Guinea arrowroot is normally grown in small areas where subsistence farming is frequently carried out in association with cassava, plantain or fruit-trees. Leren usually reproduces itself through rhizomes which produce shoots and new plants. Root – cooked[ 46 ]. Productivity of the tuberous roots is quadrupled if they are grown on plots treated with organic fertilizers fruit and vegetable waste. Methionine found in Root ppm. At calaghea, in communities further away from towns in Amazonia it is rare to meet a grower who still keeps Guinea arrowroot in his garden.

In spite of the marked weight loss percent after ten weeks – the best method of storing the tubers is to put them in the vegetable fibre baskets which farmers use to store roots, tubers and meal, and which are lined on the outside with dry leaves.

It is improbable that its place is in monoculture with an intensive use of inputs and with high yields, and it is probably only a matter of time before it is completely abandoned in that context. Guinea arrowroot requires soils of medium texture because very clayey soils impair the development of the tuberous roots while in sandy soils its growth is deficient.
