Abstract：A field experiment was carried out to study the effects of furrow irrigation quantity and nitro-gen application level at sowing date on reproductive allocation of cotton in the Yellow River delta area.The re-sults showed that the furrow irrigation quantity and nitrogen application level exhibited highly significant effects on cotton reproductive allocation,and the interaction between them was very significant.The lower reproduc-tive allocation was showed at 5 cm than that at 10 cm of furrow irrigation depth because of its higher branch mass ratio.Proper nitrogen application level could increase the reproductive allocation.The correlation analysis showed that the reproductive allocation was significantly or very significantly negatively correlated with other organ allocations.As the conditions of water and nitrogen improved,the relationship between reproductive al-location and individual biomass changed from negative to positive.
