The experiment was to study the effects of replacing soybean meal by rubber seed meal on growth, economics and carcass characteristics of broiler. A total of 150 day-old commercial broiler (Cobb-500) was reared for a period of 35 days. There were five treatments including T0 (without rubber seed meal), T1 (10% rubber seed meal), T2 (20% rubber seed meal), and T3 (30% rubber seed meal) and T4 (4...

to determine the effects of steckling weight and planting density on seed quantitative and qualitative characteristics of monogerm sugar beet c.v. 9597, this experiment was carried out in ardabil agricultural research station in two years (1998-99). in this study, steckling weight with three different sizes(including 4.5 mm seed portion, velocity and unifomity of germination and decreasing of g...

objective: ageing of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. accelerated ageing has been recognized as a good predictor of the storability of seed lots. aged seeds show decreased vigor and produce weak seedlings that are unable to survive once reintroduced into a habitat. the characteristics of the chemical composition of...

in order to study the morphological, phenological and yield characteristics of 70 desi chickpea genotypes, a trial was conducted on 2007 in research farm of agriculture faculty of ferdowsi university of mashhad. in this study, 70 desi chickpea genotypes from ferdowsi university of mashhad seed bank, were planted in plots without replication including one to four planting rows at maximum length ...

Variation among forests in environmental and biotic conditions may strongly influence seed fate with important consequences for the abundance and distribution of plant species. Here we examine the post-dispersal seed removal rates of six pioneer species (Cecropia peltata,Miconia argentea, Luehea seemannii, Trema micrantha, Apeiba aspera and Jacaranda copaia) from the soil surface at five sites ...

in order to study the phenological and morphological characteristics, comparison of yield and yield components, correlation between traits and determination of the parameters affecting seed yield, a field experiment was carried out at the research farm of shahrekord university in 2007. ten lentil genotypes were compared by a randomized complete block design with three replications. the analysis...
