Stem‐nodulating Sesbania as a potential feed supplement for ruminants
Authors: Valarini Maria José , Possenti Rosana Aparecida 
Published: March 2006

AbstractSesbania rostrata can fix atmospheric nitrogen through both root and stem nodules. Its use as fodder was assessed on 4‐month‐old stem‐inoculated plants grown in the field. The shoots had high crude protein and degradable nitrogen, but low neutral‐detergent and acid‐detergent fibre, lignin, total extractable phenolics and tannins, and extractable condensed tannins. Dry matter and protein degradabilities were high. S. rostrata is a potential protein supplement for ruminants. Copyright © 2004 Whurr Publishers Ltd
Effect of harvesting method on quality and shelf‐life of mango fruits
Authors: Abu‐Goukh Abu‐Bakr A , Mohamed Hafiza I 
Published: March 2006

AbstractInstead of letting the fruits fall to the ground, mangoes were harvested by an improved technique. Fruits were snapped off the tree with a pole equipped with a long cloth sleeve held open by a ring. When the pedicel was severed, the fruit dropped into the bag and slid smoothly down to be received by the picker. The improved method greatly improved fruit quality, reduced post‐harvest losses and extended the shelf‐life. Copyright © 2004 Whurr Publishers Ltd
Seed weight and protein and tannin contents of 32 cowpea accessions in Ghana
Authors: Asante IK , Adu‐Dapaah H , Addison P 
Published: March 2006

AbstractCowpea seeds of 32 accessions had 100‐seed weight of 9.0 to 15.3 g and protein and tannin contents 16.4 to 27.3% and 0.12 to 2.38, respectively. Seeds that had the highest tannin levels were either brown mottled, dark mottled, brown or flesh‐coloured. There was a significant negative correlation between 100‐seed weight and protein content.

Growth and yield of Capsicum annuum var. Atarodo in response to weeding frequency and plant spacing
Authors: Nyambi GN , Koona P , Egunjobi JK , Awodoyin RO 
Published: March 2006

AbstractPlots of chilli pepper var. Atarodo weeded every 4 weeks had the same growth and yield as plots weeded every 6 weeks. Plant spacing of 100×50cm and 50×50cm had no significant effect on plant height, but the closer spacing increased the canopy width and the number of primary branches. The closer spacing gave 60% more yield. Copyright © 2004 Whurr Publishers Ltd

Lepidopterous stem borers of sorghum and their natural enemies in eastern Ethiopia
Authors: Tefera Tadele 
Published: March 2006

AbstractThree stem borers, Busseola fusca, Chilo partellus and Sesamia calamistis. attacked sorghum. B. fusca was widely distributed from 1290 to 2530 m above sea level and it was predominant in 95% of the sites. C. partellus and S. calamistis were found in lower altitude areas. Three larval parasitoids, Cotesia flavipes, Dolichogenidea fuscivora and Megaselia scalaris, were recorded but they made little contribution to controlling stem borers, with only 8% parasitism.

Development of serological procedures for rapid, sensitive and reliable detection of yam mosaic virus in yam tissues
Authors: Njukeng AP , Atiri GI , Hughes Jd'A , Winter S 
Published: March 2006

AbstractA monoclonal antibody, designated YMV‐M24, against yam mosaic virus (YMV), genus Potyvirus, was used to develop a triple antibody sandwich (TAS)‐ELISA, dot blot immunoassay (DBI), direct tissue blotting immunoassay (DTBI) and an immunosorbent electron microscopy (ISEM) for the detection of the virus in yam tissues. DBI was most sensitive. DTBI detected YMV in yam tubers and tuber sprouts. TAS‐ELISA, DBI and DTBI showed that the concentration of YMV increased from the base towards the tip of yam tuber sprouts. YMV‐M24 decorated YMV particles in ISEM. Copyright © 2004 Whurr Publishers Ltd

Storage practices and aflatoxin B1 contamination of ‘egusi’ melon seeds in Nigeria
Authors: Bankole SA , Lawal OA , Adebanjo A 
Published: March 2006

AbstractIn the rain forest and northern guinea savanna of Nigeria, melon seeds in farmers' stores are usually kept in woven polypropylene bags, or less often in jute sacks. Seed mouldiness was the main storage problem and when farmers noticed it, they brought the seeds out for redrying and sorting. Aflatoxin B1 contamination was detected at levels above 5µg/kg in 35.6% of the forest and 27.4% of savanna samples with mean levels of 13.7 and 12.1µg/kg respectively. The incidence of diseased seeds positively correlated with levels of aflatoxin B1. The samples stored for up to two months did not contain detectable levels of aflatoxin, but thereafter the incidence and level of aflatoxin increased. Copyright © 2004 Whurr Publishers Ltd
Nutrient deficiency symptoms in yams (Dioscorea spp.)
Authors: Shiwachi H , Okonkwo CC , Asiedu R 
Published: March 2006

AbstractSymptoms of nutritional deficiencies in D. alata and D. rotundata were observed when yam plants were grown in nutrient solutions from which any of the following had been omitted: N, P, K, Ca, Mg, Zn, Fe, B, Mn, Cu and Mo. The symptoms of deficiency of major elements were visible on plants of both species. The omission of Fe, B and Mo produced characteristic symptoms on the leaves of D. rotundata, but D. alata showed symptoms only in response to Fe deficiency. The omission of minor elements led to poor growth of the leaves, stems and roots. Nutrient deficiencies in yam plants could be diagnosed by visual symptoms in the field.

Microbiology of the production of Oso, a condiment made by fermenting seeds of Cathormion altissimum
Authors: Popoola TOS , Jolaoso AA , Afolabi RO 
Published: March 2006

AbstractOso is a condiment used in soups in Nigeria, produced by the fermentation of Cathormion altissimum seeds. Bacillus substilis, B. linchenformes, Leuconostoc mesenteroides and a species of Staphylococcus were isolated from the fermentation medium. No significant difference was observed in the quality of Oso obtained by the traditional method and that produced under aseptic laboratory conditions. All the bacteria isolated were able to ferment the seeds individually, but the product was of poor quality. Copyright © 2004 Whurr Publishers Ltd
Effect of processing conditions on the extrusion of white yam flour (D. rotundata)
Authors: Sebio L , Chang YK 
Published: March 2006

AbstractWhite yam flour had high paste stability during heating. Low moisture contents, independently of barrel temperature, gave higher values of the expansion index. The bulk density was influenced directly by feed moisture content and the barrel temperature. Only barrel temperature had a major effect on the colour change. Prediction equations for these properties could be used to select processing conditions for specific applications. Copyright © 2004 Whurr Publishers Ltd
Comparative effects of explant sources and genotypes on microtuberization in yams (Dioscorea spp.)
Authors: Balogun MO , Ng SYC , Shiwachi H , Ng NQ , Fawole I 
Published: March 2006

AbstractSingle node cuttings of two genotypes each of Dioscorea alata and D. rotundata from both plants grown in screen houses and in vitro plantlets were cultured in a tuberization medium. The screen house explants had significantly higher plantlet tuberization and primary nodal complex formation, and more tubers and primary nodal complexes per plantlet than in vitro explants, whereas in vitro explants performed better only in nodes per plantlet. It appears that in vitro tuberization is explant‐, species‐ and genotype‐dependent, the greatest variation being due to explant source. This is a first report of microtuber production from nodal explants of D. rotundata produced in a screen house. Copyright © 2004 Whurr Publishers Ltd
In‐situ chlorophyll fluorescence and related growth of white Guinea yam at different ages
Authors: Aighewi BA , Ekanayake IJ 
Published: March 2006

AbstractLeaf chlorophyll photochemical attributes and growth of two cultivars of white Guinea yam (Dioscorea rotundata) were examined. The photochemical efficiency (Fv/Fm ratio) of cv. Pepa was significantly higher than that of cv. Abi at 10, 14 and 22 weeks after transplanting (WAT). The peak photosynthetic efficiency period for both cultivars was at 18 WAT. Leaf area indices and crop growth rate were greater for Pepa than Abi, as was the leaf transpiration rate. During peak growth periods Pepa was less stressed than Abi according to midday leaf water potentials and stomatal conductance. Copyright © 2004 Whurr Publishers Ltd

Allelopathic effects of Parthenium hysterophorus extracts on seed germination and seedling growth of lettuce
Authors: Wakjira Mulatu , Berecha Gezahegn , Bulti Befekadu 
Published: March 2006

AbstractAqueous extracts of Parthenium hysterophorus leaf and flower seriously inhibited seed germination and seedling growth (root and shoot length) of lettuce. Extracts of the root and stem had much less effect. Lettuce roots were more sensitive to the allelopathic effect than shoots. It appears that early removal of Parthenium weed from lettuce fields is essential to avoid poor germination and seedling growth. Copyright © 2005 John Wiley & Sons, Ltd
Mini tuber production using yam (Dioscorea rotundata) vines
Authors: Shiwachi H , Kikuno H , Asiedu R 
Published: March 2006

AbstractMini tubers were produced from two varieties of Dioscorea rotundata using vine cuttings planted in carbonized rice husk or coco‐peat in a screen house. The cuttings established better and produced more mini tubers in carbonized rice husk than in coco‐peat 100 days after planting. Vine cuttings of seven varieties planted in carbonized rice husk produced 1.7 ± 0.8 mini tubers per cutting with mean weight of 3.0 ± 2.7 g and 70.1% moisture content. About 63% of these sprouted after 77–105 days of storage under ambient air temperature. Vine cuttings of D. rotundata can be used to produce mini tubers within 100–120 days that could be used in germplasm exchange and for production of seed yams. Copyright © 2005 John Wiley & Sons, Ltd
Onions in West Africa: state of research and future prospects
Authors: Rouamba Albert , Currah Lesley 
Published: March 2006

AbstractThe evaluation of local ecotypes has promoted their exploitation in breeding schemes and the creation of lines resistant to thrips and to pink root rot. Promotion of the cultivar Violet de Galmi from Niger has helped to improve onion yields throughout the region. Three distinct groups of ecotypes of onions can be characterized by their yield, their earliness and their storage performance. Improved local varieties have been brought into commercial use. Several onion lines are being used for breeding varieties resistant to bolting and with good storage capability. Copyright © 2005 John Wiley & Sons, Ltd
Effect of photoperiod on the development of inflorescences in white Guinea yam (Dioscorea rotundata)
Authors: Shiwachi H , Ayankanmi T , Asiedu R 
Published: March 2006

AbstractIn experiments in 2001 to 2003, 50‐day‐old plants of four varieties of white Guinea yam (D. rotundata) were exposed to 10 h (short‐day) day length for 15 days, 14 h for 30 days or constant 24 h, with natural day length as the control. Under natural day length the male varieties flowered earlier than the female. Short day‐length delayed and reduced the intensity of development of inflorescences, but the response to the 14 h and 24 h treatments differed between the varieties.

The supplementation of haricot bean residue with lablab (Lablab purpureus) hay in the diet of Arsi bulls and heifers (Bos indicus)
Authors: Ebro Abule , Tadesse Temsegen , Abebe Tekele 
Published: March 2006

AbstractArsi bulls and heifers were fed for 111 days with haricot bean residue alone or supplemented with 0.5, 1.0 or 1.5 % of their body weight with lablab hay. Supplementation, especially with 1.0 and 1.5% increased the dry matter intake and weight gain (P<0.001). The supplements were economically profitable: unsupplemented, there was a loss of 0.275 Ethiopian Birr (ETB)/day, but with 0.5, 1.0 and 1.5% lablab supplementation there was a profit of 0.051, 0.320, 0.425 ETB/day respectively (US$1=8.67 Birr).

Relationship between pheromone trap catches of Coniesta ignefusalis and larval infestation of a millet crop in Ghana
Authors: Tanzubil Paul B , Mensah GWK , McCaffery Alan R 
Published: March 2006

AbstractAdult male flight activity of the stem borer, Coniesta ignefusalis, was monitored from May 1996 to December 1997 using pheromone traps at the Manga Research Station in the Sudan savanna zone of Ghana. There appeared to be four generations per year, with peaks in June, July, September and October. For both years, the first peaks obtained from diapause larvae were the smallest. There was a significant positive correlation between trap catches and larval numbers in millet 3 weeks later and also between trap catches and the number of bored plants 3 weeks later. There was no significant relationship between larval infestation and crop damage, suggesting that larval count alone may not be a reliable indicator of C. ignefusalis damage to millet.

Phenyl acetic acid‐induced in vitro shoot multiplication of Vanilla planifolia
Authors: Giridhar P , Vijaya Ramu D , Ravishankar GA 
Published: March 2006

AbstractVanilla planifolia can be propagated using phenyl acetic acid (PAA) as a primary factor to induce multiple shoots from axillary buds. Shoots can be induced and then elongated in media containing MS salts, vitamins, 6‐benzyladenine (BA) and PAA. Elongation of shoots and formation of new shoots from nodes was achieved on medium containing BA+PAA. The shoots could be rooted on a medium supplemented with indole butyric acid and after hardening and transfer to the field, 70–80% survived. Copyright © 2003 Whurr Publishers Ltd
Early selection for resistance to Phytophthora megakarya in local and introduced cocoa varieties in Cameroon
Authors: Nyassé S , Efombagn Mousseni IB , Bouambi E , Ndoumbe‐Nkeng M , Eskes AB 
Published: March 2006

AbstractResistance to Phytophthora megakarya in cocoa tree genotypes was assessed at an early stage by inoculation of leaf discs taken from nursery plants. Four hybrid progenies introduced from Côte d'Ivoire and known to be resistant to P. palmivora in that country were compared to local control clones known for their lower susceptibility to P. megakarya, and to progenies produced in Cameroon. There was highly significant variability for resistance between progenies, and between individual plants within the progenies. The progenies from Côte d'Ivoire were more resistant to P. megakarya than the control clones from Cameroon, and also when compared with the progenies produced in Cameroon. This shows the potential of the progenies from Côte d'Ivoire for controlling black pod in Cameroon and reliability of the leaf disc inoculation method. Copyright © 2003 Whurr Publishers Ltd
