Types Of Agriculture

Traditional Agriculture Modern Agriculture

Importance of Modern Agriculture

• Increase in crop yields.• Diseased resistant varieties is developed.• Increasing food constituents in new varieties. • Use of pesticides and fertilizers.• The construction of large irrigation systems. • With the help of other branches of science agriculture is

well developed. - Biotechnology. - Tissue culture. - Genetic engineering. - Hybridization. - Green Revolution. Etc

Biotechnology

• Def- “The commercial application of living organisms or their products, which involves the deliberate manipulation of their DNA molecules"

Advantages- Identifying Organisms. Identifying Genes.

Diagnosing Diseases ,Genetic Disorders.

Plant tissue culture techniques are carry out under aseptic conditions.

Plant tissue culture is widely used to produce clones of a plant in a method known as micro propagation.

Application- Micro propagation is widely used in forestry and in floriculture.

-Large-scale growth of plant cells in liquid culture.

-Regeneration of transgenic plants.

Tissue Culture

Genetic Engineering Plant transformation Genetic engineering of plants is much easier than that

of animals. There are several reasons for this: (1) There is a natural transformation system for plants ,. (2) Plant tissue can dedifferentiate . (3) Plant transformation and regeneration are relatively

easy for a variety of plants.

Hybridization

• Hybridization refers to the union of the male and the female gamete to produce a zygote. In plant science, hybridization also refers to the crossing or mating of two plants.

• Combination breeding:• Hybrid varieties

Green revolution• Burlaug, a 1970 Nobel Laureate, was honored for his work

in the 'Green Revolution’. • Father of the Green Revolution"• The crops developed during the Green Revolution were high

yield varieties.• Produce an increased amount of grain per acre planted.• These technologies included modern irrigation projects,

synthetic nitrogen fertilizer and improved crop varieties .• Developed through the conventional, science-based methods available at the time.
