Nitrogen management strategies for smallholder maize production systems: Yield and profitability variability
Maize (Zea mays L.) production requires large amounts of nitrogen (N) thatdirectly affect production cost. Poultry litter can be used as an alternative source ofN. To optimize its use, poultry litter requires technical and economic feasibilityanalyses. Crop simulation models have proven to be efficient tools to support thistype of research. The objectives of this study were to determine yield a...
متن کاملNitrogen management strategies for maize production systems: Experimental data and crop modeling
Maize (Zea mays L.) is an important crop among Brazilian smallholder farmers,who are also responsible for 40% of the poultry and egg production in the country.Although poultry litter is considered a potential pollutant, if properly stabilized anddistributed in the field it can be used as a source of nitrogen for maize production.In this study, the response of maize to mineral fertilizer and pou...
متن کاملCHICKEN GENETIC RESOURCES USED IN SMALLHOLDER PRODUCTION SYSTEMS AND OPPORTUNITIES FOR THEIR DEVELOPMENT Smallholder Poultry Production
5 Author Poul Sørensen has many years of experience with poultry research. His particular interest is in breeding and genetics. He has contributed to the development of Danish poultry breeding since the beginning of his career and over time came to be the leading person in this area. With the intensification of poultry breeding worldwide he shifted his attention to the consequences of narrowing...
متن کاملStochastic human fatigue modeling in production systems
The performance of human resources is affected by various factors such as mental and physical fatigue, skill, and available time in the production systems. Generally, these mentioned factors have effects on human reliability and consequently change the reliability of production systems. Fatigue is a stochastic factor that changes according to other factors such as environmental conditions, work...
متن کاملfaciliting lexical access for the fluent production of speech
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
