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 ...

Corn Irrigation System
From Seed to Harvest: The Role of Corn Irrigation System Today we’re going to dive deep into the world of agriculture, focusing specifically on corn irrigation system. From the moment a corn seed is planted to the time it’s ready for harvest, irrigation plays a vital role. This process ensures that the crops get the right amount of water at the right time, which can significantly ...

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 ...

Irrigation water requirements for seed corn and coffee under potential climate change scenarios
The impact of potential future climate change scenarios on the irrigation water requirements (IRRs) of two major agricultural crops (coffee and seed corn) in Hawai'i was studied using the Irrigation Management System (IManSys) model. In addition to IRRs calculations, IManSys calculates runoff, deep percolation, canopy interception, and effective rainfall based on plant growth parameters, site ...

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 ...

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 ...

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 ...

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 ...

What do the A and C inside ABC Machinery stand for?
There are many types of soya oil mill plant, oil press models, such as 6Yl-120A and 6yL-68C. Then the customer has consulted. What do A and C mean? The previous number code is the same, only the English letter after the different. Here, we will help customers to answer. C stands for single machine. Single machine is the machine of sesame oil making machine. It does not include motor and belt. A ...

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), ...

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 ...

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 ...

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 ...

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 ...

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 ...

What’s Happening to the Birds?
Following in Rachel Carson’s footsteps, a new generation of scientists investigates a new generation of pesticides. Christy Morrissey is driving her white pickup truck along Canada’s endless prairie highway, windows open, listening for birds. She points to the scatter of ponds glinting in the landscape, nestled among fields of canola that stretch as far as the eye can see. Formed by ...

EPA Releases Preliminary Risk Assessment for Neonicotinoid Insecticide Imidacloprid
On January 6, 2016, the U.S. Environmental Protection Agency (EPA), in collaboration with California’s Department of Pesticide Regulation (DPR) announced the release of a preliminary pollinator risk assessment for the neonicotinoid insecticide, imidacloprid (Preliminary Risk Assessment or Assessment). In its assessment, EPA states that imidacloprid potentially poses a risk to hives when the ...

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 ...
