Lime, cobalt and molybdenum effects in peanut

Two field experiments were conducted to study the effects of lime, cobalt and molybdenum on peanut yields. Seed treatments (cobalt, molybdenum, cobalt + molybdenum and no treatment) were applied in two peanut cultivars (Tatu and Tupã) grown in four rates of lime (0, 4, 6 and 8 t/ha). Peanut yields were increased by liming owing to increase in the number of grains and grain yield per pod. The highest pod yields were obtained in pH (CaCl2 0.01M) 5.0, exchangeable calcium in the soil of 23.5 mmol c/dm³ and base saturation of 50%. Cobalt and molybdenum had no effect on peanut yields. Although Tupã yielded more shelled peanuts, grain yields were similar in these cultivars.
