Lower nitrogen use efficiency is major crop productivity limiting factor in semi-arid regions due to its poor organic contents in the soil; our research work is considered to optimize crop productivity by soil and plant chem-biological correction. This study designed and aimed to use soil inoculation with plant growth-promoting rhizobacteria of the genus and foiler application by humic preparations ALCRI-CropHelp and ALCRI-CropHelp-M compared with control and NPK fertilizer under wheat plants in arid regions of Egypt. Experimental data showed that biological correction contributed to a significant increase in wheat yield in the arid regions. The specific results for ALCRI-CropHelp, and ALCRI-CropHelp-M were significantly increased wheat grain yield on 256, 267, and 278 % relative to the control, respectively. Simultaneously, water use efficiency has increased by more than 2.5 times, compared with control and NPK treatments. This effect was achieved due to multiple effects on the metabolism of agricultural plants, and applications of ALCRI-CropHelp and ALCRI-CropHelp-M treatments revealed an increase in the biological yield, spike length, harvest index compared with control and NPK treatments. In conclusion, this study has shown that the ALCRI-CropHelp Az and ALCRI-CropHelp-M foliar applications significantly (P < 0.05) increased grain yield status, N, P, and K in plants, plant growth rate, and plant productivity under growing wheat plant in arid regions. We recommended these treatments for the enhancement of wheat plant productivity in arid regions.
由于半干旱地区土壤有机含量低，氮素利用效率低下是主要的作物生产力限制因素；我们的研究工作旨在通过土壤和植物化学生物校正来优化作物生产力。本研究设计并旨在在埃及干旱地区的小麦植株上，与对照和氮磷钾肥料相比，使用接种属于该属的植物促生根际细菌的土壤，并通过腐殖质制剂ALCRI-CropHelp和ALCRI-CropHelp-M进行叶面施肥。实验数据表明，生物校正有助于干旱地区小麦产量的显著提高。ALCRI-CropHelp和ALCRI-CropHelp-M的具体结果分别使小麦籽粒产量相对于对照显著提高了256%、267%和278%。同时，与对照和氮磷钾处理相比，水分利用效率提高了2.5倍以上。这种效果是由于对农业植物代谢的多种影响而实现的，与对照和氮磷钾处理相比，ALCRI-CropHelp和ALCRI-CropHelp-M处理的生物产量、穗长、收获指数均有所增加。总之，本研究表明，在干旱地区种植小麦时，ALCRI-CropHelp Az和ALCRI-CropHelp-M叶面喷施显著（P < 0.05）提高了籽粒产量状况、植物中的氮、磷和钾含量、植物生长速率和植物生产力。我们推荐这些处理方法以提高干旱地区小麦植株的生产力。
