Growth and N uptake in pot-grown maize, beans, and cassava were evaluated under 2 levels of soil N at CIAT-Palmira (Colombia). The lower amount of the element reduced its uptake by the 3 species, resulting in lower tissue concn., especially in the leaves. Under low N, DM accumulation was also red...

Crescimento, fotossintese e eficiencia do uso de nitrogenio em milho, feijao e mandioca submetidos a dois niveis de N no solo
Results are presented of various trials with cassava. The importance of DM production and factors affecting it, such as LAI and leaf inclination, are discussed. The relative importance of DM production and its distribution, particularly in relation to spacing, are reviewed. The author suggests a ...
Se presentan los resultados de varios ensayos con yuca. Se discute la importancia de la produccion de MS y los factores que la afectan, tales como el IAF y la inclinacion de la hoja. Se revisa la importancia relativa de la produccion de MS y su distribucion, particularmente en relacion con la den...
Forty different cultivars of cassava were grown in unreplicated plots at a plant population of 20,000 plants/ha in fertile soil. Harvests were taken at 4, 6, 8, 10 and 12 mo after planting 18 varieties. The characteristics of the 2 highest yielding varieties, M Colombia 113 (66 tons/ha) and M Col...
Three varieties in one cassava trial and 5 in another were planted in a sytematic density experiment, which showed that optimum plant density for root yield changes with plant age. Some varieties showed a pronounced optimum plant population whereas others showed a flat-topped response curve. Redu...
