Abstract :

A study was conducted at Metahara Sugar Estate in Ethiopia with the objectives to determine the optimum rates of nitrogen and compost for sugarcane production, and the effect of compost on soil chemical properties. Four levels of nitrogen (0, 46, 92, and 38 Kg /ha) and five levels of compost (0, 5, 10, 15, and 20 ton/ha) were combined in factorial arrangement. The experiment as laid out in randomized complete block design with three replications. It was conducted on clay soils (Haplic Cambisols). Soil mples were taken before and after treatment application, and  analyzed  for  pH  (1:2.5),  ECe,  organic  carbon,  total  N, available  P,  and  available  K.  All  the  cultural  practices  were executed as per the estate’s practice. Analysis of the soil indicated that except for pH value, all the salient soil properties including ECe, organic carbon, total nitrogen, available P, and available Kere slightly increased ue  to  compost  application.  Analysis  of  variance  indicated  that  interaction  effect  between  nitrogen  and  compost  was gnificant (p<0.05) on stalk girth, stalk weight, cane yield, and sugar yield. Highest cane and sugar yields were btained when 46 Kg N/ha applied with 15 ton of compost/ha. Net benefit to cost ratio was also found to be the highest, 1.12, for this combination. Therefore, 46 Kg N/ha with 15 ton of compost/ha is recommended for clay soils (Haplic Cambisols)
