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...

Variability in 42 orange-fleshed sweet potato hybrids for tuber yield and carotene and dry matter content.
The effect of alley cropping with seven combinations of Acioa and Leucaena hedgerows and a control (no hedgerow) treatment on sequentially cropped maize and cowpea was studied in 1985 and 1986. The trial was carried out on an Alfisol in the humid zone of southwestern Nigeria. Hedgerows were estab...
An experiment was conducted to study the performance of nine genotypes of potato under hill zone of Karnataka. Among nine genotypes, maximum tuber sprout percentage was observed in Kufri Jyoti (100) followed by TT7011 (98.75) and least percentage was in C-28 (89.16). Kufri Jyoti performed better ...

Sweetpotato (Ipomoea batatas L. (Lam)) is a nutritious food security crop for most tropical households, but its utilisation is very low in Ghana compared to the other root and tuber crops due to lack of end-user-preferred cultivars. Knowledge on the genetic control of important traits such as dry...

Cassava is predominantly an upland crop that is also cultivated in inland valley swamps (IVS). Identifying physiological traits that can withstand excess moisture stress can aid in the selection and use of stable cassava cultivars in IVS. Three cassava cultivars were evaluated for growth and yiel...

This paper applies econometric analyses to quantitatively determine the individual risk attitudes of sampled maize farmers in the dry savanna zone of Nigeria. The extent of the risk attitudes are then made the basis for categorizing the farmers into three groups of low, intermediate and high risk...
