In annual forage legumes such as the common vetch (Vicia sativa L.), in which the pods represent a substantial proportion of the total biomass, the optimum harvesting stage may not adjust to the classical model of decreasing nutritive value after flowering. The effect of harvest time on the yield of the main chemical components of common vetch was evaluated under field conditions typical of the...
In order to investigate the effect of concentration and time of supplementary nitrogen fertilizer spray on growth indices of rapeseed (cv. Hyola 401), a field experiment was conducted at Rice Research Institute of Iran as a randomized complete blocks design with 16 treatments and 3 replications in 2008-2009. The treatments included concentration of nitrogen fertilizer (urea) at two levels (5 an...
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 the effect of concentration and time of foliar spraying of nitrogen fertilizer as supplemenfary to soil nutrition on grain yield and some important traits of rapeseed (Hyola401), an experiment was conducted in complete randomized block design with 16 treatments and three replications in in 2008-2009, 2009-2010 growing seasons, and in 2003-2005 growing seasons in paddy field...
in order to evaluation of nitrogen fertilizer application and seed inoculation by azotobacter and azosprillium on yield, rate and grain filling period of corn sc-500 cultivar, a factorial experiment was conducted based on randomized complete block design with three replications in farm of agriculture and natural resource research center of azarbaijan-e- shargi province in 2011. the factors were...
in order to study of effects of integrated biological and chemical fertilizers on fertilizer use efficiency, grain yield and related traits to grain growth of barley (hordeum vulgaris l.), a factorial experiment was conducted based on randomized complete block design with three replications in research farm of the faculty of agriculture sciences, university of mohaghegh ardabili in 2012. tre...
Hormones play important roles in regulating the grain filling process and protein accumulation. In this study, two wheat cultivars differing in grain protein concentration were used to investigate the changes in endogenous hormone contents and the mechanism of hormonal regulation of grain filling and protein accumulation under exogenous application of abscisic acid (ABA) or gibberellic acid (GA...
degraded soils in northwest china are mostly nonproductive due to imbalanced nutrient and inadequate water supply. the effects of manure application at three different rates (7.5, 15.0, and 22.5 t ha–1) combined with chemical fertilizers on soil water and water-use efficiency in maize [compared with chemical fertilizers (control)], under semi-arid conditions in dark loessial soil and over a per...
In order to identify QTLs controlling agronomically traits, landrace Tarom and rice Tarom mutant were crossed. SSR, ISSR, iPBS and IRAP markers were amplified in 250 F2 individuals to prepare the linkage map. Number of tillers, 100 grain weight, number of filled grains, number of unfilled grains, plant height, panicle length, number of branches, stem diameter, grain length, grain width, grain s...
During grain filling in barley (Hordeum vulgare L. cv. Barke) reserves are remobilized from vegetative organs. Glumes represent the vegetative tissues closest to grains, senesce late, and are involved in the conversion of assimilates. To analyse glume development and metabolism related to grain filling, parallel transcript and metabolite profiling in glumes and endosperm were performed, showing...
