Question

Why is crop variety Improvement required ?write down six points.

Answer 1

(1) Higher yield: Crop variety improvement’s main goal is to increase the productivity of the crop. To develop high yielding variety.

(2) Quality product: To improve the quality of the food crops. The quality of crop depends on the type of crop. Considering the pulses and grains, they must have good baking quality. Oil crops should give a quality oil.

(3) Resistance: To develop resistance to both living and non-living factors. Biotic factors like insects, parasites, diseases, etc. and abiotic factors like hot, cold, drought, salinity, etc. affect the crop production. Resistant variety can withstand these factors and give a high yield.

(4) Maturity period: To shorten and to develop uniform maturity period. The short maturity period of crops helps farmers in multiple rounds of cultivation in less expenditure during a short period. Also, the uniform maturity of crops helps in easy harvesting. Thus, overall variety improvement makes the situation more profitable.

(5) Adaptation: To develop tolerance and make crops more adaptable to different conditions. The crops can be grown even in diverse conditions. For example, crops with tolerance to high salinity soil.

(6) Desirable agronomic characteristics: To develop desired agronomic characters in crops. This helps in a higher yield in less expenditure. For example, dwarfness in cereals helps to reduce the nutrient consumption without affecting the yield.
