Assessment of green gram varieties for better yield in Nagapattinam District of Tamil Nadu

Green gram (Vigna radiata) is commonly known as Moong an important pulse crop in India and more than 70 per cent of world’s green gram production comes from India. In Nagapattinam, farmers sow the moong after harvesting of rice crop during summer. The present study was conducted during summer of the year 2017 in three villages of Nagapattinam district to assess the suitable variety of green gram. Five farmers’ field were randomly selected and sown two high yielding improved varieties of green gram namely CO 8 and LGG 460 with five replications with one check variety already grown by the farmers. The data like average plant height, number of branches, pods/plant, grain/pod, disease incidence (%), Synchronization, 100 seed weight and pod yield (q/ha) were recorded during investigation. Among all the varieties assessed, variety CO 8 proved to be the best with highest number of pods/plant (31.2) and minimum incidence of yellow mosaic disease of 4.2 per cent resulting in the highest yield of 7.35 q/ha followed by LGG 460 with disease incidence of 5.6 per cent, 28.3 pods/plant and yield of 6.95q/ ha. Hence, it was inferred that CO 8 variety of green gram proved better followed by LGG 460.
