The critical period for weed control (CPWC) is the period in the crop growth cycle during which weeds must be controlled to prevent unacceptable yield losses. Field studies were conducted in 2005 and 2006 in the University of Birjand at the south east of Iran to determine CPWC of corn using a randomized complete block design with 14 treatments and four replications. The treatments consisted of ...
Green semilooper, Naranga aenescens Moore (Lepidoptera: Noctuidae) is a major pest in paddy fields of northern Iran. Since plant resistance to pests is a method with high efficacy and safety, a research was conducted to evaluate the resistance of 12 rice varieties (including, Tarom, Shafagh, Hybrid, Khazar, Poya, Fajr, Kados, Shiroodi, Sahel, Tabesh, Nemat and Neda) to N. aenescens on the basis...
Aquilegia `Rose-White' flowered from seed in about five months without vernalization. GA4/7 treatment increased stem height, induced earlier flowering, and increased the number of flowers/ plant. Each of these responses, however, was dependent upon both rate (10, 25, or 50 ppm) and timing of application (4-, 8-, or 12-leaf stage). Treatment at the 4-leaf stage resulted in earlier flowering at a...
this study aims to investigate value conflicts between mothers and their daughters among families and influential factors on this conflict in yazd city. this study adopted a survey method and a questionnaire was used that its validity through construct validity (factor analysis) and its reliability by cronbach alpha were measured. the population of this study consists of all yazdian families th...
Many researchers have reported positive effects of converter sludge and slag, two by-products in Isfahan iron melting factory. In this work, the optimum rate of application and the availability of some essential elements (for plant growth) in the converter sludge and slag for corn were investigated. The converter sludge contains about 64% Fe ІІ and ІІІ oxides and some other essential elements f...
in order to study the effects of foliar application of zn and k on yield and some physiological traits of spring safflower (carthamus tinctorius l.), cv. esfahan 14, under drought stress, a pot experiment was conducted in research greenhouse of yasouj university. experiment was a factorial based on completely randomized design with three replications. factors consisted of drought stress (s1- wi...

In order to investigate the effect of planting date and sowing method on ear yield, water use efficiency and some physiological characteristics of sweet corn, an experiment was carried out as a split plot based on a randomized complete block design with three replications in Yasouj, south-west of Iran. Planting date consisted of five levels (4 May, 19 May, 4 June, 19 June, 5 July) and considere...
images obtained from (b) hypercapnia and (c) ischemia study, respectively, during Stages 2 to 3. The time indicated below is the image sampling time after the termination of Stage 2 (S2). The arrows point to the sinus vessel. The total image averaging times for Stages 2 to 3 (i.e., S2, S3) were: 2.5, 6.5 minutes for the hypercapnia study; and 1.0, 1.8 minutes for the ischemia study. Stage 2 Sta...
