Brazil is the world’s second producer, followed by Paraguay. The recurrent cycles of surplus supply, low prices, disinvestment in plantations, scarcity of raw materials, high prices -very often linked with international trading terms between producer countries, which result in a greater distortion – have historically acted against a stable supply of the product in terms of quality and quantity.

In Brazilian Amazonia, its increasing abandonment seems to have been caused by two main factors: This aspect of the crop is a challenge to the researcher who must carefully choose the most appropriate direction for the development of the species. Leren is adapted to a tropical climate with alternating rainy and dry seasons.

Prominent among the ecological requirements of this subtropical species are climatic conditions, especially mean annual precipitation and an even distribution of rainfall throughout the year. Known cultivars of I. Generally speaking, the prevailing climatic conditions in the humid tropics – relatively high temperature and humidity throughout the year-are unfavourable for the cultivation of vegetables from a temperate or subtropical climate and, at the same time, encourage the development of pests and phytopathogenic micro-organisms.

Of the amino acids the tryptophan content has not been measuredonly cystine deficiency has been noted; this is of no great importance because Guinea arrowroot is not a food in regular use. The nutritional value of leren has not been thoroughly studied, but the tubers have a starch content of percent and a protein content of allouis.

The physical and chemical qualities of the soil affect Guinea arrowroot’s productivity. As no suitable method has yet been discovered for maintaining the germinating capacity of I. Productivity per plant is between and g. There are high levels of all the other amino acids, chiefly the essential ones. Guinea arrowroot, sweet corn root Caribbean topeetampo, topi-tamboo, topinambour; Spanish: National Academy of Science.

What is its place to be in the agriculture of the future’? Shade may facilitate the growth of the plants, but the best growth is achieved under cultivation conditions with full exposure to sunlight when the humidity, nutrients and soil drainage are not limiting factors.
