Evaluation on feasibility of seed is carried out at the breeding level in Nagekeo Regency during 1 ( one ) year (2015 ) and the result of F1 is evaluated in the agro-ecosystem of wet rice field ( Nagekeo District ), dry land ( Kupang district ) and land of Ahuklean (Malaka district ). The results shows that: a) the average productivity of the F1 Bima 20 URI seeds is 3,200 kg/ha, however, if the price of seed was IDR 27,500/kg, the breeder will get a profit of IDR 20,496,000. b) Corn productivity of the F1 Bima 20 URI which was planted in agro-ecosystem of irrigated wet rice field, dry land and land of ahulean respectively 6.75 tons/ha, 5 tons/ha and 3 ton/ha with a profit of each respectively of IDR 22,220.00 and IDR 15,220,000, IDR 8,850.00; c) The value of R/C ratio of the seed breeder of the F1 Bima URI 20 was of 2.63 and the value of R/C ratio of the hybrid Bima URI 20 in various agroecosystems of 4.65, 3.18 and 2.81. Thus, the seeding and development of the hybrid corn Bima URI 20 in NTT is reasonably to be carried out.

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
