Green amaranth (Amaranthus viridis) is one of the most popular leafy vegetables<br />

cultivated in Malaysia. The photo-selective netting is an innovative agro-technical<br />

method that can upgrades the conventional net covering to a more sophisticated level.<br />

This method could alter the microclimate and solar radiation as well as protecting the<br />

crops against environmental hazards and pests. This study aims to investigate the<br />

growth performance of green amaranth under different color of photo-selective<br />

netting (control, black and yellow). The pre-harvest and post-harvest parameters that<br />

will be assessed are leaf chlorophyll content, leaf surface area, disease incidence, total<br />

yield, microenvironment analysis and measurement of absorbed Photosynthetically<br />

Active Radiation (APAR). It is expected that this new technology of photo-selective<br />

netting will provide a sustainable solution to increase agricultural production by<br />

improving the productivity and quality of the yield compared to control plants.<br />
