Comparison of yield in potato (Solanum tiberosum L.) grown method of soil and without soil

Cilj rada je usporedba prinosa krumpira uzgojenog metodom u tlu i bez tla. Krumpir je vrlo zastupljena kultura, četvrta iza pšenice, kukuruza i riže. Za potrebe rada postavljen je pokus s uzgojem krumpira na konvencionalni i nekonvencionalni način. Konvencionalni način je više zastupljen jer je jednostavniji, a podrazumijeva duboku jesensku obradu tla, sadnju u tlu, kultivaciju, ogrtanje, njegu i zaštitu nasada. Nekonvencionalni način proizvodnje podrazumijeva sadnju krumpira bez obrade tla. Sadnja se obavlja na neobrađeno, ili tek malo obrađeno tlo. Nakon sadnje dodaje se malč u nekoliko slojeva koji je potrebno više puta zalijevati. Rezultati provedenog pokusa pokazali su da je značajno veći prinos bio metodom uzgoja ispod slame odnosno bez tla nego metodom u tlu.The paper aim was to compare the potato yield grown by two methods in soil and without soil. The world potato production is at the fourth place, after wheat, corn and rice. For the trial purposes there was set up experiment with growing potatoes on conventional and unconventional way. The conventional method is more present, because it is simpler and involves deep autumn tillage, planting in soil, cultivation, wrapping up, care and protection of the plantation. The unconventional method of production involves planting potatoes without soil tillage Planting has to be done on uncultivated, or only slightly processed soil. After planting, mulch is added in several layers and watered more time. The experiments results showed that the significantly higher yield was getting by under straw method or without soil than with the method in the soil
