ABSTRACT

Rice is staple food for all over the world. Nowadays the production and productivity of rice crop affected by changing climate especially to high temperature and high concentration of ultraviolet-B radiation. This study evaluated the photo protective  potential of ecofriendly chemicals like glycine betaine, ascorbic acid and combination fungicide Nativo (25 WG trifloxystrobin+ 50 WG tebuconazole) with two different concentration under two levels of solar radiation which is 100 and 80% solar radiation to get two levels of UV-B radiation. From diurnal observations of PAR and UV-B radiation revealed that, both are gradually increased from 8am to 12pm. Treatment effect of this experiment showed that under 100% and 80% solar radiation all the chemical treatments  recorded higher height and tiller number  than absolute control. Among chemical treatments Nativo 70ppm could enhance the grain filling period up to 6 days compared to absolute control under both condition which contributed maximum grain yield, it may be due to its ethylene inhibition capacity to decrease senescence and retain greenness in crops.
