Flower initiation in some plant species is associated with the physical and chemical soil characteristics such as the availability of certain mineral elements and soil moisture status. The objective of this study was to examine the effects of soil physicochemical traits on the differential flower...

The integration of multipurpose legumes into low-input tropical agricultural systems is needed because they are a nitrogen (N) input through symbiotic fixation. The drought-tolerant cover legume canavalia (Canavalia brasiliensis) has been introduced for use either as forage or as a green manure i...

In Cambodia, cassava is mostly grown with little or no fertilizer inputs, but the
magnitudes of nutrient balances are not known. This study was conducted to assess
nutrient balances for cassava cultivation in Kampong Cham province in Northeast
Cambodia. Forty five households in four cassava pr...

The application of nitrogen in a soil under agricultural production is subject to several pathways including de-nitrification, leaching and recovery by an annual crop. This is as well greatly influenced by the management practices, nitrogen source and soil conditions. The main objective of this s...

Potential N (SN) and P (SP) supplies, N and P utilization efficiencies and fertilizer recovery rates for the northern Guinea Savanna (NGS) agro-ecological zone of Nigeria were derived from data collected on farmers fields, and used as input in the QUantitative Evaluation of the Fertility of Trop...
This work determined the inter-relationships between constituents, rumen dry matter (DM) and nitrogen (N) degradabilities of fresh leaves from 20 multipurpose tree (MPTs) accessions belonging to the following genera: Acacia(2), Cajanus (2), Chamaecytisus (2), Erythrina (2), Leucaena (8) and Sesba...
