A field experiment was undertaken at Regional Agriculture Research Station, Nandyal, Andhra Pradesh during 2017-18 on vertisols under rainfed condition to find out the suitable method of planting to avoid water logging for higher cured leaf yield in bidi tobacco (Nicotiana tabacum L.). The treatments consisted of two planting methods (Ridge method and flat bed method) as one factor and four planting geometry (60 cm x 50 cm, 60 cm x 75 cm, 75 cm x 50 cm and 75 cm x 75 cm) as another factor in factorial randomized block design and replicated thrice.
