Effect of density on the yield of cassava (Manihot esculentum Crantz) cv. Valencia.
Keywords:Manihot esculentum, density, number and diameter of tuberous roots, yield, Nicaragua.
A study of cassava
(Manihot esculenta Crantz) cv. Valencia was carried out in
June of 2001, in San José de Monte Redondo, Municipality
of Masatepe, Masaya Department, Nicaragua. The objective
of this test was to assess the effect of 14 286, 15 385, 16 667,
18 182, 20 000 y 22 222 plants per hectare on the components
of yield. Spacing was 1m between rows and 0.70, 0.65, 0.60,
0.55, 0.50 y 0.45 m between plants respectively. The
experimental design used was a completely randomized
blocks design, with four replications. Higher emergency of
plants (91.75 %) was obtained with a population of 16,667
plants per hectare (1 x 0.6 m). The highest number of
tuberous roots was 5.13 in a density of 14 286 plants per
hectare (1 x 0.7). The largest diameter of root (5.20 cm), and
the best yield (27.75 t/ha) were obtained with a plant
population of 15 385 plants per hectare, when plants were
sown at 1 m between rows and 0.65 m between plants. This
density caused the formation of the highest quantity of roots
