Abstract

The present work was conducted at the Experimental
Farm of Nubaria that located 46 km west of Alexandria
during the two winter seasons (2015/ 2016 and
2016/2017). The main objective of the present study
was to determine the effect of nitrogen fertilizer levels,
biofertilizers and their interactions on growth and yield
of Shandaweel 1 (bread wheat cultivar) using split- plot
design with four replicates. The most important
obtained results could be summarized as follows:
Nitrogen fertilization at 90 kg/ fed produced
the highest number of spikes/ m2 (387.32, 402.13),
number of grains/ spike (58.17, 56.49), 1000-grain
weight (53.14, 54.22 g), grain yield (2.81, 2.43 t/ fed.),
biological yield (9.94, 7.58 t/ fed.) and protein content
(13.83, 12.85%) in the first and second seasons,
respectively, and harvest index (32.05%) in the second
season. Also, the same level of nitrogen produced the
highest LAI (6.149, 7.455) tallest plants (110.39,
112.09 cm), longest spikes (11.37, 10.73 cm) and latest
heading (95.08, 95.97 day) in the two successive
seasons.
Biofertilizers, especially Azotein significantly
increased all growth traits, number of grains/ spike,
1000- grain weight, grain and biological yields, harvest
index and protein content in the two seasons.
Biofertilizers combined with 90 kgN/ fed application
produced the highest LAI in the two seasons, grain and
biological yields in the first season and protein content
in the second season.
