The mineral composition of the Robusta banana plant IV. The application of fertilizers for high yields
Mineral composition of the Robusta banana plant at different stages of growth is used to compute fertilizer requirements for high yields (50 tonnes per ha) on nutritionally poor sites. Emphasis is laid on the difference in fertilizer requirement between the first and subsequent years. A fertilizer composition of 9:9:35 was found suitable for all stages of the banana field but the amount required decreased from the first year to each subsequent year by 87 per cent. Mangesium and calcium requirements, even in deficient soils, are small.
Consequences in respect of pruning, choice of planting material and timing of fertilizer application are discussed.
Calculated fertilizer requirements are compared with those derived from field fertilizer trials.
