Abstract
A field study was conducted to determine the influence of four N levels i.e., 0, 60, 120, 180 kg ha"' on four cotton-legume intercropping systems. The results showed that all the intercropping systems responded significantly to N fertilization and produced maximum harvests at 120 kg N ha-I. Compared to monoculture cotton, the highest and significant yield produced by cotton + mungbean system was statistically parallel to cotton + blackgram but different from cotton + pigeonpeas system. Both components of the intercropping systems behaved differentlyto the applied fertilizer nitrogen. Under the intercropping systems studied, cotton produced higher yields upto 120 kg N h44, whereas legumes especially pigeonpeas performed efficiently upto the supply of fertilizer N at 180 kg ha-1.
