Impact of Production Inputs and Timing on Crackness of Rice in Northern Ghana

Under rain-fed conditions, perfumed rice production in Northern Ghana is associated with high paddy cracking during milling. In this study, 4 perfumed rice varieties, 6 staggered planting times, 6 staggered harvesting cycles, and staggered storage duration from harvest to six months of storage were used in a randomized complete block design to identify the best combination of factors that are associated with low cracking in rice production. )e experiment was laid out in a randomized complete ...

Assessment of selection techniques in genotype X environment interaction in cowpea Vigna unguiculata (L.) walp

Ten genotypes of cowpea were grown in four environments comprising the early and late seasons of Ogbomoso and Abeokuta locations in 2005 and 2006. Joint linear regression analysis indicated the presence of Genotype x Environment interaction even though, a proportion was non-linear. The differences in the values of the regression coefficient and the correlation of grain yield revealed that the genotypes responded differently to the environments and that regression coefficient as a technique co...

Classification of genetic diversity and choice of parents for hybridization in cowpea Vigna unguiculata (L.) Walp for humid savanna ecology

Thirty-one accessions of cowpea of diverse eco-geographic origins were evaluated for genetic diversity using principal component analysis (PCA), single linkage cluster analysis (SLCA) and canonical techniques. The accessions were classified into six groups by PCA and SLCA while canonical technique identified five vector groups. There was no relationship between the clustering pattern and eco-geographic distribution. PCA and canonical techniques can be jointly used in multivariate analysis as ...

EFFECTS OF LEVEL OF POULTRY MANURE ON YIELD AND POST – HARVET QUALITY OF CELOSIA ORGENTIA

BSTRACT A field experiment was conducted at the Department of Agronomy, University of Ibadan to asses the effect of four levels of poultry manure on yield and post – harvest quality of celosia argentina. The levels of poultry manure used were 0, 10, 30 and 50t/ha. The growth and yield parameters measured were plant height, number of leaves, number of branches, fresh weight and total yield. The post harvest parameters were measured under three storage conditions i.e Ambient (25 – 270c) Eva...

PRESENT AGRO-BASED RESEARCH INSTITUTES IN NIGERIA, THEIR HISTORY AND OBJECTIVES

AFRICA REGIONAL FOR INFORMATION SCIENCE, UNIVERSITY OF IBADAN The idea of a school of information science for English speaking African countries was conceived at UNESCO in 1973, revived at Canada’s International Development Research Centre (IDRC) in 1980, and usefully bold to the meeting of commonwealth Head of Universities, held in Hong Kong, in March 1981.  In January 1983, a four man team of Experts visited many African universities in order to recommend to UNESCO and IDRC the best loca...
