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...

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 ...

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...
