Topic: Weed Science And Sustainable Agriculture
Weeds are one of the major problems in crop production around the world. In most agroecosystems, weed control largely depends on chemical and mechanical practices that are very expensive and hazardous to the environment and, consequently, unsustainable.
Therefore, the focus my research is on the development of a sustainable agricultural cropping systems that require fewer production inputs that will serve as an alternative method to chemical and mechanical weed control in crop production.

Productivity of 20 Sweetpotato (Ipomoea batatas[L.]Lam) Cultivars In Ibadan,Nigeria.
Sweepotato (Ipomoea batatas[L.] Lam) is a dicotyledonous plant that belongs to the family Convovulaceae. It is the only specie in the family comprising about 1000 species, which is of economic value as food. Its large, starchy,sweet tasting tuberous roots are an important root vegetable(Purseglove,1991).
Sweetpotato ranks seventh in terms of production after wheat, rice, maize, potato,barley and cassava(CIP, 2008). it is grown on about 9 million hectares, yielding 124 million tonnes with an average yield of about 13.7t/ha(FAOSTAT, 2008). About 100 developing countries in Asia and Africa grow sweetpotato, with China as the largest producer (FAOSTAT,2010)
The production, marketing and utilization of sweetpotato have expanded in the last decade to almost all ecological zones in Nigeria (NRCRI, 2009). According to Akoroda et al., (2007), a total of 516,000ha of sweetpotato is cultivated in Nigeria, producing 2,516,000 tonnes of fresh tuberous root yield obtained in 4 to 5 months with an average yield of 4,875kg/ha
Several sweetpotato cultivars are maintained by national gene banks all over the world, only a few, just up to two in some cases, predominates the sweetpotato growing areas in each major sweetpotao producing country. The choice of cultivars to grow appears to depend largely on yield and how the produced is utilized
The objective of this study is therefore to evaluate the productivity of 20 sweetpotato cultivars under Ibadan conditions and recommend cultivars with better field performance.
