Effect of different concentrations of saffron corm and leaf residue on the early growth of arugula, chickpea and fenugreek under greenhouse conditions



In this study the effect of different concentrations of leaf (LR) and corm residue (CR) of saffron on seedling growth of fenugreek (Trigonella foenum-graecum L.), chickpea (Cicer arietinum L.) and arugula (Eruca sativa Mill.) as three potential companion crops for saffron were investigated under greenhouse condition. The experimental treatments were four concentrations (0.5, 1.5, 3 and 6 %) together with no residue treatment of LR and CR were arranged in completely randomized design. Results showed that the highest emergence percentage of chickpea was obtained at LR concentration of 6 %. Chickpea shoot length and mass had an increasing trend with increase in concentrations of saffron CR. LR and CR of saffron only at concentration of 3 and 6 % reduced the emergence percentage and emergence rate of fenugreek, but all concentration of CR and LR had no negative effect on length and mass of shoot. Saffron residue imposed a slight inhibitory effect on emergence percent and emergence rate of arugula, while had it a positive effect on some seedling growth characters especially root dry mass. Hence, three tested crops can be recommended as potential candidates to be associated with the saffron, although, the growth response of selected plants was dose-dependent and somewhat different.
