The experiment was conducted to evaluate the nutrient utilization ability of sweet
orange (Citrus sinensis L. Osbeck) budded on five rootstocks (viz., Sathgudi, Rangpur
lime, Cleopatra mandarin, Troyer citrange, and Trifoliate orange) in Alfisols at the
experimental farm of the Citrus Improvement Project, S. V. Agricultural College Farm,
Tirupati, Andhra Pradesh, India. Results of the study revealed that all the five rootstocks
showed differential behaviors in terms of nutrient absorption from the soil. Rootstocks
exhibited significant variation in the leaf content of potassium (K), copper (Cu), manganese
(Mn), and boron (B) at all the three stages of sampling. Concentrations of the
following key nutrient elements significantly varied: phosphorus (P), calcium (Ca),
magnesium (Mg), zinc (Zn), and Cu at stage 1; K, Ca, Mg, Zn, iron (Fe), and Mn
at stage 2; and nitrogen (N), P, Zn, Fe, and B at stage 3. The performances of
rootstocks in terms of relative nutrient accumulation indices (RNAIs) were in the order
of Sathgudi (1.00) > Rangpur lime (0.98) > Cleopatra mandarin (0.96) > Trifoliate
orange (0.76) > Troyer citrange (0.69). The present study clearly demonstrated that citrus
rootstocks employed had differential nutritional behavior and different abilities to
utilize plant nutrient elements. Thus, the findings of the present study and the methodology
adopted can help the horticultural breeders and nutritionists choose the best
rootstock/scion combination having the desirable traits of nutrient utilization ability
and also to plan effective fertilizer schedule programs for achieving greater yields.
