Inoculants by Crop - JumpStart - Chickpea
JumpStart, the phosphate inoculant, contains the naturally occurring soil fungus Penicillium bilaii, discovered by Agriculture and Agri-Food Canada. It colonizes plant roots and makes the ‘fixed’ mineral forms of less available soil phosphate immediately available for crop use.
JumpStart promotes greater phosphate use efficiency, which results in quick emergence, early vigour, greater stress tolerance, and more even maturity. JumpStart delivers a safe method of supplying phosphate to growing plants and reduces the need to seed-place high rates of fertilizer phosphate with sensitive seed like canola, pea and lentil.
Chickpeas are normally considered to have similar fertility requirements as pea and lentil crops, and it is a well known fact that pulse crops require phosphorus to support healthy growth, hasten maturity and support nitrogen fixation.
Nitrogen: Chickpeas inoculated with a nitrogen inoculant should not require nitrogen fertilizer as they can fix 60-80% of their nitrogen needs. The other 20-40% will usually be made available through nitrogen present in the soil and by mineralization throughout the growing season but special care is still required to ensure adequate phosphate fertility.
Phosphate: Chickpeas are very sensitive to seed-placed fertilizer. Under good moisture conditions only 15-20 lb/ac of actual phosphate can be safely seed-placed, assuming good to excellent soil moisture, a one inch spread to the fertilizer and a 9 inch row spacing. Inoculating with the phosphate inoculant, JumpStart can be a very easy and effective way to supply additional phosphate. Using JumpStart gives your crop early access to phosphate for quick emergence, early plant vigour, larger root system and greater yields.
310 trials over the 18 years prove the performance of JumpStart on a wide variety of crops.

¹Net returns were calculated using 5 year average (2000-2004) US commodity prices for crops and fertilizer less the 2006 suggested retail price for JumpStart.
²Average yield response applied to a target yield of 150 bu/ac to calculate net return/acre on corn.
3Total and average of wheat, winter wheat, canola and pea/lentil trials.
495% confidence limit is $1.31 per acre. This means the net return for all crops will range between $4.20 and $8.63 per acre 19 times out of 20.
5Average P fertilizer difference is 15.1 lbs P2O5 per acre on the no JumpStart control strips.
JumpStart Application
JumpStart is sold as a wettable powder that is mixed into water and applied to the seed prior to seeding.
