In April or May, as soon as the rice crop has been cut, the field is prepared for planting sugar cane. The soil is first drained of its superfluous moisture, and, if the ground be loose, it is generally ploughed several times. Heavy soils, instead of being ploughed, are treated by the Reynoso method. This consists of digging deep ditches to carry off the subsoil water and to supply irrigation water later on. The plot is then divided by cross ditches into pieces about one-sixth of an acre in size and finally the furrows for the seed are dug. These furrows are generally thirty feet long, from twelve to eighteen inches wide, twelve or fifteen inches deep and four or five feet apart. The earth displaced in digging is piled up between the furrows. Thus prepared, the field is left exposed to wind and sun for about six weeks and at the end of this period the heavy wet clods have crumbled into a gray or light-brown powder. During the drying-out process the grass has to be removed repeatedly, and in case of rain, the soil that is washed down into the furrows is thrown back upon the ridges to prevent the furrows from silting up. The hard bottom of the furrow is loosened or square holes are dug in it and filled with loose soil. Part of the earth on the ridges is thrown into the furrow and the field is then ready for planting. [Illustration: SUGAR CANE AFFECTED BY THE SEREH, JAVA] [Illustration: SEEDLING CANES, JAVA] Before the outbreak of the sereh, seed for new plantations was obtained exclusively from tops of ripe cane, but when the disease became prevalent, it was found that cuttings taken from sereh-infected cane gave diseased yields, while cuttings from cane grown in districts not affected by the sereh produced cane that did not suffer so greatly from the disease. At the beginning of the trouble, cuttings from outside healthy districts were used, but as the disease spread, the demand for sound cuttings increased while the sources of supply became fewer. Finally, plantations were established in remote districts free from disease and they were carefully quarantined. Here seedlings were grown from young cane cut at full length, and in this way sound seed was obtainable at all times. Formerly, seed was only to be had in the grinding season, which frequently occasioned delays in planting. The new plan not only enabled the cane growers to stamp out the sereh, but even after the disease had been practically eradicated it was continued because of its manifest advantages.
