Objectives

      1. To examine the interactions of row spacing, seeding rate and seed-placed phosphorus on yield and yield components of spring and winter wheat, barley and durum as well as seedling growth and development, biomass accumulation and P uptake at anthesis.
      2. To determine possible interactions between row spacing, seeding rate and seed-placed phosphorus on grain yield.
      3. To examine the effects of row spacing and seeding rate under conventional fallow cropping conditions in spring wheat and barley.
