Adoption and production of Moringa oleifera Lam. as an agroforestry and vegetable crop in Zimbabwean smallholder farming sector is considerably low. pH, phosphorus and nitrogen have been identified as major limiting factors for Moringa initial establishment and growth. A study was carried out to investigate the effects of pH, N and P on initial establishment and growth of M. oleifera. The objectives of this study were to determine optimum application rates of agricultural lime, N and P, and interaction of lime and fertilizers on Moringa growth. Sandy soil from Marange was used in the greenhouse experiment at Africa University. Three lime levels (0, 4000 and 8000 kg ha -1) and four N levels (0, 200, 400 and 800 kg ha -1 ammonium nitrate) were combined factorially with four levels of P (0, 100, 200 and 400 kg ha -1 P 2 O 5), in a randomized complete block design. Moringa plant height, shoot dry matter and root dry matter significantly increased with an increase in the amount of lime, ...
A greenhouse experiment was conducted to investigate the effects of NPK, poultry manure, and organomineral fertilizer on the growth and nutrient concentration of Moringa oleifera leaves. The experimental design was completely randomized design (CRD) with four treatments replicated three times. Data collected were analysed using descriptive statistics and ANOVA at í µí± = 0.05. Growth parameters measured include number of leaves per plant, plant height (cm), and stem girth (mm). The application of poultry manure increased the height, number of leaves, and stem girth of moringa compared to the application of NPK and organomineral fertilizer while the control had the least growth. Poultry manure, NPK, and organomineral fertilizer were 66%, 62%, and 39% higher in number of leaves than the control at eight weeks after planting. The application of poultry manure significantly (í µí± ≤ 0.05) increased the nutrient content of moringa leaves compared to other sources of fertilizer applied. The results shows that the application of poultry manure significantly (í µí± ≤ 0.05) improved the growth and nutrient content of moringa; however, further field trial is suggested.
Purpose The need for increasing production of Moringa oleifera in Nigeria can be achieved through adequate fertilization. This study investigated the effects of sources and rates of NPK (15:15:15) and compost on soil properties and productivity of Moringa at National Horticultural Research Institute, Ibadan, Nigeria. Methods NPK was applied at 30, 60, and 90 kg N/ ha, cow dung (CD), poultry manure (PM) and organomineral (OM) were applied at 10, 20 and 30 tons/ha. The experimental design was a randomized complete block design with three replicates. Organic fertilizers were incorporated into the soil 2 weeks before sowing; NPK was split applied at 2 and 5 weeks after sowing. Seeds were sown at 75 cm 9 75 cm spacing. Data were taken on plant height (cm), stem girth (cm), number of leaves, leaf biomass, stems weight and post-planting soil properties. Results Growth values for NPK and compost treatments were higher than the control. PM applied at 30 tons ha-1 resulted in highest growth values: plant height (65.91 cm), stem girth (1.51 cm) and number of leaves (14.20). PM applied at 30 tons ha-1 gave higher stem weight (2249.9 g) and leaf biomass (3610.5 g). Post-planting soil analysis indicated that nitrogen, phosphorus, calcium, sodium, manganese, iron and zinc contents were higher in plots with organic and inorganic fertilizers except for potassium and magnesium. Conclusion PM proved more superior to CD manure and others because it produced better growth attributes such as shoot height, stem girth and number of leaves and leaf biomass than its counterparts produced.
Growth performance and nutrient quality of three Moringa oleifera accessions grown as potherbs under varied manure rates and watering intervals were investigated at the Department of Crop Science, University of Nigeria, Nsukka. The treatments included three accessions of Moringa (Awo-Anaekpa, Idere and Kano), three pig manure rates (0, 10 and 20 t/ha) and three watering intervals (3, 4 and 5 days). These were laid out as 3 x 3 x 3 factorial in a completely randomized design, replicated three times. Results showed that seeds of Awo-anekpa accessions had the highest cumulative emergence percentage (97%) and number of emerged seedlings. Plant height and stem girth at 3 months, and number of leaves at 2 and 3 months, after treatment application were higher in Awo-anekpa and Idere accessions than in Kano accession. The leaf proximate composition showed that Idere accession accumulated the highest ash (7.6%) and crude fibre (11.9%). Awo-anekpa contained the highest carbohydrate (41.1%) an...
Evaluation de la croissance et de l'etat nutritionnel des feuilles et des racines de Moringa Oleifera L. en fonction d'amendements organo-mineraux en region tropicale humide Cette etude a ete initiee dans le but d'evaluer l'influence des engrais organo-mineraux sur la croissance et la composition minerale des organes de Moringa oleifera. Trois doses de fumier de vache, trois doses d'engrais mineral et deux doses combinant l’engrais mineral au fumier de vache ont ete comparees. Au cours des deux premieres annees de l'experimentation, des echantillons de feuilles et de racines de M. oleifera ont ete analyses au laboratoire. Les resultats ont revele que les engrais mineraux ont ameliore les proprietes chimiques du sol, a l'exception du pH. Il ressort apres analyse des parametres vegetatifs que le meilleur developpement est obtenu avec la dose 125 kg d'engrais mineral par hectare. Cependant, la composition minerale de Moringa oleifera a ete amelioree par ...
Purpose: An experiment was conducted to study the effect of fertilizer types and rates on the production of moringa in Ogbomoso on the Teaching and Research Farm of Ladoke Akintola University of Technology, Ogbomoso, in 2012 and 2013 planting seasons. Methodology: The experimental design was randomized complete block design with 3 replicates. Nine treatments were used. The treatments were no fertilizer, 400 kg/ha NPK, 600 kg /ha NPK, 800 kg/ha NPK, 1000 kg/ha NPK, 2.5 t/ha tithonia compost, 5.0 t/ha tithonia compost, 7.5 t/ha tithonia compost and 10.0 t/ha tithonia compost. The land was prepared by ploughing and harrowing after the pre cropping soil sampling to determine the physical and chemical properties of the soil. Data collected were plant height, number of leave/plants, dry matter yield, fruit and seed yield components, biomass proximate and elemental compositions. The analyses of variance done were on the data collected and means were separated using Duncan’s Multiple Range ...
