The average rate of output growth since the 1950s has been more than 2.5 percent per year and was greater than 3 percent during the 1980s, compared with less than 1 percent per annum during the period from 1900 to 1950. Most of the growth in aggregate crop output was the result of an increase in yields, rather than an increase in the area under crops. The yield performance of crops has varied widely (see table 30, Appendix).
The national growth rates mask variability in the performance of different states, but in the regions with the greatest increases three categories are discernible. The first category includes states or areas that have an exceptionally high agricultural growth rate--Punjab, Haryana, and western Uttar Pradesh. The second is states or areas that have high growth rates, but not as high as the first category--Andhra Pradesh, Maharashtra, and Jammu and Kashmir. A third category has a lesser growth rate and includes Bihar, Gujarat, Karnataka, Orissa, Rajasthan, Tamil Nadu, eastern Uttar Pradesh, and West Bengal. These eight states, however, comprise 55 percent of the total food-grains area (see fig. 13).
Some observers believe that the increase in productivity has been an important factor explaining the satisfactory growth of food-grain production since the mid-1960s. However, the gains in productivity remain confined to select areas. Between FY 1960 and FY 1980, yields increased by 125.6 percent in North India (Punjab, Haryana, and western Uttar Pradesh). The increase in the other regions was much less: central India, 36 percent; eastern, 22.7 percent; southern, 58.3 percent; and western India, 31.6 percent. The national average was nearly 40.9 percent. Part of this disparity can be explained by the fact that during this period Punjab and Haryana were way ahead of other states in terms of irrigated area, intensity of irrigation, and intensity of cropping. Availability of irrigation is one of the crucial factors governing regional variations.
As a result of a good monsoon during FY 1990, food grain production reached 176 million tons, 3 percent more than in FY 1989. The production of rice and wheat was 74.6 million and 54.5 million tons, respectively. Among the commercial crops, sugarcane and oilseeds reached production levels of 240.3 million tons and 21.8 million tons, respectively. The increased production in FY 1990 was mainly the result of continuing increases in yields for all the main crops--rice, wheat, pulses, and oilseeds. In the case of oilseeds and sugarcane, higher production was also the result of the increased number of hectares planted (see table 31, Appendix).
The growth in food-grain production did not occur in a linear trend, but as a series of spurts depending mostly on the weather, input availability, and price policy. Aggregate growth was composed of an even split between area expansion and yield growth before FY 1964. Since FY 1967, the contribution of growth in yields has become dominant and attests to the vigor with which agriculture has responded to the opportunities opened up by new seed, water, and fertilizer technology.
Food grains include rice, wheat, corn (maize), coarse grains (sorghum and millet), and pulses (beans, dried peas, and lentils). In FY 1990, approximately 127.5 million hectares were sown with food grains, about 75 percent of the total planted area. The total number of hectares increased by 31 percent over the forty-year period from FY 1950 to FY 1990. Most of this increase occurred in the 1950s; there was almost no change in the sown number of hectares through the 1980s. Around 33 percent of cropland was given over to rice, about 29 percent to coarse grains, and the rest evenly divided between wheat and pulses.
Rice, India's preeminent crop, is the staple food of the people of the eastern and southern parts of the country. Production increased from 53.6 million tons in FY 1980 to 74.6 million tons in FY 1990, a 39 percent increase over the decade. By FY 1992, rice production had reached 111 million tons, second in the world only to China with its 182 million tons. Since 1950 the increase has been more than 350 percent. Most of this increase was the result of an increase in yields; the number of hectares increased only 40 percent during this period. Yields increased from 1,336 kilograms per hectare in FY 1980 to 1,751 kilograms per hectare in FY 1990. The per-hectare yield increased more than 262 percent between 1950 and 1992.
Wheat production showed an 843 percent increase, from nearly 6.5 million tons in FY 1950 to 54.5 million tons in FY 1990 to 56.7 million tons in FY 1992. Most of this greater production was the result of an increase in yields that went from 663 kilograms per hectare in FY 1950 to 2,274 kilograms in FY 1990. Along with the excellent performance in yields, improved wheat production resulted from an increase in the area planted from nearly 9.8 million hectares in FY 1950 to 24.0 million hectares in FY 1990.
Sorghum and millet, the principal coarse grains, are dryland crops most frequently grown as staples in central and western India. Corn and barley are staple foods grown mainly near and in the Himalayan region. As the result of increased yields, the production of coarse grains has doubled since 1950; there was hardly any change in the area sown for these grains. The production of pulses did not fare well, increasing by only 68 percent over the four decades. Land devoted to pulses increased by 28 percent, and yields were up by 30 percent. Pulses are an important source of protein in the vegetarian diet; the small improvement in production along with the increase in population meant a reduced availability of pulses per capita.
Before the Green Revolution, coarse grains showed satisfactory rates of growth but afterward lost cultivated areas to wheat and rice, and their growth declined. The area sown with coarse grains increased from FY 1950 to FY 1970 by roughly 20 percent but declined subsequently up to the early 1990s. In FY 1990 the area sown was 3 percent less than in FY 1950 and 20 percent less than in FY 1970. The area sown with two coarse grains, jowar (barley) and bajra (millet), increased from FY 1950 to FY 1970 and then declined during the 1970s and the 1980s. The area sown with jowar increased from 15.6 million hectares in FY 1950 to 17.4 million hectares in FY 1970 and then decreased to 14.5 million hectares in FY 1990. The area sown with bajra increased from 9.0 million hectares in FY 1950 to 12.9 million hectares in FY 1970 and stood at 10.4 million hectares in FY 1990. A similar pattern existed for other coarse grains. Overall, India's coarse-grain production increased from 15.4 million tons in 1950 to 29 million tons in 1980 to 33.1 million tons in 1990 and 33.7 million tons in 1993.
