Analisis Stabilitas Daya Hasil Varietas Kedelai di Lahan Sawah Kabupaten Madiun, Jawa Timur

The Stability of Soybean Yield Analysis in Wetland of Madiun District, East Java. Adaptive highyielding varieties are the most important component technology to increase the productivity of the crop. The fieldassessment to find out the yield stability was conducted in six locations (Sub-districts: Saradan, Pilangkenceng,Madiun, Balerejo, Mejayan, and Sawahan) in Madiun District of East Java, during the late dry season 2012. Thefour soybean varieties - Argomulyo, Anjasmoro, Kaba, Burangrang - were tested using a randomized block designwith three replications in each locations. The analysis result for the yield stability, using a method by AMMI(Additive Main Effects and Multiplicative Interaction), showed that the Anjasmoro was recognized as a stable andwide adaptation variety. The other analysis result showed that Argomulyo was adapted in Sawahan andPilangkenceng Subdistrict. Also, Burangrang was adapted in Balerejo and Mejayan Subdistrict. In contrast, Kabawas less adapted in all tested locations
