The high level of homogeneity of fertiliser and pesticide application
practices within each cropping system resulted in relatively
homogeneous production costs per system; however, there were
diverse outcomes in terms of yield (as shown in Fig. 4 for the 43
cropping systems -year 2010) and therefore of gross and net income.
Net income per systemwas wide-ranging, with the Id system
being the least profitable and the most variable. Conditions during
the dry season are less favourable temperature-wise and more
uncertain and variable in terms of water management. Iw systems
showed higher homogeneity of results and a potential for the
highest yields and net income.
