This research was carried out during both growing seasons 2009/10 -
2010/11 at the National Center for Agricultural Research and Extension
(NCARE) / Karak Governorate / Jordan, to study the response of five barley
varieties namely Mu'tah, Yarmok,
Athroh, Rum and Acsad-176 to the effect of
four seeding rates (50, 100, 150 and 200kg/ha) and five nitrogen fertilizer levels
(0, 15, 30, 45 and 60kg/ha) on the productivity of grain and straw, the harvest
index and some phenological indicators.
Methodsof soils cultivating and organic fertilizer are considered as
the most important operations that change the soil; and prepare it
to receive multiplications units of the crops that we want to plant
and to provide the suitable conditions for feeding the plant later,
and to increase the production and to improve the quality along
with keeping the various properties of the agriculture soil.
The research was carried out in the fields of Akar plain in Tartous
province during two seasons (2013, 2014) to study the effect the three
multiplication methods (Slips as control, Seedling, Cut-seed tuber) on
growth and yield of two locally sprea
d sweet potato varieties. The
experimental design was a randomized complete block with three
replications. Data were analyzed using the statistical program GenStat 12.
