Abstract

The study was carried out in the Village Gondang, Sragen Regency Central Java in the dry season (June- October 2009) and in the wet season (October 2009 - January 2010).

Productivity in the dry and in the wet seasons were Inpari 1 (9.2 and 8.4 t/ha), Silugonggo (9.3 and 8.2 t/ha), OM 1490 (9.5 and 8.1 t/ha), OM 2395 (8.9 and 7.7 t/ha) and B11283 in the wet season (8.1 t/ha) dried grain, (iii) productivity in the dry season were higher than in the wet season. The average productivity was different between that in the dry and in the wet season were Silugonggo 1.1 t/ha, Inpari 1 0.8 t/ha, OM 1490 1.4 t/ha, and OM 2395 1.2 t/ha dried grain or decreased of productivity between 8.70 -14.74%, and (iv) Inpari 1 and OM 1490 more preferred of the farmers compared Silugonggo and OM 2395.
