تأثیر کشت مخلوط بر عملکرد بیولوژیک، درصد نیتروژن و خصوصیات مورفولوژیک گشنیز (Coriandrum sativum L.) و شنبلیله(Trigonella foenum-graecum L)

Abstract

In order to study the intercropping arrangements of coriander (Coriandrum sativum L.) and fenugreek (Trigonella foenum-graecum L.), a field experiment was conducted during growing season of 2010 at Agriculture Research Station, College of Agriculture, Ferdowsi University of Mashhad, Iran. A randomized complete block design with three replications was used. Treatments included: mono-crop of fenugreek (A), %25 of optimum density of coriander + %175 of optimum density of fenugreek (B), %50 of optimum density of coriander + %150 of optimum density of fenugreek (C), %75 of optimum density of coriander + %125 of optimum density of fenugreek (D), %100 of optimum density of coriander + %100 of optimum density of fenugreek (E), mono-crop of coriander (F), %125 of optimum density of coriander + %75 of optimum density of fenugreek (G), %150 of optimum density of coriander + %50 of optimum density of fenugreek (H), %175 of optimum density of coriander + %25 of optimum density of fenugreek (I). Biological yield harvested in coriander at %5 flowering stage and in fenugreek at %20 flowering stage. The result showed that B treatment had highest plant height and biological yield of fenugreek, highest total land equivalent ratio and also B treatment had lowest essential oil contents of leaf, essential oil yield and biological yield of coriander. I treatment had lowest biological yield of fenugreek and it had highest essential oil contents of leaf, essential oil yield and plant height in coriander. Also A and E treatments had highest percent of nitrogen of biomass in fenugreek and coriander, respectively.
