irrigation requirement equals the difference between water requirement and effective rainfall which can be estimated by considering the water application efficiency. the values of water requirement and irrigation requirement of sugar beet have been reported using netwat program in different regions ofiran. however, the mean values were used in this program; therefore the values of water and irr...

in order to detect hydrogen cyanide gene and to determine pseudomonas fluorescent efficiency in producing hydrogen cyanide for controlling the growth of rhizoctonia solanipathogen (the causal agent of sugar beet root and crown rot), samples were collected from sugar beet rhizosphere in sabzevar fields. after soil sampling and purification, 31 pseudomonas spp. isolates were separated on specific...

This study aims to determine the effect of concentration kurut wood and jackfruit on yield, pH, percentage reducing sugars palm sugar. experiment used a completely randomized design (CRD) which consists 6 treatments, i.e., 0 g/L, 3 4 5 7 g/L. The data were analyzed by Analysis Variance (ANOVA) using Co-Stat software posthoc analysis for chemical score Orthogonal Polynomial Method (MOP). Statist...

using mulch to decrease and optimize water use, increase yield and fruit quality is known as a practical method. for this purpose, a split-factorial experiment based on complete block design with three replications on two melon cultivars was conducted in torbat-e-jam, iran. interval irrigation treatments in three levels (six, eight and 10 days) were considered as main plot and mulch (rice straw...

In order to study the effects of humic acid foliar spraying on morphological traits, photosynthetic pigmentation, and essential oil content of Dracocephalum moldavica, a factorial experiment was conducted based on a randomized complete block design with three replications in Saveh. The investigated factors included the use of humic acid at four levels 0 (control), 200, 400, and 800 mg/L and eth...

Stevioside is a natural sweetener from Stevia leaf, which is 300 times sweeter than sugar. It helps to reduce blood sugar levels dramatically and thus can be of benefit to diabetic people. Tissue culture is a very potential modern technology that can be used in large-scale disease-free stevia production throughout the year. We successfully produced stevia plant through in vitro culture for iden...

hargraves-samani method is one of the methods for calculating plant evapotranspiration that needs minimum meteorological data. in order to evaluate et-hs model in determining sugar beet crop water demand in isfahan, an experiment was conducted at research field of department of agriculture, khorasgan branch, islamic azad university, isfahan, iranin 2005. the study was based a randomized complet...
