EFFECT OF BIO-FERTILIZATION ON YIELD OF SAFFLOWER GENOTYPES UNDER WATER STRESS CONDITIONS | ..

The demand for bio agriculture has risen in recent years as a result of its positive environmental impact. In view of the water crisis, breeders are concentrating on genotypes that produce the highest yield under water stress conditions.During two growing seasons, field experiments were performed to compare six genotypes of safflower (Carthamus tinctorius L.) plants to Giza 1, a local cultivar, in the presence and absence of different biofertilization treatments under two levels of drought compared to standard irrigation. The study focused on four key parameters: evaluating output means, estimating tolerance indices (drought tolerance index and yield injury), biofertilization response, and genotype stability across environments. When subjected to high levels of drought, the results showed that Line 10 was the most reliable seed and oil yielder. Drought sensitivity was found in Lines 4 and 12, respectively. Lines 12 and 9 were found to be more stable in a parametric stability study.The breeder will make an effective genotype selection based on these parameters.
