This part of the book contains the key to each question from every chapter, along with a brief explanation of why this is correct and, in some cases, what the distracters mean.

This chapter describes the effects of weed interference in carrot and suggests non-chemical (including crop rotations and systems, planting timing, false sowing, use of competitive varieties, mechanical or physical method, flame weeding, reduced tillage, cover crops and mulch, and hand weeding) and ...

This chapter focuses on the various factors affecting the success of cassava cultivation, such as seed systems and propagule selection, soil preparation, plant densities and crop establishment, intercropping, weeding, fertilizer application and nutrient disorders and harvesting.

This chapter discusses seed systems and propagule selection, propagation, soil preparation, plant densities and crop establishment, intercropping, weeding, fertilizers and nutrient disorders, and harvesting in yam production.

Aroids can be grown throughout the year in the wet tropics. They are best adapted to high temperatures, a moist environment and high humidity. Evenly distributed rainfall, between 200 and 300 mm/month, is ideal for optimum growth and production. Irrigation is, however, necessary for taro and swamp...

This chapter focuses on the importance of managing the orchard environment for a sustainable sweet cherry production, i.e. fertilizer application, irrigation and crop-weed competition, among others. The influence of some climate-related environmental factors on sweet cherry production are also...
