EFFECT OF FERTILITY LEVELS ON MAIZE (ZEA-MAYS)-FED CONDITION(LEGUME INTERCROPPING SYSTEM UNDER RAIN)

A field experiment was ocnducted during the rainy seasons of 1986-88 t o evaluate fertilizer application and economics of some locally import ant intercropping systems. Maize (Zea mays L.) was supplied with 50, 7 5 and 100% of the recommanded fertilizer levals, whereas blackgram (Ph aseolus mungo L.) and hoursegram [Macrotyloma uniflorum (Lam.) Verdcou rt] were supplied with 0, 50 and 100% of the recommended fertilizer le vesl in intercroping systems. Though maize yield was decreased when in tercropped with horsegram but generally gave higher maize-equivalent y ield than maize + blackgram system. For obtaining higher net returns, no fertilizer should be applied to blackgram but additional 50% of rec ommended fertilizer to horsegram should be applied in maize + horsegra m intercropping system.
