Abstract:

The field experiment was conducted at the Department of Plant Pathology SHUATS during the rabi season, to investigate the “Effect of intercropping on purple blotch (Alternaria porri) of onion (Allium cepa L.)” a legume intercrops evaluated were. Chickpea (Cicer arientinum), pea (Pisum sativum), lentil (Lens esculantum), french bean (Phaseolus vulgaris), cluster bean (Cyamopsis tetragonoloba), the efficacy of the legume intercrops in reducing the foliar disease was compared to a fungicide carbendazim (0.1%). each legume crop was intercropped with onion variety (Nashik red N- 53) purple blotch development were determined until physiological maturity. Legume and bulb yields were also determined at harvest. French bean was the most effective legume intercrop in reducing purple blotch incidence by up to 49.1 % and chickpea was most effective legume intercrop in increasing plant height (46.83), weight (35.53 gm) and size (5.20 cm) of onion bulb. Although intercropping onion with legume reduced bulb yield, it improved the gross return per unit area. The disease occurrence in intercrops was also recorded as a result Powdery mildew and Alternaria blight diseases were occurred in pea, Alternaria leaf spot in french bean, and disease vascular wilt in both lentil and chickpea crops was recorded. The results showed that intercropping onion with legume could be beneficial in reducing foliar disease and improving gross return per unit area. However, further studies are necessary to determine the optimal spatial arrangement of onion and legume intercrops in foliar disease management.
