Journal Article 1990

Autor: Yaninek, John S. Gutiérrez, A.P. Herren, H.R.

Seasonally dense populations of Mononychellus tanajoa (Bondar), feeding on the leaves of cassava, Manihot esculenta Crantz, significantly reduced the leaf, stem, and storage-root dry matter of mite-infested plants. Stressed plants met metabolic demands by remobilizing the dry matter in stems and ...

A biotype of the annual grass weed hare barley infesting an alfalfa field with a 24-yr history of the use of the bipyridylium herbicides paraquat and diquat, was investigated for resistance to these herbicides. Rates of up to 800 g ai ha–1 of each herbicide caused no mortality in the hare barley ...

Drought stress was imposed on 2 cassava cv. (M Col 22 and M Mex 59) at Santander de Quilichao (Colombia), by withholding rainfall from field plots (plastic covers were placed over the soil surface) for 10 wk, commencing when crops were 12 wk old. The plants were then allowed to recuperate until t...

Cassava is an important food and cash crop in Malawi. It is also becoming increasingly important for industrial use. The aim of this study was to investigate the native starch quality of different Malawi cassava genotypes. Trials were conducted at Chitedze and Makoka in Malawi in the 2000/01 seas...

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...

Whole small tubers and setts from 15 genotypes of white yam (Dioscorea rotundata) at their post-dormant stage were planted at the beginning of the rainy season in 2003 and 2004. Harvesting was done at monthly intervals from three months after vine emergence (MAVE) till when there was senescence o...
