Abstract
The study examined the performance of rice production in Haryana and India during 47 years period, 1966/1967 to 2012/2013, consisting of five sub-periods i.e. P-I (1966/1967 to 1975/1976), P-II (1976/1977 to 1985/1986), P-III (1986/1987 to 1995/1996), P-IV (1996/1997 to 2005/2006) and P-V (2006/2007 to 2012/2013). Quantitative analysis is used to perform linear and exponential functions estimation using exclusively secondary data. The study reveals positive trends in area, production and yield of rice for both Haryana and India. The production of rice at the state level and at country level increased mainly due to increase in area. Similar results are obtained on triennium bases. Area, production and yield of rice crop have shown positive growth rates in Haryana during entire study period and five sub-periods, except for the yield in P-V. The overall trend in production of rice crop for India was found to be similar to that of Haryana; yield has shown positive growth rates during the entire study period and five sub-periods while negative growth rates were observed in area under the rice crop during P- IV and P-V.
