Mungbean is one of the most desired legume of vegetarians, its wide cultivation across many parts of Africa, South East Asia including India is driven by its huge demand across many parts of the world. However, its cultivation is suffering in all these regions due to Yellow Mosaic Disease (YMD) caused by Mungbean yellow mosaic virus (MYMV). Hence present investigation was carried out to understand the effect of date of sowing on incidence of MYMV in mungbean during Kharif 2016-17. Mungbean was

... own at weekly interval of Standard Meteorological Week (SMW) starting from 22 nd SMW up to 7 weeks. First sowing was done on 30 th May (22 nd SMW), followed by 6 th June (23 rd SMW), 13 th June (24 th SMW), 20 th June (25 th SMW), 4 th July (27 th SMW) and last was on 11 th July (28 th SMW). Observations on incidence of MYMV at each date of sowing and yield parameters recorded were subjected to statistical analysis. The results of revealed that, most suitable date of sowing with maximum yield parameters was 23 rd SMW (6 rd June) which recorded least MYMV incidence of 4.85 per cent with highest of 9.32 pods/plant and seed yield of 1220 kg ha -1 , followed by 22 nd SMW (30 th May) sowing which recorded disease incidence of 6.84 per cent with 8.92 pods/plant and seed yield of 1093 kg ha -1 . The lowest yield parameters of 6 pods/plant and 112 kg ha -1 seed yield was recorded in the plot sown on 28 th SMW (11 th July) with highest MYMV incidence of 15.15 per cent followed by 27 th SMW (4 th July) sown plot, which recorded on par of 6.2 pods/plant and 116 kg ha -1 seed yield with incidence of 13.60 per cent. Hence from each date of sowing reveals the most suitable date of sowing for mungbean is 6 th June (23 rd SMW), which had lowest MYMV incidence and highest seed yield compared to others.
