Answer 2

Answer:

1.Agricultural implements are the machinery which are used on a farm to help with farming or to improve farming .

2.Plant hybridization. Plant hybridization is the process of crossbreeding between genetically dissimilar parents to produce a hybrid. It frequently results in polyploid offspring.

Explanation:

3.The breeding, rearing, and transplantation of fish by artificial means is called pisciculture, in other words, fish farming. It is the principal form of aquaculture, while other methods may fall under mariculture. It involves raising fish commercially in tanks or enclosures, usually for food.

4.It is very important to sow seeds at the correct distance from each other because plants need some space to grow up and to stretch their branches and they will get sufficient amount of sunlight and nutrients and their will be no competition for food and nutrients.

5.The following precautions should be taken while sowing seeds: (i) Seeds should be grown at proper depth. (ii) They should be sown at a proper distance apart from each other. (iii) Seed used for sowing should be clean, healthy and free from any disease or infection.The following precautions should be taken while sowing seeds: (i) Seeds should be grown at proper depth.

6.Winnowing is used to separate heavier and lighter components of a mixture by wind or by blowing air. This process is done by farmers to separate lighter husk particles from heavier seeds of grain.

7.Pesticides are poisons and, unfortunately, they can harm more than just the “pests” at which they are targeted. They are toxic, and exposure to pesticides can cause a number of health effects. They are linked to a range of serious illnesses and diseases from respiratory problems to cancer.Hey mate anyone delete my answer plz mark again me as barin list
