Objective: The aim of the present study was to evaluate artificial insemination techniques on reproductive performance in Ghezel ewes synchronized with CIDR during breeding season. Methods: All ewes were treated with controlled internal drug release device (CIDR) inserted into the vagina of the ewes for 14 days. All ewes were treated a single intramuscular (IM) dose of PMSG was injected. In thi...

Background and purpose: To assess the effect of equilibration time on the vitrified-warmed two cell mouse embryos. Material and Methods: Two cell embryos were obtained from oviducts of super ovulated female NMRI mice. The embryos were randomly allocated in four groups and vitrified using cryotop and two-step mediaprotocol. The experimental groups were: 1) embryos were equilibrated in vitrif...

Proximal sensing represents a growing avenue for precision fertilization and crop growth monitoring. In the last decade, agriculture technology has become affordable in many countries; Global Positioning Systems automatic guidance instruments proximal sensors can be used to guide distribution of nutrients such as nitrogen (N) using real-time applications. A two-year field experiment (2017–2018)...

Production of Mrenda (Corchorus olitorius) in Kenya has been low due to various reasons, such as poor agronomic practices like incorrect fertilizer rates. Observations from the Mrenda growing areas showed that there is high unmet demand for crop in local market and even for export. This is due to yields being low, 2-4 tons/ha as compared to expected yield of 5-8 tons/ha. Therefore, the main obj...

In order to study the effects of nitrogen application rate and timing on grain yield, phyllochron and leaf appearance rate of corn (Zea mays L.), an experiment was conducted as split plot based on randomized complete block design with three replications at the Research Farm of University of Mohaghegh Ardabili, Ardabil, Iran during 2009 growing season. Nitrogen rates were arranged in main plot w...
