he response of Isa Brown laying hens during 77–85 weeks age to peeled unfermented cassava root meal (CRM) as total substitute for maize in diet was examined. Eighty (80) were assigned four dietary treatment groups (T1,T2,T3 and T4) a completely randomized design. The control (CD) contained 40% while the proportion CD replaced with 100, 110 120% CRM amounting 40, 44 48% T2, T3, T4 respectively. ...

A field experiment was undertaken on farmers’ fields adjacent to a large mine tailings dam in the Zambian mining town of Kitwe. Experimental plots were located close (? 200 m) or further away (300–400 within demarcated land farmed by same community. This study evaluated uptake Cd, Cu, Ni, Pb and Zn pumpkin leaves maize grown soil amended with lime manure applied at agronomic rates, subsequent r...

Maize is a vital nutritional cereal for the infants, young children and adults. The environment which they are cultivated in Africa could expose to metal accumulations from soils, thereby posing health risks consumers. objectives of this study were determine maize grains (Zea mays L.) close Gosa Gwagwalada solid waste dumpsites their via consumption. A total 36 soil samples (12 each dumpsite so...

increasing diversity and apply intercropping systems is one of approaches to control of weeds. to evaluate the effects of additive maize-bean intercropping on yield, yield components and weeds in zanjan conditions, a field study was conducted in a spilt plot with randomized complete block design in three replications at research farm of zanjan university in 2010. main plots were the different p...

new sources of maize resistance to the maize weevil, sitophilus zeamais infestation are indispensable in successful breeding programs against post harvest grain damage. the study investigated the characters and mechanisms that confer resistance to weevil infestation using twenty elite maize genotypes. detailed morphological and physical studies were conducted on whole-maize grain. the grain hul...

intercropping systems are one of the best approaches in development of sustainable agriculture. based on this purpose, the present study was conducted to evaluate effect of strip intercropping on maize and bean growth analysis and their yield during 2009. the experiment was set up in a completely randomized block with 3 replications and 6 treatments based on replacement design. the treatments w...

To identify countermeasures to the effects of climate warming on crop production, we mustunderstand the changes in crop phenology and the relationships between phenology and climatechange and cultivar. We used summer maize phenological and climate data in the North ChinaPlain, collected from 1981 to 2010. This study analyzed the spatiotemporal trends inphenological data and lengths of different...
