Abstract

Dairy plant wastewater can be utilized for irrigation of pastures. Napier Grass (Pennisetum purpureum Schumach.) is one of the pastures main fodder for dairy industry. The effect of using dairy plant wastewater on selected chemical properties of soil and growth of Napier grass were characterized. The growth of Napier grass was observed using wastewater for irrigation and was compared to other sources of irrigation: rainfed and raw water. A complete random design was used and it was statistically analyzed using analysis of variance (ANOVA) and least significant difference (LSD) for comparison of treatments. The NPK of soil before and after application of wastewater was compared. It was found that the wastewater contained salts that is within the acceptable limits for irrigation purposes. The wastewater was classified as Class D which may be used for agriculture, irrigation, livestock watering and others based on DAO 35. Analysis of the soil where Napier grass was planted revealed a texture of sandy loam. Using wastewater as irrigation of Napier grass, it was found through ANOVA that there is a significant difference on the height, basal circumference and dry matter yield while the means of height and dry matter yield between raw water and wastewater treatments were same using LSD. The nutrients from wastewater that may increase growth of Napier grass was not utilized maybe because the losses in the soil and other mechanisms.
