In the hydroponics, foliar application of K, Mg and Zn increased
fruit number and yield of plants, but B and Cu decreased them
compared to control treatments. Castro et al. (2006) found that
irrigation with fish effluent enhanced tomato fruit number and
productivity in the first three analyzed harvest periods. However,
the increase in fruit number in treatments that received fish effluent
resulted in lower mean fruit weight. They found that even
with reduction on fruit mean weight, the increase in fruit num
