The NSW Department of Primary Industries and Regional Development (NSW DPIRD) has launched a new sorghum production guide aimed at enhancing the yield and quality of sorghum crops in northern New South Wales. This initiative results from a year-long research partnership with the Grains Research and Development Corporation (GRDC), focused on improving crop production reliability and increasing water use efficiency.
Grain sorghum is the primary summer crop in the state, with the majority of production originating from northern NSW. Traditionally, sorghum has been cultivated as a feed source for the domestic livestock industry; however, its use in human consumption is on the rise.
Tailored Guidance for Diverse Growing Regions
According to Loretta Serafin, a Northern Cropping Systems Research Officer based in Tamworth, the guide offers valuable insights for the distinct growing regions of the Liverpool Plains and North West NSW. “While the Liverpool Plains has a long-standing reputation for reliable and profitable sorghum production, the North West has a comparatively shorter history, particularly west of the Newell Highway,” Serafin explained.
The North West region is characterized by high summer temperatures, lower and more variable rainfall, and predominantly winter crop rotations. These climatic conditions have historically deterred growers from embracing summer crops. However, above-average rainfall in recent years has prompted a shift, encouraging more producers to incorporate sorghum into their rotations.
Research-Driven Solutions for Growers
Jon Baird, the GRDC Grower Relations Manager who oversaw the project, emphasized the significance of the research investment in addressing specific challenges faced by grain growers in northwestern NSW. “Many growers experienced issues with colder soils when planting early summer crops, which delayed plant development,” Baird noted. “Additionally, concerns arose from harvesting crops with lower protein levels (9% or less) and diminished yields.”
The guide aims to equip these growers with the knowledge and confidence needed to manage early sown sorghum effectively. It includes recommendations for strategic fertilizer use, row spacing, and plant populations tailored to seasonal conditions.
“Achieving profitability in sorghum is primarily linked to grain yield, as higher protein levels do not necessarily command a premium price. Hence, our focus remains on maximizing yields,” Serafin stated. With the growing market for human consumption, there is potential for higher premiums on better grain quality. Currently, grain protein levels below 9% are considered yield-limiting, indicating insufficient nitrogen application.
The sorghum production guide provides comprehensive advice on optimal soil and water conditions, along with the best planting timings. It compiles the latest research findings from various trials conducted across northern NSW, highlighting critical insights into row spacing, plant population, and crop nutrition.
This document builds upon the department’s extensive suite of information guides designed to assist growers and agronomists in making informed decisions regarding crop management. The latest version of the NSW DPIRD sorghum production guide is available for download as a PDF, further supporting the agricultural community in their efforts to enhance sorghum production.
