Foreword

Potato (Solanum tuberosum) is the world’s fourth most important food crop after maize, wheat and rice with 377 million tonnes of tubers produced from 19.2 million hectares of land, in over 160 countries, in 2016 (http://faostat.fao.org). Furthermore, as a result of steady increase in its demand in recent years, over 50% of production is now in Asia, with China and India the largest contributors. Harvestable potatoes are produced in 100 to 120 days, and therefore they proved suitable for double cropping and intercropping systems. Globally, its average dry weight yield (3.92 t/ha) compares favourably with the three cereals (3.88 t/ha) as a result of a higher harvest index of 0.75 compared with 0.5. Likewise, protein content at 10% of dry weight equals that of most cereals with prot
