Evaluation of water productivity for maize under drip irrigation

Abstract: 
A drip system operating under deficit irrigation was used to evaluate water productivity (WP) of TMV-1 maize variety in Morogoro, Tanzania. A block was divided into four sub-blocks; and each randomly assigned with deficit treatment (T1, T2, T3 and T4 as 60%, 40%, 20% and 0% irrigation water deficits, respectively). Three replications were used producing randomized block design. Each sub block biomass, grain yield and harvest index were determined. Biomass development and grain yield were significantly (0.1<P<0.05) influenced by water deficit. Both increased with increasing irrigation water to full irrigation. WP were different (P=0.1), with T2 having the highest value (2.2 kg/m3).
Un système d’égouttement fonctionnant sous l’irrigation de déficit a été employé pour évaluer la productivité de l’eau (WP) de la variété de maïs TMV-1 à Morogoro, en Tanzanie. Un bloc a été divisé en quatre sous-blocks et chacun aléatoirement assigné avec le traitement de déficit (T1, T2, T3 et T4 en tant que déficits de l’eau d’irrigation de 60%, de 40%, de 20% et de 0%, respectivement). Trois répliques ont été employées en produisant la conception randomisée de bloc. Chaque biomasse d’un sous-bloc, le rendement de grain et l’ index de moisson ont été déterminés. Le développement de biomasse et le rendement de grain ont été sensiblement (0.1<P<0.05) influencés par le déficit de l’eau. Tous les deux ont augmenté avec l’augmentation de l’eau d’irrigation à la pleine irrigation. Les productivités de l’eau étaient différentes (P=0.1), avec le traitement T2 ayant la valeur la plus élevée (2.2 kg/m3).

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"
