Also the standards of picking, edible ways and functions of these varieties were briefed here to provide a technological support for orienting the vegetable production in Shanghai towards good quality, diversity and market.展开更多

Questionnaire, which was randomly distributed, was used for data collection from 270 direct beneficiaries of the project. Frequency, percentage and multiple regression were used for data analyses. For the beneficiaries, the results indicated a mean age of 48 years, 9 years of formal education, annual net farm income of N115, 681.48 and 2.8 times of monthly contact with Project Extension Officers. The mean adoption status of the project was 56.6%. The relationship between socio-economic characteristics of beneficiaries and adoption status gave an R2 of 0.668. Age, education, farming, experience, farm income and extension contact were significant determinants of adoption. The study recommends improvement in formal education, farm income, extension contact and inclusion of younger farmers as beneficiaries to enhance adoption status.展开更多
