Titre de série : The Empire Journal of Experimental Agriculture, n°105 Titre : The effect of spacing on the environment and performance of Cacao under Nigerian conditions I. agronomy Type de document : texte imprimé Auteurs : Kowal, J. M. L. Année de publication : 1959 ISBN/ISSN/EAN : CI-04287 Note générale : The present paper records results obtained from a Cacao spacing trial during 1942-1956 and the effect of density of planting on the establishment and performance of mature cacao. It is an account supplementary to that given by Russell which covers the initial period 1942-1952/ and is intended to form a basis for a subsequent paper dealing with the effect of tree density on soil intrate, soil-moisture fluctuations, and micro-climatic conditions under cacao.

Titre de série : The tempire journal of experimental Agriculture Titre : The effect of spacing on the environnement and performance of cacao Nigerian conditions: II. Ecological factors (soil moisture, soil nitrates, shode and micro - climatic conditions) Type de document : texte imprimé Auteurs : Kowal, J. M. L. Année de publication : Avril ISBN/ISSN/EAN : CI-08543 Note générale : A comparative study of cacao at different stand densities, and secondary forest, has been made with special reference to soil moisture, soil nitrates, shade and micro - climatic conditions. The level of soil organic metter and plant nutrients was higher and the physical condition of the soil better, under the forest than under cacao. A high positive correlation was found between stand density and soil noisture, soil nitrates, organic litter, soil nutrient status, and the yield of cacao .
