CHLOROPHILL INDICES AND THEIR CONNECTION WITH WINTER BARLEY PRODUCTIVITY
Abstract:
It was investigated the preparations influence of steroid glycosides Eoldstim and Ecostim on the maintenance of plastid pigments (chlorophyll a and b, and carotenoids) in plants' organs of winter barley during the vegetation. The treatment of vegetating plants in the fraternity phase with preparations solutions leads to the concentration increase of plastid pigments and to their accumulation in photosynthesizing organs, and also to the parameters growth of chlorophyll indices. It was estab¬lished that the action of growth regulators depends on high-quality features of plants and on the kind of the predecessor. The maintenance of chlorophyll can be used as a parameter defining the potential biological efficiency of winter barley crops.

DYNAMICS OF HUMUS CONTENT IN THE SOIL UNDER THE INFLUENCE OF DIFFERENT FERTILIZATION SYSTEMS USED FOR A LONG PERIOD OF TIME
Abstract:
The leading index of ground fertility - the humus, is found in close-fitting depending on the applied fertilization systems in the crop rotation. Crop fields where the fertilizers haven't been used for a long period of time (more than 50 years) show a reduction of the humus content of about 0,30¬0,50% from its initial content in the layer of ground of 0-60 hm. The use of mineral fertilizers also reduces the small humus content in the ground. While the use of organic and organic-mineral fertilizers enlarges the humus content with about 0,25-0,30% compared with its initial content.

Abstract:
The analysis of the changes in the structure and function of microbial association as a part of ecobiocenosis was done from the point of view of the consequences of many years pesticides application in Moldova's agriculture. The estimation of ecological hazard of the studied herbicides has been done and on this basis was made an important conclusion: the application of sim-triazines and glean in Moldova's agriculture is unsuitable. The need to limit the application of aryloxyphenoxypropionate herbicides in Moldova was formulated.

THE INFLUENCE OF FOLIAGE FERTILIZATION ON APPLE TREES GROWTH AND PRODUCTIVITY
Abstract:
This paper presents the results of foliage fertilization with N in a plantation of apple trees placed in „Alfa-Nistru" JSC. As a biological material served two apple varieties: Pinova and Gala Must with Slender Spindle trimmed crown grafted on M9, planted on a distance of 3,5 x 1,2 m (2380 trees/ha). Our aim in these studies was to establish the optimum formula of foliage fertilization with N which favorably influenced some physiological processes of apple trees.
The obtained results showed that during 2005-2007 the yield increased significantly with 29 % at Gala Must and with 28 % at Pinova variety, applying the foliage fertilization in a concentration of 1,2 % N. The productivity of Pinova and Gala Must variety respectively was 43,8 t/ha and 47,0 t/ha.

The obtained results showed that the biological efficiency of the fungicides which contain copper (Champ WP and Kocide 2000 WP) against Phyllosticta was relatively low. A biological efficiency as in the standards was established in the experiments with fungicides which contain difenoconasol (Raeoc EC and Taspa 500 EC) and a higher biological effi¬ciency was obtained in the experiments with Tuoreg 500 WP (fungicide from the group of strobilurines).

RESEARCHES CONCERNING THE INFLUENCE OF GREEN PRUNING OF APRICOT TREES ON THE FRUIT LOAD AND BUDS DIFFERENTIATION
Abstract:
The apricot tree represents an early tree variety, that's why its buds may be affected by late spring frosts.
Green pruning relies on the feature of this variety, the one of having two or three growth periods.
Regarding those mentioned above, we have carried out some researches upon the behavior of some apricot trees with different ripening epochs, submitted to green prunings at different moments.
According to the the achieved results, we could conclude that successively to green prunings carried out in the apricot trees at different moments, we were able to notice a much bigger number of fruit buds and also the fruit load has been amplified.

THE FACTORS WHICH INFLUENCE THE SECURITY INDICES OF DISTRIBUTION SYSTEMS
Abstract:
The electrical power distribution systems (EPDS) possess a great dynamics of devel¬opment. Thanks to this phenomenon in the electrical power distribution systems (EPDS) the probabil¬ity of asymmetrical regimes apparatus increases monotonously. As a result of this reliability the functioning of the electrical power equipment installed in the electrical knots changes. The asymmetri¬cal regimes in the electrical power distribution systems accompanied by the short circuit current rep¬resent a function of a determinate row and it is a vague factor of probabilistic nature.
As a result it can be argued that the investigation of the influence of the asymmetrical regimes accompanied by short circuit current on the reliability of the Electrical Power Distribution Systems is one of the most important problems of the EPDS development.
The short circuit currents influence the structural and functional reliability of distribution networks and the reliability of electrical equipment installation.
Key words:
Asymmetrical regimes, Electrical power distribution systems, Reliability of electrotechnical equipment, Short circuit current.

REACTIVITY OF ARTERIAL VASCULAR BED IN SEPTIC AFFECTIONS OF CATTLE FINGERS
Abstract:
The researches have been performed using classical macro-preparations vessels, under the control of a binocular magnifier. At a macro-microscopic level, vessels preparations have been done after coloring total preparations by the reagent Shiff. The histological preparations occurring from soft fabrics of fingers of large horned livestock were painted by hematoxilin-eosin. We estab¬lished that a blood channel of soft fabrics of fingers, under the influence of pathological processes occurring in this area looses the muscular tone and arises on the sharp walls of a vessel. Their histological structure also varies from the architectonic arteries of various caliber. The infringement of arterial blood integrity conducts a channel to an aggravation of lameness, a decrease or to efficiency of animals full loss. During the treatment of septic affections of acropodial region at large horned livestock, the vascular factor will be also taken into consideration, rendering its appropriate protection.

THE EVOLUTION OF AGRICUTURAL LAND FUND IN ROMANIA AND ITS VULNERABILITY TO DIFFERENT DEGRADATION TYPES
Abstract:
The efficiency of different antibacterial substances in small animals practice became a very important element in veterinary pharmacotherapeutics.
Dogs' kidney diseases, taking into account their incidence and severity, are situated in front of the list. Inflammatory diseases at dogs have a complex etiology (sometimes associated) and increased multiple clinical features, which involve serious therapeutically and curative troubles for clinicians.
The aim of this study it was to evaluate the curative efficiency of norfloxacin in kidneys diseases of dogs. This drug is conditioned by different therapeutical preparations (injectable or oral administration) and comfortable periods between administrtations, and also its well known bioavailability in urinary structures seems to be the main reason in the recommendation for the treatment of kidney diseases.
This study was performed on 31 dogs with different inflammatory kidney diseases and different clinical features after treatments with norfloxacin using injectable (batch No.1) or oral (batch No.2) administrations. The curative efficiency registered after injectable treatments was of 85,7% (n = 12, after oral administrations of 70,5% (n = 14).

Abstract:
The main goal of this paper is to calculate TFP (total factor productivity) in agriculture by using the productivity index. The Malmquist productivity index has become common in practice by applying the nonparametric programming techniques to calculate TFP as ratios of distance functions. In this study, the TFP index is divided into technical change, technical efficiency change and scale efficiency change. The study was implemented using a panel set of data from 46 farms from the north region of the Republic of Moldova over the period 2004-2006, in order to measure and compare their productivity growths.
