The effect of pre-sowing magnetic treatments was investigated on germination, growth and yield of okra (Abelmoschus esculentus cv. Sapz pari). The dry okra seeds were exposed to sinusoidal magnetic field induced by an electromagnet. The average magnetic field exposure was 99 mT for 3 and 11 min and seeds with no magnetic field treatment were considered as control. Both treated and non-treated s...
BACKGROUND Phenotypic plasticity of fitness-related traits is vital for plant species to adapt to variable environments. Chenopodium glaucum L. and Amaranthus retroflexus L. are two common weed species globally. Understanding the plasticity in life-history traits, especially in reproductive allocation, within and among these species is important for predicting their success and for managing the...
The objective of this study was to investigate the effect of exogenous application of salicylic acid concentrations on the physiological and biochemical traits and essential oil content of chamomile under normal and heat stress conditions as induced by delayed sowing. The experiments were conducted during 2011–2012 as a factorial using a randomized complete block design with three replications,...
the present research was conducted under laboratory and field condition to determine seed priming effects on maize inbred line's germination, emergence, and grain yield. seeds of two maize inbred lines include of mo17 (as paternal line) and b73 (as maternal line with cytoplasmic sterility) in the laboratory conditions were subjected to hydropriming for 12, 24, 36 and 48 h, or osmoticprimin...
to evaluate the effects of sowing density, deferred harvesting, and harvest intensity on forage yield and an some vegetative characteristics of annual medic (medicago scutelatta var robinson) an experiment was conducted on the research farm of college of agriculture ,university of tehran ,karaj, during 2005 growing season. the expremental treatments were arranged in split-split plots based on a...
In order to evaluate effect of planting date and plant density on grain yield, yield components and some quality and morphological traits of chickpea (Cicer arietinum L.), an experiment was conducted at the research center of agricultural and natural resources of west Azerbaijan in Urmia rain-fed research farm during 2005-2006 growing season in a split plot arrangement, based on a completely ra...
The losses of water by evapotranspiration and evaporation from soil were investigated during two seasons from wheat and lupin crops sown at two times. Evapotranspiration was measured using ventilated chambers and microlysimeters were used within the chambers to measure evaporation from the soil surface. These techniques allowed the partitioning of evapotranspiration into its two components. In ...
To assess the suitability of Leguminous species in rice intercropping systems, physiological and morphological characteristics of Crotalaria juncea, Cajanus cajan, Mucuna pruriens var. cochinchinensis, Calopogonium mucunoides, Aeschynomene histrix and Stylosanthes hamata were determined in monoculture. C. cajan and S. hamata were selected and intercropped with two upland rice cultivars (WAB56-5...
Establishment of seedlings is a key factor in achievement of uniform field stands and, consequently, stable yields. Under Mediterranean conditions, soil moisture in the upper layer is limited and seedlings may be exposed to frequent dehydration events. The presence of the Reduced height (Rht)-B1b and Rht-D1b semi-dominant dwarfing alleles results in insensitivity to gibberellin (GAI) and, hence...
in order to evaluate phenological characteristics, yield and yield components of 18 cold tolerant lentil genotypes in fall planting under supplementary irrigation, an experiment was carried out based on randomized complete block design in 2006-2007 at research farm of college of agriculture, ferdowsi university of mashhad. irrigation was performed three times: immediately after sowing, 20 days ...
