“…Also, application of 40 mg N kg -1 soil of mineral N fertilizer mixed with Azotobacter + Azospirillum in presence of humic acid (50 L fad. -1 ) realized the greater values of grain and straw yields, N, P and K uptake by wheat (El-Hamdi et al, 2012).…”

Biological experiment was conducted in the clay and sandy soils to study the effect of inorganic, organic and bio fertilization on growth and yield components as well as N, P and Kuptake by wheat plants. Ammonium sulphate (N) was added at the rates of 25 [50% the recommended dose (RD)] and 50 (100% RD) mg N kg-1 soil, while ordinary superphosphate (P 1) and rock phosphate (P 2) were applied at the rates of 9.72 (50% RD) and 19.44 (100% RD mg P kg-1 soil. Potassium sulphate (K 1) and feldspar (K 2) were added at the rates of 20.8 (50% RD) and 41.5 (100% RD) mg K kg-1 soil. The organic materials i.e. clover straw (CS), sunflower seed teflon (ST) and banana peel (BP) were added at a rate of (0.5%). Some wheat grains were inoculated by biofertilizers i.e. nitrobein (nit), phosphate dissolving bacteria (PDB) and potassiumage (Pot). The results showed that the treatments of [50% RD (NP 1 K 1) + CS + ST + BP + Nit + PDB + Pot] gave the greatest values of the straw and grains dry weight, biological yield and harvest index, N-uptake by grains and P-and K-uptake by straw and grains if compared to the other treatments in both soils under study. Wherease the highest 1000 grains weight was observed with the treatment of [50% RD (NP 2 K 2) + CS + ST + BP + Nit + PDB + Pot] in the clayey soil and [50% RD (NP 1 K 1) + CS + ST + BP] in the sandy soil compared to the other treatments. The greatest values of N-uptake by straw were recorded with treatments of [50% RD (NP 1 K 1) + CS + ST + BP] in the clayey soil and [50% RD (NP 1 K 1) + CS + ST + BP + Nit + PDB + Pot] in the sandy soil compared to the other treatments. Finally, it could be concluded that the use of 50% of the recommend dose of the most mineral fertilizers (NP 1 K 1) mixed with organic materials (CS + ST + BP) and biofertilizers (Nit + PDB + Pot) may reduce the mineral fertilization (NP 1 K 1) dose, production cost and environmental contamination.

“…In addition, humic acid may improve the assimilation of major and minor elements, enzyme activation and protein synthesis and increasing dry matter accumulation which consequently increased yield and quality (Ulukan, 2008). In this connection, El-Hamdi et al (2012) showed that number of grains/spike, spike length, 1000-grain weight, grain and straw yields/fad., were significantly increased due to humic acid application.…”

“…Humic acid reduce soil erosion via increasing the cohesive forces of the fine soil particles, promoting of elements chelation and hence, this might play an important role in enriching soil fertility and availability of nutrients. In this respect, many investigators reported significant increase in yield and yield components of wheat due to the application of humic acid (Antoun et al, 2010;Khan et al, 2010;El-Hamdi et al, 2012;Bakry et al, 2013;Tufail et al, 2014;Radwan et al, 2015;Anwar et al, 2016). Moreover, Kandil et al (2016) and Manal et al (2016) showed that higher averages of spike length, number of grains/spike, grain weight/spike, 1000-grain weight as well as grain, straw and biological yields of wheat were obtained by application of humic acid, while harvest index was significantly decreased.…”

to investigate the effect of three rates of humic acid application (0, 2 and 4 kg humic acid/fad.) and five nitrogen fertilizer levels (0, 30, 60, 90 and 120 kg N/fad.) on bread wheat (Triticum aestivum L. cv. Sids 12) grown in sandy soil under sprinkler irrigation system. Results of the combined analysis indicated that application of humic acid at 2 kg/ fad., significantly increased plant height (cm), flag leaf area (cm 2), spike length (cm), number of spikes/m 2 , straw yield (ton/fad.) and harvest index as compared to control treatment. Furthermore, flag leaf chlorophyll content (SPAD), number of grains/spike, weight of grains/spike (g), 1000-grain weight (g), grain and biological yields (ton/fad.) showed significant increase due to raising humic acid application up to 4 kg/fad. On the other hand, it was found that plant height, spike length, number and weight of grains/spike, number of spikes/m 2 , 1000-grain weight, straw yield and harvest index were significantly increased by increasing nitrogen fertilizer levels up to 90 kg N/fad. Whereas, flag leaf area, flag leaf chlorophyll content, grain and biological yields per fad responded to each N increment up to 120 kg N/fad. Most studied traits were significantly affected by the interaction between humic acid and nitrogen fertilizer levels. It could be noticed that, application of humic acid resulted in reducing the requirement to N fertilizer application. The highest grain yield (16.25 ardab/fad.) was achieved by soil application of 4 kg humic acid with 90 kg N/fad.
