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.

In order to achieve optimum quantitative and qualitative yield of potato in each region, new cultivars need to be compared. As such, this study has been carried out to compare 13 new potato cultivars along with two cultivars of Agria and Banba with each other to identify suitable cultivars for leaf area index, agronomic, and qualitative traits under climatic conditions of Razan. The statistical design, used in the present study, has been complete randomized block with three replications. Results show that Manito cultivar has reached the maximum leaf area index later than other cultivars, having 12 tubers per plant, which is 112% and 83% superior to Banba and Agria, respectively. Also, Natascha cultivar with a leaf area index of 3.65 has been 57% and 19% leafier than Agria and Banba, respectively. Tuber weight in Ottawa (157.8 g per tuber) has been 70.5% and 20.4% greater than Agria and Banba, respectively. Manito cultivar yields 71399 kg/ha, which is 123% more than Agria and 70% than Banba. Protein percentage of tubers in this study do not differ among the potato cultivars, while the difference is significant among the potato cultivars in tuber starch percentage and the highest values belong to Manito (18.09%) and Ottawa and Concordia cultivars, in the second and place. Generally, Manitou, Caruso, and Faluca cultivars are recommended for planting in the Razan on the basis of traits of maximum leaf area index, number of tubers per plant, and tuber yield.
