Abstract
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.

Corn is the staple food for most of the people of East Nusa Tenggara (NTT)
The tested on the three types of agro-ecosystem in NTT such as : a). agro ecosystem land of wet rice fields where corn is planted after rice harvest in June to October, 2016 in the land of farmers in Oesao village, District of Kupang Timur, Kupang Regency; b)
Based on the results of the analysis on farming activity of corn production of the F1 Bima URI 20 with a wide area of the planting of one (1) hectare can be achieved the row income namely IDR 33,000,000 - while the results of the sale is 1,200 kg with the price per kg of IDR 27,500, from the results of the production of F1 Bima 20 URI of the farmer/breeder will get a profit of IDR 20,496,000
Summary
Corn is the staple food for most of the people of East Nusa Tenggara (NTT). The wide of planting area of hybrid maize in NTT for the last 4 years (20014-20017) has increased every year, such as 36.718, 61,712, 112,026 and 150,223 [1]. The trend of increasing domestic demand for corn has encouraged efforts to increase domestic maize productivity. This increase in productivity was mostly dominated by hybrid maize which has excellent characteristic compared to local maize [2]. With the highly demand for corn seeds in NTT, the availability of source seeds to produce seeds labeled with the below class needs to be held continuously. Apart from freeseeded seeds, the need for hybrid seeds continues to increase.
