<br/><br/> Study examines the effect for the vulnerability of food production of a very important element among the bio-chamical inputs, high yielding seed. Purpose is to examine how the diffusion of hybrid maize in the southern highlands of Tanzania in combination with related bio-chemical inputs through changes in the farming systems affects the vulnerability of food production.
