Abstract:
A field experiment was conducted at the farm of the college of
Agriculture, Baghdad University during the two seasons of 2006 and 2007 on
cotton Gossypium Hirsutum L.. The objective of this study was investigated
to response of some cotton properties to tillage systems and fertilizers. A split
plot design under randomized complete block design with three replications
was used.
Tillage systems (moldboard plow, chisel plow and no-tillage) were
represent main plot treatments , fertilizers ( cow and chicken manure,
chemical fertilizer and no fertilizer) as sub plot. L.S.D (0.05) for comparing
the means of properties was used in this experiment. Leaf area, Plant height,
length of inters nodes, number of sympodia per plant, dry root weight and lint
yield were studied in this research. The experimental results showed the
following:
1- Tillage moldboard treatment was significant increased percentage of
leave area, plant height, and length of inter nodes, number of sympodia
per plant, dry root weight for the two seasons, also increased lint yield
percentage during seasons 2006 compared with other treatments.
2- Cow and chicken manure fertilizers treatments, increased in leaf area,
plant height, length inter nodes, number of sympodia dry root weight
and lint yield for the two seasons compared with other treatments.
3- The interaction between tillage moldboard and fertilizer include cow
treatment was significant increased all the properties were studies in this
research compared with other treatments.
