Response of some wheat genotypes to nitrogen application and biofertilizer in two different locations [electronic resource].

Includes reference

Four field experiments were carried out during the two successive growing seasons (2011/2012 and 2012/2013) at Etay El-Baroud Farm, El-Beheira Governorate and El- Hammam Farm, Marsa Matrouh Governorate, to study the effect of Nitrogen fertilization treatments on some growth, yield and yield components of fifteen bread wheat genotypes. The study included four nitrogen fertilization treatments (75 kgN/fed, 45 kgN/fed + Microbein, 40 kgN/fed and Microbein). The obtained results could be summarized as follow: 1- The highest nitrogen level (75 kg N/fed) significantly increased all studied characters for the fifteen bread wheat genotypes, however inoculation by Microbein only decreased all characters values in the two seasons at both locations. 2- The results showed that sids 12 cultivar often the earliest heading and maturity in the two seasons in both locations. Generally, Misr 2 cultivar had the tallest plants, however, Gemmeiza 11, had the tallest spikes in the two locations. Misr 1 and Giza 168 cultivars produced the highest grain yield at Etay-Baroud in the first and second seasons, respectively, and Gemmeiza 9 in the two seasons, while sids 13 gave the highest grain yield at El-Hammam in the two seasons. Sakha 94 had the highest number of kernels/ spike in the two seasons at both locations, sids 13 cultivar had the heaviest grains at EL-Hammam and Gemmeiza 9 at Etay El-Baroud, while line 2 produced the highest number of spikes/ m2 in the two seasons at Etay El-Baroud and Giza 168 at El-Hammam. The highest harvest index values resulted from Gemmeiza 9 and Giza 168 at Etay El-Baroud in the two successive seasons and Sakha 94 at EL-Hammam in the two seasons.
