Effect of Sweet Sorghum Bagasse Compost on Sweet Sorghum Productivity in Pots

The main purpose of this work is to study the effect of sweet sorghum bagasse compost application on biomass production of sweet sorghum (Sorghum bicolor (L.) Moench cv Dale). Biomass production was studied in terms of dry matter and stalk sugar content, at the end of the crop cycle. The addition of compost to soil produced significant increases on sorghum productivity with regard to the control. Best results have been achieved with the composts obtained from a sweet sorghum bagasse and pig manure mixture (30t/ha). In this case, the aerial dry biomass increments with regard to the mineral fertilizer treatment was 37%, where the irrigation was 2/3 of the available water.
