Response of fig-tree orchard (Ficus carica L.) under irrigation and nitrogen levels at the Ilha Solteira (SP) region

The study had the purpose of evaluating the effects of irrigation and nitrogen fertilization levels upon fig-tree orchards (harvest 1991/1992). A randomized split-plot block design was installed with six irrigation levels (0, 25, 50, 75,100 and 125% of Class A Pan Evaporation) and six nitrogen levels (0, 150, 300, 450, 600 and 750 g/plant), with four repetitions. According to the statistical analysis, significant effects of water supply were verified on ripe fruit harvest, total productivity, branch lenght and ripe fruit heigth and diameter. Nitrogen fertilization effects on ripe fruit harvest and branch lenght were also detected.
