Resumo
The citrus agribusiness in Goiás has a great potential, but there are few studies on the segment of
seedlings production. This work was carried out
aiming to evaluate the nutrition of citrus nursery during their
development in protected using fertirrigation. The rootstock was used lemon and clove to orange pear scion variety. The
experimental design was completely randomized, with a split plot in time, and the plots (root, stem, leaf and whole plant)
and subplots the stage of development (30 to 360 days after emergence) with three replicates, for evaluating data
biometric, dry matter production and accumulated levels of nutrients depending on age of the plant. The N, Ca, Mg and Cu
were the nutrients that are accumulated more in leaves. P has had its greatest concentration observed in the stem. K, S, Fe,
Mn and Zn are accumulated in greater quantity in the roots. The levels of accumulated nutrients were: N – 1.058, P –
0.236, K – 0.632, Ca – 0.871,
Mg – 0.143 and S – 0.105 g plant -1 . The micronutrients were: Cu - 0.2036; Fe - 2.1188,
Mn - 0.8694 and Zn - 0.0534 mg plant -1 .
