Land Preparation
Farmers usually do not perform tillage or
perform a minimum tillage (minimum
tillage). The field work begins with a channel
drainage or paliran every 2 m with a depth of 25-30 cm
and width of 25-30 cm. Farmers who grow cotton will be
monocultures on former crops, making
paliran deeper. In this land crops such as cotton
can produce 4166 kg / ha. To inhibit
pertumbuan grass, land dututup with mulch before
cotton is planted.
Seed
Cotton seed varieties used are ISA 205
berkabu-Kabu as much as 15-20 kg / ha. Seed cotton obtained
of managers, namely PT Breadfruit. Soybean seeds are planted
Wilis are the varieties of 60-80 kg / ha. Farmers who
plant the seeds of green beans using 20-25 kg / ha.
Before planting, seed crops are treated with
insecticide seed contain active asefat.
Planting
Cotton and food crops grown in different ways.
Soybeans and green beans grown in dispersed,
whereas at the edge of cotton with ditugal paliran at 3-7
days after planting soybeans. After five hours of soaking, the seeds

Fertilization is done by putting fertilizer on
near the plant. Fertilization is done by first
provide TSP 100 kg and 25 kg urea / ha. Second fertilization
performed 6 weeks after planting or after harvest cotton

areas of high rainfall, the first fertilization
performed by giving 100 kg of TSP, 100 kg of KCl, and 50
ZA kg / ha; and fertilization both by providing 100
kg urea / ha. Typically, the second fertilization performed in
dry conditions, so that the necessary pengocoran water.
Pest / Disease
Before the soybeans are harvested, the cotton crop is still in the phase
vegetative growth. Intensive care after
soybean crop is harvested or when the cotton into
generative growth period, which began the formation of
flowers and fruit.
Cotton farmers in Brebes not know a lot of pe-
ngendalian integrated pest. In general, farmers
using insecticides to control pests
manner and timing of spraying is less precise.
They mix several types of insecticides and
spray the caterpillars are already big, so it is not effective.
Thus, in one season can be done
insecticide spraying of 6-10 times.
In addition to leaf-eating caterpillars, flower buds and fruit
cotton rat were also attacked. At the beginning of growth,
rat attack by cutting the plant, while
right during generative growth by eating
young fruits. Farmers have not applied the technique sedi-
Dalian effective against pest rodents.
Harvest and Postharvest
Soybeans are harvested when the leaves have yellowed and fall
and pods had turned yellow and dry. Green beans
harvested when 60% of pods have been black. Drying
soy beans made until the water content of 12%. Cotton is harvested
if 50-60% of men have broke perfectly. Delay
harvest time will degrade the quality of cotton fiber.
RESULTS AND DISCUSSION
Table 1 shows that some of the means of production
farmers who used excess, for example the use of seed
rice and soybeans, insecticides, and herbicides. Standard dosage
rice seed is 25 kg, 30 kg of soybean (by way ditugal),
In the cropping pattern of intercropping cotton with soy and
green beans, cotton is planted on the edge paliran so it does not
interfere with soybean and green beans. This
shown by the results of soy and green beans on top
average, ie more than 600 kg / ha for soybean and more
of 400 kg / ha for green beans (Table 3). Thus,
If farmers grow cotton would receive an additional pen-
income. Cropping pattern of rice a year - cotton intercropping
followed by soybeans and green beans can provide
Rp3.384.805/ha revenue with B / C ratio of 0.385 (Table 4).
