Studies on the effect of TiO2 nanoparticle on yield attributing traits of mung bean (Vigna radiata L.)
Keywords:TiO2 nanoparticle, mung bean, yield attributing characters.
AbstractThe present project revealed the impact of TiO2 nano materials on yield attributing characters in mung bean in India as well as West Bengal. Six treatment combinations (0, 10, 20, 30, 40, 50 ppm) included control of TiO2 nanoparticle were evaluated for their comparative performance in the field condition following Factorial Randomized Block Design with 3 replications using three varieties of mung bean viz. Panna, Sonali and IPM 23. Differential varietal effect in the present investigation was highlighted as response to different treatments of TiO2 nanoparticle. Low to high concentration of nano TiO2 showed maximum positive response for the characters like days to 1st flowering, days to 50% flowering, plant height, number of clusters plant-1, number of pods cluster-1, pod length, biomass, yield plant-1, low concentration for number of primary branches, leaf area, 100 seed weight, low to medium concentration for number of secondary branches, pod width, low to very high concentration for number of pods plant-1, number of seeds pod-1 and medium to high concentration for weight of seeds pod-1. Cv. Panna was found to be most
responsive to produce desirable result with TiO2 nano treatment for the characters days to 1st flowering, days to 50% flowering, weight of seeds pod-1, biomass and yield plant-1; similar results may be achieved in cv. Sonali for the characters with TiO2 treatment for plant height, number of pods cluster-1, leaf area, number of seeds pod-1.
