Groundnut agronomy in Cote-d'Ivoire
1993
Amalaman, A. | Placide, N.K.
Groundnut is the most widely grown legume in the Cote d'Ivoire, with a production of 80 000 to 100 000 tons per year. Higher fertilizer rates of 10-18-18 and single superphosphate did not improve groundnut pod yields. Varieties received from the Burkina Faso rust control program had good levels of resistance for rust in comparison with the controls. At Bouake, where rosette is endemic, all rust-resistant varieties were susceptible to rosette, with the exception of RH 152E. In contrast, at Ferkessedougou, these varieties performed well in terms of rust resistance. All local genotypes collected after 1989 and 1990 developed different levels of leafspots, rust and rosette symptoms with the exception of 10 which showed low disease symptoms. These 10 genotypes will be studied further to assess their agronomic characteristics in relation to infestation levels
