Abstract

Variations in penetrometer soil resistance (PSR) as a result of drought stress at different growth phases, and it's relationship to pod production and yield of peanut (Arachis hypogaea L. cv Robut 33-1) were evaluated under field conditions during post-rainy season. Pod number per plant decreased linearly with increase in PSR. Final yield, however, was not directly related to the mean seasonal PSR since PSR, Per se, does not reduce yield.
