Abstract
Concerning the effect of compost and mineral fertilizer on soil available NPK, and some soil properties. Data in three studied experiments indicated that the highest increase in soil available NPK was achieved with S100%, while the highest increase in HW%, OM%, HC and total count of bacteria were recorded with O100%. Regarding to the effect of biofertilizers, the highest increase in soil available NPK, HC, OM%, and total count of bacteria were obtained with microbin + phosphorin, while the highest value in HW% was found with microbin individually, these results conducted in three studied experiments. The interaction effect in the first experiment showed that the highest increase in soil available NPK was detected by applying microbin + phosphorin mixed with S100%, and the same trend was found in the field experiment. In sandy soil the highest N, and P were taken the same previous trend, but the highest increase in K was recorded with microbin + phosphorin + M100%. The highest significant increase in soil organic matter in three studied experiment was achived with microbin + phosphorin mixed with (S25%+O75%). Soil hygroscopicwater in the first experiment achived highly significant increase with microbin + phosphorin + S100%. On the other hand the highest value in the sndy soil was detected with microbin + O100% but in field experiment the highest increase occurred with microbin + phosphorin + O100%. The same trend was found in hydraulic conductivity and total count of bacteria in all studied experiments. Plant analysis in all studied experiments showed that the highest increase in growth parameters (plant height, spick height, number of tillers, fresh and dry weight) and also in straw and grain yield were achieved with S100%. In the first experiment at booting and harvesting stage the highest increase in N and P concentration were obtained with S100%, while K concentration achieved with S75%+O25%. In sandy soil and field experiment (clay soil) the highest significant increase in NPK and their uptake were recorded with S100%. In the three studied experiment the highest increase in plant height, spick height, number of tillers, fresh and dry weight and also grain and straw yield were achived with microbin + phosphorin in both clay and sandy soil, and the same trend was achieved in NPK concentrations and their uptake. The interaction effect in the first experiment showed highly significant increase in plant height, and fresh and dry weight with microbin + phosphorin + S100%, and the same results were found in the sandy soil and firled experiment (clay soil). Straw and grain yield showed the same trend in the first experiment while in the sandy soil and field experiment (clay soil) the highest increase were recorded with microbin + S100%. The interaction effect in the first experiment on plant nutrients and its uptake showed that the highest significant increase in N and P concentration at booting stage and NPK at harvesting stage were conducted with microbin + phosphorin + S100%, while K concentration at booting stage recorded highest increase with phosphorin + S100%. On the other hand in sandy soil and field experiment tgeh highest value in NPK at booting and harvesting were recorded with microbin + phosphorin + S100%. In studied experiments the highest increase in NPK uptake was achived with microbin + phosphorin mixed with S100%. Data in studied experiments showed that the addition of bio, mineral and organic fertilizers have no significant increase in NO3 accumulation . Protien content in the presence of mineral, and organic gave the highest increase with S100% in the studied experiment, However in the presence of biofertilizers the highest increase in protein content was recorded with microbin + phosphorin. The interaction effect showed highly significant increase with microbin + pphosphorin + S100%.
