Vegetable Crop Production

Vegetable Crop Production TPSS 401 Spring 2006 FINAL EXAM Study Guide

1. Be able to match the scientific and common names of all the vegetables in each of these Families that were mentioned class: Solanaceae, Cucubitaceae, Brassicaceae, Apiaceae, Compositeae, Chenopodaceae, Fabaceae.

2. Identify the general and unique plant requirements for each of the following families as discussed in class: Solanaceae, Cucubitaceae, Brassicaceae, Apiaceae, Compositeae, Chenopodaceae, Fabaceae

3. The growth of which one of the following vegetables is generally least retarded by moderately cool (e.g. 15-20 C) temperatures: Solanum melogena, Lycpersicon lycopersicum or Capsicum annum.

4. Describe the relationship between flowering and air temperature in Lycpersicon lycopersicum.

5. What does flea beetle damage look like on eggplant?

6. Which Capsicum species is the most commercially important worldwide.

7. What group of compounds provides Capsicum sp. with pungency? Where are these compounds located in the fruit? What are scoville units? Which Capsicum species boasts genotypes with the greatest pungency?

8. Name a group of bioactive compounds for each of these families: Solanaceae, Cucubitaceae, Brassicaceae, Asteraceae, .

9. Why is the recommended soil pH for the production of some crops often at the high or low end of their pH tolerance range.

10. During which period(s) of crop development is it most critical to avoid plant moisture stress? Why?

11. What will high N applications to mature tomato plants do to flowering?

12. What are some of the benefits of relatively relative crop spacing. Why do broccoli growers frequently prefer high plant densities?

13. Do “Asian” and “Italian” eggplants belong to the same species? How about “Asian” and “European (head)” cabbage? 14. Which vegetable family is particularly susceptible to boron deficiency?

15. What will frequently induce micronutrient deficiency in vegetables grown in a soil with adequate micronutrients for growth and a relatively low pH (e.g. 5.5), which should not interfere with micro availability?

16. Describe sex expression in the Cucurbitaceae and discuss the influence of environment on sex expression of Cucurbits.

17. Rank the following rotations from best to worst potential for disease control (1= best, 2=intermediate, 3= worst). Justify your answer.

 Rotation A = Cucumis sativus – Momordica charantia – Lanatus citrullus  Rotation B = Momordica charantia – Apium graveloens – Beta vulgaris  Rotation C = Brassica oleracea- Phaseolus vulgaris- Raphanus sativus

18. List general harvest and post harvest strategies employed to maximize and extend produce quality.

19. Compare and contrast the pros and cons of the following marketing strategies in Hawaii: 1) selling to a wholesaler, 2) selling direct to restaurants, 3) selling through a “CSA”

20. What factors discussed in class can limit the appeal of CSAs to a majority of consumers? What strategies may be employed by the grower(s) and/or manager(s) of a CSA to maximize consumer appeal?
