Abstract
Two field experiments were conducted throughout 2001/2002 and 2002/2003 seasons in EI-Fayoum governorate to study the effect 0 f inoculation of sugar beet seeds (Beta vulgaris L. cv. Farida) with a mixture of nitrogen fixers namely. Azosp < /em>irillum sp. and Azotobacter sp. and phosphate dissolving bacteria (Bacillus sp.) under different levels of mineral fertilizers i.e. O. 25, 50 and 100% of the recommended rates (RR). 150 kg N Ifed. and 30 kg/ P 2 05 / fed. 0 n photosynthetic pigments. root Quality, yield and its components and anatomical structure as well as to minimize costs of fertilization and environmental pollution. The main results of this investigation could be summarized as follows: Raising the rates of mineral fertilizers from 25 to 100% showed a significant increase in chl.a, chl.b.cbl.a+b and carotenoids until they reached the maximum increase (11.42% in chl.a, 35.12% in chl.b, 20.75% in chl.a-b and 175.51% in carotenoids) with the highest rate of 100% mineral fertilizers treatment compared to the control. The application of mineral fertilizers decreased significantly sucrose and purity percentages in the first season as well as purity and recoverable sugar percentages in the second season in sugar beet plants. Whereas, recoverable sugar and sucrose percentages in the first and in the second seasons were indifferent to those of the control; respectively. On the other hand, TSS% increased significantly with increasing the application of mineral fertilizers from 25 to 100% in the first season while, insignificant effect was recorded in the second season. Such treatment increased significantly i mpurities(Na, K and a-amino nitrogen) content and sucrose loss to molasses % with raising mineral fertilizers levels up to 100% in the first and second seasons except thai of Na in the second season where the differences among mineral fertilizers levels are not significant. The application of the highest level of 100% mineral fertilization gave the highest significant increase being. 84.38 and 85.47% for root length, 78.57 and 64.94% for root diameter. 95.14 and 82.80% for root yield tonlled., 45.71 and 42.11% for top yield ton/fed. and 74.01 and 43.42% for sugar yield tonffed. in both studied seasons; respectively. 6iofertilization treatments had significant effect on chl.a. chl.b, chi. a+b and carotenoids of sugar beet leaves by 1.51. 2.20. 2.17 and 10.68% more than the control; respectively. On the other hand, showed insignificant effect in sucrose, purity and recoverable sugar percentages in both seasons except that of sucrose and purity percentages which were decreased significantly in the first season. Whereas. such treatment showed significant increase in T55% in the first season and no statistical effect in the second season. Biofertilization treatment increased significantly impurities (Na. K and a-amino nitrogen) and sucrose loss to molasses in both studied seasons
