India ranks first in onion acreage in the world with over 15 million tons production. Maharashtra is the largest producer of onion producing about 33 per cent of the total production in the country. The area under onion has also increased substantially due to creation of various infrastructure facilities like onion storage and irrigation facilities. Therefore, the per cent changes in area, production and productivity of onion and compound growth rates were worked out. The present study used the data on area, production and productivity of onion for the period from 2007-08 to 2012-13. The area under onion in Maharashtra has increased by 44.69 per cent over the base year and it has increased at the rate of 6.42 per cent. The area under onion has significantly increased in Western Maharashtra region while it has significantly declined in Konkan region. Nasik and Pune divisions ranked the first in acreages under onion. The production of onion in Maharashtra has increased by 80.06 per cent and it has increased at the rate of 8.67 per cent. The production of onion in Western Maharashtra and Marathwada regions has increased drastically and in Konkan region, it has declined. The production of onion increased in Latur, Nasik, Amravati and Pune divisions and decreased in Thane and Nagpur divisions. The productivity of onion has increased from 13.27 to 16.51 tons/ha. and it has increased at the rate of 1.63 per cent during a period of last six years. The productivity of onion has increased in Western Maharashtra and Vidarbha regions and declined in Konkan and Marathwada regions, respectively. Nasik division ranked the first in productivity of onion. The study suggests that improvement in onion productivity as production is mainly influenced by acreage allocation in Maharashtra and it is not feasible without reducing the acreage under other important high value crops. The instability in production of onion was mainly due to area instability and partly due to yield. Volatility in the market price results in area instability. This may be reduced by providing timely market information prices, upgrading information, storage facility, and extending the weather based crop insurance to the farmers.
