Journal Article 2017

Autor: Howeler, Reinhardt H.

This chapter discusses various sources of nutrients to be applied to prevent soil nutrient depletion, as well as the optimum rates, times and methods of their application. It also describes how computer models can predict site-specific nutrient requirements and balanced fertilizer rates to maximi...

The effect of inoculating cassava with mycorrhizae on plant growth and P uptake was studied in sterilized and nonsterilized soils to which 8 levels of P were applied, as well as in a flowing culture solution at 4 different P concn. Inoculation produced greater than benefits in cassava grown in st...

The results are given of physicochemical analyses of soils and estimated cassava yields for five production zones in Colombia. There was little correlation between yield and the factors studied. Yields tended to increase as P increased; and there was a positive response to K in 2 zones and Ca/Mg ...

Cassava is among the food crops that tolerate soil acidity well; therefore, it is often planted on highly acid, unfertile soils without fertilization or liming. Nevertheless, cassava needs large quantities of P for maximum productivity. In fertilization trials at Carimagua (Llanos Orientales, Col...

Cassava is drought-tolerant and grows reasonably well in relatively infertile soils where other crops would fail. However, production could be further increased if important soil-related constraints are addressed. In order to supply cassava plants with the nutrients required for optimal productio...

In May 1980 the soil section of CIAT's cassava program established a fertilization trial with 3 cassava var. [Barranquena (regional), M Col 113, and CMC 921 to measure its effect on yield and establish optimum levels from an economical point of view. The trial took place in Mondomito and Agua Bla...

En mayo de 1980 en la seccion de suelos del programa de yuca del CIAT se establecio un ensayo de fertilizacion con 3 var. de yuca (Barranquena (regional), M Col 113 y CMC 92) para medir su efecto en el rendimiento y establecer los niveles optimos desde el punto de vista economico. El ensayo se lo...

Field inoculation trials with cassava (Manihot esculenta Crantz) were conducted in Quilichao (typic Dystropept soil) and Carimagua (Haplustox soil). In Quilichao, with a large and effective native VA-mycorrhizal (VAM) population, inoculation withGlomus manihotis did not increase cassava yields si...

Cassava (Manihot esculenta Crantz) was grown in the greenhouse and in the field at different levels of phosphorus applied, with or without inoculation with VA mycorrhiza in sterilized or unsterilized soil. When grown in a sterilized soil to which eight levels of P had been applied the non-inocula...
