STUDIES ON FERTILIZER REQUIREMENTS AND PLANTING DENSITY FOR MORINGA PLANTS IN NORTH AFRICA
Planting density, Fertilization, Moringa oleifera, Vegetative growth, Pigments contents, Nutrient contents.
The objective of this study was to evaluate the effect of nine planting densities (10, 15 and 20 cm between hills combined with 1,2 and 3 plants per hill), also the effect of fertilizer levels (control, mineral fertilizer : compost (1:1) with Nitrobin, mineral fertilizer and compost (1:1) without Nitrobin, mineral fertilizer: compost (1:3) with Nitrobin, mineral fertilizer and compost (1:3) without Nitrobin on growth and chemical constituents of Moringa oleifera in the open field during two successive seasons 2013 and 2014 at Nubaria Research and Production Station. Effect of fertilizer levels on vegetative growth and chemical constituents of Moringa oleifera plants: The plants treated with mineral fertilizer (control) or mineral fertilizer : compost (1:1 with Bio-fertilizers Nitrobin) gave the highest values of plant height, stem diameter, leaf number, plant weight, leaf area and fresh & dry weights of stems and leaves, in the two seasons. The total carbohydrates, vitamin C, chlorophyll a- b, total chlorophyll, carotenoids and nutrients (N, Ca, Zn, and Fe) increased with mineral fertilizer: compost 1:1 with Nitrobin compared with other treatments.Effect of different planting density on vegetative growth and chemical constituents of Moringa oleifera plants: The obtained results showed that using the 20 cm and 1 plant per hill had a favorable effect on increasing all the growth parameters (Plant height, stem diameter, leaf number, plant weight, leaf area and fresh and dry weights of stems and leaves as well as the content of pigments, total carbohydrates, vitamin C, chlorophyll a- b, total chlorophylls, carotenoids and nutrients (N, Ca, Zn and Fe) in the two seasons comparing with other planting densities .
