Eight maize varieties viz. four composites (Mohor, Barnali, Khoibhutta, and BARI Maize-6) and four hybrids (BARI Hybrid Maize-1, BARI Hybrid Maize3, BARI Hybrid Maize Top 1 & Pacific 984), were tested for their response to zinc fertilization (0 and 3 kg Zn/ha) at the Regional Agricultural Research Station (RARS), Jessore (AEZ-11, High Ganges River Floodplain) during 20022005. The varieties were...

In order to evaluate the effects of seed priming with Plant Growth Promoting Rhizobacteria (PGPR) on dry matter remobilization and yield of maize (Zea mays L.) hybrids, a factorial experiment based on randomized complete block design with three replications was conducted in 2009 at the Research Farm of the Faculty of Agriculture University of Mohaghegh Ardabili. Factors included seed priming of...

Maize (Zea mays L.) is a staple food in many parts of Africa, but the endosperm generally contains low levels of the pro-vitamin A carotenoid β-carotene, leading to vitamin A deficiency disease in populations relying on cereal-based diets. However, maize endosperm does accumulate high levels of other carotenoids, including zeaxanthin, which is derived from β-carotene via two hydroxylation react...

The host status of 50 commercial maize hybrids for a Mississippi population of Rotylenchulus reniformis was determined in greenhouse experiments. Reproduction was measured by determining RF values ([final egg number + juveniles and vermiform adults in soil] / initial egg number) and number of eggs per gram of fresh root. All hybrids maintained R. reniformis below the initial population level, i...

In the hopes of lessening the current reliance on soil insecticides, developing a viable alternative for transgenic maize hybrids, and providing sustainable options for Europe, researchers recently have been developing novel maize lines that exhibit resistance and/or tolerance to corn rootworm larvae. Here we report the results of a 2-year field experiment in a northern growing region assessing...

The effects of plant density on dry matter accumulation, grain yield and yield components of four maize hybrids were evaluated. The experimental design was split plot format based on a randomized complete block with three replications. The study was conducted of Islamic Azad University of Dezful (Iran) farming research station in 2010. The main factors were 4 levels of hybrids (Ks.c704, Ks.c700...

Carbohydrates stored in vegetative organs, particularly stems, of grasses are a very important source of energy. We examined carbohydrate accumulation in adult sorghum and maize hybrids with distinct phenology and different end uses (grain, silage, sucrose or sweetness in stalk juice, and biomass). Remarkable variation was observed for non-structural carbohydrates and structural polysaccharides...

Field trials were conducted from 2007 to 2010 to compare grain fumonisin levels among non-Bt maize hybrids and Bt hybrids with transgenic protection against manual infestations of European corn borer (ECB) and Western bean cutworm (WBC). HPLC and ELISA were used to measure fumonisin levels. Results of the methods were highly correlated, but ELISA estimates were higher. Bt hybrids experienced le...
