Details of Innovation	Yam is the carbohydrate-rich staple food of sub-Saharan Africa. Nigeria supplies about 70% of the world's yam. Ethno-centric attachments to yam are high in Nigeria particularly in the southeast agro-ecological zone. Most of the ceremonial yams (large tubers weighing 5 to 10 kg.) are produced in the lowland and alluvial flood plains of the forest and savannah. In Anam, a flood prone area of Anambra state, yam is the principal crop. It is cultivated without the use of inorganic fertilizers. Harvesting starts as early as April-May in order to avoid damage caused by floods. Thus most of the yams are harvested at a stage when they are physiologically immature and contain about 70-80% moisture. Because of the high moisture content they are prone to rot. To deal with this problem, the Anam farmers have developed a suitable method of storage referred to as the Ceilsmo method. Not only does the method prevent rotting but it also enhances the breaking of dormancy. The Ceilsmo method consists of spreading out the freshly harvested tubers on the ceiling of a kitchen or a living room where cooking is done with firewood. The smoke from the fire-place serves as a fumigant. The fire also increases the room temperature and relative humidity near the ceiling where the yams are stored. It is hypothesized that this increases the rate of biochemical reactions and hastens curing of the yams. Seed yams can be stored in this way for three to four months.(Abridged version of article sent by G. O.

Other Community Practices	Weed control is one of the most important objectives of cultural operations. Following proper cultural operations is more than half the weed control method envisaged on a farm, which directly includes a healthy growth of crops and indirectly it maintains a crop environment that is detrimental to weeds. Vedprakash et al. (2000) observed that bulb yield of onion showed better performance under herbicides combined with hand weeding treatment over herbicides alone owing to effective control of weed through herbicides during initial stage and later on by hand weeding. Higher weed control was obtained with manual weeding throughout the crop season in onion (Marwat et al., 2005, Ghadage et al., 2006 and Zubiar et al., 2009). Babu (2008) reported that weed free check treatments registered higher cured rhizome yield (7.08 t ha-1) than all other treatments and was studied the effect of different weed control treatments in turmeric. They found that application of atrazine resulted in marked reduction in dry matter accumulation of weeds after 30 days of sowing followed by metribuzin and straw mulching, The application of straw mulching recorded higher yield of fresh rhizomes (65 q ha-1). Atrazine {2-chloro-4-(ethylamino)-6 isopropylamino-1, 3-5-triazine} is a widely used 5- triazine herbicide. It is used as pre-emergence herbicide in the control of broadleaf and grass weeds in a variety of commercial crops as well as roadside and fallow fields (Munier lamy et al., 2002).Singh et al. (2003) pointed that atrazine at 0.50 kg ha-1 registered 79 per cent weed control efficiency followed by two hand weeding with 87 per cent WCE and one weeding followed by earthing up treatment with maximum (93%) WCE at 45 DAS indicating suppression of first flush of weeds successfully in maize. Kolage et al. (2004) reported that among the herbicides, pre-emergence spraying of atrazine at 1.0 kg ha-1 reduced the weed intensity substantially and recorded lower weed index and maximum weed control efficiency as compared to other herbicides used in maize. Rao et al. (2009) investigated that pre-emergence application of atrazine 1.5 kg ha-1followed by hand weeding at 30 DAS recorded lower weed dry weight at 60 DAS and harvest in maize.
