Abstract
The effect of adding organic manure to three soils with differing textures on changes in leaf water potential (LWP) and yield of barley (cv. Loyola) was investigated under controlled growth-chamber conditions. Cattle manure was applied to the soils in pots at rates equivalent to 0, 15, 25, 50 and 100 t ha-1. Plants were subjected to water stress by withholding water at three different stages of grwoth.
The results show that the addition of cattle manure significantly increased (p<-0.05) the organic carbon (OC) content of all the soils. LWP remained consistently high during the entire growing period in the control plants. As stress progressed, LWP in the stressed plants decreased. However, treatments with high OC contents had significantly higher LWP compared to those which had less. The former plants experienced less water stress than the latter.
Yields were higher in the control than stressed plants. Within the stressed plants however, treatments with high OC content had significantly higher yields. An effect of soil texture was also noted. Generally, the influence of manure application on LWP and yields were more pronounced in sand and loam than clay soils.
