agroforestry is one the aspects of sustainable agriculture in which multiple cropping of perennial trees in mixture with crops guarantees the environmental, economical and social sustainability in rural communities. high demands for forage in northern provinces of iran lead to agroforestry in citrus orchards as a potential mean for forage production through agroforestry systems. this research w...

an experiment was conducted on 240 one-day old ross 308 broiler chicks using a completely randomized design in a 2×3 factorial arrangement with two levels of nano-adjuvant (with and without) and three levels of dietary protein (low, medium and high) during a 42 d experimental period. the main effect of protein density on feed intake was significant during the starter and grower periods (p

Two experiments were conducted to examine the calcium requirements of broiler chickens fed corn-soybean meal diets. Experiment 1 used a 6 x 2 x 2 factorial arrangement and was conducted with broilers in floor pens during the grower phase (19 to 42 d). Diets were mixed with 6 levels of dietary Ca (0.325, 0.4, 0.475, 0.55, 0.625, and 0.9%) and 17 or 23% CP and fed to males and females separately....

Background Postpartum Bonding Questionnaire (PBQ) is a remarkable tool to assess impairments in the mother-infant bonding. The purpose of the present study was to review the factorial structure of the PBQ cross different versions. Materials and Methods The search strategy was implemented on databases of Medline (via PubMed), Scopus, Cochran library and Web of Science through electronic database...

ABSTRACT- As the world's population has grown and become more urban and affluent, waste production has raised drastically. Wastewater reuse has been identified as a way to alleviate water scarcity and improve crop productivity and environmental sustainability. To address the issue, a soil column experiment was carried out in a 3 × 3 factorial randomized block design including three treatments o...

peppermint (mentha piperita l.) from lamiaceae family is one of the most important medicinal plants, used in food, sanitary and cosmetic industries. a field experiment was carried out in ferdowsi university of mashhad in 2010-2011 to evaluate the effects of three irrigation levels (100, 80 and 60 percent of water requirements calculated by evaporation pan class a) and two mulch types (black pla...

Foldover is a widely used procedure for selecting follow-up experimental runs. As foldover designs require twice as many runs as the initial design, they can be inefficient if the number of effects to be dealiased is smaller than the size of the original experiment. Semifolding refers to adding half of a foldover fraction and is a technique that has been investigated in recent literature for re...
