Picking the right paddocks for mungbeans
PULSE AUSTRALIA NORTHERN development agronomist Paul McIntosh is urging growers to plant mungbeans to ‘break up the sea of sorghum’ that he expects to be planted across northern NSW and southern Queensland in the 2018-19 summer. Strong demand for Australian mungbeans is expected to keep prices buoyant and attract new and experienced growers to plant the shiny green beans. Following an exceptionally dry winter, Mr McIntosh is urging growers and their agronomists to pay particular attention to paddock selection and to avoid planting mungbeans in paddocks were there have been recent applications of residual herbicides. “Mungbeans are very sensitive to residual herbicides, including the long-lasting Group I products such as Tordon and Lontrel, Group B sulfonylurea (SU) residues such as Glean, Logran and Ally, and Group C triazine residues such as atrazine,” he said. “Herbicide residues can pose a serious risk to mungbean crop safety, particularly after dry or cold winter paddock even is mungbean’s likely testing conditions. to history be for sensitivity.” worthwhile, residual is Knowing critical levels given and the considerations Other important are to assess the moisture and nutrient status of the intended mungbean paddocks. Mr McIntosh said mungbeans require a minimum of 75 mm of wet soil to support a wellgrown crop. “Mungbeans are a very quick crop and it is not usually a good idea to plant knowing that success is dependent on in-crop rain. Summer planting is usually the safest planting window for most growers and generally results in the best quality product for market,” he said. “The crop will also require good supplies of phosphorus, potassium, sulfur and zinc.” “If you plan to use growerretained seed, test for germination % and vigour before planting and make sure seed is replaced every three years,” he said. “I’d recommend buying AMAapproved seed to be assured of strong germination and vigour, along with reduced risk of seed-borne disease.
