Direct and residual phosphorus effects on grain yieldphosphorus uptake relationships in upland rice on an ultisol in West Africa

Phosphorus (P) deficiency is a major constraint to crop production on highly weathered, lowactivity clay soils in the humid zone of West Africa. Past research suggested a linear relationship between grain yield and P uptake over a range of fertilizer P applied to upland rice cultivars. However, there is lack of information on how these relationships are affected by the long-term fertilizer ...

An approach based on a linear rate of increase in harvest index Deficiencies in the HI approach, however, may be (HI) with time after anthesis has been used as a simple means to predict grain growth and yield in many crop simulation models. When associated with use of a constant rate of HI increase applied to...
