Effect of Date of Sowing and Plant Spacing on Mungbean Diseases with Reference to Mungbean Yellow Mosaic Virus

摘要

In field trial to note the effect of planting time and spacings on mungbean yellow mosaic, root rot and leaf crinkle, early sown (12.07.99) mungbean attracted more (18.02%) mungbean yellow mosaic virus as compared to late sown (12.80%) in cultivar K-851. Similarly the disease incidence was 18.02%, 11.86%, 9.48% and 9.33% at row to row plant spacing of 25, 30, 37.5 and 45cm, respectively. The incidence of leaf crinkle and root rot increased with advancing date of sowing. However, yield decreases withadvancing date of sowing.
