The low productivity of figs in Brazil is usually associated with water and nutrition deficiency. The aim of this work was evaluate the effect of fertigation with doses of nitrogen and potassium on yield and quality of the 'Roxo de Valinhos' figs during cold storage. The field experiment was conducted during two years, and in the last year, the fruits were stored at 0.5° C for fifteen days. The treatments were a combination of doses of of nitrogen (150, 250, 350 and 450 kg ha-1) and potassium (150, 250 and 350 kg ha-1) applied by fertigation. The results showed that doses up to 250 kg ha¹ of N and K in fertigation increased the yield of 'Roxo de Valinhos' figs, and these doses increased the yield among the treatments. Fertigation increased yield of green figs by by 96.7% and ripe figs by 49% compared with the control. The rates of N and K and the application form did not affect the fruit quality during cold storage.
