In raising rice in the sáwahs, inundation is indispensable till it is nearly ripe. The seed is first sown on a bed prepared for the purpose, about one month before the season for transplanting it, and the plant is during that time termed bíbit. Two methods are in use. According to the first, called úrit, the ears of pári are carefully disposed on the soft mud of the seed bed; in the second, called ng'éber, the separated seeds are thrown after the manner of broadcast in Europe. In by far the greatest portions of the island, the ground is prepared, the seed sown, and the plant removed, during the course of the rainy season, or between the months of November and March. In situations where a constant supply of water can be obtained from springs, rivulets, or rivers, two crops are produced in the course of twelve or fourteen months; but the advantage of double cropping, which exhausts the soil without allowing it time to recover, has been considered as very questionable. If in some situations commanding a supply of water, the earth is allowed to rest after the preceding harvest, during the latter end of the rainy season, and the transplantation made in the months of June and July, it generally yields more profitable crops than the common method of working the sáwah. This, which is termed gádu by the natives, has been recommended by the experience of European planters.
Irrigation is exclusively effected by conducting the water of rivers and rivulets from the more or less elevated spots in the vicinity, and in this respect, differs materially in its process from that of Bengal, for although considerable labour and ingenuity are exercised in detaining, regulating, and distributing the supply, by means of dams, called bandáng'ans, no machinery whatever is employed in raising water for agricultural purposes in any part of the island.
The rice grown on sáwahs, is of two kinds, pári génja and pári dálam. In the former, the harvest takes place four months after the transplantation; in the latter, six months. Pári génja having the advantage of a quicker growth, is therefore often planted when the rainy season is far advanced. Pári dálam is more prolific, and yields a grain of superior quality, comprising those varieties in which the ears are longer and more compound. The varieties of each kind are distinct and permanent.
The subvarieties are very numerous, amounting, with those of kétan, to more than a hundred. Kétan is a distinct variety, with very glutinous seeds, seldom employed as an article of food, except in confections, cakes, and the like. Of the varieties of the pári génsha, mentik and anchar bántap are preferred. Of the pári dálam, those of krentúlan and súka nándi are most esteemed, being remarkably well flavoured and fit for keeping. S'lámat jáwa yields also rice of good quality. The bearded kinds of pári are always preferred for keeping, as the grains do not readily fall off. Near Súra-kérta, the principal native capital, close to the site of the former capital Kérta-súra, there is a peculiar tract inundated by water from a fountain at Píng'gíng, which is said to produce a grain of very superior flavour, from which the table of the Susuhúnan is supplied. Súka nándi is the kind uniformly preferred for these plantations.
For pári gága, whether in high or low situations, the ground is prepared by ploughing and harrowing, and the seed is planted after the manner called setting in some parts of England. The holes are made by pointed sticks, called pónchos, and into each hole two seeds are thrown. Only careless husbandmen, or those who cannot procure the requisite assistance in their labour, sow by broadcast. In high situations the earth is prepared before the rains commence: the seed is sown in the months of September or October, and the harvest takes place in January and February following. Gágas of low situations are planted about a month after the harvest of the sáwah is got in, and frequently receive temporary supplies of water from a neighbouring rivulet. In high situations, to which water cannot be carried, they are sufficiently moistened by the first rains of the season. During their growth, they receive several hoeings from the careful husbandman.
As the grain ripens, an elevated shed is frequently erected in the centre of a plantation, within which a child on the watch touches, from time to time, a series of cords extending from the shed to the extremities of the field, like the radii of a circle, and by this cheap contrivance, and an occasional shout, prevents the ravages of birds, which would otherwise prove highly injurious to the crops. These little elevated sheds in the interior, and particularly in the district of Bányumás, are very neatly constructed of matting.
The reapers are uniformly paid, by receiving a portion of the crop which they have reaped: this varies in different parts of the island, from the sixth to the eighth part, depending on the abundance or scarcity of hands; when the harvest is general through a district, one-fifth or one-fourth is demanded by the reaper. In opposition to so exorbitant a claim, the influence of the great is sometimes exerted, and the labourer is obliged to be content with a tenth or a twelfth.
The grain is separated from the husk by pounding several times repeated. The first operation is generally performed in wooden troughs, in the villages near which it grows, and before it is brought to market. The pári being thus converted into bras or rice, afterwards receives repeated poundings, according to the condition or taste of the consumer.
With the exception of the rice raised in sáwahs, all other produce is cultivated on dry grounds, either on the sáwah fields during the dry season, or on tégal land, at all times exclusively appropriated to dry cultivation. The principal article next to rice, as affording food to man, is maize or Indian corn, termed jágung. It is general in every district of Java, but is more particularly an object of attention on Madúra, where, for want of mountain streams, the lands do not in general admit of irrigation. In the more populous parts of Java, likewise, where the sáwahs do not afford a sufficient supply of rice, the inhabitants have lately had recourse to the cultivation of maize. It is now rapidly increasing in those low ranges of hills, which, on account of the poverty of the soil, had hitherto been neglected, and is becoming more and more a favourite article of food. In the more eastern districts, it is procured from the inhabitants of Madúra in exchange for rice. It is generally roasted in the ear, and in that state is exposed while hot for public sale; but it is never reduced to flour, or stored for any considerable time.
The zea maize, or common jágung, is a hardy plant, and grows on any soil. In common with every other production of Java it thrives there most luxuriantly; nor is there any reason to believe, that the Javan soil is less adapted to it than that of Spanish America, where Humboldt estimates its produce at a hundred and fifty fold. It is planted in fertile low lands in rotation with rice, and in high situations without intermission, often forming in the latter the chief, if not the only, support of the inhabitants. There are three different kinds, distinguished from each other by their respective periods of ripening. The first kind requires seven months, and is a large rich grain; the second takes only three, and is of inferior quality; and the third, which seems valuable only on account of its rapid growth, ripens in forty days, but has a poor small grain. They may be planted at all seasons of the year; and of the two inferior kinds, several crops are often raised from the same ground within the year.
