KEY STUDY ON VEGETABLE PRODUCTION IN THE DISTRICT OF GIA LAM, HA NOI CITY, VIETNAM
In this paper we analyse the impact of the main conventional inputs, namely fertiliser, labour, seed and pesticide and the unconventional inputs such as farmer’s cultivation experiences and the seasonality on cabbage and kohlrabi yield.
A farmer household survey had been conducted to gather data for the analysis. 160 farm households in five villages, Van Duc, Thach Ban, Phu Dong, Dang Xa and Le chi, of the Gia Lam District of Hanoi City have been interviewed using prepared questionnaire.
The data collected included household’s characteristics, properties, vegetable production and marketing and farmer’s knowledge on vegetable cultivation.
The survey has been carried out from December 1997 to January 1998.
The mean test method had been used to compare the input used by farmer groups with different knowledge on vegetable cultivation and to compare the input used for the "ecological or clean vegetable production technology". Furthermore explorative statistical methods have been used to identify main factors determining the success of production.
