Cassava (Manihot esculenta) yield in different spatial arrangements

Abstract

Experiments were carry out at the National Institute of Agricultural Sciences, San José de las Lajas, Havana, Cuba, during 1993 and 1994. Experiments were conducted on a compated Ferralitic Red soil, in a randomized block design with 5 replicates. Cassava clones CMC-40 and Señorita were planted at different spatial arrangements 0.90x0.70; 0.70x1.0; 0.90x0.90; 0.90x1.0; 1.40x0.50; 1.40x0.60; 1.40x0.80; 1.80x0.50; 1.80x0.65 m. Experiments were planted in monoculture. Cassava yield and its components were evaluated. Results showed a differential response between the 2 clones along the used arrangements. In clone CMC-40, the best yield, 40,93 t ha-1 in average, was obtained with the 1,40x0,60 and 0,70x1,0 arrangements. While in clone Señorita, the best yield (31,46 t  ha-1) was obtained with the 1,80x0,50 m arrangement.
