Abstract

An experiment to know the effect of plant row and the defoliation of maize leave to the yield of maize, growth and the yield of peanut was conducted in peanut field, socah district, Bangkalan. A 2x4 factorial with three replications was arranged in split plot design.  The first factor was plant row of design, i.e. single and double row of plant. The second factor was the defoliation of maize leave, i.e. 0% (the control), 30%, 40% and 50% of the defoliation of maize leave. Result of the experiment indicated that the defoliation of maize leave at 40% and 50% reduced the yield 38,70% and 39,40% of dry weigth of plant, 6,80% and 15,10% of 100 seed weigth.  The interaction treatment only gave significant effect in the maize-ear dry weigth; defoliation of maize leave very reduce the maize-ear dry weigth, especially in the double-row of plant. Defoliation of maize leave effect growth, component of yield and yield of peanut.  The row plant design effect to the leave area, component of yield and yield except to weigth of 100 seed. The double row of plant compare to single row of plant have dry weigth of pod, sum of pod, sum of seed and dry weigth of seed plant significant.  Increment of defoliation of maize leave significant to increase sum of branch, plant dry weigth, sum of leave, pod dry weigth, sum of pod, sum and dry weigth of seed of plant.
