Abstract
This study was performed to investigate the effect of four types of binders at different levels: carboxymethylcellulose (40, 60 and 80 g/l), arabic gum (50, 100 and 150 g/l), tragacanth (30, 60 and 90 g/l) and starch (45, 60 and 75 g/l) as the first test and four types of nutrients with different levels: ...

This study was performed to investigate the effect of four types of binders at different levels: carboxymethylcellulose (40, 60 and 80 g/l), arabic gum (50, 100 and 150 g/l), tragacanth (30, 60 and 90 g/l) and starch (45, 60 and 75 g/l) as the first test and four types of nutrients with different levels: humic acid (6, 9 and 12 g/l), filter cake ( 5, 10 and 15 g/kg), superabsorbent (10, 30 and 45 g/kg) and microcombi fertilizer (10, 20 and 30 g/kg) as the second experiment with control in a completely randomized design with 3 replications In 2020, in Khuzestan-Iran sugarcane research station. The results showed that the effect of four types of binder on sugarcane plant characteristics such as germination rate, stem length, stem dry weight and plant moisture content was significant and the most positive effect was observed in starch gum (60 g/l). Also, four nutrients had a significant effect on some characteristics such as germination rate, stem length, stem dry weight and plant moisture content. The most positive effect for characteristics was observed in humic acid (12 g/l). Due to the most positive effect of starch gum, in later studies, this glue can be used as a binder, along with other nutrients and fillers for planting lateral buds of sugarcane stems to produce artificial single-seeded sugarcane seeds.

This study attempts to investigate the effect of application of humic acid and seaweed extract on morphology, growth, yield, and yield components of quinoa under drought stress in 2018-2019 in two different locations, Qasr Shirin and Dalahou. It has been performed as split plots in a randomized complete block design with 4 replications. Experimental treatments include three irrigation treatments (full irrigation, irrigation cut-off at the beginning of flowering and irrigation cut-off at the beginning of seed filling) and foliar spraying treatments with different amounts of humic acid (foliar application at the rate of 1.5 kg / ha and 2 Kg / ha) and seaweed extract (foliar application at 1 kg / ha and 1.5 kg / ha) along with a control treatment. Results show that seed yield in Dalahou region under normal condation has been 24.78% higher than Qasrshirin region. Seed yield in different irrigation treatments under the influence of foliar application show that in all irrigation treatments, the effect of foliar application of humic acid and seaweed extract on seed yield has been positive compared to the control. In full irrigation conditions, the highest seed yield is obtained from foliar application of humic acid, while in irrigation cut-off treatments, the effect of seaweed extract on seed yield has been better than humic acid. The weight of 1000 seeds in quinoa produced in Dalahu region has been more than Qasrshirin region but in both regions drought stress has reduced the 1000 seeds weight. In all irrigation treatments, application of humic acid and algae extract has increased 1000-seed weight.

AbstractThis study aims at investigating the morpho-physiological responses of potato superelite mini-tubers to different coating treatments factorial experiment, based on randomized complete block design with three replications in Research Farm of Mohaghegh Ardabili University between 2018 and 2019. Experimental factors at four levels include mini-tubers filler (zeolite and cocopeat), superphosphate (soil and pellet application), chitosan, and superabsorbent with control treatment (without pelleting). Application of cocopeat with superphosphate leads to the highest average number of tubers per plant (8.36), fresh and dry tuber yield (18.23 and 3.88 tons per hectare), and biological yield (21.69 tons per hectare). The use of chitosan in mini-tuber pelleting decrease the activity of catalase and peroxidase enzymes (19.67% and 16.37%, respectively), increasing the activity of polyphenol oxidase (37.80%). Zeolite increase and cocopeat decrease the tuber protein percentage, compared to the control. This increase in protein percentage with increasing tuber yield leads to a 32.23% increase in tuber protein yield in zeolite application, compared to control treatment. The use of superphosphate in mini-tuber pelleting also increase the protein percentage, thus leading to a 30.30% increase in protein yield, compared to control mini-tuber. In principal component analysis (PCA), the first component, with which 35% of the changes could be explained, include the yield of protein, lysine, and methionine, and the second component, with which 25% of the changes could be explained, include the protein, methionine, lysine, and total nitrogen. Finally, the results show that the mini-tuber pelleting by superphosphate, zeolite, and superabsorbent have had significant additive effects on yield and quality traits.

This study aimed to evaluate the effect of sugar beet (Beta vulgaris) seed coating with organic fertilizer of Teprosyn, Kadostim and Zagroot on the emergence and seedling growth characteristics as factorial in a completely randomized design with three replications in 2015 at the Faculty of Agriculture and Natural Resources of Mohaghegh Ardabili University under greenhouse conditions. The experiment factors included seed washing (washing without washing), hybrids (Shokoufa and pars) and different amounts of organic fertilizers of Teprosyn, Kadostim and Zagroot, with control and adhesive treatments. The results showed that seed washing treatment increased the percentage of emergence, velocity of emergence and the percentage of plant establishment, and decreased the time to 10 and 90% of the emergence. Percentage of seed emergence in seed coating treatments with Zagrot (20 ml per kg of seed), with 95% emergence, seed coating with Zagroot (30 ml per kg seed), with 94.16% emergence were superior to other treatments. The percentage of plant establishment in the Pars hybrid was higher than the Shokoufa. Among different treatments of seed coating, seed treatment with Zagroot, had the highest leaf area and root and leaf dry weight. In general, in this research, seed coating with Teprosyn and Zagroot improved seedling growth and increased plant establishment.
