Research summary
تتناول هذه الدراسة تأثير معدلات ومواعيد رش السماد الحيوي على نمو وإنتاجية الفول السوداني في ظروف طرطوس. تم تنفيذ البحث في الموسم الزراعي لعام 2015 في قرية العريمة بمحافظة طرطوس، حيث تم دراسة تأثير ثلاثة مواعيد رش للسماد الحيوي (مرحلة الإزهار، مرحلة تشكل الثمار، ومرحلة تشكل البذور) وأربعة معدلات للسماد الحيوي (بدون رش، 2 سم³/ليتر، 4 سم³/ليتر، 6 سم³/ليتر) على نمو وإنتاجية الفول السوداني. أظهرت النتائج أن رش السماد الحيوي بمعدل 2 سم³/ليتر أدى إلى زيادة معنوية في جميع الصفات المدروسة باستثناء وزن 100 بذرة ونسبة التصافي. كما أن موعد الرش في مرحلتي الإزهار وتشكل الثمار أدى إلى زيادة معنوية في عناصر الغلة. تم الحصول على أعلى غلة ثمرية عند الرش بالسماد الحيوي بمعدل 2 سم³/ليتر في مرحلتي الإزهار وتشكل الثمار، حيث بلغت الغلة الثمرية 2970 كغ/ه و3500 كغ/ه على التوالي.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال تحسين إنتاجية الفول السوداني باستخدام الأسمدة الحيوية، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم التطرق بشكل كافٍ إلى تأثير السماد الحيوي على جودة التربة على المدى الطويل. ثانياً، كان من الممكن تضمين تحليل اقتصادي لتكلفة استخدام السماد الحيوي مقارنة بالأسمدة الكيميائية التقليدية. ثالثاً، لم يتم دراسة تأثير العوامل البيئية الأخرى مثل درجة الحرارة والرطوبة على فعالية السماد الحيوي. على الرغم من هذه النقاط، فإن الدراسة تقدم نتائج قيمة يمكن أن تساهم في تحسين ممارسات الزراعة المستدامة.

This research was conducted during 2014 season at Miaar Shaker
plains in Tartous region, to study the effect of applied drought stress for
24 days in 4 growth stages of peanut crop, i.e., 1. Brunching stage, 2.
Flower initialing stage, 3. Pod form
ation stage, 4. Seed formation stage,
beside of control (full irrigation by 12 days intervals). And effect of
these treatments on some growth attributes and yield to peanut
genotype (Sahel).
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 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 ) .
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
Effect of organic and bio fertilizers (Azotobacter and phosphate solubilizing
bacteria) on production of potatoes and some soil properties was studied in
Tartous.
The experiment consisted of 4 treatments (control soil, soil+manure, soil+
bioferti
lizer and soil+manure+biofertilizer) each replicated four time, for 2004
and 2005 seasons.
Total N, available P, available K, and organic matter in soil were
determined.
Significant increases were observed in most of the inoculated and organic
fertilized treatments compared with the control. However, the treatment
(soil+manure+biofertilizer) was the best and showed significant increases in
potato yield compared with other treatments especially in the next season.
However, the second season was better in yield increase in all treatments
than the first seacon.
