Effects of magnetized water application on soil and maize growth indices under different amounts of salt in the water
Application of low quality water for irrigation is compulsive in facing water scarcity. Use of a magnetic field is an approach to overcome this challenge. This study examined the impact of magnetic field technology on improving germination under water of different salinity levels. An experiment was conducted to determine the effects of saline water levels, i.e. (S1):0.5, (S2):2, (S3):4 and ...

Predicting outcrossing in maize hybrid seed production
Controlling pollination of the female inbred is critical to achieve maximum kernel set and high levels of genetic purity in maize (Zea mays L.) hybrid seed production. Although kernel set associated with inbred flowering dynamics is fairly predictable, it has not been possible to predict the level of outcrossing resulting from adventitious pollen entering the seed field. Our objective was to ...

Cheap chemicals entice caterpillar-eating wasps to crops
It may be a win-win situation: treating seeds with commercially available growth promoters before planting could have the added benefit of attracting parasitic wasps that feed on caterpillar pests, suggests a study. The protective effect of these cheap, commercially available chemicals, known as ‘plant strengtheners’, can help protect young crops when they are particularly vulnerable ...

Use of pressure manifestations following the water plasma expansion for phytomass disintegration
A prototype capable of generating underwater high-voltage discharges (3.5 kV) coupled with water plasma expansion was constructed. The level of phytomass disintegration caused by transmission of the pressure shockwaves (50–60 MPa) followed by this expansion was analyzed using gas adsorption techniques. The dynamics of the external surface area and the micropore volume on multiple ...

THP9 Can Improve Protein Content and Nitrogen Utilization Efficiency in Maize Seeds
Teosinte is a wild ancestor of maize, and its seed protein content is three times that of most modern maize lines. In a new study, researchers from the Chinese Academy of Sciences and Shanghai Normal University tracked the mechanisms responsible for the decline in seed protein content in maize hybrids and inbred strains. Their findings open new avenues for maximizing seed protein content and ...

Supplementation of ogi, a maize-based infant weaning food, with African oil bean seed (Pentaclethra macrophylla Benth)
Maize ogi is a popular starchy porridge in the west coasts of Africa. Although consumed by adults as a breakfast cereal, its main use is as a weaning food for infants. In this study, the quality of ogi from a composite mixture of maize (Zea mays L.) and oil bean seed (Pentaclethra macrophylla Benth) flours was evaluated. Maize was substituted with oil bean seed at ratios of 90:10, 80:20, 70:30 ...

The profitability and risk of long-term cropping systems featuring different rotations and nitrogen rates
Yield comparisons do not provide the appropriate basis for decision-making regarding cropping systems. The dominant factor influencing the adoption of cropping systems is economics. The objective of this 15-yr study was to evaluate the long-term effect of four N fertilization treatments on the economic returns of seven crop rotations in Wisconsin, based on annual market prices and production ...

Zimbabwe`s New Farmers Fail to Deliver
HARARE, Zimbabwe, (ENS) - Six years after President Robert Mugabe sanctioned violent invasions of Zimbabwe's commercial farmland - mostly but not entirely white owned - by landless peasants, the facts show that the so-called new farmers have failed dramatically to produce crops to feed their countrymen. The poor peasants who led the invasions, at the behest of Mugabe, have since been driven ...

BUCHI NIR is Pro-Food Quality at ProFood Tech
The BUCHI wagon got put back on the road for the ProFood Techconference in Chicago this week. Hopefully you’ll catch us at our booth at Lakeside Upper Hall #3113 (vs. catching our booth attendants just lurking the show floor devouring free samples all day). ProFood Tech is an event, and BUCHI is a laboratory equipment manufacturer, but you might be interested in the overlap between us. We ...

Clothianidin in agricultural soils and uptake into corn pollen and canola nectar after multi‐year seed treatment applications
Limited data are available on the fate of clothianidin under realistic agricultural production conditions. This is the first large‐scale assessment of clothianidin residues in soil and bee‐relevant matrices from corn and canola fields after multiple years of seed‐treatment use. The average soil concentration from 50 Midwest US corn fields with 2 to 11 years of planting clothianidin‐treated ...

No evidence that Bacillus Thuringiensis genes and their products influence the susceptibility of corn residue to decomposition
The possibility that Bacillus thuringiensis (Bt) corn (Zea mays L.) residues resist decomposition compared to non-Bt residues would present direct (soil carbon turnover times) and indirect (changes in tillage practices) effects on carbon budgets in agricultural systems. We evaluated the relative decomposition of residue from two pairs of Bt and non-Bt corn hybrids from different seed ...

Crop gene banks are preserving the future of agriculture. But who’s preserving them?
As climate change makes crop diversity even more important, gene banks struggle to stay afloat. During the past few years of civil war in Syria, rebel fighters have destroyed Shia mosques and Christian graves, and burned and looted Christian churches while the Islamic State group has demolished priceless artifacts in the region. Nothing seemed sacred to the disparate groups vying for control of ...

Corn grain yield response to crop rotation and nitrogen over 35 years
Crop rotation and N are management methods that can increase corn (Zea mays L.) grain yields. Our objective was to determine the corn grain yield response to six crop rotation sequences and four N rates in a long-term (35-yr) study. The rotations were continuous corn (CC), corn–alfalfa (Medicago sativa L.) (CA), corn–soybean [Glycine max (L.) Merr.] (CS), corn-corn-corn-alfalfa-alfalfa (CCCAA), ...

Emergence of polymer-coated corn and soybean influenced by tillage and sowing date
No tillage often delays soil warming and drying, thus sowing too early in the spring may compromise seed viability due to prolonged exposure to cold and wet soil in the northern Corn Belt. Coating seed with a temperature-activated polymer may circumvent the adverse effects of exposing seeds to cold and wet soil. Germination and emergence of noncoated and polymer-coated corn (Zea mays L.) and ...

Fate and effects of clothianidin in fields using conservation practices
Despite the extensive use of the neonicotinoid insecticide clothianidin, and its known toxicity to beneficial insects like pollinators, little attention has been given to its fate under agricultural field conditions. The present study investigated the fate and toxicity of clothianidin applied every other year as a corn seed‐coating at two different rates, i.e., 0.25 and 0.50 mg/seed, in an ...
