  1. Modern Agriculture Presented By Shubhangi. L .Sabale. Pallavi .S. Nandanwar.

  2. Types Of Agriculture TraditionalAgriculture Modern Agriculture

  3. 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

  4. 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.

  5. Tissue Culture 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.

  6. 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.

  7. 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

  8. 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.
