Drought conditions (Helianthus annuus L.)

After nitrogen, phosphorus and potassium, sulphur is the fourth nutrient, whose deficiency is widespread in India. Sulphur deficiency is observed primarily due to high crop yield and therefore higher rate of sulphur removal by crops, and lesser use of sulphur-containing fertilizers. Boron foliar sprays seemed to overcome the deleterious effects of drought by overcoming the drought-related molecular responses and consequently appeared to meliorate sunflower growth under insufficient water conditions.

The phenomenon of staygreen nature with desired root traits is important consideration in drought tolerance breeding. The experiment was conducted using 28 inbred lines (including 2 checks) which were developed by mutation breeding from AICRP on oilseeds, MARS, AUS, Dharwad, and on the basis of SPAD reading and stay green nature, which were essential to extract moisture from deeper layer of the soil profile.
