Augalinių liekanų užarimo įtaka vasarinių miežių pasėlio derlingumui

Abstract

The aim of experiment was to establish spring barley crop residues incorporation to soil by different types of ploughs dependence on crop yield and weediness. The research was carried out at in the Experimental Station of Lithuanian University of Agriculture during 2009-2010. Research objectives were crop residues incorporation to soil dependence on ploughing quality, spring barley crop weediness and yield. Plant residues and weeds were incorporated into soil best by the two-layer plough. Two-layer plough, even up to six-time reduced non-incorporated biomass of weed residues on soil surface and to 10 times reduced crop biomass after ploughing-in compared with the control treatmnent, ploughing with cultural plough. The grain yield of spring barley statistically had no significant differences, except in treatment of ploughing by the semi-helical plough were was established significant yield decrease compared with the control treatment
