becomes necessary to increase the crop variety to produce disease-resistance offsprings of the crops. It also helps in providing better and superior varieties based on the quality and quantity of the yield.
Higher yield: You can achieve a higher yield of crops by developing HYV (high yielding variety) crops. This can be done by the process of hybridization and cross-breeding.
Better quality: There are different reasons for improving the quality of different crops, such as improvement of the baking quality in cereals like wheat. On the other hand, pulses need to have better protein quality.
Biotic and Abiotic Resistance: We should develop crops that are resistant to biotic stresses like insects and diseases and abiotic stresses like heat, salinity, and cold. This can significantly improve the crop production in the country.
Various Desirable Agronomic Traits: Higher production can be achieved by developing such varieties of crops that contain the desirable agronomic traits to sustain the various threats during the production process.
Better and Wider Adaptability of The Crops: By developing crops with better adaptability to changing climatic and nutritional conditions, we can stabilize the crop production, thus, leading to higher yields in crop each year.
Easier to Adapt to Changing Climatic Conditions: We must concentrate on producing the varieties that are easier to adapt to the new and changing climatic conditions easily. This is one great way to improve the crop yield.
How to Improve the Crop Yields?
There are three basic approaches that are adopted in our country to increase the yield from agricultural fields. They are:
Crop variety improvement
Crop production management
Nutrient management
Crop variety improvement
By this technique, what we mean is the combination of desirable characteristics from many crops into a single hybrid crop. The next step would be multiplying it. This method calls for the plant breeders to select the desirable characteristics and cross them so that the offspring has the best of both worlds! Isn’t it simply marvellous?
Why is There a Need for Higher Crop Yield?
With rising population and livestock, the demand for food and fodder has been increasing like never before.
Along with that, there is a rise in the standard of living and people have become more conscious about their health. This has led to an increase in the demand for good quality products.
It becomes necessary to increase the crop variety to produce disease-resistance offsprings of the crops.
It also helps in providing better and superior varieties based on the quality and quantity of the yield.
Crop Production Management
India is basically an agriculture-based country. Around 3/4th of the population in the country is dependent on agriculture for a living. Based on the size of the farms, different farmers have different amounts of money, information, and technology to develop the crops.
The more the inputs, the higher is the yield. Accordingly, there are three types of crop production management. These include ‘no cost’, ‘low cost’ and ‘high cost’ production practices.
Nutrient Management
This is an important part of improving the crop yield as plants do need inorganic elements for their growth. Many macro and micronutrients are important for the plants to build their structure and maintain their metabolism. There are sixteen types of nutrients that are required by the plants, which are subdivided into two categories:
Macronutrients: These are the essential elements that are required in relatively in large quantities by the plants. Examples include carbon, oxygen, hydrogen, nitrogen.
Micronutrients: These are necessary for the plants in small quantities. Examples include magnesium, iron, boron, zinc etc.
Higher yield: You can achieve a higher yield of crops by developing HYV (high yielding variety) crops. This can be done by the process of hybridization and cross-breeding.
Better quality: There are different reasons for improving the quality of different crops, such as improvement of the baking quality in cereals like wheat. On the other hand, pulses need to have better protein quality.

it is required to improve crop variety bcozz we know weather conditions soil quality and availability of water are the main factors on which crop yields depends. As weather conditions like drought and flood situation are unpredictable it is important to have varieties that can grow in adverse climatic conditions.
Two methods are :-
1.) High yield
2.) Improve Quality...
