Evaluation of the Residual Effect of Cattle Manure Combinations with Inorganic Fertilizer and Chemical Weed Control on the Sustainability

Abstract: The residual effect of fertility rates (cattle manure with inorganic fertilizer rates) was not significant on percent sand, silt and clay in 2004-2005, 2005-2006 and 2006-2007 trials. However In the three trials, the effect of residual fertility rates was significant on percent organic carbon, organic matter and cat ion exchange capacity (CEC) with the least value been obtained from the untreated control, followed by the separately applied inorganic and organic fertilizers. The application of main treatments had a significant residual effect on weed, sugarcane growth parameters and its stalk yield. Plots treated with combined application of cattle manure with inorganic fertilizer at all rates gave better performance of weeds, growth parameters and yield than plots treated with separate application of 10t/ha cattle manure and 120kgN/ha- 26kgP/ha-37kgK/ha inorganic fertilizer. The residual effect from the application of herbicides, hoe- weeding and the weedy check non- significant on weed control, sugarcane growth parameters and stalk yield.

The application of organic manures has the incorporated. Greater efficiency of manure is obtaine
