    Effects of transplanting date, nitrogen rate and rate of harvest on extending the harvest of flue-cured tobacco

    HAWKS S.N., Jr; COLLINS W.K.; KITTRELL B.U.
    Crops Science Extension Specialists, North Carolina State University Agricultural Extension Service, USA
    In 1974 a test at five on-farm locations was conducted on flue-cured tobacco in North Carolina to measure the effects of three transplanting dates, two nitrogen rates and two rates of harvest on the dates of harvest, yield, quality and concentration...

    Effects of simulated hail damage on yield and value of flue-cured tobacco

    HAWKS S.N., Jr; COLLINS W.K.; KITTRELL B.U.
    Department of Crop Science, North Carolina State University, Raleigh, North Carolina USA
    A simulated hail test was conducted at 11 on-farm locations in North Carolina in 1970-71 to measure the actual damage to flue-cured tobacco yield and value compared to the inflicted damage which was based on the hail adjustment procedure which had...

    Part organic vs all mineral nitrogen fertilization of flue-cured tobacco

    HAWKS S.N., Jr; COLLINS W.K.; KITTRELL B.U.
    North Carolina State University, Agricultural Extension Service, Raleigh, North Carolina USA
    The effects of yield, value, and price per hundredweight from the use of 3-9-9 with 20 percent organic nitrogen compared with all mineral form of nitrogen on flue-cured tobacco are shown. There were no differences in yield, value, or price per...

    Effects of three herbicides on weed control, yield, and vale of flue-cured tobacco

    COLLINS W.K.; HAWKS S.N., Jr; KITTRELL B.U.
    Department of Crop Science, North Carolina State University, Raleigh, North Carolina USA
    Where two cultivations were used, tobacco yield from the three herbicides treatments were similar to that of the control; however, there was a trend for increased yields where a herbicide was used. The numerical increase was greatest for diphenamid....

    Effects of contact and systemic sucker control agents applied in button and early flower stages on yield and value of flue-cured tobacco

    COLLINS W.K.; HAWKS S.N., Jr; KITTRELL B.U.
    Department of Crop Science, North Carolina State University, Raleigh, North Carolina USA
    Tobacco topped in the button stage that received a sequential application of a contact (applied in the button stage) followed with a systemic (applied in the early flower stage) sucker control agent had the same price and tended to, yield more and...

    Comparison of MH-30 and Royal MH-30 on sucker control and yield and value of flue-cured tobacco

    COLLINS W.K.; HAWKS S.N., Jr; KITTRELL B.U.
    Dept. of Crop Science, North Carolina State University, Raleigh, North Carolina USA
    Even though Royal MH-30 was associated with an increased degree of sucker control, there was no increase in yield or value of the tobacco. This suggests that when there is a high degree of sucker control a small difference in sucker growth has no...

    Effects of plant spacing and height of topping at two nitrogen rates on some agronomic-economic characteristics on bright tobacco

    COLLINS W.K.; HAWKS S.N., Jr; KITTRELL B.U.
    North Carolina State University, Agricultural Extension Services, Raleigh, North Carolina USA
    A bright tobacco study was conducted to measure the agronomic-economic effects on yield and value of three leaf numbers (120,000, 150,000, and 180,000) per acre at two leaf numbers per plant and at two nitrogen rates. As the number of leaves per acre...
