    Effect of spacing and cutting management on survival, growth and biomass production of moringa oleifera intercropped with maize on-farm at Gairo Inland plateau, Morogoro in Tanzania
    (2012) Edward, Ezekiel; Chamshama, Shabani A.O; Ngaga, Yonika M; Mndolwa, Mathew A
    A study was carried out at Gairo, Tanzania to determine appropriate planting spacing and cutting management for optimising maize yield without jeorpadising the potential of Moringa oleifera to produce sufficient biomass. Two trials (on-farm spacing-intercropping and on-farm pollarding height-intercropping) were laid out using Randomized Complete Block Design (RCBD). Assessments were done at tree ages of 6, 12, and18 for the spacing trial and at tree ages of 6, 12, 18, 24 and 3 months for the pollarding trial. Grain weights were measured on a yearly basis (seasons). Plot means for all response variables were subjected to standard Analysis Of Variance (ANOVA) and significant means were separated by Duncan’s Multiple Range Test (DMRT). Results for the spacing trial showed that, overall all growth parameters increased significantly with spacing, and tree growth was generally higher in monoculture compared to intercropped plots. During the last assessment, foliar and stem biomass ranged from 571.57 kg/ha for maize+150cmpollarding height to 682.15 kg/ha for maize+50 cm pollarding height and from 181.72kg/ha for 150 cm pollarding height to 254.29 kg/ha for maize+100 cm pollardingheight respectively. Moringa intercropping is recommended to be done only duringthe first cropping season, due to severe competition thereafter.

    Survival, growth and biomass production of Moringa oleifera provenances at Gairo inland plateau and Ruvu coastal region in Tanzania
    (Academic Journals, 2014-01) Chamshama, Shabani A. O; Edward, Ezekiel; Ngaga, Yonika M; Mndolwa, Mathew A
    Survival, growth and biomass production was studied among 14 Moringa oleifera provenances at Gairo inland plateau-Morogoro, and Ruvu Coastal Region in Tanzania employing randomized complete block design with three replications. Growth assessment was done at six months intervals while biomass assessment was only done at 30 months. During final assessment, untransformed survival at Gairo site ranged from 65.33% for Chikwawa/Domasi (Malawi) to 98.67% for Ihumwa (Tanzania) while at Ruvu site, it ranged from 92% for PKM 2 (India) to 100% for Chikwawa/Domasi (Malawi), Mahalapye (Botswana) and Mbololo 472-029/03 (Kenya) provenances. Height ranged from 2.66 m for Makhanga (Malawi) to 5.04 m for Maun (Botswana) at Gairo site and from 4.82 m for Makhanga (Malawi) to 8.16 m for Maun (Botswana) at Ruvu site. Breast height diameter ranged from 2.80 cm for Makhanga (Malawi) to 6.07 cm for Mahalapye (Botswana) at Gairo site and from 5.18 cm for PKM 3 (India) to 8.58 cm for Maun (Botswana) at Ruvu site. Provenances Mahalapye and Maun (Botswana), Ihumwa (Tanzania), Mbololo 472-029/03 (Kenya) and PKM 1 (India) at Gairo site and Maun and Mahalapye (Botswana), Mbololo 472-029/03 (Kenya) and Ihumwa (Tanzania) at Ruvu site are recommended for planting at these and similar sites.
