The price of vegetables in Kathmandu Valley has increased by over 100 percent in comparison to the last year due to the falling supply as production has been affected by the unexpected rainfall before and after Dashain festival.
The Kalimati Fruits and Vegetables Market Development Board said price of potato, onion, cauliflower, cabbage, radish, brinjal,ginger, garlic and others has been continuously rising since the last year.

The price of onion, for which we have to depend on India, has increased the most in the past one year as its price escalated even in India. Its wholesale price has increased astronomically from Rs 27.40 a year ago to Rs 112 on Wednesday. Its price was Rs102 last month and Rs 97 a week ago.

The wholesale price of ginger also rose by 231 percent from Rs43.80 a year ago to Rs 145. It was Rs 105 a month ago and had increased by Rs 50 to Rs 155 a week ago. The majority of internally produced ginger had been exported last week even as it was being sold at a high price in the domestic market. The price of both ginger and onion has skyrocketed as we have not been able to produce them domestically. The price of other vegetables has risen due to the fall in production owing to the rainfall. The price of many vegetables fluctuates according to season.

The price of tomato, however, has fallen by 23 percent from Rs 42 last year to Rs 32 on Wednesday. It was Rs 33 a month ago and had increased to Rs 45 a week ago.

Consumers write to chief secretary for control of inflation
The National Consumers Forum has written to Chief Secretary to control the unnatural price hike of vegetables in the market. President of the forum revealed the letter has been sent stating that the businessmen have artificially raised the price of essential goods during the festival season and ahead of the upcoming Constituent Assembly (CA) election. He said the price has increased by 20 to 30 percent.

The forum has urged chief secretary to take solid steps immediately and to bring those involved in black-marketing to the book stating that there has been unnatural hike in price of potato, onion, radish, cucumber, vegetable oil, mustard oil, sugar and fruits. The forum has concluded that the businessmen have artificially raised price capitalizing on the lack of monitoring during the festival season.
