The effect of nitrogen fertilizer on sex expression and yield of summer squash was studied under field condition during spring and fall season. The most effective rate was 160 kg N/ha which lowered the position of first pistillate flowers and increased the number of pistillate flowers per plant. This nitrogen rate gave also a higher number of fruit and higher yield than other treatments tested during spring and fall seasons
