BERSEEM CLOVER PRODUCTIVITY IN THE PRESENCE OF A COMBINATION OF BIOFERTILIZERS, ORGANIC FERTILIZER AND BIOCHAR UNDER SANDY SOIL CONDITIONS

AbstractSeveral studies have shown that berseem clover is one of the most important winter leguminous crops as fodder for animals due to its high content crude protein. In Egypt, cultivation abundant in soils whether ancient or reclaimed soils. This study was designed evaluate effect biofertilizers on productivity cultivated under sandy soil conditions Ismailia Research Station, Governorate. To reach such aim, an identified actinomycete strain (Streptomyces luteogriseus-08) used with a mixture biochar, and organic fertilizer several different treatments compared rhizobia. The experimental results revealed percentages protein two cuts indicated 2nd cutting always higher percentage than 1st cutting. On planting treating, microbial total counts, dehydrogenase activity NPK contents were developed samples collected from 15 control-soil sample. addition, containing rhizobium biofertilizer showed rhizobium-free treatments. presence more suitable improving growth plants biochar. Combination Rhizobium legumin Sarum bv. trifolii , Streptomyces luteogriseus-08, fertilizer, biochar low nitrogen (T16 treatment) gave highest numbers nodules, dry weight fresh nodules. Dry weights shoots, (%) expected yield (Ton/Feddan) T16 control other 14
