Effect of Different Drip Irrigation Regimes on Growth, yield and Yield Components of Banana cv. Grand Nain Under Gizera Condition, Sudan

This study was conducted to investigate the effect of different water regimes applied by drip irrigation on growth and yield of banana cv. Grand Nain in Gizera State. Five different irrigation regimes were applied. These were 40%, 60%, 80%, 100% and 120% of crop evapotranspiration (ETc) at a 2-day irrigation interval. The experimental design was a randomised complete block (RCBD) with 4 plants per plot. Banana growth parameters increased with the increase in quantity of water applied up to 100% of ETc. Bunch weight, total yield, number of hands per bunch and numbers of fingers per bunch were linearly related to the amount of water applied in the plant crop and first ratoon. There were no significant differences in bunch weight between 100% and 120% of ETc of mother plant and first ratoon.
Cette étude a été menée pour étudier l’effet des différents régimes d’eau, appliqués à l’irrigation par gouttes sur la croissance et le rendement de la banane cv. Grand Nain dans l’Etat de Gizera. Cinq différents régimes d’irrigation ont été appliqués. Il s’agissait de 40%, 60%, 80%, 100% et 120% de l’évapotranspiration des cultures (ETC) à un intervalle d’irrigation de 2 jours. Le dispositif expérimental était un bloc aléatoire complet (RCBD) avec 4 plantes par parcelle. Les paramètres de croissance des bananes ont augmenté avec l’augmentation de la quantité d’eau appliquée jusqu’à 100% d’ETC. Le poids des régimes, le rendement total, le nombre de mains par régime et les nombres de doigts par régime ont étéen relation linéaire avec la quantité d’eau appliquée dans la culture des plantes et le premier rejet. Il n’y avait pas de différences significatives dans le poids du régime entre 100% et 120% d’ETC de la plante mère et du premier rejet.

The 2012 RUFORUM Biennial Conference is the third 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 stakeholers 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. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under Integrated Crop Management
