South Dakota Walking Your Fields newsletter-JulyDuPont Pioneer
This document discusses water usage and needs in corn crops. It notes that annual precipitation in South Dakota varies greatly from 13 to 30 inches, which can cause water stress or drought for corn depending on rainfall. Water is especially important during tasseling and from that stage through dent stage when corn demands 0.25 inches of water per day. Insufficient water can lower yields. While root growth can access more water, high temperatures also increase water needs, potentially doubling requirements in 90 degree weather. Water stress most impacts yields during pollination and grainfill. Maintaining soil moisture through irrigation can increase yields up to 30% by reducing evapotranspiration. The document provides details on corn water usage and loss through evapotranspiration and
ND & Northern MN Walking Your Fields newsletter-AugDuPont Pioneer
The document discusses corn drydown and harvest timing. It notes that corn planted in mid-late May or early June in the region will likely reach maturity later than usual. It also discusses factors that influence drydown rate like temperature, wind, and hybrid. The ideal harvest moisture is 22-25% but waiting until 18% risks losses from weather, stalk lodging and ear drop. Artificial drying costs vary depending on fuel prices but may increase profitability when losses are anticipated.
Western MN and eastern SD Walking Your Fields newsletter-JulyDuPont Pioneer
The corn crop is developing well with most fields reaching the VT (tassel) stage by August 1, which should allow crops to reach maturity before fall frosts. Growers who applied side-dress nitrogen prior to canopy closure are expected to see rewards from the recent rainfall. Corn rootworm and soybean aphid scouting should continue. Mark DeGroot has joined the DuPont Pioneer sales team as the new Account Manager for the territory covering Eastern South Dakota and Western Minnesota.

This document outlines alternatives for controlling field bindweed, a pernicious weed. It discusses cultural controls like preventing the spread of bindweed seeds and parts between fields. Physical controls include using black plastic mulch or fabric barriers. Crop rotations and cover crops can also help suppress bindweed by providing shade or competing for resources. Specific crop rotations and sequences involving forage sorghum, sunflowers, pumpkins, and alfalfa are highlighted. The document also describes a 5-year non-chemical strategy combining mechanical tillage and cropping.
1. Groundnut, also known as peanut, is an important oil and protein crop grown primarily in Asia, Africa, and the Americas. It is a self-pollinating, annual herbaceous legume.
2. Groundnut is predominantly grown in tropical and subtropical regions with rainfall between 500-1250 mm during the crop season. Ideal soil types are sandy loams with a pH between 5-5.5.
3. Groundnut seeds are usually sown in kharif season from June-July under rainfed conditions or in rabi/summer under irrigation. Proper sowing, weed, water and pest management are required to achieve optimal pod yields.
Grasshoppers are sporadic pests that sometimes migrate in large populations and defoliate gardens. More than 200 grasshopper species occur in California, but only a few like the devastating grasshopper and valley grasshopper cause significant problems. Grasshoppers lay eggs in soil in fall which hatch the following spring. Nymphs molt several times before becoming adults. Population sizes vary yearly, with major outbreaks occurring every 8-10 years if conditions are favorable for several years. Grasshoppers prefer young plants and remove large sections of leaves, sometimes devouring entire plants. Management options during major invasions are limited, but trap crops and insecticides around garden borders can help control smaller populations.
Weed management in maize,sorghum&perl millet plantsMahendra Anjana
This document discusses weed management in C4 plants such as maize, sorghum, and pearl millet. It identifies common weed flora including broad-leaf weeds and grass weeds. Yield losses from weeds can range from 20-30% but vary based on management practices. The critical period for weed control is early crop establishment to early reproductive stages from 30-60 days after sowing. Various weed management techniques are outlined including crop rotation, intercropping, seed treatment, soil preparation, hand weeding, mulching, fertilizer practices, soil solarization, harvesting at maturity, and chemical control options.
Dreamland Industries was formed in 2008 to help create rural prosperity by developing innovative crops. They have completed two harvests of safflower in Texas, Oklahoma, Kansas, and New Mexico. For 2011, they are looking to contract more safflower acreage. Safflower is a drought-resistant crop that produces vegetable oil and has other benefits like a deep taproot and minimal input needs. It can be grown with conventional equipment and has a relatively short 120-150 day growing period. Dreamland provides information on recommended planting dates, fertilization, weed control, harvesting, and yields to help farmers have a successful safflower crop.
The document summarizes the System of Rice Intensification (SRI) method of rice cultivation. SRI uses younger seedlings, wider spacing between plants, less flooding of fields, and other practices. It can significantly increase rice yields, often doubling average yields, while reducing water, seed, and other input needs. SRI goes against conventional agriculture wisdom but evidence shows it improves root and tiller growth, leading to higher productivity from existing rice varieties and genomes.

- The System of Rice Intensification (SRI) is an alternative methodology for growing rice that can significantly increase yields using fewer external inputs. It involves transplanting young seedlings with wide spacing, maintaining moist soil conditions, and mechanical weeding.
- SRI has led to increased yields of 8-16 tons/hectare in various countries, compared to average worldwide yields of 3.8 tons/hectare, through profuse tillering, greater root growth, larger panicles, and less water requirement. Additional benefits include lower costs, higher profits, and less need for fertilizers and agrochemicals.
- While counterintuitive, SRI principles take advantage of plant biology and dynamics
The document discusses the System of Rice Intensification (SRI), an alternative methodology for growing rice. SRI uses younger seedlings, wider spacing between plants, and reduced flooding of fields. It results in larger root systems and increased tillering. Studies have found SRI can double average yields to 8 tons/hectare while reducing water use by 50%, costs of production, and need for agrochemicals. SRI appears counterintuitive but reflects farmers' experiences of increased output from fewer external inputs under improved growing conditions.
This document summarizes research from a decade of cover crop studies at Western Illinois University:
1) Key lessons learned include the impact of cover crops on soil health, nutrient cycling, and suppressing crop diseases. Cereal rye was shown to improve soil structure and increase yields when diseases were present.
2) Research trials evaluated different cover crop species and varieties, planting times, and their effects on subsequent cash crops. Radishes and other brassicas improved soil penetration and water retention. Frost seeded red clover produced more biomass than other legumes.
3) Experiments tested no-till systems with cover crops, effects of added nitrogen, and strip-tilling techniques. Cereal rye facilitated successful
Alternate bearing in avocados is genetically encoded and can be difficult to manage. It is usually precipitated by abnormal crops that stress the tree's resources. While alternate bearing indexes show it is a problem globally, management strategies like pruning, nutrition timing, and growth regulators can help reduce its amplitude. Achieving the proper balance of vegetative and reproductive growth is key to stabilizing yields from year to year.
The document provides best practices for establishing and maintaining a Wadi programme, which involves planting fruit trees. It outlines recommendations for plot selection and marking, pit digging and filling, graft selection and planting, aftercare including staking, basin preparation, mulching, shade provision, and intercropping. Proper spacing, soil management, irrigation, and integrated pest management are emphasized.
Grasshoppers are difficult to control but their impact can be minimized through preventative management over the long term using non-chemical strategies. These include cultural controls like fall tillage to destroy eggs, trap cropping to concentrate grasshoppers, and encouraging natural predators. Biological controls such as the protozoan Nosema locustae and fungus Beauveria bassiana can be used against nymphs and adults. Physical barriers and traps can also help reduce grasshopper populations. Maintaining farm biodiversity is key to preventing major outbreaks.
Tissue culture is the propagation of plants using plant parts, single cells, or cell groups grown in a sterile, controlled environment. Banana is an important crop for India, contributing 37% of total fruit production. It grows best in tropical climates between 13-38°C with humidity of 75-85%. Good soil for banana has drainage, fertility, and moisture with a pH of 6-7.5. Common varieties include Grand Naine, which is becoming most popular for its stress tolerance and fruit quality. Land preparation involves adding organic matter to pits or furrows which are then planted with banana plants.

Dreamland aims to establish safflower as a sustainable crop that provides consistent profits for growers.
Competition occurs between organisms for limited resources essential for growth, such as water, nutrients, light, and space. Weeds are often more competitive than crops for these resources. The critical period of weed competition is the shortest time span during crop growth when weeding results in the highest economic returns, usually the first 1/4 to 1/3 of the growing period. Weed competition can reduce crop yields through competing for nutrients, moisture, light, and CO2. Soil fertility, moisture levels, and cropping practices like planting time influence the competitive relationship between crops and weeds. Allelopathy refers to the detrimental effects of chemicals released by one plant on another plant.
This document provides a guide for producing sesame. It discusses advantages of growing sesame, including its drought tolerance and ability to grow in soils where other crops fail. It covers topics like field selection, planting considerations, growth stages, moisture and nutrient needs, pests, and harvest. Sesame is heat tolerant and can be grown across the southern US. Proper soil moisture, fertility, and temperature influence the length of development stages from germination to harvest. The guide aims to help producers successfully grow and manage sesame crops.
The document discusses the alfalfa stem nematode (ASN), a microscopic roundworm parasite that infects alfalfa plants. It can reduce crop yield and quality by feeding on above-ground plant parts. ASN completes its life cycle in 19-23 days under ideal conditions and a single female can produce 200-500 eggs. Symptoms include stunted, twisted plants with crinkled leaves. Diagnosis involves examining plant samples under a microscope for nematodes. Highly resistant alfalfa varieties and crop rotations are recommended for management, as chemical controls are often ineffective.
2014 Stratego YLD® Impact of Disease on Late-Planted Corn Tech SheetStratego YLD Fungicide
Corn planting is significantly behind normal trends this year. Because there is a downward pressure on yields as planting dates are pushed back, it is important to get as much return as possible from each acre. The investment costs are much the same for early-planted corn as late-planted corn, so taking all of the steps possible to maximize the yield potential is a wise course of action.

These techniques include staggering plantings of the same crop, using taller plants to shelter shorter ones, and planting crops together that mature at different rates or attract different pests.
Wireworm Management in Horticultural Cropsacornorganic
Wireworms are the larvae of click beetles and can damage a wide variety of crops. They have a 5 year lifecycle and are difficult to control. Brown mustard and buckwheat have been shown to be effective in reducing wireworm populations as part of a crop rotation strategy due to compounds in the plants that are toxic to the larvae. Biological control using the fungus Metarhizium has also shown promise for controlling adult click beetles, which could then reduce wireworm populations over multiple years. Proper crop rotation, monitoring, and biological controls are all important aspects of an integrated wireworm management program.

DuPont Pioneer conducted corn population research trials across North America from 2001-2012. The results showed that the optimal seeding rate depends on yield levels, with higher rates needed for higher yields. For typical Midwest yields of 190-220 bushels per acre in 2013, the optimal economic seeding rate was found to be 34,600 seeds per acre. Hybrid improvements have allowed for higher populations over time, with the top yielding hybrids from 2009-2012 performing best at 40,000 plants per acre. Growers can use these results to determine the best seeding rates for their hybrids, locations, and management practices.
The enormous volume of farm-level data growers now handle—from new precision
ag technologies as well as from traditional information sources—can be unwieldy
and disconnected. Effectively using the data requires the ability to compile and
analyze it to make insightful decisions.
Commodity prices are softening, input costs are on the rise and access to land is a
key concern. To stay competitive, growers must closely manage their operations to
get the most out of every resource.
Growers can’t count on the markets or the weather—except to change. Staying in
business over time means effectively managing the risks growers can control
while minimizing the impact of those they can’t.
Improving sustainability is both a business requirement and good business.
Growers must produce more from every acre while efficiently managing inputs
and being good stewards of the environment.

Field Facts: Corn Replant Guide Southern USDuPont Pioneer
This guide can be applied to corn grain production in the southern U.S. for high, moderate and low expected yield levels for key hybrids grown in the south.
- The document discusses management options for northern BU corn rootworm (CRW) based on 2012 beetle and root ratings observations.
- It lists several Pioneer corn products with different insect protection traits including Optimum AcreMax 1, Optimum AcreMax, Optimum AcreMax Xtra, and Optimum AcreMax Xtreme.
- It provides brief descriptions of the insect protection technologies contained in each product including Herculex, Herculex I, and Agrisure RW traits.
Establishing a uniform alfalfa stand requires proper field preparation with a firm seedbed, planting the seed at the correct depth, and using the proper seeding rate. A successful stand also depends on addressing soil fertility needs, controlling weeds, and planting during the optimal windows in spring or late summer. The document provides guidelines for soil preparation, seeding, weed control, and the pros and cons of clear seeding versus using a nurse crop.
Pioneer Agronomy Sciences recommends planting corn at a depth of 1.5 to 2 inches for optimal emergence and root development. Studies showed corn planted at 3/4 inches took longer to emerge than corn planted at 2 inches, even in soils prone to crusting. Soil temperature was similar at 3/4 and 2 inch depths early in the season, so warmer soil wasn't responsible for the faster emergence of deeper planted corn. Establishing the nodal root system below the soil line through proper planting depth reduces risks and improves the corn plant's ability to withstand stress.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

2. Where is Our Corn At?
Data from Faribault, MN
This year has been one for the record books. We have
experienced tremendous ups and downs. Below is an
illustration of the ups and downs we have experienced
from mid-May thru August 16.
Planting: We started with a very wet planting season.
This put most corn in SE Minnesota in the ground either
mid-May or early June, outside of some pre-snow corn
and mid-June corn. Notice on the graph below, the first
two circles in that time frame. After each planting window,
we were faced with cold wet snaps which delayed emer-
gence of the corn crop. This is significant because it de-
layed emergence and put the crop behind its expected
stage based off of GDUs. Despite the challenges, plant
populations have been very good in most fields which
leaves the crop the opportunity for good yields.
Mid-Season: After the very difficult start, the rain stopped
and the heat was turned up as seen below. This heat
spell brought us to average GDU collection and also
brought many early fields to the pollination stage. Starting
July 23 however, the heat turned off. This was great for
tasseled corn to ensure great pollination, but this period
put the crop at great risk of not hitting black layer in many
fields. To put this cold snap in perspective, from July 23
through the last date collected below (August 16), it has
been 25 straight days of below average GDU collection
during what is normally the dog days of summer. This has
left us 116 GDUs off of average for the example of a May
15 planting date. Another key piece is that corn was
planted late, missing out on some early season heat. The
last third of August has begun to heat up again, and if we
carry that into September and avoid an early killing frost,
there is potential for some good yields in many fields.
Frost: Frost averages by location vary as much as a
week or two through much of southern MN. Also keep in
mind it takes a temp of 28°F for four hours to be a killing
frost in corn. This means for Faribault, MN in the example
below, there is a 25 percent chance of a killing frost by
Oct. 1. The link provided gives locations throughout Min-
nesota, so you can reference a point closer to home.

Yield information from monitors and GPS is an
extremely important tool that you can use to make deci-
sions in your business. However, it is only as accurate as
the calibration and taking time to do this will help elimi-
nate poor information later. Here are some tips to re-
member when looking at yield monitor calibration:
Clear memory card and back up previous year’s data
Calibrate multiple times throughout the growing sea-
son to ensure consistent data
Make sure loads are enough weight (3,000-6,000
pounds)
Make sure you have multiple loads at different
speeds (3.5, 4.5, 5 etc.)
Calibration loads should be in a uniform area of the
field, a good representation will improve accuracy
Differences in moisture and grain quality will require
a new calibration to be accurate
In a year with variability, taking time to calibrate will pay big
dividends!
Opportunities for Tillage
Primary tillage is most effective at lifting soil com-
pacted layers and producing an even shattering ef-
fect across the width of the tillage tool.
Appropriate levels of residue incorporation can be
accomplished which increases soil to residue contact
enhancing residue breakdown without layering resi-
due and causing seedling residue interactions (corn
on corn concern)
Residue sizing and corn root ball management can
be more effective with the use of corn head chop-
pers or stalk choppers combined with vertical tillage
tools prior to primary tillage.
Deep tillage will not ‘dry out your soils’.
Make every attempt to incorporate and reduce large
residue for next spring planting.
Calibrating Yield Monitors
The table above shows top selling Pioneer®
brand hy-
brids for SE Minnesota. The key takeaway is the Physi-
cal-CRM. A great example of this is Pioneer®
hybrid
P0533AM1™ brand. This product is marketed as a 105
day because of its late season harvest moisture even
though it black layers at a maturity of 101 day. This is a
huge bonus this year when reaching to black layer is the
critical factor. Also, it is important to note the Silk CRM.
The earlier the silking date, the less impact an early frost
would have on the hybrid. Finally, GDUs of when a hy-
brid will mature still varies by environment. Example:
Acres that had extended emergence periods due to satu-
rated conditions like this spring will be behind the “on
paper” black layer date.
