A field study was conducted on sandy clay loam soil to evaluate the impact of row spacing and N application method on the productivity of maize (Zea mays L.). The experiment was conducted using four row spacings (60 cm spaced single rows, 90 cm spaced double row strips, 90 cm spaced single rows and 135 cm spaced double row strips) and two methods of nitrogen (N) application (broadcast and band ...

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...

Nitrogen rate and time of application are among the major abiotic factors limiting productivity maize. The research was, therefore, carried out to examine response two maize varieties (Omankwa Pioneer hybrid) four different times N : P K 15 fertilizer during growing season in Ghana. experiment was arranged a randomized complete block design with eight treatment combinations three replications. ...

Storage is an important aspect of food security in developing countries. Therefore, it crucial for farmers to have access sustainable storage technologies cope with losses. Maize staple and commercial Rwanda, but maize are still being challenged by losses due lack proper facilities. It that regard advanced technology, notably hermetic technologyy has been introduced Rwanda its adoption low amon...

Wild maize (teosinte) has been reported to be less susceptible to pests than their modern maize (corn) relatives. Endophytes, defined as microbes that inhabit plants without causing disease, are known for their ability to antagonize plant pests and pathogens. We hypothesized that the wild relatives of modern maize may host endophytes that combat pathogens. Fusarium graminearum is the fungus tha...

Expression of the maize alcohol dehydrogenase 1 (Adh1) gene is transcriptionally regulated under conditions of anaerobic stress. DNA sequences required for the expression of Adh1 have been identified by a functional analysis of in vitro constructed hybrid genes consisting of the Adh1 promoter fused to the chloramphenicol acetyltransferase coding region. A series of 5' deletions, 3' deletions, h...

BACKGROUND Iron (Fe) deficiency is the most common micronutrient deficiency worldwide. Iron biofortification is a preventative strategy that alleviates Fe deficiency by improving the amount of absorbable Fe in crops. In the present study, we used an in vitro digestion/Caco 2 cell culture model as the guiding tool for breeding and development of two maize (Zea mays L.) lines with contrasting Fe ...

Effects of yard waste compost and maize (Zea mays) cultivar on population densities of plant-parasitic nematodes were examined in four experiments in north Florida. In one experiment, eight maize cultivars were evaluated; the other three experiments involved split-plot designs with compost treatments as main plots and maize cultivars as subplots. The three compost treatments used in these exper...

Targeted mutagenesis using programmable DNA endonucleases has broad applications for studying gene function in planta and developing approaches to improve crop yields. Recently, a genetic method that eliminates the need to emasculate the female inbred during hybrid seed production, referred to as Seed Production Technology, has been described. The foundation of this genetic system relied on cla...

A study was conducted at Bunda College during the 2003/04 crop season to assess the effect of fertilizer application practices on performance of maize with emphasis on improving the efficiency of using urea as a top dressing fertilizer The treatments were laid out as a split-plot in a randomized complete block design (RCBD) with maize varieties as main plots and fertilizer application practices...
