About the RUFORUM 2010 Biennal Conference
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholders in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme of Natural Resource Management"
Determining appropriate mode and rate of applying lime to improve maize production in acid soils of north Kakamega and Siaya districts, Kenya
Abstract:
Increasing soil acidity is a major cause of low soil fertility in
western Kenya where about 57,670 hectares is acidic. While
liming can increase soil pH, the most appropriate method of
application needs to be determined. This study aimed at
determining the best method of applying lime by comparing
three methods, Broadcasting, Banding and Spot, using four lime
rates (0, 2, 4 and 6 t ha-1) in North Kakamega and Siaya districts
and using maize as a test crop. One time application of lime
using the three methods was done during planting with 26 kg
ha-1 phosphorus and 75 kg ha-1 nitrogen applied as blanket. Data
were collected on percentage seed emergence, crop height,
tissue chemical composition and grain yield. The results
indicated low germination percentage with 6 t ha-1 of lime applied
via spot (85.2-94.8%) as compared to control (91.8-98.1%).
The heights taken 67 days after sowing were 43% higher than
control for 6 t ha-1 banded lime plots in North Kakamega district
and 38.07% higher than control for 4 t ha-1 broadcast lime in
Siaya district.
L’acidité croissante du sol est une cause importante de la basse
fertilité du sol au Kenya occidental où environ 57.670 hectares
de terre sont acides. Tandis que le chaulage peut augmenter le
pH du sol, la méthode d’application la plus appropriée doit être
déterminée. Cette étude a visé à déterminer la meilleure façon
d’appliquer la chaux en comparant trois méthodes : la semis à
la volée, sur des planches de semis et des spots, en utilisant
quatre taux de chaux (0, 2, 4 et 6 t ha-1) dans les districts du
nord de Kakamega et de Siaya et en utilisant le maïs comme la
culture d’essai. Une seule application de chaux employant les
trois méthodes a été faite pendant la plantation avec 26 kg
ha-1 de phosphore et 75 kg ha-1 d’azote appliqués comme
couverture. Des données ont été rassemblées sur le pourcentage
d’apparition de graine, la taille de culture, la composition chimique
du tissu et le rendement en grain. Les résultats ont indiqué le faible pourcentage de germination avec 6 t ha-1 de chaux
appliqués a travers des spots (85.2 à 94.8%) par rapport à la
référence (91.8 à 98.1%). Les tailles prises 67 jours après
l’ensemencement étaient 43% plus hautes que la référence pour
6 t ha-1 de parcelles de chaux réunies dans le district du nord de
Kakamega et 38.07% plus hautes que la référence pour 4 t
ha-1 de chaux d’émission dans le district de Siaya.
