Abstract
Aim:
The aim of the present study was to evaluate the effect of different
vermicompost application rates on growth, protein and chlorophyll content in
leaves of Moringa oleifera under water stress in a greenhouse experiment.
Methodology: Soil samples and seeds were collected and
characterized. Seedlings grown in a greenhouse in polyethylene bags with 4 kg
of soil were subjected to water stress. After 90 days, agronomic variables,
chlorophyll and protein content and peroxidase activity were estimated for
each treatment and each condition in Moringa oleifera. ????
Results:
The results showed that under non-water stress conditions, the levels of
vermicompost at a fertilization rate of 500 kg N ha-1 resulted in
a significant increase in chlorophyll content, as compared to unamended soil.
However, under waterlogging conditions, there was a significant difference
between control and vermicompost treatments.?? ???
Interpretation: The results indicated that addition of
vermicompost to soil improved the growth and photosynthetic rate of Moringa
oleifera under stress-free and water-deficit conditions. However, protein
content only increased significantly when vermicompost was added at a
fertilizer application rate of 500 kg N ha-1 both under
waterlogging and deficit conditions.?? ??????
