What is HYV seed?
HYV seeds means high yielding varieties of seeds. HYV seeds produce much greater amounts of grain on a single plant. As a result, the same piece of land can produce far larger quantities of foodgrains than was possible earlier.
What is HYV seed Class 9?
HYV seeds stand for high-yielding seed varieties. HYV seeds generate more grain. High-yielding cultivars are created at research labs.
Who developed HYV seeds?
MS Swaminathan, known as the ‘Father of Green Revolution’ was born on August 7, 1925. Swaminathan developed high-yielding varieties (HYV) of wheat and later, promoted sustainable development which he called, the ‘evergreen revolution’.
What is called HYV?
High-yielding varieties (HYVs) of agricultural crops are usually characterized by a combination of the following traits in contrast to the conventional varieties: Higher crop yield per area (hectare) Dwarfness. Improved response to fertilizers. High reliance on irrigation and fertilizers – see intensive farming.
What is HYV give example?
These are referred to as high-quality crops. Such quality seeds are produced by crossing high-yielding crops having superior seed-producing capability. Crops that are resistant to drought and salt are produced in the same way. Examples are wheat and maize.
Where are HYV seeds developed?
High yielding varieties of seeds are developed in research institutes. High Yield Variety (HYV) seeds were developed by scientists to improve food supplies and reduce famine in developing countries. Hence, correct option is C.
What are features of HYV seed?
High Yielding Variety Seeds (HYV seeds) are seeds are of better quality than normal quality seeds. The produce from these seeds is a bit more compared to the normal ones. These seeds are a better option of seeds in order to obtain a healthy and surplus crop.
What is the role of HYV seeds in Green Revolution?
The high yielding variety of seeds played an important role in the Green Revolution of India. The high yielding seeds are generally flood and drought resistant and give better quality yielding. In the Kharif season of 1966, the high yielding programme was launched in selected areas having assured rainfall.
What are HYV seeds write its merits and limitations Class 9?
Answer: High Yielding Variety Seeds (HYV) has shorter life cycle and thereby enables the farmers to go for multiple cropping. Disadvantage or limit: The major disadvantage associated with HYV seeds is bigger requirement of irrigation facility, chemical fertilizers and pesticides to produce best quality yield.
What is HYV wheat?
High Yielding Variety Seeds (HYV seeds) are seeds that are of better quality than normal quality seeds. The produce from these seeds is a bit more compared to the normal ones. These seeds are a better option of seeds in order to obtain a healthy and surplus crop.
Who is called Father of Green Revolution?
Norman Borlaug, the American plant breeder, humanitarian and Nobel laureate known as “the father of the Green Revolution”.
What are HYV seeds Class 11?
Answer: High Yielding Variety (HYV) seeds are seeds, which produce large quantities of crops especially wheat and rice. The use of these seeds requires regular supply of water and optimum use of fertilizer and pesticide in correct proportions.
Are HYV seeds good?
These seeds have good immune system to fight with insects and other diseases. High Yielding Variety Seeds (HYV seeds) are seeds are of better quality than normal quality seeds. The produce from these seeds is a bit more compared to the normal ones.
What are HYV seeds Class 12 economics?
High yielding varieties (HYV) of seeds are those seeds which produce huge quantities of crops particularly wheat and rice. Regular supply of water, maximum use of fertilisers and use of pesticides in an accurate proportion is needed in to use these seeds.
When was HYV seeds introduced in India?
The Green Revolution started in 1965 with the first introduction of High Yielding Variety (HYV) seeds in Indian agriculture. This was coupled with better and efficient irrigation and the correct use of fertilizers to boost the crop.
How are high yielding varieties produced?
The highest yields are achieved in areas of well-managed irrigation and with adequate amounts of chemical fertilizers. At first the new varieties were highly susceptible to disease, and pesticides were necessary to obtain the high yield potential, but later varieties have been bred with a greater resistance to pests.
Do HYV seeds need more water?
The HYV crops require special irrigation facilities. They require more water as compared to normal crops. The increased water requirement for HYV seeds decreases the water table levels. Also, they require more fertilizers to grow healthy.
What are the major advantages of using HYV seeds?
High yielding variety (HYV) crops are shorter. So, they are able to withstand high winds and heavy rain. HYV crops also help in growing more foodgrains in a small piece of land, which increases farmers’ profits.
Are HYV seeds genetically modified?
In 1954, Borlaug, with funding from the Ford and Rockefeller Foundations, developed a genetically modified high yielding variety (HYV) of wheat seeds. These seeds went to the Philippines, India and Mexico, where they were able to increase their harvest from previous years significantly.
What is high yielding plants?
High-yield crops are those that produce the most food per square foot of garden. There are plenty of great books on growing more food with less space, including the recently released book, High-Yield Vegetable Gardening by Colin McCrate and Brad Halm.
