20.500.12556/RUL-184345 Vpliv načinov obdelave tal na vznik in rast krompirja (Solanum tuberosum) The influence of soil preparation on potato (Solanum tuberosum) germination and growth Na domači kmetiji smo izvedli poljski poskus, kjer smo na posamezno poskusno polje posadili 200 gomoljev (100 v leho) in v katerem smo uporabili štiri različne postopke plitve obdelave tal in jih primerjali glede na število gomoljev, ki so kalili, količino pridelka, kakovost obdelave ter porabo goriva in časovno storilnost. Uporabili smo diskaste brane, predsetvenik in prekopalnik. Z diskastimi branami smo opravili osem prehodov, s predsetvenikom štiri in osem prehodov in s prekopalnikom en prehod. Največ gomoljev je kalilo pri obdelavi s prekopalnikom in najmanj pri obdelavi z diskastimi branami. Največ pridelka je bilo pri osemkratnem prehodu s predsetvenikom in diskastimi branami in najmanj pri štirikratnem prehodu s predsetvenikom in prekopalnikom. Najmanjšo porabo goriva na hektar smo dosegli s štirimi prehodi, srednjo porabo goriva s prekopalnikom in največjo porabo goriva z osmimi prehodi. Najboljšo površinsko storilnost je imel prekopalnik in najslabšo diskaste brane z osmimi prehodi. Pri obdelavi s prekopalnikom smo dobili največjo količino finih delcev v nižjih frakcijah velikosti pod 2 mm, drugi trije načini obdelave pa so nam dali podobne deleže frakcij s prevladujočimi v velikosti 2-4 mm. Glede na vse dobljene podatke pridemo do sklepa, da je najbolj smiselna uporaba prekopalnika, vendar je potrebno paziti na vrtilno frekvenco delovnih elementov med obdelavo, da se grude ne zdrobijo preveč, ker to vodi v zaskorjenost, po prvem dežju. On our family farm, we conducted a field experiment in which we planted 200 tubers (100 per row) in each experimental plot. We applied four different shallow tillage methods and compared them in terms of the number of sprouted tubers, yield quantity, quality of soil preparation, fuel consumption, and time efficiency. We used disc harrows, a seedbed cultivator, and a rotary tiller. With the disc harrows, we performed eight passes, with the seedbed cultivator, four and eight passes, and with the rotary tiller, one pass. The highest number of tubers sprouted in the treatment with the rotary tiller, and the lowest in the treatment with the disc harrows. The highest yield was achieved with eight passes using the seedbed cultivator and the disc harrows, while the lowest yield was obtained with four passes using the seedbed cultivator and the rotary tiller. The lowest fuel consumption per hectare was achieved with four passes, medium consumption with the rotary tiller, and the highest with eight passes. The highest field efficiency was achieved with the rotary tiller, and the lowest with the disc harrows at eight passes. Tillage with the rotary tiller produced the highest proportion of fine soil particles in the lower size fractions below 2 mm, while the other three tillage methods resulted in similar proportions of fractions, predominantly in the 2–4 mm size range. Based on all the obtained data, we conclude that the use of a rotary tiller is the most reasonable option; however, it is necessary to pay attention to the rotational speed during tillage to avoid excessive soil pulverization, which can lead to soil crusting. krompir obdelava tal predsetvenik prekopalnik diskaste brane potato tillage seedbed cultivator rotary tiller disc harrow true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-07-05 07:17:02 2026-07-05 07:17:08 2026-07-07 13:51:55 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 280505 283938307 59220.pdf 59220.pdf 1 633D957EC3A6072335C37924A17F1E83 81e4c2964470a2180ef69634e87882b684d19c4bdf16c6bb62e480fd760caa89 a78ea34a-7830-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=237025 Biotehniška fakulteta 0 0 0
