Virtual Academy for the Semi Arid Tropics Course on Coping with Drought About Drought A direct outcome of the shortage in rainfall leading to drought situation has been on crop production. Drought not only affects crop/crops in individual farmer’s field but also damages the crops grown in the entire region exposed to the drought. Lesson 2: How drought affects agriculture?

Virtual Academy for the Semi Arid Tropics Course on Coping with Drought About Drought Lesson 2: How drought affects agriculture? The loss in crop yields in the farmer’s field and in the region ultimately reflect in the crop production in the country as a whole.

Virtual Academy for the Semi Arid Tropics Course on Coping with Drought About Drought The extent of damage to crop/s depend on the stage of the crop and the timing, period and severity of drought. Lesson 2: How drought affects agriculture? Early-season Drought Mid-season Drought Late-season Drought
5
Virtual Academy for the Semi Arid Tropics Course on Coping with Drought About Drought Effect of delayed rains and early season drought: Delay in field operations Delay in sowing or untimely sowing of crops Poor germination Low crop stand Week seedlings Susceptibility to pests and diseases. Lesson 2: How drought affects agriculture? Poor germination and crop stand
6
Virtual Academy for the Semi Arid Tropics Course on Coping with Drought About Drought Effect of mid-season drought Poor tillering No or delayed flowering Drying of pollen Increased costs for irrigation Higher susceptibility to pests and diseases. Lesson 2: How drought affects agriculture? Delayed flowering in sorghum
7
Virtual Academy for the Semi Arid Tropics Course on Coping with Drought About Drought Effect of late-season or terminal drought Poor seed/pod/ fruit setting Low crop yields Low quality produce Increased costs for irrigation Susceptibility to pests and diseases. Lesson 2: How drought affects agriculture? Drought affected sorghum with very low yields
