IN VITRO MORPHOGENIC PERFORMANCE OF GINGER (ZINGIBER OFFICINALE) AS INFLUENCED BY MEDIA VARIATIONS

ABSTRACT Ginger (Zingiber officinale Rose) is a perennial herb that grows from underground rhizomes. The demand for fresh and dry ginger and its essential oil in the world market is high. Ginger is propagated vegetatively using underground rhizomes. Most farmers use planting materials saved from previous harvest. These materials could have been sold for cash. Contingent

SIMPLE SEQUENCE REPEAT (SSR) GENETIC ANALYSIS OF CASSAVA MOSAIC DISEASE RESISTANCE IN SELECTED F1 POPULATIONS OF CASSAVA

ABSTRACT Cassava mosaic disease caused by begomoviruses is the most widespread disease of cassava in Africa. Simple sequence repeat (SSR) genetic analysis of an F1 population of cassava was carried out to identify new sources of CMD resistance. Genomic DNA extracted from parents and progeny was amplified using polymerase chain reaction (PCR). PCR amplifications were

EVALUATION OF CASSAVA CULTIVARS AND INTERCROPPING WITH LEGUMES AS AN INTEGRATED NEMATODE PEST CONTROL STRATEGY IN CASSAVA (MANIHOT ESCULENTA CRANTZ) PRODUCTION

ABSTRACT These studies on evaluation of cassava cultivars and intercropping with legumes as an integrated nematode control strategy in cassava      production were carried out as greenhouse/microplot and field experiments. Of the 200 cultivars screened for resistance to Meloidogyne spp., only 76 survived and from this lot only 3 lines 77/227, TMS30572 and 73/222, showed any resistance

PHOSPHATE MOBILIZATION BY ADDITION OF ORGANIC ACIDS IN TWO SOILS OF THE SOUTHERN GUINEA SAVANNA OF NIGERIA

ABSTRACT One mechanism by which plants can mobilize organic and inorganic forms of phosphorus (P) in soils is by exudation of low molecular weight organic acids. Laboratory and field trial were carried out during 2011 and 2012 cropping seasons to study the effects of additions of organic acids ( citric, oxalic and tartaric acids) on
