    Episode 2 of 23: Nematodes in Soybean production

    Episode 2 of 23: Nematodes in soybean production In this episode of ‘We’ve bean around the block’, we catch up with world renowned nematologist Prof Driekie Fourie and discuss the nematodes that are problematic to soybean production in South Africa. The root knot nematodes (Meloidogyne spp.) are considered the biggest nematode problem in South Africa, but the lesion nematodes (Pratylenchus spp.) are very widely distributed across all the soybean production areas in the country. The cyst nematode (Heterodera) is not currently found in the country, but Prof Fourie sounded the warning that it had recently been detected in neighbouring Zambia. Control of nematode numbers in our soils and population dynamics are discussed and the conclusion is drawn that an integrated strategy involving poor host plant species in rotation, resistant cultivars, cultural practices and new era chemical active ingredients are required to build soil health and suppress nematode populations in our soybean production.

    Episode 1 of 23: Cane in pain

    Episode 1 of 23 Cane in pain In this episode of ‘We’ve bean around the block’, we re-visit the topic of dry beans in rotation with sugarcane. This episode follows a previous podcast (Episode 5 of 21) with advanced thinking of how to incorporate beans into a rotation with sugarcane. Host Antony Jarvie discusses rotation ideas and practicalities with forward thinking cane farmer, Deon Schröder. The problem with incorporating dry beans into a sugarcane rotation is always going to be the herbicide residues from the cane component. The shrinking crushing capacity in the industry is forcing a reduction in sugarcane output, which for the first time, provides an incentive for a multi-year and or a multi-crop rotation strategy. The idea to bring in glyphosate tolerant hybrid maize as a first rotation crop and then to follow this with beans in the second season, as a way to avoid the effects of sugarcane herbicide residues, is discussed at length.  The practical aspects of turning a sugarcane operation into a more diverse farming unit is also discussed. The podcast was recorded with Deon Schröder, but it followed a workshop discussion that included input from Dave Wilkinson, Shaun Carroll, Marcel Ortmann and Andrew Braithwaite.

    Adopting Success: Zamukele

    Episode 6 of 22 Adopting Success: Zamukele In this episode of ‘We’ve bean around the block’, host Antony Jarvie discusses the Zamukele project with Success Mdluli of the Schoeman Group. Zamukele is a Zulu word that means ‘adopt’, and it is a platform that the Schoeman Group have developed to adopt small-scale farmers into their canning bean enterprise. After an initial screening process, successful applicants to the scheme are assisted with agronomic support, seed and fertilizer inputs to begin their small white canning bean production. Once the harvested crop is delivered back to the Schoeman Group, the costs of the inputs are paid off and the profit is returned to the farmer. It is in essence a private sector initiative to assist small-scale farmers to access finance for their production. Without land ownership, small-scale farmers have no access to the formal banking sector for production loans. This remains a hurdle that the government has been unable to address adequately. Agribusinesses wishing to support the Schoeman Group by carrying some of the risk related to inputs in this project, can get in contact with Success Mdluli via email (success@witklip.co.za) for details.

    Episode 5 of 22: Agronomic strategies for following a wet season

    Episode 5 of 22 Agronomic strategies for following a wet season In this episode of ‘We’ve bean around the block’, host Antony Jarvie and experienced agronomist Grant Pringle explore the prospects for the 2022/23 summer cropping season.  In this podcast, the agronomic strategies that should be considered are explored in a crop agnostic fashion. The very wet preceding two seasons, which by many accounts has been largely positive for agriculture in South Africa, now lays a foundation for increased crop disease risks. The need for rotation is discussed, as well as increasing the length of the rotation and the obligation to protect the most vulnerable crop within the rotation. Cultivar choices which emphasize yield stability are important, as is the need to prioritise disease resistance. Current disruptions to global supply chains could mean that important inputs like fungicides may not be freely available, which accentuates the need for comprehensive defensive trait packages in the cultivar choices made for the season. Seed treatment considerations are discussed, as is the need for certified or disease-free seed in crops such as dry beans. Lastly, the call for patience at planting time is made to ensure that the soil conditions are ideal at planting. While this podcast assesses agronomic strategies for the next season, Wandile Sihlobo the highly acclaimed agricultural economist, has captured the economic drivers that have shaped the agricultural outlook for the 2022/23 season in his new podcast channel. This is well worthwhile listening to in conjunction with this episode.

    Episode 4 of 22: Nitrogen Fixation

    Episode 4 of 22: Nitrogen fixation In this episode of ‘We’ve bean around the block’, host Antony Jarvie discusses nitrogen fixation with UKZN’s Professor Mark Laing. The discussion is centred around nitrogen fixation in soybeans, but it broadens into a discussion that covers legumes and non-legume crops. The fragile Bradyrhizobium japonicum used in soybean production is not indigenous to South African soils, so it needs to be inoculated at planting. The importance of out-competing other microbes and wild strains of rhizobia is discussed, as is the need to inundate the rhizosphere with the desired highly efficient N-fixing strains. The most widely used rhizobia strain (WB74) has been deployed for more than 20 years, and current soybean cultivar selection has been optimised on this strain. With climate change, soil environment conditions are changing rapidly, and there was much debate around the requirement for strain improvement to meet these changes. There are allied microbes that we should be developing alongside the rhizobia to buffer their exposure to harsh conditions. Professor Laing went on to introduce the topic of nitrogen fixation by free-living microbes. The examples given included N-fixation in sugar cane, cereals such as wheat and maize and in forestry. His own ground-breaking research is poised to commercialize a N-fixing Bacillus species, which could contribute towards reducing agriculture’s reliance on fertilizer nitrogen.

    Episode 3 of 22: Grant us technology, in abundance

    Episode 3 of 22: Grant us technology, in abundance Peering down the Corteva soybean pipeline is a bit like overhearing a farmers’ prayers… grant us technology, in abundance. In this episode of ‘We’ve bean around the block’, host Antony Jarvie brings you both Grant and technology. The guest for this episode is Pannar agronomist Grant Pringle, who shepherds the discussion through the soybean technology on its way to the South African producer through the Corteva pipeline. The new trait package is called Conkesta E3, abbreviated to CE3, which includes three herbicide resistant genes (2.4D, glyphosate & glufosinate) stacked with two Bt proteins (Cry1Ac, Cry1F) for lepidopteran insect control. There is a configuration of this package just called E3, which only includes the three herbicide resistances that may be used as a stand-alone trait package or as refuge for the CE3. Both E3 and CE3 are designed to be used with the Enlist herbicide system. Enlist is the new choline formulation of the herbicide 2.4D, which is used in a tank mix with either glyphosate or glufosinate for exceptional weed control.  This new trait development will change soybean production in South Africa for good.

    Episode 2 of 22: Seedling disorders

    Episode 2 of 22: Seedling disorders In this episode of ‘We’ve bean around the block’ host Antony Jarvie talks to product agronomist Grant Pringle about seedling disorders in dry beans. Often poor germination and emergence are blamed on seed quality, but as Grant explains, there are a host of reasons why the germination percentage on the seed bag may not align with what is experienced in field. The cool wet conditions faced this season has resulted in poor germination, un-even emergence, and variable maturation. The effects of moisture, temperature, compaction are discussed and expanded to their interaction with fertilizer, herbicides and soil pathogens. The major soil-borne pathogens that are mentioned include Pythium, Rhizoctonia and Fusarium.

    Episode 1 of 22: 2021 year in review

    Episode 1 of 22: 2021 year in review Questions from the mail bag ‘We’ve bean around the block’ podcast host Antony Jarvie invites an avid listener, Colin Prince, to critically review the channel and to assist with listener questions. Colin, who is a seasoned enthusiast of podcasts and claims to have listened to all the WBATB episodes, discusses the pros and cons of show length, frequency and seasonality. He then goes on to pose questions raised by listeners. The End Point Royalty discussed in Episode 7 of 21 raised two important questions. Should farmers who buy seed still be liable for the EPR, and is a differential royalty rate for different cultivars a possibility? Episode 5 of 21 featured the investigation of rotating sugar cane with dry beans. This episode attracted the question of how would one get started with such a rotation? A question that followed Episode 11 of 21 on the insect pests of soybean was centered around new insect resistance technologies. Would Bt soybeans be as popular as Bt maize, and when could we expect to see this technology in the field? The last question was about show content for 2022.
