Response of some wheat cultivars to nano-, mineral fertilizers and amino acids foliar application

الملخص EN

Wheat is the major source of food for human nutrition and a part of daily dietary need in one form or more.

There is need to increase its productivity vertically and horizontally.

In order to improve productivity of three wheat cultivars, nano- technological fertilizer, common mineral fertilizer and amino acids as foliar applications were tested.

Two field experiments were conducted at El-Horaia village, Abou El- Matamir district, El- Behira Governorate, Egypt, during 2014/2015 and 2015/2016 growing seasons, in split plot design with three replications.

The main plots included foliar application (mineral, amino acids, nano fertilizer, mineral + amino acids, mineral + nano- fertilizer, and amino acids + nanofertilizer), while three bread wheat cultivars (Sids 12, Sids 11 and Giza 168) were allocated in the sub plot.

The obtained results revealed such significant increases in plant height, spikes number/m2, spikelets number/spike, grains number/spike, 1000- kernel weight, grain, straw, and biological yields/fed., as well as harvest index (%) using nano- fertilizer + amino acids during both growing seasons.

Meanwhile, the applied mineral fertilizer, alone; gave the lowest mean values of the studied traits.

However, “Sids 12” cultivar recorded the highest means values of the studied characters.

Spray “Sids 12” cultivar by nano- fertilizer and amino acids; recorded the highest mean values of yield and its components.

On the other hand, “Giza 168” cultivar, possessed the lowest ones.
