STUDY ON APPLICATION OF AGROSTEMIN PLANT GROWTH REGULATOR IN SERICULTURE
Z. Petkov
Abstract
Foliar application of Agrostemin, a commercial growth regulator at mulberry
plants is very effective to favor physiological processes in mulberry and
silkworm larva, which contribute to increase the economic efficiency of silkworm
commercial rearing. In all tested varieties application of Agrostemin led to
improvement of leaf yield per plant and significantly higher yields were
observed in No 24, No 59 and No 106 varieties, 5.52%, 10.65% and 6.19%,
respectively. The increasing in productivity per unit area was to the tune of
10.65 % over the control in No 59 variety. Besides this use of Agrostemin led to
significant improvement of cocoon yield per one box of silkworm and the
exceeding toward controls was statistically proved and varied from 0.47% in No
26 variety to 2.55% in No 3 variety. In all tested varieties application of
Agrostemin had improved utilization of dry matter from 1da mulberry plantation
for production of cocoons, silk shell and eggs and in almost all variants the
differences toward non-treated controls were statistically proved. The results
obtained testifies that the used per us concentration of Agrostemin and the
period of treatment were favorable for its administration to get the maximum
improvement of economic efficiency of silkworm commercial rearing characters.
These give us enough reason to recommend using of Agrostemin for increasing
effectiveness of commercial silkworm rearing in sericulture.

THE ACTION AND AFTER-EFFECT OF NATURAL ZEOLITES ON THE HARVEST OF GEORGIA
T.G.Andronikashvili, M.K.Gamisonia. L.G.Eprikashvili, E.V.Kurtanidze
Abstract
It is shown that trial bushes of grapes that undergo the influence of
application of finely divided zeolitecontaining rocks and relevant
organo-zeolite fertilizers into the soil demonstrate increase of yield comparing
to the control plants by one and a half or two times. Moreover, application of
zeolites influences improving of qualitative indices of grape juice. Therefore,
sugar content of grape increases from 11-23% depending on the grades of grapes.
Positive action of after-effect of analcimecontaining rocks and relevant
organo-zeolite fertilizers on the second year of experiment on yield is also
denoted.

STUDIES ON IONIC SURFACTANTS ASSISTED SOIL: GROWTH AND NUTRIENT UPTAKE EFFICIENCY OF WHEAT PLANTS
A. Mohammad, A. Moheman and Seema
Abstract
This study was conducted to investigate the effects of cetyltrimethylammonium
bromide (CTAB) and sodium dodecyl sulphate (SDS) on the growth, nutrients
uptake, and translocation in tissues of Triticum aestivum under field
conditions. The concentrations of nutrients (i.e. Na, K, Ca, Cu, Zn, Mn, and Fe)
in shoots and roots were determined. The results showed that the nutrients
concentrations in shoots were less affected with the increase in concentrations
of surfactant (0.1% aqueous CTAB or SDS) in soil as compared to roots.
Similarly, shoot growth seemed less affected than root growth. As compared to
cationic surfactant (CTAB), anionic surfactant (SDS) was found to be more toxic
to plant growth and nutrients utilization by plants.

BORON-MANGANESE INTERACTIONS ON THE AVAILABILITY OF EACH TO MAIZE CROP
M. Tariq*, Rafiullah* and Amanullah**
Abstract
A boron-manganese interaction on the growth performance and availability of
maize crop was studied in the glass house on the eroded soil of Swabi during,
2007. Boron-manganese was applied at the rate of 0, 0.5, 5.0 kg B ha-1 and 0,
20, 40 kg Mn ha-1 in the form of boric acid and manganese sulphate, respectively
along with basal fertilizers 120 N: 90 kg P2O5: 60 kg K2O in the form of urea,
di-ammonium phosphate and potassium sulphate, respectively. Crop variety ‘Jalal”
was sown in pots containing 10 kg of test soil and harvested after 28 days.
Results showed that the fresh and dry matter yield were considerably affected by
the application of B-Mn, but no interactions were observed significant among
these micronutrients with respect to their statistical analysis, but the
concentration and total uptake of B and Mn were found statistically significant
and suggested both micronutrients were dependent to one another. However, in the
present study applied Mn effect was apparent on the concentration as well as
total uptake of B, indicated Mn antagonizing the B absorption, because such
antagonism was associated to the significantly inverse correlations between
applied Mn and B in plants. Moreover, results suggest that applied Mn has an
ameliorative effect on excessive soil boron.

SOME PARAMETERS OF BLACK-MOTLEY BREED COWS EXTERIOR REARED UNDER MOUNTAIN CONDITIONS IN THE REPUBLIC ARMENIA
L.M. Minasyan
Abstract
The results show that parameters of all the measurements of Black-Motley breed
cows of Jrarat milk complex are increasing with age. The results of comparative
investigations have shown that the main measurements of cows of Jrarat complex
concede a little to the measurements of cows of the same breed registered in the
80-th volume of State Breed Book of Russian Federation. Thus we consider that it
is more preferable to have milk-meat cattle of exterior-constitutional type such
as black-motley breed for a mountain zone of the republic using mountain
pastures, and in pasture conditions - cows of dairy type.
OBTAINING THE ANTIPASTEURELLOSIS HYPERIMMUNE SERUME
S.L. Grigoryan, S.G. Yeghoyan, M.H. Hovhannisyan
Abstract
Septicemic pasteurellosis of cattle, commonly associated with infection by
Pasteurella multocida, is the classical disease of southern Armenia
characterized by a peracute septicemia and high mortality rate. The disease
occurs most commonly in young growing cattle, and all age groups are
susceptible. An experiment has been made from subcutaneous hyperimmunization of
cows inactivaited by temperature of living cultures of pasteurell. The studies
have revealed that hyperimmunized cows developed high serum antibody titers to
the somatic antigens of the homologus organism. The challenge in the development
of an efficacious hyperimmune serume against pneumonic pasteurellosis is to
determine the specific treatment and protective antigen in the organism..
P. Tzenov*, D.Grekov**
Abstract
The study has been carried out at Sericulture Experiment Station(SES), Vratza,
Bulgaria and at Agriculture University in Plovdiv, Bulgaria. 15 silkworm breeds
of the Japanese type, 13 breeds of the Chinese type and 16 F 1 hybrids among
some of the breeds were used in the study. All the breeds/hybrids had white
cocoon color and were uni and bivoltine. All the breeds and some of their
hybrids were tested regarding to their tolerance to adverse rearing conditions
during the 4th and 5th instars (t 28-31 0 C, RH 75-80%, feeding amount and
rearing space – reduced by 50 %, very reduced ventilation). The results obtained
indicated that there was a genetically determined tolerance of some silkworm
breeds tested to rearing of the larvae under adverse conditions during the last
two instars. Two new four-way hybrids, namely (KKxHesa 1) x (Vesletz 2xGergana
2), (KK x AS ) x (Vesletz 2xGergana 2) and the reciprocal crosses, manifested
the highest tolerance to adverse rearing conditions together with a satisfactory
high productivity under optimal rearing were created. It has been proved through
this study that the method by using selected for tolerance to adverse rearing
condition silkworm breeds could be used successfully to create comparatively
tolerant to adverse rearing conditions silkworm bivoltine commercial hybrids,
having moderate productivity.

N.K.Baramidze, M. V. Khutsishvili, Sh.G. Kharatishvili
Abstract
Due to the effect of bio-stimulator Asma No1, mulberry silkworm cocoon and
membrane mass, silk capacity and viability of silkworm are increased. 0.1%
concentration solution of the bio-stimulator proved to be the most efficient.
Likewise efficient is 0.1% bio-stimulator concentration with respect to the
increase of silkworm and silk gland masses. With the view of accumulation of
protein in hemolymph the 0.1% bio-stimulator concentration yielded the best
results.

T.I. Paikidze, G.T. Begheluri, N.Sh. Bekauri , E.P.Titvinidze, Ts.D. Khoshtaria
Abstract
The facts, given in this article, have confirmed the relations between feeding
and milk productivity of 2 and 3 cross-breed ewes depending on the seasons,
fatness and physiological conditions (fetation period, lactation). These
investigations determined definite interrelation between feeding and milk
productivity of sheep of different genetic origin. These investigations confirm
maximum productivity of ewes providing full supply of feel for lambs. The
results of the experiments have shown that 3cross-bred ewe's lactescence is more
than 2cross-bred ewes.In the 3cross-bred ewes (I, II and III subgroups) the
lactescence was 61.40; 50.75 and 69.15 kg, but in 2cross-bred ewes – 46.35;
36.35 and 59.78 kg.

Abstract
For study the blood parameters, the blood of different age groups _ fingerlings
(1-year old) and commercial size (3-year old) Salmons were collected and
compared from Shaheed Bahonar Hatchery Center. The numbers of Red Blood Cells
(RBC), White Blood Cells (WBC) and hemoglobin in 3-year old Salmon were found to
be less than that of 1-year old Salmon and the former had more Mean Corpuscular
Volume (MCV) than the latter. Other parameters have shown no difference. It was
shown that the most suitable age for releasing different age groups of Caspian
Salmon from the hatchery into the river the is that of the fingerlings, due to
better adaptation ability in wild conditions in the river.

R.A. Grigoryan
Abstract
Having more than fifty years of research-predictive experience in the forest
sector we came to the conclusion that it is also necessary to apply combined
system cuttings in the complicated and diverse-aged forests, thus all types of
fallings can be carried out in unity forest plots which will exclude the
destruction of under grown stands and privet and full damage to standing trees
cut to root.
FORESTRY REFORMS IN GEORGIA: ECONOMY, JUSTICE AND PROCEDURAL ASPECTS
T.E. Kandelaki
Abstract
The process of the forestry reforms in the Georgia is discussed. Along with
positive aspects the advanced consequences of the reforms in the sector of
forest farming are evaluated and criticized. The bases of the sector of forestry
are economy, justice and procedural aspects which cover the whole sphere, should
have the systemic character. It is stated that the institutional structure of
resource management is less effective and it does not insure the sustainable use
and development of forests. Without forest management and other state programs,
it is not advisable to rent forests for long terms for the reason of getting
timber resources.
