Phosphorus deficient plants appear as stunted, dark green plants erect leaves and stout stems which often develop orange, red or purplish discolouration... The need for phosphate fertiliser should be determined using soil, plant tissue testing and test strips... Copper sulfate applied to the soil at 10-20 kg/ha prior to or at planting will last a number of years...

While chickpeas are considered to have moderately high requirement for P, economic fertiliser responses to P are uncommon... The two exceptions are: soils with critically low P levels (below 6-8 mg P/kg, based on a Colwell test at 0-10cm) and no prior history of P fertiliser long fallow situations with low VAM levels (10 months or longer) even where soil levels are considered adequate... Some situations where N fertiliser may warrant consideration include: late plant situations where the crop can flower as quickly as 60 days, and rapid early growth is critical in achieving adequate height and sufficient biomass to support a reasonable grain yield...
