Abstract
The effect of triple superphosphate (TSP) and polyvinyl alcohol (PVA) application on crust strength, soil physical properties and seedling emergence of pearl millet (Pennisetum typhoides (Birm. f.) Stapf & Hubbard) was studied on a sandy loam soil. Crust strength measured by cone and pocket penetrometers in-situ and by modulus of rupture in the laboratory correlated significantly. Final seedling emergence percentage and rate of emergence increased significantly under TSP at 800 kg ha-1 P and PVA at 0.1% (wt/wt) treatments. Soil physical properties viz., water stable aggregates > 0.25 mm, dispersion percentage and modulus of rupture of soil governed the final seedling emergence of pearl-millet, in addition to the crust strength. These soil properties can be used for evaluation of crust strength and final seedling emergence of pearl millet
