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) 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 perio...

In this study, interactive effects of microstructure and cavity dimension on the filling behaviors in micro coining were investigated. The results indicate that the filling ability is dependent on both the cavity width t and the ratio of cavity width to grain size t/d strongly. The critical ratio t/d for the worst filling ability increases with cavity width t and tends to disappear when the cav...

A field experiment was conducted during 2001-2003 to evaluate the effect of water stress on the yield and yield components of four rice cultivars commonly grown in Mazandaran province, Iran. In northern Iran irrigated lowland rice usually experiences water deficit during the growing season include of land preparation time, planting, tillering stage, flowering and grain filing period. Recently d...

Experiment was designed to establish a more defi nitive relationship of phenological and physiological traits with yield in wheat using twenty fi ve spring wheat genotypes. Because many of these traits are interrelated, correlation coeffi cient, path analysis and principal component analysis were used to expose these relationships more clearly. Experiment was conducted at the Wheat Research Cen...

individual grain weight of wheat kernels differs with their positions on a spike. cultivation practices (such as fertilizer nitrogen and plant growth regulators application) can be used to improve weight of basal and distal kernels. for this purpose, two experiments based on randomized complete block design were carried out with three replications. the aim of this research was to study the mech...

in order to compare morphophysiological traits between new and old cultivars of barley (hordeum vulgare l.) a greenhouse experiment was conducted in greenhouse condition in faculty of agriculture, ferdowsi university of mashhad in spring and summer 2011.the type of experiment was a completely randomized design with eight treatments (nosrat , youssof , fagr30 , nick) and four old cultivars inclu...

an experiment was conducted as a split plot based on complete randomized block design with three replications in the fall of 2010 at the farm of lorestan university, khorramabad, iran. four winter wheat cultivars (marvdasht, azar, shiraz and line m-79-7) as the main plot and levels of iron oxide nanoparticles (ion) along with control treatment were the subplot. iron fertilizer spraying was done...

introduction moisture limitation is considered as one of the important limiting factors in soybean growth. drought stress affects different aspects of soybean growth through making anatomical, physiological and biochemical changes (tarumingkeng & coto, 2003). under dry tension condition, there will be a disturbance in transmitting nutrients, but some useful soil fungi such as mycorrhiza improve...

Remobilisation of non-structural carbohydrates (NSC) from leaves and stems and unloading into developing grains are essential for yield formation of rice. In present study, three recombinant inbred lines of rice, R91, R156 and R201 have been tested for source-flow-sink related attributes determining the nature of NSC accumulation and translocation at two nitrogen levels in the field. Compared t...
