A pot experiment was conducted at six graded levels of copper (Cu) viz., 0, 0.5, 1.0, 1.5, 2.0 and 2.5 mg kg(-1) to test the response of wheat plants grown in a copper-responsive alluvial soil (entisol) under glass house conditions. The growth attributes like plant height, fresh and dry matter yield, percent dry matter enhanced with increasing Cu levels and was maximum at 1.5 mg kg(-1) Cu while...

Grain size and weight are important determinants of rice yield. The identification of beneficial genes from wild rice that have been lost or weakened in cultivated rice has become increasingly important for modern breeding strategies. In this study, we constructed a set of chromosome segment substitution lines (CSSLs) of wild rice, Oryza rufipogon with the indica cultivar 9311 genetic backgroun...

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...

in order to effects of sulfur and manure on grain yield, yield components, and some physiological traits of corn hybrid ksc 704 in calcareous soils of kermanshah province, a factorial experiment was carried out based on a randomized complete block design with three replications. sulfur fertilizer in four levels 0, 250, 500 and 750 kg ha-1 and manure in four levels 0, 4, 8 and 12 t ha-1 were app...

the effect of perlite different amounts on grain yield and water use efficiency in winter wheat (cultivar of zarrin) in ghorveh (kermanshah province), was studied in 2007-2008. field experiment using completely randomized block design with seven treatments (p0, p1, p2, p3, p4, p5 and p6) including: zero (reference), 75, 150, 300, 600, 1200 and 2400 kg.ha-1 with four replicates was conducted. ir...

China has the biggest population all over the world. The food is always a problem faced by Chinese government. Therefore, to protect the land, which can grow the grain on, from decreasing is very important. However, with the development of economy, great deal of lands have been occupied by the factories and urban building. Development will make the land less, the food demand from the land is no...
