Abstract
The study was conducted in South Central Timor and North Central Timor in the month of March to May 2017, the aims are the determinate the additional amount of money value of feed crops planted as a hedge row in vegetative conservation than without conservation, and the value of money of corn plants grown in the hedge row cultivation land for five years. Data were collected through interviews and field observations. The results showed that: (a) Production of biomass feed is grown as a hedge row to increase over time utilization and production will be stable after the fourth year by 25 t ha-1 year-1, (b) The relationship between biomass production and utilization of time to form a linear line with equation y = 6032.63 x - 592.6. (c) The relationship between biomass with time concession revenue line shape with the linear equation Y = 2,021,458.37x-2,444,254.57, (d) Hedge row has the potential to supply cattle feed about 2-3/6 months fattening or 4-6 fish/year, (e) Gross margin vegetative conservation concession for five years at IDR 50,111,138 ha-1 and without conservation of IDR 20,077,617
Highlights
The cause of the decline in national food production that is felt today is increasingly narrow area of productive agricultural land as a result of function shifts such as conversion of rice fields, in addition to the global issue of increasing land degradation
Vegetative conservation is commonly planted by farmers in North Mollo Sub district, Timor Tengah Selatan (TTS) Regency that is elephant grass ( Pennisetum purpureum ) planted together with corn in the first year, while farmers in West Miomafo Subdistrict, Timor Tengah Utara (TTU) Regency usually plant calliandra ( Calliandra calothyrsus ), as animal feed
The results showed that 82% of the farmers owned cattle, with a range of ownership of 1 - 6 heads of household -1 and an average of 1.86 heads of households
Summary
The cause of the decline in national food production that is felt today is increasingly narrow area of productive agricultural land (especially on the island of Java) as a result of function shifts such as conversion of rice fields, in addition to the global issue of increasing land degradation (in developing countries). The development of the population of Timor Island is increasing day by day, causing the need for more food with better variety and quality to increase. The challenges in the future will be even more severe because the consequences of population growth can have an impact on the conversion of land from agriculture to housing, industry and other uses, whereas currently East Nusa Tenggara Province still needs to import 3,252 tons of grain, especially rice per year [1]
