- Abstract
In the Republic of Srpska, as well as in other countries, fodder crops are a voluminous base of livestock production, which is why the companion of livestock development must be primarily a sufficient amount of highquality and readily available fodder. Regarding the potential of fodder crops growing, it is large in Republic of Srpska. The cultivation of this crop type of plants is accompanied by the influence of a number of organizational and economic factors, and establishing a good basis for production planning requires a qualitative analysis of its production parameters as well as identification of their tendencies. The author has four major fodder crops as a subject of the research (clover, lucerne, maize for fodder and fodder beet). The period covered by the analysis was from 1996 to 2018. The basic production indicators of selected fodder crop types (harvested area, total production and yield) for which the sources of data were statistical bulletins of agriculture published by the Republic of Srpska Institute of Statistics, were analyzed. The applied method involved the use of basic statistical indicators such as average value (arithmetic mean) and also measures of central tendency and dispersion (rate of change, coefficient of variation, interval of variation). The tendency is represented graphically through a linear trend model. The aim of the paper was to analyze the characteristics of fodder crops production on the basis of a twenty-three-year series of data and to establish the tendency of production of this crop of plants in Republic of Srpska. The results obtained show that the average area of total fodder crops in the observed period was almost 72.150 ha and that it showed a stable movement throughout the analyzed period. This is proved by the calculated coefficient of variation of 7.65%. In contrast, there was a slight tendency for the total area under fodder crops to fall, expressed by a rate of change of - 0.37%. Clover as the most common fodder crop achieved an average value of about 32,156 ha in the analyzed twenty-three year period. Unlike the variability of the total areas, the clover area shows greater instability in its movement (cv = 17.3%), as well as a tendency to fall (r = -1.61%). The production of clover, whose average value was at the level of 104,667 tons, shows almost the same tendency of fall, and the instability in movement is almost twice the instability of movement of its area in the observed period (36,21%). The yield of clover shows a slight tendency to fall (-0.13%) with an average value of 3.19 t / ha and a relatively large variability in its movement (cv = 25.44%). As far as lucerne is concerned, all three measured indicators show a tendency of mild growth, while the reported instability of movement in the observed period is similar to the movement of clover. The achieved average value of the area under lucerne was 20,007 ha, while the production was 75,101 tons and the yield was 3.73 t / ha. The analyzed production parameters of maize for fodder show a tendency of growth, the same as with lucerne. What is noticeable in maize for fodder is the great instability in movement of its production indicators over the observed period. This applies especially to maize for fodder production, where the measured coefficient of variation was over 68%. The average value of the area of this fodder crop was 5169 ha, while the average production reached the level of 95.183 tons, and the average yield was 17.6 t / ha. Fodder beet is the least represented fodder crop in Republic of Srpska with an average area of 630 ha in the analyzed period and production of 5319 tons. The average yield of fodder beet was 7.2 t / ha and it is the only productive parameter that showed a positive tendency of growth (r = 0.42%). The other two production indicators had a negative growth tendency, the largest of the fodder crops observed so far. There was a huge fluctuation in the production of fodder beet in the observed period (cv = 93.6%), as well as extremely high instability in the movement of areas under the fodder beet (cv = 58.2%).
