Abiotic and biotic factors were found to be related to growth rates of a cheatgrass sward using stepwise regression analyses. Soil temperature and plant tissue nitrogen showed a strong relation with growth rates from initiation of growth to peak production. After peak production, soil temperature was related to declining growth rates. Water stored in the soil profile had a weak relationship with growth rates and plant growth was completed before soil water became limiting. Equations were developed using soil temperature, nitrogen content of plant tissues, and live herbage production to estimate future production of cheatgrass.
