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...
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...
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...
Seed from maize (corn) Zea mays provides a ready source of 9-lipoxygenase that oxidizes linoleic acid and Iinolenic acid into 9(5)-hydroperoxy-1 0(8, 12(Zl-octadecadienoic acid and 9(SJ-hydroperoxy-1 0(£), 12(Zj, 15(Zl-octadecatrienoic acid, respectively. Corn seed has a very active hydroperoxide-decomposing enzyme, allene oxide synthase (AOS), which must be removed prior to oxidizing the fatty...
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...
ارزیابی عملکرد اقتصادی و کارایی مصرف نور در کشت مخلوط و خالص ذرت و پنبه تحت تاثیر سطوح مختلف نیتروژن
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...
