Introduction Members of the Poaceae family have been rewarding subjects of research in the field of functional-structural plant modelling (FSPM) (Fournier et al., 2007). Poaceae comprise important cereal crop species such as rice, wheat, and maize, and the plants usually exhibit a regular and co-ordinated development making them particularly suitable for FSPM. The models that have been reported...

The influence of weed seed predation by invertebrates and vertebrates was examined in relation to distance from hedgerows in maize fields of southwestern Michigan. Experiments were conducted in spring and winter and included five common weed species, i.e., velvet-leaf (Abutilon theophrasti), redroot pigweed (Amaranthus retroflexus), common lamb's-quarters (Chenopodium album), fall panicum (Pani...

To detect and identify six varieties of genetically modified (GM) maize, polymerase chain reaction (PCR) assays were performed in the present study. The effect of heat treatment on the detection of the genes by the PCR methods was investigated. Maize samples were subjected to 100 ̊C and 121 ̊C heat treatment for different time intervals, and PCR tests were then conducted by using primers specific...

Maize streak virus (MSV; family Geminiviridae, genus Mastrevirus), the causal agent of maize streak disease, ranks amongst the most serious biological threats to food security in subSaharan Africa. Although five distinct MSV strains have been currently described, only one of these - MSV-A - causes severe disease in maize. Due primarily to their not being an obvious threat to agriculture, very l...

Agrobacterium tumefaciens-mediated transformation is an effective method for introducing genes into maize. In this chapter, we describe a detailed protocol for genetic transformation of the maize genotype Hi II. Our starting plant material is immature embryos cocultivated with an Agrobacterium strain carrying a standard binary vector. In addition to step-by-step laboratory transformation proced...

The construction of complex objects, such as an aircraft, requires the creation of a dedicated industrial system. By industrial system, we mean all the material and immaterial means used to build the object (labor, machines, factories, etc.). Classically, this means of production is defined after that the design of the product. In other words, the specifications of the product are the requireme...

Intercropping is an ancient agricultural practice that provides a possible pathway for sustainable increases in crop yields. Here, we determine how competition with wheat affects nutrient uptake (nitrogen and phosphorus) and leaf traits, such as photosynthetic rate, in maize. In a field experiment, maize was planted as a sole crop, in three different intercrop configurations with wheat (a repla...

Low yield of maize continues to affect the livelihood of smallholder farmers in the Zabzugu-Tatale area despite the introduction of a high yielding Obatanpa maize variety. The study used a cross-sectional survey design with 240 randomly sampled household heads growing maize to examine determinants of adoption of Obatampa varieties (IMVs) by farmers in the Zabzugu-Tatale area in the Northern Reg...

In order to study the potential of maize-cotton intercropping for improving radiation use efficiency (RUE), an experiment was conducted as a factorial arrangement based on completely randomized block design with three replications at experimental filed of Ferdowsi University of Mashhad. The experimental treatments were nitrogen in four levels (0, 50, 100 and 150 Kg N ha-1) and planting pattern ...

In order to study the effect of different intercropping combinations on some maize qualitative traits, an experiment was conducted as a completely randomized block design with three replications in Agricultural Research Station, Faculty of Agriculture, University of Tabriz, Iran, in 2006 and 2007. Two maize (Zea mays L.) hybrids (704, 301), vetch (Vicia villosa), bitter vetch (Vicia ervilia), b...
