High Rye Seeding Rates Prove Effective for Weed Suppression

Published

A new Weed Science Society of America research article shows a generously seeded cereal rye cover crop helps reduce weed pressure for organic no-till soybean production

WESTMINSTER, Colo., July 14, 2026 /PRNewswire/ — A Weed Science Society of America (WSSA) journal, Weed Science, recently published a research article showing that a cereal rye cover crop helps reduce weed pressure for organic no-till soybean production, particularly when seeded at higher rates. The two-year research study reviewed field experiments conducted during the 2021-2022 and 2022-2023 growing seasons near Rock Springs, Pennsylvania, at the Pennsylvania State University Russell E. Larson Agricultural Research Center.

“The aim of this study was to compare the magnitude of weed control and soybean yield under different cereal rye densities within the soybean phase of cover-crop based organic rotational no-till production,” states Laurel Wellman, a Ph.D. student in plant sciences at Pennsylvania State University, and the study’s corresponding author. “Our results indicated that all cereal rye seeding rates reduced weed biomass compared to the unseeded cereal rye control plots, and that the higher cereal rye seeding rates reduced weed biomass significantly more than the lower seeding rates.” 

In two experiments, the researchers evaluated rye cultural management strategies for rye biomass, weed suppression, and soybean yield. They tested: 

four rye seeding rates (0.5-3 bu. acre) and two sowing arrangements (grid vs. row sowing)fall-applied poultry litter (0, 1.5, 3 tons acre) with two soybean planting dates (planting green or standard planting). 

“Increasing cereal rye seeding rate did not lead to increased rye biomass but did increase weed suppression,” points out Wellman. “Soybean yield was unaffected by rye seeding rates, and sowing arrangement did not affect any response.” 

Interestingly, “while fall poultry litter significantly increased rye biomass, weed suppression was unaffected,” she adds.

During one of the two cropping seasons studied, planting green reduced soybean establishment and yield, note the researchers. However, they also state that “these results highlight the limitations of organic no-till soybean production within grain crop rotations in the Northeastern U.S. when using cereal rye as a stand-alone weed suppression method. Increasing cereal rye seeding rates or applying fall fertility could be effective cultural practices when integrated with other weed control tactics to supplement weed suppression by rye surface mulch.” 

Overall, and perhaps most importantly, notes Wellman, the study “indicates that higher cereal rye seeding rates improved weed suppression independently of cereal rye biomass.” 

More information about the study is available online in the article: “Cultural management of cereal rye for weed suppression in cover crop-based organic rotational no-till soybean.” The research article is among others recently featured in Weed Science, a Weed Science Society of America journal, published by Cambridge University Press. Wellman can be contacted about the study at lew5444@psu.edu.

As AI Agents Scale, Enterprises Demand Execution Control — Devenex Takes Control

Published

on

By

LAS VEGAS, July 14, 2026 /PRNewswire/ — • Inside the world’s largest organisations, AI agents are no longer experimental. They are executing in production — modifying financial records, triggering payments, approving workflows, and acting with the full operational authority of the enterprises that deployed them. By every credible estimate, the volume and consequence of these actions will increase by an order of magnitude within 24 months.

Yet no infrastructure layer exists to govern what these agents actually do. No systematic policy enforcement before action. No immutable audit trail after. No deterministic control between an agent’s intent and its real-world consequence. The most consequential technology shift in enterprise history is unfolding without an accountability layer.

Today, that changes. Devenex — the Execution Control Plane for AI agents — launches at Google Cloud Next 2026, introducing enterprise-grade governance infrastructure that sits between agent intent and real-world execution. Every action is policy-evaluated, explicitly authorised, identity-bound, and recorded as audit-grade evidence — before it takes effect, giving new life to enterprise AI initiatives.

Devenex is not a monitoring tool. It is not a workflow engine. It is the control plane that ensures no AI-initiated action executes without governance — giving CIOs, CTOs, CROs and enterprise security leaders the confidence to deploy agents at scale without sacrificing accountability.

THE STRUCTURAL GAP

Analyst consensus has converged on a single conclusion: enterprise AI execution capability is outpacing the controls designed to keep it accountable.

Gartner projects that by 2028, a third of enterprise software will incorporate agentic AI — up from less than one percent in 2024. McKinsey identifies governance and risk as the primary barriers to scaling enterprise AI, ahead of model quality or talent. Deloitte’s 2026 enterprise survey finds that 80 percent of leaders piloting AI agents cite security and compliance as the leading obstacle — up from 68 percent a year earlier.

The pattern is consistent across every credible source: enterprises are deploying agents faster than they can govern them. An AI agent that modifies a customer record, approves a discount, or initiates a wire transfer without a governing policy layer is not automation. It is an unmanaged compliance event, a latent security exposure, and a board-level liability.

Devenex addresses this gap at the infrastructure level — not as a feature bolted onto existing tools, but as a purpose-built control plane designed for governed enterprise execution from the ground up.

THE EXECUTION CONTROL PLANE

Devenex operates as the authorisation and governance layer between enterprise decision-making — whether initiated by humans, AI agents, or automated systems — and the execution of actions across enterprise systems of record.

Every action processed through Devenex produces four structured artifacts:

Intent Record. 

Execution Plan. 

Governed Execution. 

Execution Evidence. 

This model ensures that enterprises maintain full traceability from intent to outcome — satisfying EU AI Act, SOC 2, ISO 42001, and sector-specific regulatory requirements.

ENTERPRISE CAPABILITIES

Pre-Execution Policy Enforcement.  Every agent action is evaluated against organizational policy before execution. Nothing executes unchecked. Enterprises gain control over what agents are permitted to do — reducing compliance risk and eliminating ungoverned action.

Dynamic Human-in-the-Loop Governance.  High-consequence actions are routed to designated reviewers without halting low-risk automation. Approval workflows are configurable at the agent, action, or policy level — ensuring human oversight where it matters without creating operational bottlenecks.

Immutable Audit Infrastructure.  Every governed execution is recorded to an append-only ledger. Enterprises gain continuous compliance evidence without manual reporting.

Unified Observability Across Agents.  Live and retrospective visibility into agent activity, policy adherence, and anomaly patterns. Security, compliance, and operations teams share a single authoritative view of enterprise execution.

BUILT FOR ENTERPRISE REALITY

Devenex delivers flexible deployment models—SaaS, hybrid, and self-deployed—enabling organizations to adopt at their own pace.

Engineered to be framework-agnostic and cloud-native, Devenex integrates seamlessly across diverse enterprise environments. The platform does not replace existing systems of record, integration platforms, or identity providers. It governs execution across them.

LEADERSHIP

“For four decades, Abacus has earned the trust of enterprises navigating their most consequential technology transitions. Devenex represents the next chapter — purpose-built infrastructure for a world where AI agents execute with the authority of the organisations that deploy them. Governance at this layer is not optional. It is a precondition for enterprise AI at scale.”

— Aly Kuly Khan
Co-Founder & Chairman, Devenex

“For four decades, we’ve built the layers enterprises run on — systems of record, integration, workflow automation, API and iPaaS governance. Each wave solved the problem the previous one created. Today, AI agents are executing actions on architecture that was never designed to govern them. This isn’t an AI problem. It’s an architectural gap — and it’s the one our experience has prepared us to solve. Enterprises cannot answer four questions about any agentic action: who authorized it, what policy governed it, why it executed as it did, and whether they can prove it after the fact. In regulated environments, these aren’t edge cases — they’re the baseline. Devenex is the execution control plane that answers all four, by design, at execution time.”

— Shoaib A. Khan
Co-Founder & CEO, Devenex

AVAILABILITY & ENGAGEMENT

Devenex is available immediately, with deployment support from Abacus teams across the globe.

Enterprise pilot programmes are open to qualified organisations seeking to bring governed execution to production AI workloads.

THE ROAD AHEAD

Enterprise AI is entering its execution era. The question is no longer whether agents can act — it is whether they can act accountably. The organisations that solve this first will scale AI faster, operate with greater confidence, and carry less risk than those that treat governance as a downstream problem.

Devenex exists to make governed execution the default operating model of the enterprise. Not as an aspiration. As infrastructure.

About DevenEx

Devenex is the Execution Control Plane for AI agents — enterprise infrastructure that governs every action across systems with policy enforcement, explicit authorisation, and audit-grade evidence. Built for the agentic era, Devenex sits between intent and execution so that no enterprise action moves forward ungoverned. Devenex is built by the team behind Abacus, bringing four decades of enterprise trust to AI execution governance.
