  Salinity and waterlogging are two abiotic stresses decrease plants yield. In this research, the effects of soil salinization and waterlogging having concentrations of calcium (Ca), potassium (K), magnesium (Mg) and sodium (Na) and K:Na ratio in corn (Zea mays cv. single cross 704) root were studied under greenhouse conditions. A factorial experiment with two factors on the basis of completely randomized design with three replications was performed. The factors under study were: waterlogging duration in five levels (0, 2, 4, 8, 20 days) and soil saturate extract salinity in four levels (0.11, 2, 4, 8 dS/m). A loamy sand soil for plant growth substrate and NaCl salt for establishing the levels of salinity was used. The salinity and waterlogging factors were imposed simultaneously to the plants from the five-leaf stage of plant growth period. The plants were harvested 60 days after sowing and the concentrations of Ca, K, Mg and Na in corn root were determined by dry ashi method. The results showed that by increasing the level of NaCl salinity in the soil, the K concentration and K:Na ratio of corn root were decreased significantly but concentrations of Ca, Mg and Na in corn root were increased significantly. The Mg and Na concentrations of root in waterlogged conditions were significantly lower than that of non-waterlogged conditions but the K and Ca concentrations of root in waterlogged conditions were significantly greater than non-waterlogged conditions. However, the effects of soil waterlogging duration on the Ca, K, Mg and Na concentrations and Na:K ratio of root were dependent on the level of NaCl salinity in the soil. The results demonstrated that even short periods of soil waterlogging had considerable long-term effects on the concentrations of Ca, K, Mg and Na and K:Na ratio in corn root under saline and non-saline conditions.

  In order to investigate the effect of mycorrhiza fungi on nutrient uptake of barley in rain fed conditions, a field experiment was carried out in factorial analysis based on randomized complete block design with three replications at the farm station of Sarablah Agricultural Research Center, Ilam during 2019-2020 cropping season. Experimental factors were four barley cultivars (Mahali, Mahoor, Khoram, and Fardan) and fertilizer application including: control (without fertilizer application and mycorrhizal fungi), 50% P chemical fertilizer recommended based on soil test (25 keg/ha), mycorrhizal fungi (Glomus mosseae, Glomus etunicatum, and Rhizophagus irregularis), mycorrhizal fungi along with 50% P chemical fertilizer, and 100% P chemical fertilizer as recommended. Results indicated that interaction between cultivar and fertilizer sources had significant effect on nitrogen, phosphorus, potassium, magnesium, iron, copper, and manganese. Interaction of Fardan cultivar and mycorrhizal fungi + 50% phosphorus fertilizer resulted in the highest nitrogen (11.1%), phosphorus (1.19%), potassium (3.92%), magnesium (0.292%), iron (136.5 mg.kg-1) manganese (65.8 mg.kg-1), and copper (65.71 mg.kg-1) in leaves. According to the obtained results, in the rain fed conditions, the new cultivar Fardan is recommended with mycorrhizal fungi along with 50% phosphorus fertilizer given the high concentration of high macro elements (nitrogen, phosphorus, potassium and magnesium) and micro elements (iron, manganese, and copper) and the role of these elements in plant growth and photosynthesis  Manuscript profile

  Little is known about the uptaken nutrient distribution and their relationship with the tendency of dry matter accumulation within the spike of wheat, whereas such findings are important for increasing grain yield without quality loss. In this research, we aimed to identfy the distribution of macro elements like calsium (Ca) and potassium (K) and micro elements like Manganese (Mn) and zinc (Zn) in different parts of spike (distal, middle and proximal) and spikelet (large and small seeds) during the duration of grain filling in two different varieties of wheat named: Mahdavi and  Falat. The results showed that the highest weight was obtained for the grains in the central part of spike as compared to the proximal and distal parts. Mn and Zn concentrations were decreased during the grain filling in three parts of the spike. There was a positive correlation between grain weight and concentration of macro – micro elemnts at various parts of spike. This correlation was stronger in the central part as compared other parts of spike (top and base). There was a considerable decrease of Mn and Zn in the seeds produced at the top of spike. However, a low concentration of elements in relation to the position of seeds on the spiklet was more remarkable than of that in the spike. There was no significant differences between two varieteis examined in this study in respect of nutrient distribution along the rachis and in rachilla. Manuscript profile

  In order to investigate the effect of different amounts of potassium and manganese on qualitative and quantitative yield and other traits of sugar beet in the northern of Khuzestan, a split block experiment was conducted based on complete randomly block with 12 treatments in three replication in fall cropping season October 2013-2014 in farmland of Haft Tapeh area of Susa city. A resistant mono germ genotype with high yielding named Spartak was used in this study. Examined factors included employing potassium fertilizer treatment in four levels of 0, 1, 2 and 3 kg/ha and manganese fertilizer in 0, 1, 2 kg/ha rates. Spraying with potassium fertilizer had a significant effect on root and white sugar yield. The highest root and sugar yield in treatment were achieved with 3 kg/ha of potassium fertilizer with 80.6 ton/ha root yield and 13.63 ton/ha white sugar yield. Using manganese fertilizer hadn’t significant effect on root yield and other studied traits. Also, using different rates of potassium and manganese fertilizers did not have much influence on qualitative characteristics of sugar beet such as nitrogen, sodium and potassium amounts in root, sugar extraction coefficient, molasses percentage, raw sugar and white sugar percentage. On the whole, using potassium and manganese during the vegetative growth stage of sugar beet is recommendable. Manuscript profile
