GROWTH AND NUTRIENT UPTAKE EFFICIENCY OF WHEAT FROM NONIONIC SURFACTANT AMENDED SOIL
A. Mohammad, A. Moheman and Seema
Abstract
The effects of Triton X-100 (a nonionic surfactant) on growth and nutrient
concentration in tissues of wheat plants were examined. While in smaller doses,
the Triton X-100 significantly stimulate the dry weights of plant biomass
(shoots and roots) and nutrient concentration in plant tissues (shoots and
roots), it becomes toxic to plants at higher doses. The nutrients affected by
Triton X-100 were mainly Na, K, Mn, and Fe in the shoots and Na, K, Ca, Cu, Mn,
and Fe in the roots. The effect on the level of Zn in both shoots and root by
Triton X-100 was insignificant. In shoots there was no effect of Triton X-100 on
the concentration of Ca in shoots. However, in roots, the concentration of Ca
decreases with the increase of surfactant level in soil.

Abstract
In 1992 two organic field trials were set up on loamy sand and a loess loam in
western Saxony, eastern Germany. In these long-term field trials questions of
field fodder and arable systems, crop rotations with leguminous field fodder,
wheat and maize, different organic fertilizer regimes and nutrient cycling were
analyzed regarding their effects on soil fertility, yield and quality of the
plant products. The main results and conclusions of the first nine years of
these organic field trials are introduced and summarized here. During the crop
rotation the Nmin levels follow a characteristic course from the highest levels
after ploughing in the leguminous field fodder and the lowest values before and
during the repeated cultivation of the field fodder. Leguminous field fodder
shows a reciprocal adaptation by higher production potentials in lower available
nitrogen systems and vice versa. This is true especially in arable systems with
mulched leguminous field fodder, where a high N input but low legume field
fodder efficiency and relatively low grain yields of the following wheat and
maize crops are obtained.

A.M. Karapetyan, H.S. Movsesyan, N.P. Ghazaryan, M.A. Sargsyan
Abstract
As a result of fight action against harmful insects in Lake Sevan coastal forest
plantations within the period of 2005-2006, Bacillus thuringiensis (BT)
bacterial insecticides were introduced into the soils. It was found that
bacterial insecticides BT-23, BTB and lepidocide, introduced into the soils do
not have any negative influence upon the urease activity of soils that have been
water-free within the last 30-35 and 40-50 years. All the above mentioned gives
great opportunities for application of bacterial insecticides in this region..

V.I. Ragimov
Abstract
Accumulation to nitrogen and phosphorus in cotton in the phase of budding is
connected with physiological peculiarities. This phase is a transition period to
form generative organs and requires great amount of nutrients. The reason of the
decrease of nitrogen and phosphorus content in cotton in the phase of forming
boxes in connected with the transition of nutrients from vegetative organs into
generative ones.

Yu. Z. Barseghyan
Abstract
Under the conditions of different formation systems, length of pruning of
fruit-bearing shoots and different loadings of grapevines the indices of sugars
and nitrogen combinations in the leaves of grapevine have been studied during
fruit formation and efficient growth of Mskhali, Saperavi and Hadisi grape
sorts. It has been revealed that the unilaterally combined formation system with
the mentioned indices in case of the tested three sorts exceeds the control
fan-shaped, free and multishoot system. Comparatively high contents of sugar as
well as nitrogen combinations contributed to the increase in crop yield,
increase in annual growth of grapevines and expansion of leaf surface except for
Hadisi sort.

PATHOGENESIS AND TREATMENT OF DERMATOMYCOSIS
R.G. Bostashvili, M.N. Chikaidze M.L. Zhgenti
Abstract
8 heads of young animals of cattle (at the age of 3–8 moths) and 2 stallions (at
the age of 5 and 7 months), sick with dermatomycosis and two persons (mother and
son) diseased with trichophytia, who contacted with sick animals have been
examined. The pathogenes – Tr.mentagrophytes, type-ectotrix have been determined
by the investigations of pathological materia, that was taken from sick animals.
We treated animals by worked out by us preparations UP and UPS rubbing the
oiniment three times into the damaged hearth, once in 3 days. Clinical symptoms
of recovering in animals were noted after the first use of both preparations
while after the second rubbing in of ointments the growth of hair was noted. The
full recover of animals occurred after 10–15 days. The preparations UP and UPS
are high by effective and economic preparations. The animals recover very soon.
The effectiveness of both preparations is100%.

V.I. Tvaliashvili, G.B. Antidze, T. Sh. Papuashvili, A.I. Ruadze, S. B. Chapidze
Abstract
Isolated wounds of auricular region are rearity in dogs, the most pathological
processes are passaged on a periauricular tissue too. As the auricular tissue is
rich in blood and lymphatic vessels and neurons, healing flows without
complications, but a special bandage and suture are necessary. In our practice,
as a matter of fact, hematoma is a common complicatione and we perform incision
or aspiration procedures.To prevent perichondritis we need special kind of
suture in combinacion with ointments, such as Vishnevski ointment or ikhtiolus.
Also, antiseptic solutiones are recomended but we never use antibiotices in
enteral or parenteral way. Sometimes we use vessel ligature to prevent more
irritation and hematoma formation.
ON OCCURENCE OF ACUTE FORM OF PARAMPHISTOMIDOSIS OF RUMINANT ANIMALS IN GEORGIA IN 2008
Sh.O. Potskhveria
Abstract
In Lanchkhuti district (the local source of Paramphistomidosis in West
Georgia), with dominant wet subtropical climate, the precipitations happened
more than standard in May-July, 2007 (69.2mm) and November-December, 2007, also
in January-April 2008 (364mm) and at the same time the monthly indicator of air
temperature in April 2008 was 15.1°C, which exceeded the stand and April norm by
2.7°C. According the Katcov’s formula, calculated the forecast coefficient of
Paramphistomidosis by the May, 2008 for Lanchkhuti district was 3.7. It meant
that in the second half of summer and at the beginning of autumn of 2008 in the
village of Lanchkhuti and near places the mass Paramphistomidosis of ruminant
animals in acute form occured. Accordingly, the local vets should conduct
unplanned prudential dehelmintization of young cattle. In Kvareli district (the
local source of Paramphistomidosis in East Georgia), with dominant dry
subtropical climate, in May, 2008 the forecast coefficient of Paramphistomidosis
was less than three (2.8). Therefore in the districts located by the river of
Alazani Valley the occurence of Paramphistomidosis of ruminant animals in acute
form is not expected..

Abstract
Toxigenic clostridia are widespread in external environment in human, animal's
organisms and sometimes in food. In a place of inhabitancy clostridia are found
in association with other species of microorganisms, so they exchange genetic
material and clostridia are turned out to be donors, in such a case for
escherichia; herewith different properties are transmitted: resistance to
antibiotics, toxigenity, hetopical activity, antigenicity. These properties are
determined in plasmids, transmitted with transformation, transduction and
conjugation. Toxigenic clostridia were isolated from soil, mineralized excretion
of animals, internals of slaughtered animals and pasteurized milk. Only
toxigenic cultures were chosen, which belonged to different species:
Cl.perfringens, Cl.chauvoei, Cl.oedematiens and Cl.septicum. After referring
them to species, they were used as donors when crossing them with nonpathogenic
escherichia for the transmission of either properties.

MILK PRODUCTIVITY OF THE CROSS-BRED EWES DEPENDING ON THEIR AGE AND MULTIFETATION
T.I. Paikidze, G.T. Begheluri, N.Sh. Bekauri
Abstract
The milk productivity of the 2 and 3 cross-breed ewes, according to their age
and the number of lamds has been studied. It has been determined that the
lactescence of 2 cross-bred ewes is increased before the 4 years of age, but in
3 cross-breed ewes – at 5 years of age. The minimum lactescence in both groups
is observed at the 2 years of age. The lacrescence of ewe with two lamds is
higher than ewe with a lamb, in both cross-breeds, in all age groups. The
lactescence of 3 cross-bred ewes always is higher than 2 cross-bred ees within
25–30%.
