Agriculture Climatic Conditions Flashcards
Wheat:
Rainfall:
80 cm
- Excess of Moisture
- retards the growth.
- The winter rain is beneficial (northern plains)
Wheat:
Temperature:
10 to 15 sowing
20 to 25 harvesting
- Low temperature while growing,
- Gradual increase is better than sudden increase in temperature
- For the development of the grains
Mustard:
Temperature:
10 to 20 (cool climate)
Mustard:
Rainfall:
25 to 40 cm
Pulses:
Temperature:
20 to 25
Pulses:
Rainfall:
- Mostly Rainfed Conditions but some irrigation is provided
50 to 75 cm
Groundnut:
Temperature:
20 to 25 (Dry weather during ripening)
Groundnut:
Rainfall:
50 to 100 cm (Well distributed, Light to moderate) -> - Moderate to light
- Well distributed
- Prolonged Drought, Continuous rains, Stagant water, Frost
- HARMS the plant adversely
- Grown under irrigation
- TN and Maharastra
Sugarcane:
Rainfall:
- 100 to 150 cm
- Irrigation:
- Necessary if lower rainfall and in Higher rainfall, during long dry spells
- Heavy Rain:
- Sucrose Decreases
- Rainfall Defficiency:
- Fibrous Crop
Sugarcane:
Temperature:
20 to 26 (Growth Starts at Mean of 20, Accelerates till 24,
stops at 26)
Cotton:
Rainfall:
50 to 75 cm
>85 cm → Destroys the crop
- Earlier stages: Sufficient rainfall
- After flowering: Sunny and Dry weather
- Rainfall during ball opening and harvesting is Harmful
- Makes them vulnerable to pests and diseases
Cotton:
Temperature:
21 to 30 → July to September
>26 → Ocotber
Min > 20 → Retard plants growth
- 200 frost free days necessary
- For plants to mature
- Extremely sensitive to frost
Tea:
Rainfall:
- Abundant Rainfall
- At least 150 cm
- Well distributed throughout the year
Tea:
Temperature:
- Max temp. 24 to 30 degrees
- Growth is retarded
- 18(min) to 24(max) degree
- Shade loving plant
- Develops more vigorously in shade
Rice:
Temperature:
Flowering and Fertilization: 16 to 20
Ripening: 18 to 32
above 35 → Grain retention and Grain filling
- Different altitudes given temperature is satisified
