Abstract

On-farm field experiments were conducted to assess the effects of
planting methods (raised bed and farmer practices) on yield and macro
nutrients uptake of bread wheat, as well as amount of applied water. The
locations of the experiments were in ten farmers' field representing ten
districts at Al- Sharkia Governorate, Egypt, durinig 2011/2012 and
2012/2013 seasons.
The obtained results could be summarized as follows:
1-Sowing wheat on raised bed was superior in its productivity
compared with farmer practices (traditional sowing) at all locations
under study in both seasons. The relative increase of wheat
productivity for raised bed were 23.21, 24.70 and 23.98% for grain,
straw and biological yield, respectively in the 1
st season, as well as
34.63, 32.99 and 33.78% for grain, straw and biological yield, in
the 2
nd season, respectively.
2-Raised bed treatment gave the highest values of nitrogen,
phosphorus and potassium uptake for grain, straw and biological
wheat yield compared to farmer practices in both seasons. The
relative increase of N uptake for wheat grown on raised bed were
38.85, 52.22 and 41.41% in the 1
st season, as well as 49.28, 50.99
and 41.19 % in the 2
nd season for grain, straw and biological yield,
respectively. The relative increase of phosphorus uptake for wheat
grown on raised bed were 24.23, 24.90 and 24.48 % in the 1
st
season and 34.41, 39.53 and 36.39 % in the 2nd season for grain,
straw and biological yield, respectively in the 2
nd season. The
relative increase of K uptake for wheat grown on raised bed was
59.00, 47.87 and 50.08 % in the 1
st season, as well as 36.53, 40.59
and 39.82% in the 2
nd season for grain, straw and biological yield,
respectively.
3-Raised bed treatment gave the higher saving in irrigation water
more than the farmer practices treatment in both seasons. The
applied water for wheat sowing on raised bed was lower than flat
treatment by 1356 and 1212 m
3 ha-1 with savings of irrigation water
by 24.1 and 23.7% in the first and second season, respectively.
