Effect of Biochar Application to Fertile Soil on Tomato Crop Production under Saline Irrigation Regime

Biochar application is a promising sustainable strategy for enhancing soil properties thus crop production. However, biochar to certainly alters its biological and physical properties, could require extra costs. Therefore, suitability agroecosystems must be proactively estimated. The advantage of addition poor fertile or weathered soils has been well studies, however, feasibility under low quality (saline) irrigation water was not frequently studied. Consequently, this work investigates the hypothesis whether at rate 4.8 tons/ha (Nile Valley, Giza, Egypt) would ameliorate negative effects saline regime (3000 ppm) on tomato soil. results two seasons experiments showed that significantly reduced yield by an average reduction ratio 51%, compensate such reduction. Furthermore, did reduce accumulated Na+ in fruits roots. Tomato produced from biochar-added were lower TSS levels (41.7% ratio) yet larger diameter approximately 1.5-fold increase. Interestingly, into greatly promotes length stem-borne lateral roots elevates expression LeNR (encodes nitrate reductase enzyme) leaves fresh regime. For enhanced either conditions. Collectively, it assumed Nile Valley Egypt alleviate affected applied
