Many metal transporters in plants are promiscuous, accommodating multiple divalent cations including some which are toxic to humans. Previous attempts to increase the iron (Fe) and zinc (Zn) content of rice endosperm by overexpressing different metal transporters have therefore led unintentionally to the accumulation of copper (Cu), manganese (Mn) and cadmium (Cd). Unlike other metal transporte...
in this study, a complex crop model was developed that integrates the various components of swap and csm-ceres-maize (dssat v4.0) model with the purpose of developing a more efficient model and according to the internal requirements. in the hybrid model, ceres-maize supplies swap model with daily leaf area index and root depth and on the other hand swap model supplies ceres-maize with daily wea...
This research covered three villages in Kura local Government Area of Kano State. The study described the socio-economic characteristics of maize producers and their production techniques and also determined the profitability and resource use efficiency in the maize production. Structured questionnaires were used for primary data collection and 40 small scale producers were purposively selected...
maize genotypes were screened for host resistance and seed treatment chemicals were evaluated in field to manage fusarium ear rot complex of maize at high- and mid-hill environments in nepal during 2003 and 2004. seven popular maize genotypes along with a susceptible check were used in the host resistance study. the maize genotypes adopted from exotic sources, manakamana-3 and deuti, performed ...
The chemical control of weeds raises serious concerns about food safety and environmental quality, which have necessitated the need for non chemical weed management techniques such as intercropping. Intercropping can suppress weeds and reduce the use of herbicides in production systems. Therefore, the objective of this work was to evaluate the effects of intercropping of faba bean and maize, as...
Sixteen rams (mean age: 13 mo; mean live weight: 40.0 ± 2.4 kg) were randomly allotted to four dietary treatments in a completely randomized design (4 rams per treatment). Diets (dry matter basis) contained 65% concentrate and 35% alfalfa hay (control diet, T1), 35% wheat straw (T2), 35% barley straw (T3) or 35% maize straw (T4). Total-tract apparent digestibility for dry matter, organic matter...
Cadmium (Cd) contamination harms plant growth and human health. The application of hemin (ferroprotoporphyrin IX) can effectively relieve abiotic stresses in plants. This work investigates the effects on alleviating Cd toxicity enhancing tolerance maize seedlings. In this study, seedlings were cultivated nutrient solutions, with a combination CdCl2 (464 ?mol L?1) (100 L?1). We measured status, ...
BACKGROUND AND AIMS In maize (Zea mays), early flowering date, which is a valuable trait for several cropping systems, is associated with the number of leaves per plant and the leaf appearance rate. Final leaf number depends upon the rate and duration of leaf initiation. The aims of this study were to analyse the genotypic variation in the response to temperature of leaf appearance rate and lea...
in order to evaluate forage quality in intercropping, two field experiments were carried out based on randomized complete block design with three replications at the agricultural research station, faculty of agriculture, university of tabriz, iran, in 2005-2006 and 2006-2007 growing seasons. two maize (zea mays l.) hybrids (sc704, sc301), vetch (vicia villosa), bitter vetch (vicia ervilia), ber...
Cadmium (Cd) is a toxic heavy metal with no known biological function in plants and one of the most substances released into environment. Crops, such as rice, maize, wheat tobacco are major sources Cd for humans. toxicity inhibits crop growth development by affecting many central physiological biochemical processes, finally it affects human health via food chain. To adapt to toxicity, crops hav...
