Crop Planning For Aberrant Weather
Crop production in dryland suffers from in stability due to aberrant weather condition from time to time. Delayed monsoon results in non sowing of traditional kharif crops which accounts for nearly 25 to 30% of the total area under crops. So also early withdrawal of monsoon interferes sowing of Rabi a crop which is main constraint of crop production in the region. Similarly, breaks in monsoon also after crop production adversely year 1972 was the lowest rainfall year which resulted in total failure of both Kharif and rabi crops under dry lands.
