We investigate the survival of new seeds in the US hybrid corn seed market between 2002 and 2007. Controlling geographic location, we find that product characteristics and market structure variables have significant impacts on the hazard of corn hybrids. The results also suggest spill-over effects of learning among close substitute seeds, and a spatial pattern of survival: seeds in the center r...

in order to investigate the effects of seed inoculation with plant growth promoting rhizobacteria (pgpr) on germination components and seedling growth of corn (zea mays l.), a factorial experiment based on randomized complete block design with three replications was conducted at the seed technology laboratory of mohaghegh ardabili university, iran, during 2008. studied factors were: corn cultiv...

Large and/or aged seeds are prone to hypoxic conditions during germination. Germination of selected vegetable seeds including corn (Zea mays L.), squash (Cucurbita pepo L.), and tomato (Solanum lycopersicum L.) was studied in water with different concentrations of hydrogen peroxide (H2O2) solution ranging from 0, 0.06% to 3.0% (v/v) or in aeroponics, all with 0.5 mM CaSO4. Imbibition, oxygen co...

Maize or Indian corn is, from the standpoint of total production, the second most important food plant in the world. No other crop is so widely distributed and only wheat occupies a larger acreage. Maize is noteworthy as a food because of its high content of carbohydrate, together with appreciable quantities of oil, protein, minerals, and other minor constituents. Food products made from field ...

This research was conducted to evaluate effect of potassium and iron fertilizers on agro-physiological traits affected different irrigation regime of corn in Shahryar (Tehran province, central of Iran) via a split-split plots arrangement based on randomized complete blocks design with three replications during 2015. The main plot included different irrigation regime (Normal irrigation and stop ...

Concerns about climate change and the increasing cost of fossil fuels have led to interest in the development of renewable biofuel pathways for reducing greenhouse gas (GHG) emissions. The use of corn residue as a potential source of biomass feedstock for cellulosic ethanol production has been favored as cost effective. Previous research has shown that crop residue removal can cause a loss of s...

The entomopathogenic fungus Beauveria bassiana infects a wide range of insects and survives as a soil saprophyte and a plant endophyte. The objective of our study was to determine the role of rainfall in dispersing B. bassiana (Balsamo) Vuillemin to the surface of corn (Zea mays) from soil with different levels of crop residue. Laboratory studies which simulated field tillage systems, had level...

Cadmium (Cd) contamination is a global environmental challenge that threatens human food security. Lime combined with five different organic materials (rape seed cake, mushroom residue, straw, sawdust, and corn cobs) (LOM) at application ratios of 1:1 lime sawdust nitro-compound fertilizer (Ca(NO3)2·4H2O, KH2PO4, KNO3) (LSF) rates were applied to Cd-contaminated soil. The present study investig...

Cornell University by seed industry legal restrictions placed on public scientists, limiting both laboratory and field research from the mid-1990s until 2010. Widespread and organized objections by corn entomologists from major agricultural universities in 2010, convinced the seed companies to loosen the legal restrictions limiting research by public scientists involving GMO crops. As a result,...

Field experiments were conducted during 2017 and 2018 to evaluate the efficacy of herbicides NICOSULFURON and EPTC alone or in combination with seed priming on weed control and corn yield. NICOSULFURON (80 g a.i. ha‒1) was applied at four- to six-leaf stage of corn as post-emergence and EPTC (4920 g a.i. ha‒1) applied as pre-plant incorporation (PPI). Among the herbicide treatments, the lowest ...
