Results tell chickpea establishment story


Australia
June 14, 2012

Chickpea seed tests from the 2010 harvest have shed light on establishment problems in last season’s crops.

Dr Kevin Moore, NSW Department of Primary Industries (NSW DPI) special plant pathologist (pulses and oilseeds), Tamworth, NSW says many 2011 chickpea crops had problems with establishment and seedling disease.

“More than half the seed lots were infected with Botrytis and 89 per cent were colonised by other fungi,” Dr Moore said.

“Fungal infection, weathering of seed and inadequate seed treatment were the major causes of poor emergence and seedling blight.

“Growers who use correctly treated seed in 2012 are more likely to have profitable chickpea crops.”

Dr Moore presented the findings to growers and agronomists at the recent round of Grains Research and Development Corporation (GRDC) Updates and said the work highlighted the importance of proper seed treatment.

“The 2010 chickpea season in the GRDC northern grains region (Dubbo north) was the wettest on record with substantial rain falling during grain development and maturity,” he said.

“Diseases were common, crops lodged and grain was severely weather damaged.”

He presented the results to help growers and agronomists understand better why 2011 crops planted with seed harvested from the 2010 season encountered establishment problems.

Eighty one seed lots from north central NSW, northern NSW and southern Queensland were processed at Tamworth Agricultural Institute. Each was subjected to emergence, germination and pathology tests.

GRDC invests in more profitable chickpea production via research projects on disease screening and management, pest management and agronomy.
