The milpa system is the basis of traditional agriculture in Mesoamerica. It based on a polyculture maize ( Zea mays L.), bean Phaseolus spp.) and squash Cucurbita associated with great diversity crops wild species. has cultural historical importance but can also be highly productive provide sufficient healthy diets for smallholder farmers. practiced less however, mainly due to socioeconomic cha...

A radioimmunoassay procedure for follicle-stimulating hormone in serum has been developed in which the assay mixture is incubated at 37#{176}C for a total of 22 h, rather than at 4#{176}C for 4-7 days. The withinassay coefficients of variation for the 37#{176}C and 4#{176}C methods, respectively, are 7.7% and 5.0%, while the between-assay variations are 13.8% and 9.9%. Comparison of values for ...

Background: Microbial and fungal contamination of agricultural produce has been a health challenge over the years. The present study surveyed microbial and aflatoxin contamination in groundnut, maize, and cowpea collected from Port Harcourt, Nigeria. Methods: Ninety samples of maize, groundnut, and cowpea were purchased from six major markets in Port Harcourt, Nigeria. The samples were first e...

We studied 29 girls and one boy with adolescent idiopathic scoliosis who were at Risser grade 0 at the time of posterior spinal fusion and were followed until maturity (mean 7.8 years). We used serial radiographs to measure the ratio of disc to vertebral height in the fused segments and to detect differential anterior spinal growth and assess its effect on scoliosis, vertebral rotation, kyphosi...

Intercropping systems compared to monoculture systems can more efficiently use the existing resources which ultimately will lead to increased plant performance. Therefore, to evaluate the benefits of intercropping maize and beans and assess its impact on yield and yield’s component, an experiment was conducted in factorial design with randomized complete block design in three replication, in 20...

this research aimed at investigating the effect of different levels of nitrogen and planting patterns on dry matter production and growth physiological indices in intercropping maize and sunflower. to do this a split plot experiment carried out based randomized complete block design with three replications in research field of shushtar islamic azad university. the main plot included three level...
