1. After successful completion of this Module, you have learned to answer the following questions for each of the 6 crops discussed in this Module: 1. How much of rainfall is required to provide sufficient moisture for good growth and yield of these crops? 2. What are the critical stages of growth of these crops to rainfall (moisture)? 3. What temperature conditions are suitable for different growth stages of these crops?

2. The 6 Lessons in this Module cover the following crops. Lesson 1: Millets (Sorghum, Pearl Millet, etc.) Lesson 2: Groundnut Lesson 3: Pigeonpea Lesson 4: Chickpea Lesson 5: Maize Lesson 6: Rice Virtual Academy for the Semi Arid Tropics Course on Crop-Weather Relationships Module V: Climatic Requirements of Some Crops

3. Virtual Academy for the Semi Arid Tropics Lesson 5: Climatic Requirements of Maize crop Course on Crop-Weather Relationships Module V: Climatic Requirements of Some Crops After successful completion of this Lesson, you will be able to answer: 1. How much of rainfall is required to provide sufficient moisture for good growth and yield of Maize crop? 2. What are the critical stages of growth of Maize crop when rainfall (moisture) is important? 3. What temperature conditions are suitable at different growth stages of Maize crop?

4. Virtual Academy for the Semi Arid Tropics Lesson 5: Climatic Requirements of Maize crop Course on Crop-Weather Relationships Module V: Climatic Requirements of Some Crops Water relations: Requires considerable amount of moisture; 50-75 cm of well-distributed rain is conducive to proper growth; Expends water economically and relatively drought - resisting crop.

5. Virtual Academy for the Semi Arid Tropics Lesson 5: Climatic Requirements of Maize crop Course on Crop-Weather Relationships Module V: Climatic Requirements of Some Crops Water relations: After germination and up to tasseling stage crop stands less moisture; Requires more moisture during reproductive period; Requires less moisture when developing towards maturity.

6. Virtual Academy for the Semi Arid Tropics Lesson 5: Climatic Requirements of Maize crop Course on Crop-Weather Relationships Module V: Climatic Requirements of Some Crops Temperature: A warm weather crop; Requires a mean temperature around 22 o C and night temperature above 15 o C; Requires considerable warmth from germination to flowering;

7. Virtual Academy for the Semi Arid Tropics Lesson 5: Climatic Requirements of Maize crop Course on Crop-Weather Relationships Module V: Climatic Requirements of Some Crops Temperature: Cultivation not possible when day temperatures are less than 19 o C and night temperatures during the first 3 months falls below 21 o C; Noon temperature above 35 o C for several days destroys pollen and yields are drastically reduced.

8. This concludes Lesson 5: Climatic Requirements of Maize crop - in this Module. The last Lesson in this module is about the Climatic Requirements of rice crop.
