Research summary
تُعنى هذه الدراسة بتقييم تأثير تقليل مياه الري وتقليل كمية الأسمدة المعدنية على ملوحة التربة وبعض خصائص النمو وإنتاجية محصول القمح. أُجريت التجربة في العراق، محافظة واسط، مدينة النعمانية في عام 2021 على تربة طينية ذات ملوحة تزيد عن 4 ديسيمترات ودرجة حموضة 7. شملت التجربة عاملين رئيسيين: نظامي الري (الري السطحي والري بالرش) وأربعة مستويات من التسميد المعدني (200، 250، 350، 450 كجم/هكتار). أظهرت النتائج أن الري بالرش مع أعلى مستوى من التسميد (450 كجم/هكتار) كان له تأثير إيجابي على عدد حبات السنبلة ووزن 1000 حبة ووزن الحبوب لكل متر مربع ومؤشر الحصاد. تم تنفيذ التجربة بتصميم القطع المنشقة بثلاث مكررات، واشتملت الدراسة على ثماني معالجات في كل مكررة. أظهرت النتائج أن الري بالرش كان أكثر فعالية في تحسين خصائص النمو وإنتاجية القمح مقارنة بالري السطحي، خاصة عند استخدام أعلى مستوى من التسميد المعدني.
Critical review
دراسة نقدية: تقدم هذه الدراسة مساهمة مهمة في فهم تأثير تقليل مياه الري والتسميد المعدني على ملوحة التربة وإنتاجية القمح. ومع ذلك، يمكن تعزيز الدراسة من خلال تضمين تحليل أعمق للتأثيرات البيئية والاجتماعية لتقنيات الري والتسميد المستخدمة. كما أن الدراسة تفتقر إلى تحليل اقتصادي يوضح تكاليف وفوائد استخدام أنظمة الري المختلفة ومستويات التسميد. بالإضافة إلى ذلك، يمكن تحسين الدراسة من خلال إجراء تجارب إضافية في مناطق مختلفة وبظروف تربة متنوعة للتحقق من تعميم النتائج. وأخيرًا، يُفضل تضمين توصيات عملية للمزارعين بناءً على النتائج المستخلصة من الدراسة.

The purpose of this research is to apply a mathematical program to
calculate water and chemical balance in unsaturated soils, under the
influence of different methods of irrigation, in order to monitor the
amount of vertical drainage of water insi
de the soil and choose a
irrigation method that can reduce the phenomenon of groundwater
pollution.
Three irrigation methods were tested with different fertilization
method. The study was conducted in the western part of Homs
Governorate (AlQusair orchards).
A field experiment was carried out in Hout research station- Agriculture research center in
Swaida – General Commission For Scientific Research Agricultural during the growing
season of 2015-2016 to study the effect of different levels of deficit i
rrigation with
different levels of town refuse compost (TRC)on some morphological parameters and the
productivity of lettuce and compare it with the common mineral fertilizers.
The experiment was designed as a split block design with three levels of irrigation, each
level has four fertilizing treatments and control with three replicates.
The research has studied the plant height (H), the number of its leaves (N) ,the leaf area
(LAL), the plant's leaves area (LAP), the leaves area index (LAI), in addition to the lettuce
head's fresh weight and the total productivity of the planted area.
The irrigation and fertilizing interaction results indicate to the obvious positive effect of
the organic additions on the productivity parameters and the efficiency of deficit irrigation,
and the significant superiority of T11 treatment in all of the measured parameters in
compare with the other treatments with an increased final yield of %169 comparing with
T15 and % 428 comparing with T35.
The results also indicate to the possibility of saving %25 of the consumed amount of
irrigation water by using TRC instead of mineral fertilizer , and reveal that the organicmineral
combination achieved a better yield with percentages of ( 29- 44 – 53 )%
comparing with single mineral fertilizer in the three studied irrigation levels (T1-T2-T3)
respectively.
These results give the farmer a wide range of possibilities to choose what suits his
available productivity needs , and a clear idea about the expected yield according to the
chosen treatment.
This study was conducted at the Faculty of Agriculture, Damascus
University, during two seasons (2002-2003) to assess the effect of irrigation
methods (drip, sprinkler, furrow) of maize (Gota 82). The results showed
significant differences between
irrigation methods in grain and green weight
production (average of two seasons, for grain: 6.48 t/ha,6.065 t/ha, and 7.905
t/ha for drip, sprinkler and furrow irrigation respectively, and for green
weight 24.4t/ha, 22.04t/ha, and 25.75t/ha for drip, sprinkler and furrow
irrigation respectively).Concerning total water requirement, drip irrigation
method was the lowest one (average of two seasons, 4392.87m3/ha) followed by
sprinkler irrigation (5565m3/ha) compared with furrow irrigation
(9011.92m3/ha).
A column experiment was carried out under the conditions of the laboratory of colloids and clay minerals at the Faculty of Agricultural Engineering at the University of Aleppo, in order to know the effect caused by the magnetization of irrigation wat
er on the chemical properties of soils irrigated with water of different salinity. The experiment was carried out on the Kskeis soil, located east of Aleppo city, and it was irrigated with three types of water of different salinity (Furat - Rasm Al-Hamis - Mishrifat Al-Zakiya). With irrigated water, the irrigation process was carried out with ten irrigations. The results indicated that the magnetization of showing off water reached its value, reached its value, reached its value, reached its value when magnetized. dS.m-1) was 4.05, while at the non-magnetized (dS.m-1) 3.7, the values of the sorbent sodium rate SAR were affected by the accumulation of salts in the subsurface layer of the studied treatments included in the study. The values of the rate of sodium adsorption SAR were also affected by the accumulation of salts in the subsurface layer of the studied treatments included in the study, and the magnetization of water contributed to the reduction of SAR values. 1.57, while it reached 1.93 in the same treatment irrigated with non-magnetized water.
The research was conducted in order to study the effect of irrigation with sulfuric saline water on some major soil properties and maize production
The flood irrigation process was carried out with four treatments: Treatment of witness was irrigated
with fresh water, treatment No. (1) was irrigated with sulfuric saline water according to the standardized maize irrigation, and treatment No. (2) was also irrigated with salty sulfur water standardized for maize irrigation + 20% washing rate, and treatment No. (3) was irrigated with water Sulfur saline according to maize irrigation standard + 30% washing rate,The results of the study showed that there was a slight significant difference between the four treatments in terms of the apparent and real density, while there were clear significant differences between the treatments in terms of ESP%, EC and carbonates with depth, and this was the result of washing salts with the excess amount of irrigation water used for washing. The results also show that treatment No. (3) was the best of germination percentage and productivity, while treatment No. (1) achieved the lowest germination and productivity(Fresh maize cobs yield with wrappers) , as the readings were as follows: The percentage of germination in the witness was 95%, in treatment (1) 90%, and in treatment (2) 95% and in treatment (3) 97%, while the productivity was in the witness 32.4 tons / ha and in treatment (1) 30.25 tons / ha and in treatment (2) 33.6 tons / ha and in treatment (3) 39.037 tons / ha. This indicates that irrigation with sulfuric saline water according to (water ration for maize + 30% washing) achieved the best results, as the economic feasibility of using sulfuric saline water was achieved by obtaining good production, providing fresh water and preserving the major properties of the soil.
