Answer:

The crop yield improvement is basically done for the following factors:

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?

Answer:

Plant more trees.

ii) Reduce excess irrigation that can cause loss of fertility and soil.

iii) Use organic manure and fertilizers that should protect crop health but protect them for infestation.
