The aim of this study was to investigate the effect of irrigation period on the quality and quantity of yield and some morphological and physiological traits of three multigerm sugar beet genotypes named BP Mashhad, BP Karaj and 191. The experiment was in a split plot based on randomized complete block design , carried out at Motahari Research station of Sugar beet Seed Research Institute ...
Multiple Brassica species commonly grown in Georgia were evaluated as a potential alternative to methyl bromide for management of root-knot nematode in vegetables. Brassica species produce general biocides called glucosinolates and were grown as cover crops and incorporated as green manures prior to transplanting of vegetable crop. Nematicidal activity of the Brassica species was based on net c...
Low soil phosphorus (P) availability is a major constraint for crop production in tropical regions. The rice (Oryza sativa) protein kinase, PHOSPHORUS-STARVATION TOLERANCE1 (OsPSTOL1), was previously shown to enhance P acquisition and grain yield in rice under P deficiency. We investigated the role of homologs of OsPSTOL1 in sorghum (Sorghum bicolor) performance under low P. Association mapping...
A field experiment was carried out at the Research Center of Barkat-e-Jovein, Jovein agro-industries, Northeastern Iran, during 2008 to evaluate the effect of concentration and time of boron foliar application on root yield and quality of sugar beet (Beta vulgaris). Treatments consisted of 3 application times (30, 45 and 60 DAP) and 4 application rates (spraying with concentrations of 0, 4, 8 a...
The effect of elevated [CO2] on wheat (Triticum aestivum L. Veery 10) productivity was examined by analysing radiation capture, canopy quantum yield, canopy carbon use efficiency, harvest index and daily C gain. Canopies were grown at either 330 or 1200 micromoles mol-1 [CO2] in controlled environments, where root and shoot C fluxes were monitored continuously from emergence to harvest. A rapid...
in order to investigation of waterlogging stress effects on morphological and physiological traits of rapeseed in different developmental stages, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental...
Reducing water requirements and lowering environmental footprints require attention to minimize risks to food security. The present study was conducted with the aim to identify appropriate root traits enhancing rice grain yield under alternate wetting and drying conditions (AWD) and identify stable, high-yielding genotypes better suited to the AWD across variable ecosystems. Advanced breeding l...
planting pattern can be adjusted by changing row spacing and row width, one row and two- row planting and plant interval on rows. in order to obtain the optimum planting pattern of a monogerm hybrid cultivar and its effect on the quantitative and qualitative characteristics of this cultivar, an experiment was conducted in two years (2001-2002) in zarghan area of farsprovince. the measured chara...
Water scarcity and salinity are important limitations for saffron (Crocus sativus L.) production in arid and semi-arid regions. The purpose of this research was to study the interaction effects of water salinity and deficit irrigation on the macroscopic water extraction model for saffron. The effect of salinity and water stress on root-water uptake coefficient was determined by additive and mul...
