Abstract
Four recent fertiliser response trials on marine and riverine soils are discussed. Averaged over the trial period the dominant yield response is to nitrogen as high as 43 increase in three trials followed by phosphorus maximum of 6 increase in two trials and potassium up to 9 extra yield in one trial. Nitrogen input is also linked to vegetative parameters such as rachis length leaf area leaf dry matter and leaf production rate. Interestingly the incidence of basa; frond fracture is clearly correlated to nitrogen rates. However the greater leaf area index in the high nitrogen plots offset any loss of effective leaf area resulting from frond fracture. Knowledge of yield and vegetative response to applied fertilizers on our soils is vital for effective nutrient and canopy management practices as well as in selecting the optimal planting densities.
