Abstract
Intercropping is an attempt to plant several types of crops on the land at the same time, arranged in such a way in a row of plants. Planting in this way can be done on two types of plants that are relatively different old. The application of Rice-Corn intercropping was carried out in Playen District of Gunungkidul. Rice seed was used Sidenuk and Inpari 42 varieties then planted at distance of 40 cm x 20 x 12.5 cm (Tajarwo 2:1). The corn seed used Pioneer 35 and they are planted at 60 cm x 25 cm. The purpose of this research is to examine the application of intercropping rice-corn compared to monoculture cultivation on the aspects of soil nutrients status, affects intercropping on both crops yield and feassibility analisys of the intercropping farming on the two different agricultural system. The results of study show that on intercropping pattern rice yield can reach 5.19 to 5.85 ton ha-1 and dry corn shells from 5.43 to 6.28 tons ha-1 and quite profitable with a B/C ratio of 2.68 and R/C ratio of 3.12 compared to rice or corn monoculture planting patterns alone with B/C ratios of 1.24 and 1.88, respectively
Highlights
The cropping pattern is a planting effort on a plot of land by regulating the layout and sequence of plants during a certain period of time including the tillage period and the nonplanting period for a certain period
The cropping pattern in Indonesia, which has a tropical climate, usually is arranged for one year by paying attention to rainfall, especially in areas or land that are completely dependent on rainfall
Along with the development of intercropping patterns began to be abandoned, but nowadays, considering the availability of agricultural land which keeps on narrowing, this mixed cropping pattern is being applied again. [1], said that the Ministry of Agriculture is targeting an increase in production of rice, corn and soybeans, by increasing the planting area through various breakthroughs
Summary
The cropping pattern is a planting effort on a plot of land by regulating the layout and sequence of plants during a certain period of time including the tillage period and the nonplanting period for a certain period. The condition of the land area that is getting narrower and the cost of production is increasing forcing farmers to innovate so that their income in farming can fulfill their daily needs. To maximize land use and increase farmers' income, the Agricultural Research and Development Agency implements cultivation using mixed or intercropping techniques. The technique of planting with an intercropping pattern is not new in the world of agriculture in Indonesia, since ancient times we have implemented this pattern. Along with the development of intercropping patterns began to be abandoned, but nowadays, considering the availability of agricultural land which keeps on narrowing, this mixed cropping pattern is being applied again. [1], said that the Ministry of Agriculture is targeting an increase in production of rice, corn and soybeans, by increasing the planting area through various breakthroughs. Its hoped that there will be no competition for land use between rice, corn and soybean commodities, but instead of it will increase the population of the three plants (rice, corn and soybean)
