Economic justification of the distribution of the gross income at a farm
The problem of increasing the efficiency of the financial and economic activities in an agribusiness is based on rational distribution of means. From this point of view it is recommended to establish the optimal correlation between the expenses and the accumulated means. To determine the optimal correlation a specified economic-mathematical model should be used. We have added to this model the chapters on the formation and distribution of the profit and gross income.

Saiganov A.
Economic justification of the distribution of the gross income at a farm

The role of the meliorated soils in the system of soils distribution in Belarus
Mellorated soils have special role in Belarus. The soviet heritage is 3.4 million hectares of meliorated soils, including 2.9 million hectares of agricultural lands. Now it has become evident that because of the lack of means the state and the land udders cannon upkeep the infrastructure of meliorated lands. Determining the priorities for spending the limited means requires ecological and economic justifications. The article provides the information on knowing and using the environmental factors, which would make melioration ecologically and biosphere friendly as well as economically useful. Increasing the efficiency of utilizing the meliorated soils requires adaptive, resource saving technologies of planning and managing the melioration infrastructure.

The influence of weather and the type of substrate on the biochemical composition of tomatoes in Belarusian greenhouses
The comparative analysis of the biochemical composition of tomatoes (according to 43 characteristics) cultivated in the greenhouses of Brest and Minsk in the conditions of mineral cotton, water medium, high-moor peat and absorbent cialitis has demonstrated that the nutritive value of the production based on mineral cotton is considerably lower than that of the other substratum types.

The role of application terms of fungicide treatments in barley ear protection against Fusarium ear blight
The article provides the results of the research on the efficiency of applying fungicides to protect spring barley against Fusarium ear blight. The optimal terms of plant treatment has been determined at the appearance of barley head. The efficiency of the fungicides Falcon, 46% EC and Alto super, 33% EC turned out to be higher than the fungicides of Tilt, 25%i EC in the protection of barley ear against Fusarium ear blight.

About the necessity of applying the preparations of vegetative origin for protecting vegetable crops against pests
A possibility to apply the preparation of vegetative origin taboline isolated from the tobacco powder against vegetable crop pests in open and protected soil is demonstrated. The optimal concentrations and rates pf application of the two forms of the preparation are selected. It has been determined that the highest efficiency in relation to phytophages is in taboline 12, the preparation based on the tobacco powder by the method of its oxidation and the subsequent two step acid-alkaline hydrolysis. Taboline does not make phytotoxic effect on the protected plants of vegetable crops.

Semenenko N.
About determining the content of the main elements of nutrition the plants have access to in the degraded peat soils
On the basis of the analysis of the content of the combinations of nitrogen, phosphorous and potash the plants have access to the authors state that there are no analytical methods for examining anthropogenic-transformed degraded peat soils. I sing for the above purposes the methods of agro-chemical analysis specified by the state standards (GOSTs) for minerals lead to considerable (3-6 times) under-estimations of the content of movable combinations of phosphorous. And it is impossible to determine the content of the innate- and ammonia-nitrogen. To determine the content of the nitrogen, phosphorous and potash the plants have access to in the degraded peat soils it is suggested to apply the new method based on multi-component extracting, which provides for a more accurate assessment of the availability of the main nutrition elements in soils as well as for 3 times higher labor efficiency of analysts at 20-30% lower costs.

A system of protective measures management for weed control based on agrometeoro logical data
The main principles of creating a system of protective measures management for weed control in the conditions of Belarus based on agrometeorological data are stated. The criteria of the system optimization for a separate farm and region are determined. A single methodological approach to the logic and mathematical models is developed. Maximum using the agrometeorological data the authors suggest typical algorithms of forecasting the terms of herbicide treatments as well as the methods of optimizing decision taking, summarizing the statistical data. To select the best assortment of the herbicides the ecological and economic criteria of the management system as an integral indicator of economic, ecological, biological parameters of the formed phytosanitary field situation is proposed. The common informational resources for ensuring the algorithms are developed. The accuracy of the forecasted parameters, economic efficiency of operating the system are assessed and the final indicators are interpreted.

The influence of the different levels of mineral fertilizers application on the yield and the quality of oats grown the sod-podzolic light loamy soil
During the field test on the sod-podzolic light loamy soil the different systems of applying mineral fertilizers on oats, calculated for deficit, supporting and positive balance of phosphorous and potash with the crop have been studied. It has been established that the optimal system of applying fertilizers on oats is N60P40K80, which ensured the yield of grain at 37.3 c/ha. The article provides the data on grain quality (the content and the composition of protein, the composition of amino-acids).

The theoretical prerequisites of utilizing the natural cold in Belarusian agriculture
The theoretical justification of natural cold seasonal availability in the agricultural technologies was implemented by our scientists according to the multiyear aerography observations in all regions of Belarus. The regression models offree air thermal changes during the cold period of the year were charted as well as confidence intervals for these temperatures were fixed. That allows for forecasting the established agricultural energy saving opportunities in different climatic zones of the country at the expense of the seasonal use of the natural cold.

The foundation of automating the production in the conditions of upgrading the commercial pig breeding
The commercial production of pork has biotechnical nature and it should be treated as a most important managerial tool. The priorities in this sphere are automating the feeding process and up keeping the micro climate. From the program and technical point of view the automated systems should he based on the modern microprocessors, sensors and serially made devices. The architecture of the systems created should be open and provide for the vertical and horizontal integrations. Automating the production on the basis of the modern microprocessors can significantly reduce the cost of the production without major investments if applied during the upgrading of the existing enterprises.
