A field experiment was conducted for two years 2011-2012 to evaluate the effect of various tillage implements, tillage depths and nitrogen fertilizer timing application on soil bulk density, its moisture, and peanut growth. Three different implements
were used: moldboard (MP), chisel (CP) and disk ploughs (DP). Tillage depth treatments (split-plots) included (8-10) cm, (18- 20) cm and (28- 30) cm tillage depths; D1, D2 ,D3 respectively. Timing applications (split-split- plots) were: T1 all nitrogen fertilizer applied at planting ,T2 half nitrogen applied at planting and half at flowering ,T3 all nitrogen fertilizer applied at flowering.
All tillage implements decreased soil bulk density for the tillage depth. They were for treatments (DP,CP,MP) at (0-10)cm depth (1.31,1.33,1.29) g/cm3, (1.31,1.32,1.31) g/cm3 at (10-20) cm depth and (1.36,1.37,1.35)g/cm3at(20-30) cm depth. Soil moisture increased in treatments (DP,CP) with increasing tillage depth .There was no effect of previous factors on main branches, but timing of nitrogen fertilizers (T1, T2) effected secondary branches significantly compared to T3. Moldboard significantly increased leaf area to (1.77) m2/plant compared to chisel (CP) and disk ploughs (DP). Also D2, D3 increased leaf area compared to D1. (T1, T2) significantly increased leaf area compared to T1. Interaction between timing of application and depth (D3 xT2) gave significant differences. The best value was (1.85) m2/plant for the two years.
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 2009 – 2010 in Al – Hasaka – Amoda – to study the effect of cattle manure at the rate of 30 ton/h1, and four organic green fertilizers (Lentil, Vetch, Faba bean and Barely) on plant area and earliness properties of
cotton crop compared with chemical fertilizer 400 kg/h1 urea, 83 kg/h1 P2O5 and 25 kg/h1 K2O.The study showed that the cattle manure significantly increased (plant area, lower first fruiting branch, earliness of flowering and boll maturity) when compared with all studied fertilizers, the increase reached (190. 92 Cm2, 0.30 pod, 1.50 day and 0.90 day) respectively. When compared with chemical fertilizer, the legume green fertilizers (Lentil, Vetch and Faba bean) significantly increased the plant area when compared with the control. The legume green fertilizer (Lentil) significantly increased the earliness of flowering (2.73) day and boll maturity (2.21) day when compared with the green fertilizer (Barely). The chemical fertilizer did not significantly affect the earliness of flowering and boll maturity when compared with the legume green fertilizer (Lentil) during the two seasons.
A field experiment was conducted in Agriculture collage –Tishreen University for two years 2011&2012 to evaluate the effect of tillage depths and nitrogen fertilizer timing application on growth productivity indicators and seeds' chemical compositi
on of peanut plant. The experiment was designed in split plots with three replicates. The main plots included shallow tillage (8-10) cm, medium tillage (18- 20) cm and deep tillage (28- 30) cm tillage depths D1, D2, D3 respectively. Timing application (split- plots) were: T1 all nitrogen fertilizer applied at planting ,T2 half nitrogen applied at planting and half at flowering ,T3 all nitrogen fertilizer applied at flowering .Deep tillage caused significant differences and increased leaf area index to (11.93,11.80) for the two seasons respectively . For dry weight/plant were (285.9, 266.6) g for two seasons respectively and seeds index arrived highest values (74.32, 74.53) g for two seasons respectively. Tillage depth increased protein and oil percentage in seeds, but the effect was insignificant. Timing of nitrogen fertilizer had significant effect on leaf area index. The best values were (11.80, 11.60) for two seasons respectively in the treatment T2, and dry weight/plant (283.0, 263.4) g/plant respectively. Significant effect was observed for seeds index. The highest values were (74.41, 74.21) g for two seasons respectively in the treatment T2, so that for protein percentage in seeds arrived highest values (24.35, 25.24) % respectively in the treatment T2. But the highest values of oil percentage were (47.10, 47.21) % for two seasons respectively in the treatmentT3. Interaction (D x T) had significant effect on leaf area index. The best values were (12.53, 12.07) for two season respectively at (D3 x T2) interaction treatments. This interaction had no significant effects on the rest of the indicators

The research was Carried out in Jisr area in the province of Idlib during the growing
season 2013 - 2014 to study the effect of planting dates in autumn sowing 28/9/2013 = (1),
8/10/2013 = (2), 18/10/2013 = (3) and spring sowing 18/3/2014 = (1), 28
/3/2014 = (2),
8/4/2014 = (3) on yield and growth parameters.
The results showed that the autumn sowing has a significant increase in growth
parameters compared to spring sowing: adapting coefficient (76.67-82.28%), Plant hight
(67.15 - 56.3 cm), number of branches/plant (11.63 - 6.84), number of head/Plant (21.39 -
17.76), oil content (23.19 - 20.68)%, yield petals (96.12 - 60.57) kg/ha, seed yield (1331.82
- 768.31) kg/ha, oil yields (315.15 - 158.99) kg/ha to autumn and spring, respectively.
While maturity date of autumn plants was delayed compared to spring (245.33 - 145.33)
Day.
When sowing was of autumn, growth parameters of third soing date were a
significantly higher compared to both the second and first sowing: number of branches /
plant, number of heads / plant, number of seeds / head, oil ratio (%), oil yield (kg/ha),
yields seeds ( kg/ha), petals yield (kg/ha). Wheras the first sowing date has delayed
maturity date compared of both the second and third sowing dates.
When sowing was in spring, growth parameters of the first sowing dates were a
significantly higher compared to both the second and third except for days to maturity.
The lack of information about the cultivation of coriander plant in Syria prompted us
to study the effect of four plant densities (33.33،10، 13.33 and 20 plant/m2)، and four levels
of phosphate fertilization (0107.2،160.8، and 214.4 of Superphospha
te 46%) on some
productive and quality traits of the coriander plant. This study was carried out in Tartous
province during the growing season 2014، using Randomized Complete Block design with
a Split Plot arrangement of treatments. The Results revealed that there were significant
differences between the treatments for the whole traits، in addition to a significant
interaction between density and phosphate fertilization. Although the densities (10، 13.33
and 20 plant/m2) varied in their effect، they had superiority upon the
control(33،33)plant/m2، and the density 10 plant/m2 had more important effect in terms of
increasing each of: branches number/plant، seed weight/plant، seeds number/inflorescence،
protein content in plants and seeds and beta carotene and chlorophyll. However، the level
160.8k.g/h of P2O5 increased the number of inflorescences/plant، number of fruits/plant
and seed weight/ inflorescence.
Seven cotton varieties (Rakka 5, Aleppo133, Aleppo 90, Aleppo 118, Aleppo 40,
Deir 22, and Line124) were used in the study of some quantitative characteristics of cotton
yield and its components (seed cotton weight per boll/g, 100seed/g weight aver
age, lint
percentage %, seed cotton weight per plant/g, total dry matter weight, seed cotton yield per
unit area kg/ha), and physiological qualities (leaf area cm2, leaf area index %). The seven
varieties were grown in Salhab (Al-Ghab region, Hama) in 2012 using randomized
complete block design with three replications.
The study included estimating variance, broad sense heritability, genetic progress,
and genetic correlation between cotton yield and its components, which is to be used in
breeding programs.
The research was carried out during 2011-2012 in order to study the effects of five
levels of fertilization (mineral fertilization N:65 P:65 K:70kg/h, and organic fertilization 5,
10 and 15ton/h), three spaces between rows (50, 75, and 100cm), one
15cm space between
one plant and another, and the interaction between them on the production of safflower dry
colored leavel, seed, and oil.
The study showed the following results: all the levels of the studied fertilization were
significantly superior in the production of dry colored leavel, seed and oil over the control.
However, there were no positive differences in the proportion of oil between the treatments
of fertilization and the control.
The 100cm farming space among rows led to a significant positive effect in the
production of safflower seeds, while the 50cm distance among farming rows in the
production of dry coloring leaves was superior over 100cm and 75cm distance. There were
no positive differences in the proportion of oil; while the mean of oil productivity came
down whenever the plant spacing increased from 50 to 75 and then 100cm.
The interaction between the levels of the studied fertilization and agricultural plant
spaces gave a positive significant effect in most studied characteristics. The most
significant positive effect was for the interaction between the mineral fertilization and
100cm distance, and then came the average of the organic fertilization 15ton/h and 100cm
space between rows.
