Gyvojo mulčio įtaka kukurūzų pasėlio piktžolėtumui ir produktyvumui

Abstract

In 2009 the field experiment was carried out at the Experimental Station of the Lithuanian University of Agriculture on clay loam of average weight (Calcari-Hypogleyie-Luvisol) in composite maritime and continental climate conditions. The aim of experiment was to establish the interaction between maize and living mulch and its influence on maize crop weediness and productivity. Maize crop inter-rows were sown with spring oilseed rape {Brassica napus L.), white mustard (Sinapis alba L.), spring barley (Hordeum vulgare L-X Italian ryegrass (Lolium multiflorum Lam.), black medic {Medicago lupulina L.), Persian clover (Trifolium resupinatum L.) and red clover (Trifolium pratense L.) plants as living mulch. Living mulch competed with the maize crop and mostly decreased in yields and other growth parameters. Italian ryegrass living mulch was extremely aggressive and significantly decreased shoot dry-' biomass and grain yield of maize because of rapid sprouting up after each cut.
