Abstract
The study was conducted at Punjab Forestry Research Institute, Faisalabad, Pakistan. It examined the effect of Eucalyptus camaldulensis on yield of agricultural crops after reducing the tree density. E. camaldulensis was planted in 1993 at three different spacing; 6' x 6', 6' x 10', 6' x12'. In 1995 alternate rows of plants were removed to increase the spacing; 6' x 12' meters (rn) (Treatment 1;T1), 6' x 20' m (Treatment 2;T2), 6' x 24' m (Treatment 3; T3) and a plot without trees was retained as control (Treatment 4; T4). Wheat and maize were intercropped during June and September from 1995 to 1997. Each treatment was replicated thrice The yield of wheat grain, wheat straw and maize crops was measured from1995 to 1997 using 1m 2 quadrate. The yield of agricultural crop was high in T4. The yield of wheat grain and straw was high in T2 and T3 as compared to Tt. The yield of maize fodder was not different between T1, T2 and T3. Key words: Eucalyptus camaldulensis, wheat yield, maize fodder yield, tree density
