Evaluation of wheat genotypes (Triticum aestivum L.) and some soil properties under saline water irrigation

2018-11-28 10:36:10 Keywords Nutrient uptake, soil properties, salt tolerance, Wheat genotypes, evaluation,
Evaluation of wheat genotypes (Triticum aestivum L.) and some soil properties under saline water irrigation
Sixteen genotypes of spring wheat (_Triticum aestivum_ L.) from different countries were evaluated for salt stress tolerance in the greenhouse under saline water irrigation. Five treatments, (T1) = tap water (control), (T2) = 25 mM NaCl, (T3) = 50 mM NaCl, (T4) =75 mM NaCl and (T5) = 100 mM NaCl were applied for each genotype grown in two seasons. ... Read more

INTELLIGENT ESTIMATION OF SPATIALLY DISTRIBUTED SOIL PROPERTIES

2018-10-31 08:51:20 Keywords spatial variability, soil properties, Remote sensing, GIS,
INTELLIGENT ESTIMATION OF SPATIALLY DISTRIBUTED SOIL PROPERTIES
The physical, chemical and biological properties of the soil are useful for evaluating its fertility, predicting the crop productivity (CIA, 2016). A SOIL HEALTH CARD (SHC) is issued in 2015 in India to a farmer he may enrich his soil for productivity and thus earn more benefits. For this purpose soil survey is carried out to record the crop limiting ... Read more

DIFFUSE REFLECTANCE SPECRTOSCOPY FOR ASSESSMENT OF SOIL PROPERTIES

2018-10-31 08:56:34 Keywords hyperspectral RS, soil properties, Remote sensing, GIS,
DIFFUSE REFLECTANCE SPECRTOSCOPY FOR ASSESSMENT OF SOIL PROPERTIES
uDiffuse Reflectance Spectroscopy (DRS) is important for Qualitative and quantitative assessment of physical and chemical soil properties. uThe accuracy of statistical approaches such PLSR predictions in each of the spectral regions varied considerably amongst soil properties. uA major advantage of DRS for soil analysis is that from a single spectrum many properties may be accurately determined. uBy the application of ...

opportunities and challenges of Egyptian soils

2018-10-28 17:50:48 Keywords soil properties, Reclaimed Soil, soil,
opportunities and challenges of Egyptian soils
Today’s agriculture faces many problems that are inherent to modern agro-technology whereas high productivity necessitates intensive fertilization and irrigation. Both of these inputs to ecosystems may cause severe imbalances (Mag, 2008). As soil problems prevail in Egypt, and as the Egyptian government has been implementing several projects for land reclamation over the last decades, protection of existing soils as well ...

تأثير طرق الرى بالرش والرى بالتنقيط وكذلك اضافة محسنات التربة على بعض خواص التربة بمزرعة الكوامل بسوها ج– رسالة الماجستير

2018-10-18 00:21:07 Keywords drip, Sprinkler, soil properties, irrigation, amendments, sandy soil,
تأثير طرق الرى بالرش والرى بالتنقيط وكذلك اضافة محسنات التربة على بعض خواص التربة بمزرعة الكوامل بسوها ج– رسالة الماجستير
SUMMARY AND CONCLUSION A newly reclaimed area in the sandy western desert border of the Nile Valley of about 150 feddans was taken to evaluate the effect of soil managements such as methods of irrigation (drip and sprinkler) and adding some of amendments. According to a study was carried out in 1999 to evaluate the soil salinity, it was found ... Read more

Five treatments, (T1) =tap water (control), (T2)= 25 mM NaCl, (T3)=50 mM NaCl, (T4)= 75 mM NaCl and (T5) =100 mM NaCl were applied for each genotype grown in two seasons. Soil properties were also evaluated ... Read more

Effect of Pressmud, as an Organic Fertilizer, on Some Soil Properties, Growth of Tomato Plant and Infestation of Tuta Absluta Under Saline Irrigation Water

2018-10-11 19:54:37 Keywords Organic, Tomato, irrigation water, soil properties, tuta absluta,
Effect of Pressmud, as an Organic Fertilizer, on Some Soil Properties, Growth of Tomato Plant and Infestation of Tuta Absluta Under Saline Irrigation Water
A filed experiment was carried out to study the effect of addition pressmud (PM) as organic wastes under saline irrigation water on some soil properties, _Tuta Absuluta_ Damage and plant growth. PM was applied at rates of 0, 5 and 10 ton/fed. The soil was cultivated with tomato (Genotype: Alissa) under salinity irrigation which applied having 0, 25 and 50 ... Read more

Improvement of Soil Properties, Growth of Cucumber and Protection against Fusarium Wilt by Piriformospora indica and Two Industrial Organic Wastes

2018-10-11 22:15:13 Keywords cucmber, organic wastes, fusarium wilt, soil properties,
Improvement of Soil Properties, Growth of Cucumber and Protection against Fusarium Wilt by Piriformospora indica and Two Industrial Organic Wastes
The current work was focused on characterizing bagasse ash (BA) and press mud (PM) as soil amendments and to study their effect in combination with the endophytic fungus Piriformospora indica on Fusarium wilt (FW) of cucumber caused by Fusarium oxysporum f. sp. cucumerinum (Fo). Whereas BA and PM improved almost all physico-chemical properties of the soil evaluated, seed treatment with ... Read more

Soil Properties as Affected by Different Land Management Practices in the Sohag Region, South Egypt

2018-09-28 20:33:38 Keywords land management, low quality water, soil properties, Sohag, Egypt,
Soil Properties as Affected by Different Land Management Practices in the Sohag Region, South Egypt
In Egypt, there is a growing need for information relating to soil condition, its current status, and thenature and direction of change in response to management pressures. This information are required by landmanagers, and regional, state and national agencies to inform modified management and land-use practices andinvestment to maintain and improve the soil resource. The aim of the present investigation ... Read more
