10. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your answer is partly correct. Black soils are vertisols and also fine textured soils because of higher clay content in these soils. The correct answer is: Sorghum can be grown in any fertile and well drained soil.

11. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your answer is correct. Sorghum can be grown in any fertile and well drained soil.

12. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your are right. Sorghum plants tolerate saline and alkaline soils and do well in the soil pH range of 6 to 8.5.

13. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your answer is not correct. The correct answer is: Sorghum plants tolerate saline and alkaline soils and do well in the soil pH range of 6 to 8.5.

14. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements If you are not sure, the answer is Sorghum plants tolerate saline and alkaline soils and do well in the soil pH range of 6 to 8.5.

15. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your are right. Soils infested earlier with striga should be avoided for sorghum cultivation.

16. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your answer is not correct. Downy mildew, virus, and congress weeds are not serious problems in sorghum soils. The correct answer is: Soils infested earlier with striga should be avoided for sorghum cultivation.

17. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your are right. Sorghum can withstand drought but not very cool temperatures.

18. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your answer is not correct. The correct answer is: Sorghum can withstand drought but not very cool temperatures.

19. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements If you are not sure, here is the answer. Sorghum can withstand drought but not very cool temperatures.

20. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your are right. Poor emergence and seedling growth may result if planted before soil temperatures reach 35 o C.

21. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your answer is not correct. The correct answer is: It is true that sorghum is sensitive to soil temperature at germination stage. Poor emergence and seedling growth may result if planted before soil temperatures reach 35 o C.

22. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements If you are not sure, here is the answer. It is true that sorghum is sensitive to soil temperature at germination stage. Poor emergence and seedling growth may result if planted before soil temperatures reach 35 o C.

23. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your are right. The ability of sorghum to grow in drier environments is due to waxy coating on leaves.

24. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your answer is not correct. The correct answer is: The ability of sorghum to grow in drier environments is due to waxy coating on leaves.

25. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your are right. The ability of sorghum to grow in drier environments is also due to many adventitious roots produced by sorghum plants.

26. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your answer is not correct. Sorghum has no tap root system. The correct answer is: The ability of sorghum to grow in drier environments is also due to many adventitious roots produced by sorghum plants.

27. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module 3 Soils and Climatic Requirements Your answer is not correct. Brace roots in sorghum serve only for anchoring the plant. The correct answer is: The ability of sorghum to grow in drier environments is also due to many adventitious roots produced by sorghum plants.
