Maize production in Thailand is increasingly suffering from drought periods along the cropping season. This creates need for rapid and accurate methods to detect crop water stress prevent yield loss. The study was, therefore, conducted improve efficacy of thermal imaging assessing maize prediction. experiment was carried out under controlled field conditions Phitsanulok, Thailand. Five treatmen...
to study the phenotypic and genotypic diversity of some important agronomic traits associated with yield in white beans, 30 genotypes of white bean were evaluated using a randomized complete block design with four replications in two environments under water stress and non stress conditions. analysis of variance for most of the traits showed significant differences among genotypes, indicating t...
Drought stress is the most important factor which negatively effects the plant growth and crop productivity in arid and semi-arid areas. Therefore, in a field experiment, the effect of Salicylic acid (0, 0.5 and 1mM) and Methyl jasmonate (0, 5 and 10µM) was studied on growth parameters and bulb yield of a Primavera cultivar onion under water stress conditions in 2015. The results showed that dr...
Chlormequat chloride (CCC) as one of the most important growth retardants has been used for manipulation of growth and yield of cereal crops; however, the effect of CCC has not yet been well understood under drought stress conditions. Therefore, one greenhouse and a field experiment were conducted to examine the effects of CCC on yield and yield components of wheat in drought conditions at Coll...
Drought stress is one of the most important abiotic stresses influencing performance of crop plants. Therefore, the identification or development of tolerant genotypes is of high importance for incorporating in cotton production. In this study to evaluate the effect of drought stress on some cotton traits, 5 improved cotton varieties were studied in a split plot design with three replications i...
In most wheat growing moderate regions and especially in the north of Iran climate, is affected grain filling by several physical and abiotic stresses. In this region, grain filling often occurs when temperatures are increasing and moisture supply is decreasing. The experiment was designed in RCBD with split plot arrangements with four replications. Four irrigation treatments included (I0) no i...
Investigating the crop response to the deficit irrigation and evaluating the effect of drought stress on plant is one of the most important issues in crop production. In these circumstances, the use of organic fertilizers can play a mitigative role. Hence, an experiment was laid out as split plot based on randomized complete blocks design with three replications in Research Farm of University o...
abstract this research was conducted in toroq experimental field station, mashhad, iran, for two successive cropping seasons (2000-2002), using split plot experimental design based on complete randomized blocks with three replications. moisture stress treatments (at seven levels) were assigned to main plots, including: d1 ( full irrigation), d2 (no irrigation from one-leaf to double ridge) stag...
In order to investigate yield, yield components and quality traits of P. ovata and P. psyllium under water stress and plant density, two experiments were conducted at the Agriculture Research Field, University of Tehran, Karaj, in April 2005 and 2006. Two Factorial experiments based on randomized complete block design with three replications were used. The treatments were three levels of water ...
In order to evaluate traits related to drought stress in eight sesame (sesamum indicum L.) genotypes, two experiments were carried out in randomized complete design with three replications in the field of the Research Station of College of Agriculture, Shiraz University, Iran. The two experiments differed with respect to their irrigation regimes. Yield related traits (number of days to maturati...
