Sojaflits 1 / Soybean News Flash 1
PROTEIN RESEARCH FOUNDATION — 2021-07-15
Evalueer die pas afgelope seisoen op beide die sojaboonland en die land waarop die komende seisoen sojabone geplant gaan word. Waarna veral opgelet behoort te word sluit in:
swak kolle, stel vas waarom dit swak is en hoe kan dit opgelos word;
watter siektes, peste en plae het voorgekom en hoe kan die bestryding daarvan verbeter word;
kyk na die onkruidspektrum en hoe dit beter beheer kan word;
neem die wagperiode van onkruiddoders in ag voordat sojabone aan 'n bepaalde land toegewys word.
Neem verteenwoordigende grond monsters en opbrengskaarte en maak seker dat die resultate vroeg genoeg benut kan word om regstellings, indien enige, betyds te maak. Hierdie inligting sal ook die tydige aankoop van kunsmis en kalk bevorder. Neem in ag dat 1 ton sojaboon graan tot soveel as 100kg N, 8kg P en 40kg K en 6kg S verwyder met 'n water pH wat verkieslik bokant 6 moet wees.
Cultivarkeuses moet gemaak word om saad betyds te bestel.
Kies allereers die volwassenheidsgroep waaruit die cultivars moet kom en daarna die bepaalde stel cultivars. Hoe koeler die gebied hoe vinniger sal die verkose cultivar moet wees om die eerste ryp te ontsnap, of om in te pas by 'n laat aanplanting. Volwassenheidsgroepe val tussen 4 en 7 met 4 die kortste groeiers en 7 vir 'n warm lang produksieseisoen.
Kies meer as een cultivar met verskillende groeilengtes. Nie alleen sal dit die risiko versprei nie maar uit 'n praktiese oogpunt sal dit die stroopdatum versprei wat die druk op stroperaanwending verlig.
Maak seker van spesifieke cultivareienskappe soos siekteverdraagsaamheid, peulhoogte (vir maklike stroopbaarheid) en veral aanbevole plantestand.
Saadgrootte sal bepaal hoeveel saad per hektaar benodig word by 'n plantestand wat mag wissel tussen 250 000-400 000 plante per hektaar.
Die keuse van 'n spesifieke cultivar vir 'n bepaalde gebied behoort gebaseer te word op soveel bronne van inligting as wat bekom kan word. Die Nasionale Cultivarproewe wat deur die LNR uitgevoer word is 'n goeie bron van basiese inligting, vul dit aan deur maatskappy inligting en studiegroepproewe.
Selekteer die beste land en pas wisselbou toe
Sojabone behoort verkieslik op 'n diep goedgedreineerde grond met goeie waterhouvermoë geplant te word. Sojabone kan goed produseer op kleigronde maar kan ewe eens op sandgronde verbou word alhoewel knopwortelaalwurm 'n probleem mag skep.
Beplan die gewasopvolging. Onthou wisselbou is 'n stelsel nie 'n toevallige besluit nie. Neem veral in ag dat mielies wat op sojabone volg in die meeste gevalle meer as 10 persent opbrengsverhoging (op mielies) toon.
Wisselbou kan ook met koring suksesvol gedoen word.
Sou 'n produsent oorweeg om na bewaringsbewerking oor te skakel sal hy nou reeds alle aspekte in orde moet kry vir die verandering.
Bemesting optimiseer veral fosfaat;
Beperkende lae ophef;
Verseker dat werktuie geskik is vir die nuwe stelsel, veral stoppelplanter(s) en spuit toerusting;
Moenie oorskakel na bewaringsbewerking as stoppel op die land minder as 30 persent van die landoppervlakte bedek nie.
HAVE A LOOK AT THESE VIDEOS BY WESSEL VAN WYK ON OUR WEBSITE
Evaluate the past production season on both the soybean land and on the land where soybeans are to be planted in the coming season. Be on the lookout for aspects such as:
weak patches – determine why the patches are weak and how the problem can be resolved;
which diseases and pests were problematic, and how can control be improved;
the weed spectrum during the past season, and how can control be improved;
take the waiting period for herbicides into consideration before planting soybeans in a specific area.
Take representative soil samples and yield charts and ensure that the results are utilised timeously to effect corrective steps, if required. This information will also promote the timeous acquisition of fertiliser and lime. Take into account that a yield of 1 ton soybeans removes as much as 100kg N, 8kg P, 40kg K and 6kg S from the land. Water pH should preferably be ≥6.
Cultivar choices should be made so that seed can be ordered well on time:
First select the appropriate maturity group before deciding on specific cultivars. Fast growers should be selected in order to evade the first frosts in the cooler areas, or to fit in with a late planting. Maturity groups range from 4 to 7, with 4 being the shortest growing period and 7 for a long, warm production season.
Choose more than one cultivar with different growing periods. This will not only spread the risk, but will also alleviate pressure at harvesting time as harvesting dates will be well spaced.
Check cultivar characteristics such as disease tolerance, pod height (for easy harvesting) and take note of recommended plant density.
Seed size (hundred seed mass) will determine the quantity of seed required per hectare, with a planting density that may vary between 250 000 and 400 000 plants per hectare.
The choice of a specific cultivar for a specific area should be based on as many sources of information as possible. The results of the ARC's National Cultivar Trials are a good basic source of information. These results can be supplemented with information from seed companies and study groups.
Select the best land available and apply crop rotation:
It is preferable to plant soybeans on deep, well-drained soil with good water retention capacity. Soybeans can produce well on clay soils, and can also be planted in sandy soils although root knot nematodes may cause problems.
Plan the crop rotation system. Keep in mind that crop rotation is a system and not an accidental decision, and that a soybean:maize crop rotation system in most instances result in a 10% yield increase.
A crop rotation system with wheat can also be successful.
Corrective measures need to be taken before switching to conservation agriculture. These include:
correction of pH;
optimising fertilisation specifically phosphate;
address soil compaction issues;
making sure implements and tools are suitable for use in conservation agriculture practices, especially planters and spray equipment;
do not switch to conservation agriculture if stubble on the land covers less than 30% of the soil surface.
Veels geluk aan die vier wenners van die 2020 Canola Opbrengskompetisie: Sakkie Rust, Melt van der Westhuizen, Franco le Roux en Johannes Beukes.
Indigenous Maize: Who Owns the Rights to Mexico's 'Wonder' Plant?
PROTEIN RESEARCH FOUNDATION — 2020-11-20
A nitrogen-fixing maize grown in an indigenous region of Mexico has the ability to fertilize itself, recent research shows. Now, as a global company and U.S. scientists work to replicate this trait in other corn varieties, will the villages where the maize originated share fairly in the profits?
Screening soybean genotypes for high temperature tolerance by in vitro pollen germination, pollen tube length, reproductive efficiency and seed yield
PROTEIN RESEARCH FOUNDATION — 2020-11-18
High temperature stress is a major environmental stress and there are limited studies elucidating the impact of high day and night time temperature on reproductive processes in soybean. Twelve soybean genotypes were grown at day/night temperatures of 30/22, 34/24, 38/26 and 42/28°C with an average temperature of 26, 29, 32 and 35°C, respectively under green-house conditions.
Consistent negative response of US crops to high temperatures in observations and crop models
PROTEIN RESEARCH FOUNDATION — 2020-11-16
High temperatures are detrimental to crop yields and could lead to global warming-driven reductions in agricultural productivity. To assess future threats, the majority of studies used process-based crop models, but their ability to represent effects of high temperature has been questioned. Here we show that an ensemble of nine crop models reproduces the observed average temperature responses of US maize, soybean and wheat yields.
Auburn University entomologists have discovered a wasp that may help out soybean producers and other farmers in the Southeast. Though only about the size of a pinhead, the newly detected wasp, Ooencyrtus nezarae, can do plenty of damage to the kudzu bug, a quarter-inch-long invasive pest to soybeans and other legume crops. Left unchecked, kudzu bugs can reduce crop yield by half.
Innovative approach to breeding could mean higher yields and better crops
PROTEIN RESEARCH FOUNDATION — 2020-11-11
Agricultural Research Service (ARS) scientists in Albany, California, have found a way to streamline the process that scientists use to insert multiple genes into a crop plant, developing a reliable method that will make it easier to breed a variety of crops with vastly improved traits.
Soybean bioactive peptides and their functional properties
PROTEIN RESEARCH FOUNDATION — 2020-11-09
Soy consumption has been associated with many potential health benefits in reducing chronic diseases such as obesity, cardiovascular disease, insulin-resistance/type II diabetes, certain type of cancers, and immune disorders. These physiological functions have been attributed to soy proteins either as intact soy protein or more commonly as functional or bioactive peptides derived from soybean processing.
Researcher developing new industrial uses for wax made from soybean oil
PROTEIN RESEARCH FOUNDATION — 2020-11-06
Petroleum-based paraffin wax commonly coats cardboard and all sorts of other products to improve durability and water resistance, but it can't be recycled and may adversely affect human health. So researchers at Iowa State University are developing wax from soybean oil that would share many properties of paraffin wax but would also be biodegradable.
ePaint is a company located in East Falmouth, Massachusetts, that has received support from the NIFA's Small Business Innovation Research program (SBIR). "Biofouling" is where marine organisms attach to hard surfaces, which is a major problem for marine aquaculture. A common solution is to use paint that contains copper since the copper will inhibit attachment to hard surfaces.
Boosting soybean yields begins by understanding the needs of the soybean plant and its environment, then adopting the best agronomic practices and technology to optimize yield. Innovation is important, but it won't do any good unless farmers apply basic management practices.
Farmers balance weed management, crop performance and sustainability on their farm. Farmers are moving toward no-till practices, but many still rely on tillage to control weeds. Thinking ahead to the new planting season, it's important to know which option is best for your farm.
As planters and farms grow, some farmers are moving away from narrow rows, but research shows return per acre can be maximized by planting rows narrower than 30 inches. That was one conclusion of a recent soy checkoff-funded study that found row spacing and other agronomic decisions can improve yield more than any spread or spray.
Six things farmers should know about seed treatments
PROTEIN RESEARCH FOUNDATION — 2020-10-23
Many farmers may be questioning whether their soybeans need a fungicide seed treatment this planting season. But that depends on many factors – from weather and planting date to drainage and seed costs. And if conditions or field history do not dictate the use of a fungicide seed treatment, then it may not be the best option for you.
Study builds on existing data to confirm strategic priorities
PROTEIN RESEARCH FOUNDATION — 2020-10-21
Researchers from several Midwestern universities collaborated on a project, funded by the soy checkoff, clarifying several issues ranging from the regional protein concentration of soybeans to the relationship between protein concentration and yield.
Andy Michel, Field Crops Entomologist, Ohio State University writes:
My laboratory at Ohio State focuses on understanding how soybean aphids are able to overcome aphid resistance in soybean. Through this research, we hope to develop strategies that prevent the spread and increase of aphids capable of breaking aphid resistance. In the course of generating DNA sequences with projects funded by The Ohio Soybean Council and The North Central Soybean Research Program (as well as USDA-NIFA and the Center for Applied Plant Sciences at OSU), we were able to sequence the entire soybean aphid genome.
Catch this thief early by learning which environmental conditions the disease likes and which management practices it hates. Did you know that soybean sudden death syndrome (SDS) is now among the top yield-robbing diseases in the U.S.? If you have fields with a history of SDS, learn about how to manage the disease and prepare for if it hits your fields next year.
Herbicide-resistance weed control through combine maintenance
PROTEIN RESEARCH FOUNDATION — 2020-10-14
Weed control isn't normally a priority during harvest, but combines are the ideal vehicle to spread weed seeds across a field or carry them to the next. Herbicide-resistant weeds are an ever-growing issue, and prevention of the spread of those plants is a year-around duty.
Improve sustainability all year long: Ten production practices that boost sustainability
PROTEIN RESEARCH FOUNDATION — 2020-10-09
U.S. soybean farmers are committed to continuous improvement – making sure the land they farm now is prosperous for years to come. Sustainability is a year-round effort; start your sustainability journey with these 10 sustainable practices.
