Description T-8797
An experiment was conducted at research farm of IARI, New Delhi to study
the change in the microenvironment under different colour shade nets during summer
and rainy season of 2012. Spinach crop was sown under different colour shed nets
such as red, green, black, white along with control (without shed net) during the two
seasons. Different weather parameters such as temperature, relative humidity, wind
speed etc, light intensity, radiation, percentage reflectance, canopy temperature and
moisture were measured at different crop growth stages. Different heat indices were
calculated under different colour shade nets along with control. Result showed that the
light intensity, incoming radiation, canopy temperature, air temperature, wind speed,
soil temperature were found to be lower under different colour shade nets as compared
to the corresponding values under control. However the relative humidity and soil
moisture were found to be higher under colour shade nets as compared to control. The
heat indices were calculated and it was found that different heat indices such as GDD,
PTU, HTU and PTI were higher in control followed by black, green, red and white
colour shade nets in both seasons. The heat use efficiency was found to be more in
different colour shade nets than in control
