 For 1956 there were 869 acres of non-irrigated tobacco
producing 1121 pounds of tobacco per acre that sold for an
average of 48.9 cents per pound. The acreage of irrigated
tobacco had increased to 524 acres and the irrigated tobacco
produced an average of 1420 pounds per acre that sold for
an average of 51.1 cents per pound.

 The acreage irrigated in 1956 was 37 per cent of the total
acres. The irrigated crop produced 44.4 per cent of the total
gross value in 1956.
 It is believed that the above mentioned figures are very
significant when factors such as, variabilities in soil type,
cropping practices, fertilization rates, plant spacing and the
actual application of the irrigation water are taken into con-
sideration.
 This trend has been experienced in several other countries
and serves to point out the benefits of irrigation as a regular
production practice.
 In summary, irrigation, properly applied, blended with good
varieties, fertilization, fumigation, cultural practices and when
good harvesting and curing practices are followed is bene-
ficial to the farmer. Figures 22, 23, and 24 show some irri-
gation practices.

 INSECT AND PEST CONTROL
 Insects which attack flue-cured tobacco also attack many
other major crops. A detail description may be found in
