Abstract

Tow field trials were carried out in 2011/2012 and 2012/2013
winter seasons to study the evaluation used the organic manure and biofertilizer as a total or partial replacement of nitrogen fertilizer on yield and
protein quality of two wheat varieties (
Triticum aestivum, L.) under newly
reclaimed soils. The field experiments were layout at the Experimental
Farm, of the Faculty of Agriculture, Fayoum University, Egypt. The
treatments were set in Randomized Complete Block Design in factorial
arrangement with three replications. The results showed that significant
effect for wheat varieties were obtained on plant height and spike length
in the 1
st season and total protein percentage in both seasons but were
insignificantly on other traits. The superiority was for Sakha 94 in most
characters. Fertilizer treatments were significantly effect for all studied
traits except plant height and number of tillers/plant in 2
nd season and
spike length in 1
st season. F3 (30 m3/fed organic manure + bio-fertilizer +
37.5kg N/fed (50 %) gave the superiority in most traits in both seasons
followed by F
4 (30 m3/fed organic manure + bio-fertilizer + 18.75kg
N/fed.(25%) or F
5 (30 m3/fed. organic manure + 37.5kg N/fed.(50
%)treatments. Interaction between varieties and fertilizer treatments was
significantly effect in most of studied traits except plant height and spike
length. On the other hand, applying of F
3 (30 m3/fed organic manure +
bio-fertilizer + 37.5kg N/fed.(50 %) with Sakha 94 or Sakha 93 gave
higher values of grains yield in both seasons. Finally, by using organic
fertilizer and/or bio-fertilizer with half dose of mineral fertilizer it could
be plant growth and yield. Besides, using bio-fertilizers that contain
different microbial strains had led to decrease in the use of chemical
fertilizers and had provided height products free of harmful agrochemicals
for human safety. In path coefficient analysis straw yield and spike length
revealed that positive direct effect and plant height through spike length
were positive indirect effect on yield. These traits can be considered for
selection.
