Abstract

Introduction: Fenugreek (Trigonella foenum-graecum L. ) that belongs to the Fabacecae family, has been commonly used as a traditional food and medicine (Mehrafarin et al., 2011). Several experimental and clinical studies support beneficial effects of fenugreek in the management of metabolic diseases and inflammatory disorders. Water shortage is one of the most important limiting factors which reduces the growth of fenugreek and other plants around the world and the most common environmental Stress (Abedi and Pakniyat, 2010). In recent years, the excessive use of fertilizers and chemicals in agricultural production systems has increased the risk of environmental pollution and agricultural products. Bio-fertilizers as an alternatives or supplementary for chemical fertilizers, can guarantee the sustainability of agricultural production systems (Han et al., 2006). Therefore, considering the importance of bio fertilizers and water shortage, this experiment was conducted to study the effect of Mycorrhizal and green algae bio fertilizers on morpho-physiological traits and the relationships between these traits under low and conventional irrigation regimes. Materials and Methods: In order to study the effect of bio fertilizers on reducing the impact of drought Stress in fenugreek, an experiment was conducted in two-factor factorial format in a randomized complete block design with three replications in greenhouse conditions. The first factor was irrigation at two levels comprising without Stress (irrigation based on 100% soil capacity) and low irrigation Stress (irrigation based on 40% soil capacity), and the second factor was biological fertilizer at three levels (without bio fertilizer, use of Mycorrhiza fungi and use of green algae). The studied traits included chlorophyll, leaf relative water content, membrane stability index, plant fresh weight, grain yield, number and width of leaf stomata, number of pods and number of seeds per pod. Results and Discussion: The results of variance analysis showed that irrigation effect was significant for all traits except for the number of stomata. The effect of bio fertilizer on all traits was significant, and interaction between irrigation and bio fertilizer was significant for most of the traits except for the relative water content of the leaves. The highest grain yield (4. 55 g. plant-1) and the highest plant fresh weight (18. 06 g. plant-1) respectively, were obtained under non-Stress conditions and using Mycorrhiza. Using Mycorrhizal bio fertilizer under Stress conditions improved the majority of traits compared to non-use of bio fertilizer. Under Stress conditions, plant fresh weight had positive and significant correlation with the membrane stability index, grain yield, stomata number, stomata width and number of seeds per pods (Table 6 above the diameter of the table). Under non-Stress conditions, the correlation of plant fresh weight with grain yield, stomata number, stomata width, number of pods and number of seeds per pod was positive and significant (Table 6 below the diameter of the table). Under Stress conditions, positive and significant correlation was observed between grain yield with membrane stability index, plant fresh weight, stomata number, stomata width and number of seeds per pod (Table 6 above table diameter). Under non-Stress conditions, there was a positive and significant correlation between grain yield with fresh weight of plant, stomata number, stomata width, number of pods and number of seeds per pod (Table 6 below the diameter of the table). The Stepwise Regression showed that the number of seed per pod in Stress and non-Stress condition had the highest effect on grain yield, while the number of stomata in non-Stress conditions and the number and width of stomata in Stress conditions had the highest effect on plant fresh weight. Conclusions: A significant increase in quantity and quality of yield is achieved by paying attention to the relationships between yield and yield components and their effect on each other. The number of seed per pod; and the number of stomata and stomata width can be respectively used to improve grain yield and fresh weight of fenugreek under Stress conditions.
