Watergehalte in PERSPEKTIEF

Die eerste stap in die proses om ’n gewasbeskermingsproduk (GBP) toe te dien is om dit met water te verdun. Die rede hiervoor is om ’n laedosisproduk eweredig oor ’n gegewe oppervlakte te versprei. Water is relatief goedkoop en beskikbaar, daarom is dit die enigste praktiese oplosmiddel om GBP’s mee toe te dien. Water is […]

Precision agriculture in action: scaling on-farm experiments for profitability

The grain industry in South Africa is faced with several complex issues that threaten both profitability and production. Traditional farming methods are becoming less profitable due to rising input prices, erratic weather patterns, and growing demand to embrace sustainable practices. In an environment where commodity prices are volatile and a climate that is becoming more […]

The big five maize leaf diseases: identification and management

Maize is one of South Africa’s most important staple crops, forming the backbone of food security and livestock feed. However, its profitability and productivity are constantly threatened by leaf diseases that reduce yield and grain quality. These diseases, caused by fungi, bacteria, and viruses, can spread rapidly under favourable conditions, making early identification and timely […]

Amaranthus-soorte in SA: registrasie van onkruiddoders en onkruidweerstand

Amaranthus-soorte is welbekend as onkruid in gewasproduksie, maar het ook dikwels ekonomiese en sosiale waarde as verboude gewasse (graan of groente) of sierplante. Ongeveer 20 soorte het wêreldwyd onkruidstatus – met “onkruidstatus” word bedoel daardie soorte het ’n ernstige tot geringe skadelike effek op gewasproduksie. Die wetenskaplike groepnaam of genus, Amaranthus, sluit ongeveer 75 spesies […]

RWA-BIOTIPES kom hiér voor in 2025

Russiese koringluis (RWA) is ’n plaaginsek wat wêreldwyd voorkom in koringverbouingsgebiede. Hierdie insek het plaagstatus bereik as gevolg van die feit dat hy vinnig kan voortplant en versprei en geweldig aanpasbaar is teen enige druk wat in die omgewing voorkom. Die teling van koringkultivars met weerstand teen RWA is een van die beheermeganismes wat gebruik […]

Whole genome sequences promise new insight for barley industry

In the first few months of 2025, the CenGen team sequenced the whole genomes of two local malt barley varieties with more to follow – a first for South Africa. A locally conceived project to sequence a South African wheat variety was concluded in 2022, with all the sequencing performed abroad. This revealed the required […]

SEEDING RATE as a strategic agronomic decision

Barley yields are shaped not only by genetics and the environment but also by the key management decisions made before planting begins. One of the most important of these is seeding rate, a decision that affects both variable input costs and economic yield. Determining the correct seeding density is essential, as it influences how barley […]

Aanpasbaarheid van kultivars: benader risiko en opbrengspotensiaal strategies

Die keuse van die regte kultivar vir ’n spesifieke area is waarskynlik die belangrikste en terselfdertyd mees onderskatte bestuursbesluit wat jaarliks deur gewasprodusente geneem word. In ’n landbou-omgewing waar klimaatstoestande, grondtipes en siektedruk voortdurend verander, speel aanpasbaarheid ’n beduidende rol in die stabiliteit van opbrengste en die vermindering van risiko. Die keuse van die regte […]

NBTS IN WHEAT: regulatory and trade implications for SA

South Africa’s grain and oilseeds industry stands at a crossroads of global technological innovation and local trade regulations might create some trade barriers regarding food security of crucial crops like wheat. Agricultural technology globally is changing rapidly with new breeding techniques (NBTs) gaining traction internationally. South Africa’s uniquely cautious regulatory framework could cause the country […]
