Book excerpt: Field studies were conducted for three years to examine the effect of different plant populations combined with mineral nitrogen fertiliser on nitrogen relationship of maize (Zea mays L.) and beans (Phaseolus vulgaris L.) when planted intercropping system. Two wxpermients were conducted in the University of East Anglia, Norwich, United Kingdom, in 1988 and 1989, and the third one in Petrolina, Pernambuco Brazil, in 1990. Mineral nitrogen fertilizer was wery efficient in increasing total biomass yield of maize in all three experiments, but there was no further increase beyond 50 kg N/ha. In the first year, maize reproductive yield was not significantly affected by either bean plant population or mineral nitrogen fertiliser as compared with sole cropping. However, for intercropped bean yield, there was a positive interaction of nitrogen fertilizer and increasing bean population as a result of higher number of pods per plant. In the second year, reproductive yield of maize was significantly lower in intercropping ans weight per individual cob was the yield component most affected; there was no significant difference between intercropping in the same row and intercropping in alternate rows. Weight per individual cob was the yield component most affected. Although nitrogen fertiliser did not whow significant effect of either crop, even at a higher maize plant population, yield of intercropped beans was slightly higher in same row cropping system with nitrogen fertilizer application, which was (...).
