Balance design for robust foliar nutrient diagnosis of “Prata” banana (Musa spp.) [PDF]

Scientific Reports, 2018
AbstractThe “Cavendish” and “Prata” subgroups represent respectively 47% and 24% of the world banana production. Compared to world average progressing from 10.6 to 20.6 t ha−1between 1961 and 2016, and despite sustained domestic demand and the introduction of new cultivars, banana yield in Brazil has stagnated around 14.5 t ha−1mainly due to nutrient ...
