RESEARCH PROJECTs Rural integrated development of the mountains of the northern region of Lebanon This project was initiated in agreement with Food and
Agriculture Organization of the United Nations (FAO) and the Ministry of
Agriculture to study, classify, and make soil fertility recommendations for
all crops in Zawia/ Zgharta region. The project is in progress. Bashour, I. Supported by Food and Agriculture Organization of the
United Nations Selenium levels in Lebanese agricultural soils This study was conducted to evaluate the status of
selenium in Lebanese agricultural soils and selected forages since no such
studies were done earlier. Soil samples were collected from the Bekaa, Mount
Lebanon, north and south districts representing the majority of agricultural
Lebanese soils. Alfalfa and corn plants were collected when available from
the same sampling sites. Soil physical and chemical properties ,water-soluble
Se and AB-DTPA extractable Se were determined in the collected samples.
Results showed that all soil samples contained low levels of extractable Se.
However, Se content of the alfalfa and corn samples was within acceptable
range. The most important factor that determines Se content in plant tissue
is plant variety and some favorable conditions that facilitated Se absorbance
from the soil, such as basic soil pH and presence of CaCO3. To prevent the
possibility of Se deficiency in animals, moderate supplementation of Se is
recommended. Bashour, I. Supported by URB Analysis of DDT in soils by gas chromatography and immunoassay methods The use of (ELISA) method in estimating DDT pesticide
residue in soils is a faster, less expensive and an easier method to use than
gas chromatography (GC). Soil samples from Lebanon were analyzed for total
DDT residue using & ELISA methods. The results indicated that the two
methods were highly correlated. Differences in soil properties did not affect
the accuracy of the detection limits of ELISA; therefore, this method can be
used for rapid and accurate measurement of total DDT residue in mineral soils
in Lebanon. Bashour, I., S. Dagher, and N. Kawar. Supported by URB Evaluation of synthetic polymer (dp34) on crops The project was intended to assess the effect of a
synthetic polymer on the clogging of different emitter used in irrigation and
on the yield of vegetables and fruit trees. The research was conducted both
at the Agricultural Research and Education Center (AREC) and at private farms
in Shuwiifet and Kfarzabian. Research was conducted on strawberries using a
Bi-Wall drip lines, on beans using a point source pressure compensating
emitters, and on apples utilizing pressure compensating emitters. The
duration of the project was two years. Nimah, M. (PL). Supported by Feed Water Company, London, U.K. Measurement of transpiration and evaporation under field conditions Agricultural productivity and sustainability are among the
most challenging issues facing the world today. With increased population
growth, water and land are becoming the limiting factors and food demand is
being urgent. In order to meet the imposed challenges, optimal use of these
scare resources should be considered. The objectives of this research are
first, to determine evapotranspiration of crops under different water
regimes; second, to measure transpiration and calculate evapotranspiration of
crops; third, to model crop production as a function of transpiration in
order to overcome site specificity; and fourth, to study the impact of using
vertical space on production in order to develop urban agriculture. To
achieve the above-mentioned objectives, an experiment was designed utilizing
vertical columns of soil that were subjected to two irrigation regimes and different
population density. Part of the columns were closed at both ends while the
others were opened at one end. Drip irrigation was used in this experiment.
Nimah, M. Supported by URB Olive yield as affected by supplemental irrigation and
split fertilization Olive crop grows on marginal lands in Lebanon, contributes to soil conservation, is adaptable and resistant and produces yields under the most adverse conditions. Although its production is on bi-annual basis it is considered the subsistence base of large population groups in Lebanon and has significant social and economic importance on the national level. In other olive producing countries, especially countries of the Mediterranean, it has been proven that if properly treated like other orchard crops, i.e., watered, fertilized, and properly managed, it can produce more on the same soils and yield a good profit in relation to cost involved. Currently, the average yield in Lebanon is about 6 kg/tree, which is considered a very low average compared to international yield. In Lebanon, only little research work, mostly sporadic, has been done so far to improve the yield of this important crop and the enhancement of its economic return, the repercussions of which were reflected sometimes in the neglect of the olive groves due to its uneconomical returns, and in other instances to the migration of farmers to urban centers in pursuit of new economic opportunities.
Supported by URB Improvement of the yield, quality and marketability Although the olive tree can grow on marginal lands, it has
been proven in many of the olive-growing countries of the Mediterranean basin
that, if properly cared for, watered, fertilized, and properly managed (e.g.,
implementation of proper agricultural practices), it can produce more on the
same soils and yield a good profit in relation to cost involved.
Currently, the average yield per tree in Lebanon is about 6 kg, which is
considered a very low average compared to international values. Developing Cd, Cr and Ni phytoremediation technology Screening and evaluation of local plants for the cleanup
