Effect of Climate Change on Fruit and Vegetables Crops
Crop
Changes in Climate
Effect on Crop
Apple
Sharp fall in temperature and rains
during second fortnight of April
(26°C for 17 days against 24°C)
Decrease in productivity.
Poor fruit set.
High temperature scenario advanced
flowering by 16 days.
Lack of chilling requirements leading
to warmer climate
Banana
Dry spell during flower emergence
& fruit sheds
Reduces crop duration
Citrus
Increase in 1-2°C beyond 25-30°C Promotes vegetative instead of flow-
ering flushes
Untimely winter rain
Affects flower initiation and increases
Psylla incidence
Mango
Low temperature (4-11°C)
High humidity (80%) and cloudy
weather during January
Delayed panicle emergence
Temperature regime of 27/13 over
21/4°C persisting for a long time
Higher number of perfect flowers
Unprecedented cold wave
Reduction in yield by 100% and ad-
verse effect on size and quality
Cauliflower
Increase in temperature
Delay in curd initiation
Onion
Temperature above 40°C
Reduction in bulb size
Tomato
High temperature after pollen re-
lease
Decreased fruit set and yield
Potato
High temperature
Yield loss (10-20%) and reduction in
marketable grade of potato tuber
Frost damage
Reduction in tuber yield (10-50%)
depending upon intensity and coinci-
dence with sensitive stages
Cumin
Frost during January (in Rajasthan)
Crop failure
