摘要
Meeting the daily nutritional needs of ever grow population of Malawi is a daunting challenge given some recent setbacks in national maize production. Alternative crops like soybean with high protein contents should therefore be explored. This study determined the factors that are influencing adoption intensity of improved soybean varieties and technical efficiency of its production. Data that were collected from 300 farmers in Central Malawi were used. Tobit regression and Maximum Likelihood Estimation of production frontier were the methods of data analysis. The results show that average farm size is 1.75 ha with average of 0.21 ha devoted to soybean cultivation. Average planting of local and improved seeds were 27.78 kg per ha and 21.16 kg per ha, respectively. The traits that were most desired by farmers were high yield and early maturity. Adoption intensity significantly increased with soil conservation information and land endowments (p<0.10), while inefficiency significantly reduced with education and usage of improved maize varieties (p<0.05). No significant technical efficiency exists between local and improved soybean seeds growers (p>0.10). It is recommended that research on soybean should focus on high yielding and early maturing varieties, and promotion of extension contacts.
