In order to study the effect of phosphate solubilization microorganisms (PSM) and plant growth promoting rhizobacteria (PGPR) on yield and yield components of corn Zea mays (L. cv. SC604) an experiment was conducted at research farm of Sari Agricultural Sciences and Natural Resources University, Iran during 2007. Experiment laid out as split plot based on randomized complete block design with t...

C rop and fertilizer management practices can increase wheat grain protein without sacrificing yield. Growing wheat with high grain protein begins with selecting the appropriate variety and providing enough fertilizer to meet the wheat’s requirements for growth and grain yield. If nutrient levels are sufficient to meet yield goals, then providing adequate available nitrogen (N) may be the most ...

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...

Different winter barley cultivars showed various levels of genetic tolerance when they were exposed to different stress conditions. Therefore, investigations of interaction among genotypes (cultivars) and environments give useful information concerning yield stability and quality in barley (Blum, 1989; Ceccarelli et al., 1998, 2000; Lalić et al., 2007, 2009). Drought conditions frequently give ...

In order to evaluate the relationship between morphological characters in rice lines two populations at F3 generation were grown in research field of Agricultural Sciences and Natural Resource University, Sari, Iran, during 2012. Statistical analysis on important agronomic traits showed that maximum standard deviation belonged to total grain number followed by filled grains per panicle and grai...
