Abstract

A study was conducted to determine the effectiveness of drip irrigation in the production of burley and dark fire-cured tobacco. Burley and dark fire-cured plots were treated as separate experiments; TN 90 was the burley variety and NL Madole was the dark variety. A randomized complete block with three replications was used for each study. Plot size was four rows, with data collected only from the two middle rows of each plot. Water used was from the city water source. Lay flat tubing was placed between each replication; with drip tape placed the length of each row near the base of the plants. A water flow meter was used for each plot to determine the amount of water each plot received and a ball value so that it could be irrigated as a separate event. Burley plots were transplanted on June 4th and dark plots were transplanted on June 7th, with irrigation withheld from all plots approximately six weeks following transplanting. After this period, irrigation was applied by the following treatments: 1) Check plot with no irrigation; 2) a weekly minimum of 2.5 cm of water, including incident rainfall with drip tape placed along the rows; 3) application of 2.5 cm of water every ten days, including incident rainfall with drip tape placed along the rows; 4) application of 2.5 cm of water every ten days, including incident rainfall with drip tape placed down every other middle row; 5) irrigation applied as indicated by available soil moisture measured by sensors, with drip tape down each row. Irrigation treatments continued until the dark plot was harvested on September 11th and the burley plot on September 10th.
