The objective of this paper is to systematically study the stability and
oscillation of the discrete delay annual plants model. In particular, we establish
some sufficient conditions for global stability of the unique positive fixed point and
establish an explicit sufficient condition for oscillation of the positive solutions about
the fixed point. Some illustrative examples and numerical simulations are included
to demonstrate the validity and applicability of the results.
