Abstract
A study on different wheat-based intercropping sy.stems in relation to nitrogen management was conducted at the University of Agriculture, Faisalabad during the year 1999-2000 on a sandy clay loam soil. The experiment comprised three intercropping systems viz. wheat + canola, wheat + Methera and sole wheat while nitrogen levels were 0, 100, 150 and 200 kg ha", Wheat was planted in 100 cm apart 4-row strips with 15 cm space between the rows of each strip. The intercrops were grown in the vacant space between the wheat strips. Various yield components of wheat such as number of spikes m", number of grains spike" and grain yield ha'! were not affected by the various intercropswhile different nitrogen levels had significant effect on these parameters. However, the frain yield did not increase significantly beyond the level of 150 kg N ha", The maximum net income of Rs. 50170.17 ha' with a benefit cost ratio (BCR) of 4.03 was obtained from wheat + canola intercropping at 100 kg N ha" against the minimum income ofRs. 25908.73 ha'! with BCR of2.97 from wheat alone with no fertilizer application. Key words: agro-economic efficiency, nitrogen management, wheat-based intercropping systems
