Changes in soil penetration resistance during spring and winter barley growing by soil conservation technologies
Promene penetrometrijskog otpora zemljišta pri gajenju jarog i ozimog ječma konzervacijskim tehnologijama
Slovak University of Agriculture in Nitra, Slovak Republic
Abstract
The field trials were set up with spring barley (variety Nitran) and winter barley (variety Gerlach) and different soil tillage systems (conventional A, reduced - B, minimum - C). It was determined that soil loosening was greater at the depth of 10 cm in the variants with medium deep ploughing than in variants with reduced and minimum tillage. Higher and more uniform values of penetration resistance were found in greater depths in the variant with medium deep ploughing. The values of penetration resistance in the variant with minimum tillage, with maize as a preceding crop and disc harrow as a tool, were greater over all depths than in the same variant but with sugar beet as a preceding crop. The overall analysis of gained results on penetration resistance indicates that soil tillage systems A and B provided better conditions for the growth and development of plants. Furthermore results gained in trials with winter barley variety Gerlach in 2006 show uniform values of penetration resistance over all observed depths and tillage systems. Results accomplished on penetration resistance in 2007 show small differences between tillage systems A and B, while values determined for the system C were higher approximately by 100% at the depth from 15 to 40 cm.
Sažetak
U poljskim proizvodnim uslovima sa jarim ječmom (sorta Nitran) i ozimim ječmom (sorta Gerlach) pri različitim tehnologijama obrade (A-konvencionalna B-redukovana i C-minimalna) utvrđeno je da varijante sa oranjem na srednju dubinu imale su veću rastresitost zemljišta na dubi većoj od 10 cm u poređenju sa redukovanim i minimalnim tehnologijama obrade. Za veće dubine za varijante sa oranjem na srednju dubinu utvrđene su veće i ujednačenije vrednosti penetrometrijskog otpora. Za tehnologiju C sa teškom tanjiračom čija je pretkultura bio kukuruz, izmerene su više vrednosti penetrometrijskog otpora za sve dubine u poređenju kad je pretkultura bila šećerna repa. Celovitom analizom izmerenih rezultata penetrometrijskog otpora za jari ječam utvrđeno je da za rast i razvoj biljaka, tehnologije A i B obezbeđuju bolje uslove. Za eksperimente sa ozimim ječmom sorte Gerlach u toku 2006. godine utvrđene su ujednačene vrednosti penetrometrijskog otpora za sve merene dubine i sve ispitivane tehnologije obrade. Rezultati merenja penetrometrijskog otpora u toku 2007. godine pokazali su male razlike između tehnologija A i B, a za tehnologiju C bile su izmerene više vrednosti za približno 100% na dubini 15 do 40 cm.
