Žemės dirbimo intensyvumo, šiaudų ir žaliosios trąšos įtaka agroekosistemos komponentams miežių pasėlyje

Abstract

Conventional tillage system requires high energy and labor consumption and deteriorating soil properties. Study aim – to investigate tillage intensity, straw and green manure application effects on agro – ecosystem components in barley. It was established, that the number of barley plants on the third day after the beginning of germination significantly influenced by tillage intensity. Tenth day after the beginning of germination substantially less barley plants found in fields that have been applied rotary cultivator (RK). Tillage intensity (Factor B) and straw incorporation have no effect on the number of productive stems. Barley yield was signifficantly reduced by shallow ploughing and shallow loosening
