Effect of intercropping of Alfalfa and perennial grass on some soil chemical properties.
Authors
Abstract
In order to determine the effect of intercropping of alfalfa and perennial grass on some soil chemical properties, Achivement to sustainable agriculture, This study carrid out in 2013 in Broujerd Agricultural Research Station.Trial conducted in Randomized Complet Block Design (RCBD) in 25 treatments and three times. Treatments including proportions of Medicago sativa and perennial grass (Dactylis glomerata, lolium persicum, lolium perenne, Festuca arundinacea, phalaris atoudinacea, Bromus inermis ) (25,50,75 and 100 percentages ). Replacement design were employed for intercropping treatments. In this study EC and PH in depth of 0-60cm in soil were assessed. Results showed that treatments were not significantly ( α=1%) affected on EC and PH. Comparisons of treatment (DMRT) showed that the highest of EC was obtained in Alfalfa(75%)+ Lolium persicum (25%) and the lowest was obtained in Alfalfa (25%)+ Bromus inermis (75%).The highest PH was obtained in Alfalfa(75%)+Dactylis glomerata (75%) and the lowest was obtained in Bromus inermis (100%).
