Abstract
Mixed over sole cropping is advantageous under the rainfed conditions in Pakistan. This avoids risk of complete crop failure and may returns higher income. The study aimed to investigate appropriate seed-rates combination for wheat-Brassica as mixed- or intercropped in rainfed conditions. Experiments were conducted at National Agricultural Research Center (NARC), Islamabad Pakistan during winter 2004-05 and 2005-06 using 10 treatments for wheat and Brassica as sole and mixed- or intercropped with 100 and 5 kg ha-1 for sole crop and 100 kg ha-1 for wheat with 40, 50, 60, and 70% lower than the recommended for Brassica. Sowing was done in 3rd week of October each year, in lines spaced 30cm. Fertilizer was applied N 48, P2O5 34 and K2O 18 (kg ha-1). Brassica was manually removed for fodder at flowering. Seed rate (SR) significantly (p
