Pivotal Role of Bio and Mineral Fertilizer Combinations on Morphological, Anatomical and Yield Characters of Sugar Beet Plant (Beta vulgaris L.)

Two field experiments were conducted at Sakha Research Station, Kafr El-Sheikh Governorate, Egypt during 2012/2013 and 2013/2014 seasons, to study the effect of mineral and bio-fertilizers as well as their combinations on morphology, anatomy, yield and quality of sugar beet. Bio-fertilizers were phosphorine, cerealine and yeast; however, mineral fertilizers were 50, 75 and 100% from recommended dose of nitrogen, phosphorus and potassium as well. The results revealed that the combined treatments of phosphorine, cerealine and yeast with 75% from recommended dose of NPK and phosphorine, cerealine and yeast with 50% from recommended dose of NPK showed the highest values of most studied characters; root length and diameter, shoot and root fresh weights, TSS, sucrose and purity percentages as well as root and sugar yield/fed in both studied growing seasons as compared with using each treatment alone as well as control treatment (100% NPK). However, the highest values of chlorophyll a and b, sucrose% as well as purity% were resulted from treatment of phosphorine, cerealine and yeast with adding 50% NPK in the two growing seasons. Interestingly that anatomical characters of root and leaf such as root diameter, number of vessels/bundle in root as well as leaf lamina and midrib thickness were increased with application of phosphorine, cerealine and yeast + 50% NPK. It can be concluded that application with phosphorine, cerealine and yeast as bio-fertilizers combined with 50% NPK as mineral fertilizers from recommended dose led to maximize sugar beet productivity and reduce the cost of mineral fertilization which being harmful for human health and cause environmental pollution.
