Comparative study of storage methods of maize grains in South Western Nigeria

Laboratory experiment was conducted to assess the efficacy of different storage methods of maize grains in Ibadan (a humid tropical ecology) between year 2002 and 2003. The results shows that storage methods (SM), treatment (Tr), SM x Variety (V) and Tr x V interactions were highly significant for numbers of undamaged maize grains (

Variation in maize tolerance to Striga Lutea (Lour) and influence of Arbuscular Mycorrhizal Fungi

This study was conducted to assess the variation in maize tolerance to Striga lutea and influence of arbuscular mycorrhizal fungi (AMF). Screen house experiment was conducted at the Institute of Agricultural Research and Training, Ibadan while, Farm settlement and Temidire were striga endemic experimental fields in Eruwa. Complete randomized design was used in screen house while, randomized complete block design was adopted on the field with three replications. AMF (Glomus mosseae, G. clarum, G. deserticola and Gigaspora gigantea) in mixtures of soil and root fragments were inoculated at the rate of 25g per plant while, 10.4g of extracted striga seeds were artificially  infested. Uninoculated and uninfested in pots and plots served as control. Four maize genotypes; ILE1- OB, ART-98-SW4-OB, ART-98-SW5-OB and ART-98-SW6-OB were screened for tolerance or susceptibility to S. lutea infestation on disease rating scale of 1 to 9. ART-98-SW5-OB and ART-98-SW6-OB were significantly tolerant (P<0.05) with striga damage rating (SDR) ranging from 1.18-2.48, ART-98-SW4-OB was moderately tolerant with SDR ranging from 3.59-4.57, while ILE-OB was highly susceptible with SDR ranging from 8.61-8.72. Influence of AMF was significant (P<0.05) for growth, yield and striga-related traits with SDR ranging from 1.28- 2.70 and 1.21-2.64 at 8 and 10 weeks after planting respectively.Key words: Maize, mycorrhiza, Striga lutea, tolerance, yiel

Reaction of some maize genotyhpes to infestation with the witch weed (Striga asiatica)

A total of twenty four maize genotypes comprising nine inbreds, six open pollinated, four synthetic and five hybrids were tested for tolerance to artificial infestation of Striga asiatica using seeds of the pest as inoculum source. Yields varied directly with tolerance level and reduction in plant height was observed with increase in age of the maize plants between 8 and 10 weeks after planting in most of the genotypes. Although, stem girth was not significantly different under striga infestation, plant height and leaf-area at 8 - 10 weeks were significantly different in the infested maize plants. Striga emergence counts was significant with marked effect on yield, while Striga damage rating ranged between two and four in tolerant genotypes and between five to nine among susceptible ones. Two inbreds (EV8485-Y and EV8725-100-2) STR, one hybrid (9044-27-Y) and one synthetic (NEW STR-1-W) were found to be tolerant to Striga asiatica. The tolerant maize genotypes may be desirable for introduction to S. asiatica endemic regions of Southern Guinea Savanna.

Trade Policy Reforms and Sectoral Employment in Nigeria

Trade policy change concomitant with aggressive outward orientation was a major bedrock of Structural Adjustment Programme (SAP) adopted by Nigeria in 1986. Trade reform has clear implications for the overall economic performance, in terms of either employment creation or destruction as well as labour reallocation. Against this backdrop, this study examined the empirical relationship between trade liberalisation and sectoral employment in Nigeria using time-series macroeconomic data from 1986 to 2008. Three key sectors of the economy covered by the study are manufacturing, agriculture and services.The study employed Ordinary Least Squares to measure the impacts of trade liberalisation on sectoral employment. The result revealed that the trade liberalisation impact on employment differed across sectors; and that trade reforms have no significant effect on sectoral employment during the period covered. The study recommended that trade liberalisation should be embedded in a coherent set of macroeconomic, structural and social policies in order to be successful in terms of employment generation. Also, active labour market policies should be put in place and underscored to facilitate adjustment to changes in production structure brought about by trade and trade reforms.Keywords: Trade liberalisation, Sectoral employment, Ordinary least squares, Serial correlation.JEL Classification: F16, J21, J23
