Field experiments were conducted on Burley Tobacco grown as a monsoon crop on sandy loam soils of agency area of East Godavari District of Andhra Pradesh (India). The leaf of Burley crop produced in this zone is of a distinctly superior quality having a typical Burley nose with low nicotine and high filling value suitable for meeting export demand. The varieties Burley 21 and Banket A1 performed well under Indian conditions. The Variety Banket A1, an exotic introduction of recent years, recorded an increased yield of 20% over the existing cultivar, Burley 21. Burley tobacco crop planted on ridges during 15th July to 10th August produced higher yields over delayed plantings. High plant density of 31,250 /ha (80 x 40 cm) produced highest yield of Burley 21 over 25,000 plants/ha with a spacing of 90 x 45 cm, and application of 125 N, 50 P2O5 and 50 K2O kg/ha was found to be optimum for realising higher yields. Application of fertilizer by dollop method on the top of the ridge on either side of the plant at a distance of 10 cm at 10 and 30 days after planting proved to be efficient and recorded higher yields. The basal dose of N (50%), P (100%) and K (50%) is to be applied as CAN, DAP, and Sulphate of Potash respectively and the remaining dose of N and K as CAN and Sulphate of Potash as second dose. Among harvesting methods, the customary practice of harvesting the leaf as and when matured by priming method was found to be more advantageous than complete stalk-cut and partial priming + stalk-cut methods for Burley 21.
