Effectiveness of diferent methods for wild boar damage prevention on agricultural land

Štete od divljih svinja predstavljaju veliki problem poljoprivrednicima. Svojim ulaskom na zasijane oranice čine štetu najviše rovanjem i valjanjem i jedu poljoprivredne kulture. Poljoprivrednici štetu od divljih svinja umanjuju korištenjem trajnih i privremenih električnih ograda, repelenata, plinskih topova i drugih strašila. Cilj ovog rada je utvrditi učinkovitost različitih metoda, najveća pozornost je dana električnom pastiru i repelentima. Opisan je postupak postavljanja pastira te briga o istome. Fotografijama je prikazan sav potreban materijal za funkcionalnost električnog pastira kao i njegova učinkovitost. Kratko je opisano i postavljanje plinskog topa i repelenata čija učinkovitost je kratkoročna i ovisi o vremenskim uvjetima. Istraživanje je provedeno na području Posavine, na dvije oranice kukuruza te jednoj oranici lucerne i pira. Najveće štete su uočene u kukukurzu tijekom mliječno voštane zriobe te u piru i lucerni prije žetve. Iz priloženih fotografija se vidi da učinkovitost električnog pastira nije najbolja ali sprječava ulazak velikog broja divljih svinja.Damage from wild boars is a big problem for farmers. By entering the sown fields, they do the most damage by digging and rolling and eating agricultural crops. Farmers reduce damage from feral pigs by using permanent and temporary electric fences, repellents, gas cannons and other scarecrows. The aim of this paper is to determine the effectiveness of different methods, the greatest attention is given to the electric shepherd and repellents. The process of appointing a shepherd and taking care of the same is described. The photographs show all the necessary material for the functionality of the electric shepherd as well as its effectiveness. The installation of a gas cannon and repellents whose efficiency is short-term and dependent on weather conditions is also briefly described. The research was conducted in the area of Posavina, on two fields of corn and one field of alfalfa and spelled. The greatest damage was observed in maize during milk wax ripening and in spelled and alfalfa before harvest. The attached photos show that the efficiency of the electric shepherd is not the best, but it prevents the entry of a large number of wild boars
