of the root. It's is very efficient water is not wasted at all.

9) Fertilizers

• Chemical substances which are rich in a particular nutrient.
• Microbes are not needed
• These do not restore soil texture
• A Fertilizers are prepared In factories
• A Fertilizers does not provides any humus in the soil.

Manure

• It's an organic substances obtained from the decomposition of animals and plant wastes.
• Microbes like Bacteria and fungi are needed.
• They restore soil texture
• Manure can be prepared in the field
• Manure provides a lots of humus of the soil

10) Weeding

Weeding or weed control is the process of removing unwanted plants from crop fields. Here physical , chemical and biological methods are used to stop weeds from reaching a mature growth of when they could be harmful to domesticated plants and live stock. The most basic is Ploughing which the cuts the roots of annual weeds. weeding is essential weeds tend to compete with the crops for food , crops , water and light greatly reduce the crop yield.

Threasing

Threasing is the process of loosing in the edible part of grain from the straw to which it's attached. It's the step in grain preparation after reaping. Threasing does not remove the bran from the grain.

Preparation of soil

Preparation of the soil is the first step before growing of crop. It helps to turn the soil and loosen it to allow the roots of penetrate deep into it. The loosening of the soil helps in the growth of several soil microbes , earthworms etc; which enrich the soil with humus and the other essential nutrients.

Sowing

Sowing is the process of putting the seeds into the soil for growing crops. We need to use quality seeds for sowing. Sowing is done manually using mechanical equipment like seed drill. Seeds of few plants like rice are first grown ina separate area and then transplanted in the fields.

Affects on soil due to continuous plantation of crops in a field

Continuous plantation of crops in a field makes the poor in certain nutrients such as nitrogen , phosphorus, potassium, etc; When a farmer continuous to grow crops one after the other , then all nutrients available in the soil reduce and the crops decrease in automatically

• Speargrass
• Slugs
• Parasitism
• Leguminous crops
• Nitrogen
