2. Introduction What is Green Revolution?? The Green Revolution was a period when the productivity of global agriculture increased drastically as a result of new advances. During this time period, new chemical fertilizers and pesticides were created. The chemical fertilizers made it possible to supply crops with extra nutrients and, therefore, increase yield. The newly developed pesticides controlled weeds, deterred or kill insects, and prevented diseases, which also resulted in higher productivity .

3. Definition The  Green Revolution  is a  term  referring to the reformation of agricultural practices resulting in dramatic increases in crop yields. Name : harsh kundu Class & section :XI-d Roll no. 21 School: The HeritageSchool

4. Significance The important economic  effects  of the  Green Revolution   is Increase in Agricultural Production: The first major direct  effect  of the  green revolution  has been the sharp increase in agricultural production. As a  result  of new agricultural strategy, food grains output increased substantially. Name : harsh kundu Class & section :XI-d Roll no. 21 School: The Heritage Schol

5. Historical Background The main development was higher-yielding varieties of  wheat , which were developed by many scientists, including American agronomist Dr.  Norman Borlaug , Indian geneticist  M. S. Swaminathan , and others. The  Indian Council of Agricultural Research  also claims credit for enabling the Green Revolution, in part by developing fungus resistant strains of wheat. The introduction of high-yielding varieties of seeds and the increased use of chemical  fertilizers  and  irrigation  led to the increase in production needed to make the country self-sufficient in food grains, thus improving  agriculture in India . The methods adopted included the use of  high-yielding varieties  (HYVs) of seeds with modern farming methods Due to the rise in use of chemical pesticides and fertilizers there were negative effects on the soil and the land such as land degradation.

6. Need / Features Land Reform – aimed to increase farm size, setting a limit on the amount of land the more wealthy could own and redistributing surplus land to those without. Irrigation was the need. Assured and regular supply of sufficient water to crops not only adds to production, it also assures stability in production. Indian rainfall being unreliable, irregular and seasonal. Farm mechanization: Mechanization saves a lot of human labour and quickens the farm operations, thereby adding to the farm efficiency and productivity.

7. Present Scenario Per hectare productivity of all crops e.g. wheat, rice, cotton, gram, maize and bajra has increased. It is due to better seeds. Chemical fertilizers, irrigation and mechanization of agriculture. Due to multiple cropping and excessive uses of chemical fertilizers, the demand for labour increased. At sowing and harvesting time, acute shortage of labour is experienced. So green revolution has generated employment. Name : harsh kundu Class & section :XI-d Roll no. 21 School: The Heritage School

12. Recent Development Green Revolution's start in India   In 1961, India was on the brink of mass famine.  Norman Borlaug  was invited to India by the adviser to the Indian minister of agriculture  C. Subramaniam . Despite bureaucratic hurdles imposed by India's grain monopolies, the  Ford Foundation  and Indian government collaborated to import wheat seed from the  International Maize and Wheat Improvement Center  (CIMMYT).  Punjab  was selected by the Indian government to be the first site to try the new crops because of its reliable water supply and a history of agricultural success. India began its own Green Revolution program of plant breeding, irrigation development, and financing of agrochemicals. India soon adopted  IR8  – a semi-dwarf  rice  variety developed by the  International Rice Research Institute  (IRRI) that could produce more grains of rice per plant when grown with certain fertilizers and irrigation.  In 1968, Indian agronomist  S.K. De Datta  published his findings that IR8 rice yielded about 5 tons per hectare with no fertilizer, and almost 10 tons per hectare under optimal conditions. This was 10 times the yield of traditional rice. IR8 was a success throughout Asia, and dubbed the "Miracle Rice". IR8 was also developed into  Semi-dwarf IR36 . In the 1960s, rice yields in India were about two tons per hectare; by the mid-1990s, they had risen to six tons per hectare. In the 1970s, rice cost about $550 a ton; in 2001, it cost under $200 a ton. [20]  India became one of the world's most successful rice producers, and is now a major rice exporter, shipping nearly 4.5 million tons in 2006.

13. Conclusion Green Revolution has done a lot of positive things, saving the lives of millions peoples and exponentially increasing the yield of food crops. But environmental degradation makes the Green Revolution an overall inefficient, short-term solution to the problem of food insecurity. So, more sustainable and environmental friendly system of cultivation needs to be practiced. The world needs green Revolution 2, which promises to feed a growing world population sustainably –without compromising the needs of future generations Name:Harsh Kundu class:& section :XI-D Roll no.21 School: The Heritage Schoo l
