to study the genetic variation among 24 genotypes of tall fescue (f. arundinacea), a randomized complete block design of three replications was conducted under spaced plant conditions in karaj research institute of alburz, iran. analysis of variance showed high and significant differences (p

Rice (Oryza sativa L.) is an important global food commodity crop. Its yield was affected by genotype, environment, and the interaction between genotype environment that demands development of diverse tolerant rice to increase yields adaptation. Genotype Environment for Tongil types with doubled haploid (DH) were evaluated in three locations. A randomized complete block design replicated times ...

first of all, in order to determine the high yielding rapeseed varieties, two field experiments were performed in 2006-2008 cropping seasons in agricultural and natural resources research center of markazi province, arak (34º 5´ n; 49º 42´ e, and 1775 m above sea level), iran. in this research, 15 winter rapeseed varieties were compared in a randomized complete block design with three replicati...

Abstract Declining soil properties have triggered lower maize yields among smallholder famers in South Africa. Legume trees such as pigeonpea can be used improved fallows to replenish degraded soils. The objectives of the study were to: (1) examine effects on enhancing biological, physical and yield responses (2), analyze relationship grain biological after at Wartburg, Pigeonpea established 20...

to evaluate the effect of time and level of nitrogen application on quantity and quality of two carrot varieties, an experiment was carried out in the framework of a 4×3×2 factorial and based upon a randomized complete block design of three replications. the levels of 25, 50, 75 and 100 kg / ha of nitrogen fertilizer were investigated within 3 applied times, namely: simultaneous with bed prepar...

in this study, the mf285 tractor engine vibrations resulting from the use of different combinations of biodiesel, bioethanol and diesel as fuel were studied. engine vibrations in three directions and three engine speeds: 1000, 1600 rpm 2000 and ten fuel level was measured. to investigate the influence of measured parameters on engine vibration of factorial design in a randomized complete block ...
