Management Strategies Under Different Draught Conditions

Depending upon time and intensity of moisture stress, management strategies have to be adopted. Moisture stress periods are usually classified be (i) parly season moisture stress (ii) mid - season moisture stress (iii) terminal stress.

Early season stress:
Early season moisture stress occurs due to the failure of rains after sowing of crops /cropping systems or delayed start of rainy season. If produced dey spell occur immediately after sowing the seedlings may water.
Mid reserve stress may occur due to the period of monsoon after mateblislwent of crops. Under these situations adoption of frequent interculturing aerations use of organic mulches, lop dressing of outrage after rained of moisture steps formation of dead furrow red  such dry spells in the same season, the likelihood is quite high Bhavanisagar (77%), while it is les at Solapur (15% once in 7 years) and the chance at Hyderabad is zero.
Extension advisors, field agronomists and district agriculture officials can use such information by using the data from their regional metrological stations in order to time tune the blanket recommendations to suit particular conditions.
