This work was performed at Sahl El-Hossinia Agric. Res. Station, El-Sharkia, Governorate, throughout winter seasons of the year 2016/2017 and 2017/2018 to investigate the foliar application of compost tea humic acid, and bio-fertilizer on forage production, seeds, chemical analysis of plant and soil. Using bio-fertilizer; humic and compost tea on plant increases significantly the clover yield. Humic acid recorded that increased of values for yield, yield components and quality as compared by other treatments. Results pointed that forage yield was affected by whole treatments under saline soil conditions. In general, berseem clover treated with humic acid increased the plant height, fresh, dry yield, seeds yield, weight of 1000 seeds, crude protein, fiber fraction, Total carbohydrate, digestible crude protein of forage yield as compared with control. Values of EC and pH of soil were decline due to various traits using foliar application, while the highest rate of EC in soil run to (5.72 dsm-1) at bio-fertilizer. Values of soil properties treated by whole traits were slightly low comparing control (7.72 dsm-1). It is clear that the minimum total costs were those of application of Bio-fertilizer, being 4570 L.E and the maximum total costs were those of the plants received Compost-t rate which was 5180 L.E. Average over all treatments of total costs were 4847.5 L.E for the two season. The highest value of net return per one invested L.E was achieved when using humic acid (5.40 L.E) and Compost-t (4.15 L.E) compared with N fertilization (control 2.63 L.E).

Current study has focused on the hypothesis that augmentation of organic fertilizers with lignocellulolytic fungi could overcome the slow-release issue of nutrients and act as plant growth-promoting fungi (PGPF) for plants against synthetic fertilizers. Two factorial experiments were implemented to study the influence of compost, processed by the addition of lignocellulolytic fungi, against rates of NPK fertilizers on the growth and productivity of cultivated wheat in sandy soil. An inoculum consisted of two cellulolytic fungi, viz Trichoderma harzianum and Trichoderma viride and a ligninolytic fungus, viz Phanerochaete chrysosporium, was used for processing the compost before sowing. Three rates of NPK fertilizers, viz 100%, 75%, or 25% of the recommended dose were combined with processed compost or unprocessed. The results revealed an intensification of overall microbial count and associated activities in the rhizosphere of plants due to processed compost and a medium dose of NPK fertilizers. The dry weight of shoot generally increased in order 100% NPK> 75% NPK > 50% NPK, with a non-significant difference between 100% and 75% treatments when combined with processed compost. Despite the superiority of the full dose of NPK treatment, the divergence between them and 75% NPK fertilizers appeared non-significant when combined with processed compost for straw and grain yield, the weight of 1000 grains, or crude protein. Under the current situation, empowerment to diminish the applied amount of synthetic NPK fertilizers by 25% from the total dose by the incidence of saprobic fungi for more decomposition of organic matter doing a positive priming effect in wheat rhizobiome acting to improve the above-and below-ground parts of plants as a source capacity for high grain yield in eco-friendly and sustainable sound.
