e0“The response of Ibs-solids yield to N rate was described by a quadratic plateau model where the critical N rate varied from 76% of the full N rate for conventional fertilizer (at 26.9 Ibs-solids/ tree) to 100% of the full N rate for Prokote Plus (34.0 Ibs-solids/ tree), Nutricote, and Meister.”

Other claims from this paper (9)
- Intervention effect Prokote Plus, Nutricote, and Sierra produced 4.9 to 4.8 boxes per tree over four years, versus 4.3 with conventional fertilizer.
- Intervention effect Prokote Plus and Sierra produced higher solids yield than conventional fertilizer.
- Intervention effect Prokote Plus and Sierra produced higher gross returns than conventional fertilizer.
- Intervention effect Prokote Plus exceeded Escote in fruit and solids yield.
- Intervention effect Prokote Plus exceeded Escote and Meister in dollar return.
- Observation The critical nitrogen rate for conventional fertilizer was 76% of the full rate at 26.9 pounds solids per tree.
- Intervention effect At the full nitrogen rate, controlled-release fertilizers cost four times as much as conventional fertilizer.
- Intervention effect At the full nitrogen rate, controlled-release fertilizers had 15% greater return.
- Recommendation Current controlled-release fertilizer prices make them uneconomical as the main nutrient source for citrus.
