The present study has been conducted to compare new sugar beet cultivars for quantitative and qualitative traits in autumn sown condition as randomized complete block design at Safiabad agricultural and natural resources research and education center in 2017-2018. It has included 22 new sugar beet cultivar, investigated in three replications. Measured traits included number of leaf in plant, root yield, sugar content, white sugar content, white sugar yield, extraction coefficient of sugar, sodium, potassium, α-amino nitrogen, molasses sugar, and alkaloid ratio. The results show that all the measured traits in the cultivars have differed significantly. Highest root yield and white sugar yield are obtained from Callas and Honey cultivars with 125 and 113 ton/ha root yield and 13.5 and 13.6 ton/ha white sugar yield, respectively. Highest sugar and white sugar content with 15.75% and 13.63% are obtained from Sporta. Highest and lowest extraction coefficient of sugar are related to Sporta (86.5%) and Sharif (72.6%), respectively. The range of sodium, potassium, and α-amino nitrogen content has been from 1.54 to 4.26, 2.25 to 3.95, and 1.78 to 3.22 mEq, respectively. In total, to achieve maximum income for the farmer it is recommended that Callas and Honey cultivars or other cultivars that are in the same group with these cultivars should be used to obtain maximum root and sugar yield.

Abstract
The effects of chemical fertilizer of urea in 5 levels (0, 30, 60, 90 and 150 kg ha-1) and biofertilizers in 4 levels (Nitroxin, Phosphate barvar2, mixed of both and control) on quantity and quality yield of valerian are studied during 2016 to 2020. Measured parameters include valernic acid (percent), ...

The effects of chemical fertilizer of urea in 5 levels (0, 30, 60, 90 and 150 kg ha-1) and biofertilizers in 4 levels (Nitroxin, Phosphate barvar2, mixed of both and control) on quantity and quality yield of valerian are studied during 2016 to 2020. Measured parameters include valernic acid (percent), valernic acid (g ha-1), root dry weight (kg ha-1), shoot dry weight (kg ha-1), root diameter (mm), root length (cm), leaf width (cm), and leaf length (cm). This study is carried out at the Homad-Absard Agricultural Complex in Damavand city, Tehran Province, Iran, as factorial layout based on a randomized complete blocks design with 3 replications. Results show that the biofertilizers have had a significant effect (p≤0.01) on the all quantity and quality parameters studied. Unlike the urea chemical fertilizer at all levels, which have had a negative effect on the yield and amount of valernic acid (percent), bio-fertilizers has increased it. Maximum and minimum amount of valernic acid (percent) are measured in control and 150 kg ha-1 urea, respectively. The highest root dry weight belongs to interaction of Nitroxin+ Phosphate barvar2+150 kg urea (665 kg ha-1) and control (221 kg ha-1) respectively. Results of this experiment show that biofertilizers with positive effects on the parameters are able to replace the chemical fertilizers.

In order to study the effect of methanol and humic acid on physiological traits, yield and water use efficiency in plant of chicory under drought stress conditions, a split factorial experiment based on randomized complete block design with three replications in a field of Islamic Azad University, Birjand Branch in year of 2015. Irrigation at three levels (irrigation after 70, 140 and 210 mm cumulative evaporation from the evaporation pan) as the main factor and methanol spray at two levels (zero and 21 percentage volume) and humic acid with two levels (zero and 10 L ha-1 ) were as sub factors. The studied traits were chlorophyll meter, stomatal conductance, leaf relative water content, dry yields of root, stem and leaf dry, dry yield of total, root to stem and leaf ratio, water use efficiency of root, stem and leaf and total. The results showed that water deficit stress reduced all physiological and yield traits (except root to stem and leaf ratio) and increased water use efficiency. Application of methanol increased all of the traits (except yield and water use efficiency of root). Application of 10 L ha-1 humic acid increased all the traits (except for the ratio of root to air organs). In general, based on the results of this study, irrigation treatment after 140 mm evaporation from the pan and spraying methanol with 21 percentage volume and humic acid at 10 liters per hectare can be used to achieve yield acceptable for the Chicory plant in the Birjand region.
