Choice of Tillage Technologies and Impact on Paddy Yield and Food Security in Kilombero Valley, Tanzania
MetadataShow full item record
This paper analyses choice of alternative tillage technology options and their impact on paddy yield and food security in Kilombero valley of Morogoro Region, Tanzania. The results show that the choice of any tillage technology option combining hand hoe with animal traction and/or tractor is influenced by characteristics of household head (sex, age and education), access to extension, dependency ratio, land size and livestock assets. As hypothesized the three improved tillage technology options above the hand hoe enhance paddy yield and improve household food security. Factors other than tillage technology options that influence paddy yield and food security are characteristics of household head(sex, age and education), access to extension, use of fertilizer and herbicides, dependency ratio, farm size and livestock assets. The study recommends promotion of tillage technology options involving use of animal traction and yield enhancing inputs.
