What are the advantages of using high yielding varieties of crops?
Some of the advantages are mentioned below: Higher and improved yield of crops. Most of the high yield crops are dwarf and hence, their plants are stronger and can withstand strong winds. The high yield crops give better response to fertilizers and thus, their production rate increases substantially.
What are the disadvantages of HYV seeds?
1. Biggest disadvantage associated with HYV seeds is bigger requirement of water and also chemical fertilisers and pesticides to produce best results. 2. Higher yields are possible only from combination of HYV seeds irrigation chemical fertilisers pesticides etc.
What are the advantages of varieties?
You are here
| Variety type | Advantages |
|---|---|
| Line | Breeding and multiplication are relatively easy |
| Population | Heterosis is exploited More stable, low genetic vulnerability |
| Hybrid | Optimum exploitation of heterosis Built-in penalty for reproduction and seed multiplication in farmers field Product uniform in maturity, quality |
What are high yield crop varieties?
The major high-yielding crops, in terms of land devoted to their culture and the total amount of produce, are wheat, corn, soybeans, rice, potatoes, and cotton. Each of these crops originated from a low-yielding native plant that was gradually converted into one of the highest-yielding plants in the world.
What is the benefit of high yield crops quizlet?
The seeds of high-yielding crops were larger, able to photosynthesize more efficiently, and able to grow even in places with limited sunlight. In addition, high-yielding crops meant that large varieties of crops were no longer necessary.
What are advantages and disadvantages of irrigation?
Advantages include low costs and minimal labor. A hose and a garden hoe are all it takes to have functioning furrows between vegetable rows. Water stays in the root zone, and foliage stays dry. Drawbacks to surface irrigation include potential overwatering and wasteful runoff.
What are advantages and disadvantages of HYV seeds?
Advantages and disadvantages of HYV seeds
| Advantages | Disadvantages |
|---|---|
| HYV crops are shorter so more able to withstand high winds and heavy rain | HYV crops require a more reliable source of water – irrigation increases costs. |
What are the disadvantages of plant breeding?
List of Disadvantages of Selective Breeding
- It can lead to loss of species variety.
- It does not have control over genetic mutations.
- It brings about discomfort to animals.
- It can create offspring with different traits.
- It could create a genetic depression.
- It poses some environmental risks.
How are high yielding varieties of crops obtained?
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.
How are high yield variety of crops obtained?
What is a disadvantage of industrial farming?
1. It increases the risk of animal cruelty. Factory farms keep animals in tight, confined areas where they don’t have the space to roam free and do what animals naturally do. In some cases, animals are kept in cages where they can’t move around at all.
Which of these are disadvantages of modern industrialized agriculture?
Drawbacks of industrialized Agriculture: -They have several environmental harms on the Earth. Industrialized Agriculture: Uses heavy equipment and large amounts of financial capital, fossil fuels, water, commercial inorganic fertilizers, and pesticides to produce single crops.
