Growth in Agricultural Resource USE: An Application of Exponential Growth Curve.
Agriculture is the means of livelihood for around two thirds of the work force of India. Agriculture is the production, processing, marketing and use of foods, fibers and bye prducts from plant crops and animals. It was the key development that led to the rise of human civilization with the husbandry of domesticated animals plants creating food surpluses that enabled the development of more densely populated and stratified societies. At the time of independence, the revenue from the agriculture sector was quite low compared to what it is today. The main reason for the increase in the revenue is the in crease in agricultural production that was brought about by the Green revolution, over the years, agriculture has emerged as one of the top priorities of the Central & state governments. In 2000, the government announced the first over “National Agriculture Policy”. The resources taken were consumption of fertilizers, consumption of electricity in agricultural sector, short term and long term credit, number of tractors, area under high yielding varieties, net irrigated and gross irrigated area and total cropped area. It was computed using the exponential trend equation i.e.: Y = abt Log Y = log a + t log b taking ^ b = (1+r) r = (b-1) x 100 Where Y = study variable; area, production, yield or Resource variables a = constant ^ b = regression coefficient t = time, t = 1 ……………n r = compound growth rate in percent To test the significance of the compound growth rates, t-test applied was t* = r/S.E( r) Where t* = calculated t-ratio, distributed with (n-2) degrees of freedom r = compound growth rate S.E. (r) = standard error of the compound growth rate, S.E. was calculated by fitting the following formula. 100 x b S.E. (r) = Σ (log y)2 (Σ log y)2 (log b )2 Σ ( t – t )2 Log 10e n (n-2) Σ (t – t )2 where the limit for Σ is, i = 1,2……n
