The chisel plough is the most important soil preparation machinery for planting and its
direct effect on the physical properties of the soil is reflected in the cultivated yield.
The purpose of this research is to evaluate the performance of the lo
cal chisel plough
through its positive effects on the physical properties of soil so as to tillage heavy clay soil,
the most difficult types of soils, and then determine the time period for the disappearance
of these effects and the return of the soil as it was prior to tillage and planting in terms of
these physical properties. When planting the wheat crop under Syrian conditions.
The actual field capacity of the plough was (1.01 hec/h) and field efficiency (79.53%), and
consumed fuel (13.97 l/h).
There was a positive change in the physical properties of the soil due to the use of the
chisel plough and two perpendicular faces, where the bulk density of the soil decreased
(23.8%) and moisture content from (30.85%) to (28.33%). While increasing the total soil
porosity (13.26%) and air porosity (56.76% ) and void ratio (45.71%).
It was found that the positive effects of the chisel disappear during one agricultural season.
The process of tillage cannot be dispensed with the tillage to cultivate the wheat crop under
the Syrian conditions (the Algab area). It must be done the traditional tillage (two faces),
Where it was found that the soil return to its status before tillage and planting after (180)
days, before the end of the planting season and before harvesting the wheat crop by about a
month.
It was found that some of the physical properties of the soil contributed to determining the
time period for the return of the soil properties as they were prior to tillage. These include
the bulk density of the soil, the total porosity of the soil and the void ratio that are directly
affected by tillage.
Some of the physical properties did not contribute to determining the time period for the
return of soil properties as they were prior to tillage. They include both soil moisture
content and air porosity, which are affected by tillage, but are more affected by climatic
conditions such as temperature and rainfall.
The type of tillage methods is considered to be as an important
factor for seed bed preparation, consequently, this will be reflected
in the quantity and quality of production, different types of tillage
methods were used such as turning plough, s
tandard disk plough
etc, for Anise Pimpinella anisum seed bed preparation, the
experiment was conducted in the western area of Homs province.
The type of tillage methods is considered to be as an important
factor for seed bed preparation, consequently, this will be reflected
in the quantity and quality of production, in comparison to control
(minimum tillage) different types of tillage
methods were used such
as turning plough, standard disk plough etc, for Anise Pimpinella
anisum seed bed preparation, the experiment was conducted in the
western area of Homs province.

The experiment was conducted at the Agricultural Research Center in Salamiah in Hama province, in
clay loam soil in October 2010. Furat tractor with a single hung disk harrow was used as a machinery unit,
using three speeds. the seeding with drill
seeder was executed after Applying tillage one time for the systems
required one face, and twice for the systems required two, while a plot of land was left for" zero tillage"
system.

The reasearch was carried out during 2009 – 2010 in Al – Hasaka – Amoda - to study
the effect of cattle manure at the rat of 30 ton / ha , and four organic green manure ( Lentil,
Vetch, Faba bean and Barely) on soil content of organic matter and so
me mineral elements
compared with chemical fertilizer 400 kg / ha urea , 83 kg / ha P2O5 and 25 kg / ha K2O .
The manure significantly increased organic matter , phosphorus and potassium
concentrations compared with other fertilizers ( chemical and green fertilizers ) . All green
fertilizers ( Lentil , Vetch , Faba bean and Barely ) significantly increased organic matter ,
nitrogen and potassium concentration compared with the control without using any
fertilizer , the tillage depth ( 0 – 10 ) cm significantly increased soil content of organic
matter and nitrogen compared with deeper tillage ( 25 – 30 ) cm during the two seasons .
The research was carried out during 2009-2010 in agricultural seasons, in Alqusser area, western south of Homs city to study growth analysis of Spanish faba bean (var.alfa docle) under the effect of different ploughing methods on leaf weight ratio (L
WR) relative leaf growth rate (RLGR), leaf area ratio (LAR), leaf area duration (LAD), crop growth rate (GGR) and net assimilation rate (NAR), using four ploughing methods: surface tillage(T1), disk tillage (T2), place tillage (T3) and disk-turning (T4).the experiment was designed at randomized complete blocks, with five replications. The study showed the following:
The ploughing methods of disk Tillage (T2), Place tillage (T4), and disk- Surface Tillage (T1) had a Significant increase in leaf weight Ratio (LWR), Relative leaf growth Rate (RLGR), leaf Area Ratio (LAR, leaf Area Duration (LAD), Crop Growth Rate (GGR) and Net Assimilation Rate (NAR) during the Tow seasons.
Disk-turning (T4) had significant increase over disk-tillage (T2), and place tillage (T3) in all physiological indicators mentioned above (LWR, RLGR, LAR, LAD, GGR, and NAR). On another hand, there was no significant increase between ploughing methods disk-tillage and place tillage in all studies indicators.
The research was carried out during (2008-2009) and (2009-2010) in Fedio farm belonging to the Faculty of Agriculture to study the effect of various systems of tillage on the growth and productivity of Barley.
The results showed that the bulk densit
y increases with the first tillage system (control), comparing with the other tillage systems, but all of them were less than the control (no- tillage). The number of weeds increased when using the 6-th tillage system. The germination rate was affected by the tillage systems. The 6-th tillage system was the best. The weight of 1000 seeds and productivity increased by the 1-th tillage system (no-tillage) comparing with the other tillage systems. The number of weeds increased, but germination rate and weight of 1000 seeds decreased by using the 6-th tillage system. The yield of barley increased when using the 6-th tillage system. No-tillage system was the most economic compared with the others.
The experiment was carried out in Tartous Governorate in the Qubeiba region in the two agricultural seasons 2011 and 2012 to study the effect of different types of ploughs, the depth of plowing, and the timing of adding nitrogen fertilizer on some ph
ysical and chemical properties of the soil and some growth indicators of peanuts and its productivity. Three types of plows were used: MP ), disc plow ( DP ) and backhoe plow ( CP ) .
