Legend:
YNFBV: When no/few; YNFBV: yields when very few or no bees visit my crop flowers (bad yield).
YHBV: When I receive high bee-visits to crops; YHBV: yields if bees came with high visitation frequency to flowers of my crop.
A: (Fruit/seed set in %) = [(mean YHBV − mean YNFBV)/mean YHBV]  *  100.
B: (Fruit/seed set in %); this is data obtained after conducting pollination experiments.
