Daftar Isi:
- The research was conducted to study the effects of leaflets reduction to the physiological activities, growth and yield of soybean varieties. Several previous studies provide information that reduction of leaf decreased the crop yields. In soybean, the effects of the reduction of leaflets to the physiological activities, growth and yield still unknown. Therefore, this research was urgently required. The research was conducted in August-November 2010, at Tridharma Garden, Faculty of Agriculture, University of Gadjah Mada, Banguntapan, Bantul, Yogyakarta, at 113 m above the sea level with the regosol soil type. The research was conducted in split plot design with three replications as blocks. The main factors were the reduction of leaflets, namely without the reduction and the reduction of one, two and three leaflets. While the sub factors were the soybean varieties, namely Wilis, Sinabung, Argomulyo, Grobogan and Ijen. The observations were done on several variables such as physiological activities, growth, yield components and yield of soybean. Data were analyzed with analysis of variance (ANOVA) at 5% level, and continued with Duncan's Multiple Range Test (DMRT). The results showed that reductions of a leaflet enhance the specific leaf weight, stomatal conductance, photosynthetic rate and numbers of pods of five soybean varieties were tested in this study. Sources owned by the five soybean varieties used in this study has not been reached the optimal level, so that the reduction of leaflets actually had a negative impact on the growth and yield of soybean.
