Povzetek


Raziskava analizira učinek uporabe mehanizacije na produktivnost pridelave riža na izbranih kmetijah v južni Gani. Rezultati modela stohastične analize mejne funkcije podatkov anketiranja 360 pridelovalcev riža v južni Gani so pokazali, da imajo na produktivnost v povezavi z mehanizacijo značilen pozitiven vpliv naslednji dejavniki: velikost obdelovalne površine, obseg uporabe zaščitnih sredstev in gnojil, intenzivnost obdelave zemljišča, intenzivnost mlačve, izobrazba in intenzivnost transporta. Po drugi strani so intenzivnost žetve, prekomerna uporaba gnojil in starost kmetovalcev negativno vplivali na produktivnost v povezavi z mehanizacijo. Dobljeni rezultati so pomembni za ustvarjanje dodatnih kompetenc kmetov in pri vladni podpori za povečanje pridelave na kmetijah riža.

Ključne besede
