Abstract
Screen house trials for the assessment of Neem-fortified cassava peels for control of plant-parasitic nematodes and yield improvement of sugarcane (Saccharum officinarum) were conducted in Moor plantation, Ibadan, Southwest Nigeria. Cassava peel powder (CPP) solely and in combination with Neem Leaf Powder (NLP) or Neem Seed Powder (NSD) at 100gCPP/10 Litre soil, 90gCPP+30gNSP/10 Litre soil, 80gCPP+20gNSP/10 Litre soil, 70gCPP+30gNSP/10 Litre of soil, 90gCPP+10gNLP/10 Litre soil, 80gCPP+20gNLP/10 Litre soil, 70gCPP+30gNLP/10 Litre soil were incorporated into potted naturally infested soil in the screen house, at 14 d before planting. All treatments significantly (p<0.05) reduced plant-parasitic nematode population. Soil treatment with Cassava Peel Powder in combination with Neem Leaf Powder at 70gCPP+30gNLP/10 Litre of soil recorded the most effective control for soil and root nematodes associated with sugarcane in the two screen house trials. The soil amendment also supported the good vegetative growth and yield of sugarcane, which is an indication of its capability to improve soil fertility.

Summary
Sugarcane (Saccharum officinarum,) is a large tropical grass that is grown commercially for sugar production [14]. Sugarcane is grown by thousands of local farmers in Nigeria [1] It is cultivated for its chewable pulps, which provide a source of income to peasant farmers and commercially for sugar production [18]. The soft chewing cane (Bekki variety) is usually grown as a continuous monoculture in many Nigerian farms, with not more than a few months interval between the removal of old ratoon crop and replanting of the field. This condition tends to favour the development of relatively large populations of nematode species [17] and reduction in crop yield
