Wheatgrass juice is the young grass of the common wheat plant (Triticum aestivum) freshly juiced for human consumption. The objective of the investigation performed was to assess the nutritional value of wheatgrass juice under laboratory and open field conditions at two different cuts. Protein, chlorophyll contents, minerals content (Ca, Fe, Mg, Zn and Se) and amino acids content as well as phytochemical constituents were determined. Grown wheatgrass at laboratory caused an increase of the protein content of its juice over open field condition. High chlorophyll content was observed under open field especially at second cut. Most of minerals content underwent to increase under open field except Mg content. Aspartic acid was recorded the highest amino acid in both laboratory and open field. Total essential amino acids were increased under open field condition at both first and second cut followed by first cut at laboratory. No big changes of natural phytochemicals constituents can shown between laboratory and open field condition while it was more pronounced compare with wheat seeds. The study suggested that sprouting wheat seeds at laboratory and open field improve the nutritional value of grass juice with preferably to laboratory condition especially at first cut and for saving agricultural land.

Two field experiments were conducted at Experimental Farm of Tag El-Ezz, Agricultural Research Station, Dakahlia Governorate, Egypt, during two successive summer seasons of 2019 and 2020 to study the improving efficiency of different P mineral sources with bio, and organic additives as combined treatments on growth performance, quantitative and qualitative productivity of soybean plants (Glycine max L., cv. Giza 111). A split-plot design with three replicates was used, representing three sources of P fertilizers (control, Ordinary superphosphate OSP, and Mono ammonium phosphate MAP as the main plots, six bio and organic treatments (control, arbuscular mycorrhizal fungi AM, vermicompost V, potassium humate KH, AM+V, and AM+KH as the subplots. The results were collected briefly as follows: MAP gave the highest values of vegetative growth, yield, its components, and seed quality compared to (OSP) or control. AM+KH had the best-aforementioned adjectives compared to other bio and organic additives, where the plants fertilized with AM+V came in the second-order followed by KH then V, and lately AM alone. The combination of MAP and AM+KH was the superior treatment effect on all studied traits compared to the other treatments, the highest P use efficiencies values and (benefit: cost) ratio were achieved from this reaction. The available N, P, K and pH value of soil after the harvest of soybean were improved significantly due to the integration of inorganic fertilizers with bio and organic fertilizers.
