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.

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.

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.
