Question

what r the main effects of green revolution on crops?​

Answer 1

The Green Revolution, which was a period when the productivity of global agriculture increased drastically as a result of new advances, was a very important period in agricultural history. ... Although it had several benefits, the Green Revolution also had some negative effects on the environment and society

Answer 2

the main effects of green revolution on crops

i) Increase in Production and Productivity:

As a result of new agricultural strategy, food grains output substantially increased from 81.0 million tonnes in the Third Plan (annual average) to 203 million tonnes in the Ninth Plan (annual average) and further to 212. 0 million tonnes in 2003-04. HYVP was restricted to only five crops – wheat, rice jowar, bajra and maize. Therefore, non- food grains were excluded from the ambit of the new strategy.

Wheat has made rapid strides with its production increasing from 11.1 million tonnes (Third Five Year Plan) to 71.3 million tonnes in the Ninth Plan. The production of wheat touched a high level of 72.1 million tonnes in 2003-04, the overall contribution of wheat to total food grains has increased from 13 per cent in 1950 – 51 to 34 per cent in 2003-04. The average annual production of rice rose from 35. 1 million tonnes in the Third Plan to 87.3 million tonnes in the Ninth Plan. It stood at 87.0 million tonnes in 2003-04.

(ii) Scientific Cultivation:

A very important effect of Green Revolution is that traditional agricultural inputs and practices have given way to new and scientific practices. Instead of farm seeds, farmers are now using HYV seeds. Traditional fertilizers are replaced by chemical fertilizers. Consequently under HYV seeds increased sharply from 1.66 million hectares in 1966-67 (when green revolution came to India) to about 78.4 million hectares in 1998-99.

(iii) Change in Cropping Pattern:

Two changes are significant. First, the proportion of cereals in the food grains output has increased and the proportion of pulses has declined. Second, the proportion of wheat cereals has increased while that of coarse grains has declined.

(iv) Development of Industries:

Green revolution has benefited the industrial development. Many industries producing agriculture, machinery, chemical fertilizers, pesticides, insecticides etc., have come up to meet the growing demand for these commodities.
