Onion (Allium cepa) also known as bulb onion or common onion, is a vegetable crop that belongs to family Amaryllidaceae and the most widely cultivated species of genus Allium. Onion is an important horticultural commodity grown worldwide for their culinary purposes and medicinal values. Indian onions are famous for their pungency and are available round the year. One cup of chopped onion contains approximately 64 calories, 15gm of carbohydrate, 0 gm of fat, 0 gm of sugar, 2gm of protein and10 percent or more of the daily value for vitamin c, vit-B-6. For the present study the growth rate and instability in area production and yield were studied for the country as a whole. The data related to area, production and productivity of onion were collected for the period 1995-96 to 2018-19. To estimate the growth in area, production and yield compound growth rate were used. Cuddy-Della Valle Instability Index was used to estimate the instability in area, production, yield. The results revels that, compound growth rate of area, production and yield of Onion were statistically significant and positive. The highest instability was observed in production of onion followed by area and yield.
