  • How to grow sunflowers in Botswana?
  • Sunflower requires low humidity and sunny conditions for optimal plant growth and development making it suitable for production in Botswana. Shorter growing season and better cold tolerance makes it suitable for later planting Ideal for crop rotation and cultivated under varying climatic conditions
  • How to produce sunflower oil in a farming system?
  • The first section is the production of sunflower in the farming system that includes all operations, including preparing farms by tillage, planting, controlling diseases and weeds, and harvesting. In other words, all energy inputs entered as LCI in agricultural phase. The next section is extracting sunflower oil by cold press method.
  • What is the best sunflower for Botswana?
  • Recommended cultivar for Botswana is Russian number 4 that matures in 140-150days and grows to a height of 150-165cm. Its seed size is 1-1.5cm long and 0.5-0.8cm wide. Its colour is black, with black grey stripes. The yield potential is 8t/ha (Tsuaneng and Maphanyane 2000). Sunflowers are very susceptible to seed placed fertiliser injury.
  • Is industrial phase better than agricultural phase in sunflower oil production chain?
  • An important result that can be found form energy analysis of this research is the better performance of industrial phase in comparison with agricultural phase in the production chain of sunflower oil. Actually, only about 14% of total energy use belonged to oil extraction process by cold press method.
