Because the majority of crops (cereal crops) are wind pollinated.
In self pollinated crops, hybrid vigour is not just like the cross pollinated crop e.g maize.cross pollination in self pollinated crop produce low seed set and cost of hybrid seed increases.less cytoplasmic male sterility and fertility restorer gene in mostly self pollinated crop.

you'd get a uniform genetic composition for good or bad. you can get a uniform crop or you may get inbreeding problems
sesame is self or cross pollinated crop

Barley is predominantly self-pollinated, aided by the wind..
