Abstract
The properties of palm oil sludge cake indicated that it could be beneficial for promoting growth of immature oil palm rubber and cocoa in the field. Application of 1 to 2 kg of palm oil sludge cake into the planting hole was beneficial for both oil palm and rubber seedlings. Higher rates of over 3 kg for rubber and 6 kg for oil palms appeared to be detrimental to growth. For cocoa the best rates were between 0.25 and 0.5 kg per planting hole. The rubber buddings and cocoa seedlings were scorched and defoliated when the planting holes were filled with sludge cake. Palm oil sludge cake was effective as a source of N for young oil palms rubber buddings and rubber ground nursery. When applied to the soil surface it appeared to have little effect on young cocoa growing under leguminous shade trees. In rubber the effect was probably due to the extra nutrients the treatments with sludge cake contributed in addition to the normal routine manuring. Rates of 300 g per plant for ground nurseries and 2 kg for buddings appeared to be optimum and higher rates appeared to reduce growth. In oil palm sludge cake treatments had comparable growth with the addition of inorganic N. These manured treatments were significantly better growth than the control treatment without any N fertilizer. Since the effect of sludge cake application was mainly due to its nutrient effect its use would probably be limited to similar poor areas where nutrition was a problem or to areas where frequent fertilizer application with inorganic fertilizers was necessary
