Abstract

Pot experiments and laboratory analysis were conducted to determine the effect of N fertilization and level ofwater table treatments of wet soybean culture on nodule formation and seed yield of soybean. The pot experiment was conducted in Cibungbulang and laboratorium analysis, was at three difforent laboratories: Soil, Agronomy,and Pasture, Bogor Agricultural University, started on August, 1993 up to February, 1994. Three factors to be evaluated, namely varieties (Lokon andLompobatang), N fertilizer applications of0, 140, and280 mgporI (equivalent to 0,25, and 50 kg N ha-I), and the level ofwater tables of(control, -15 cm, -10 cm, and -5 cm below the soil surface).
