NITROGEN REQUIREMENT OF BARNYARD MILLET (ECHINOCHLOA-FRUMENTACEA) PLUS PULSE INTERCROPPING SYSTEMS

A field experiment was conducted during rainy seasons of 1990-92 to st udy nitrogen need of barnyard millet [Echinochloa frumentacea (L.) Lin k] + pulse intercropping system. Three levels of nitrogen (50, 75 and 100% of recommended dose) were tested in barnyard millet intercropped with each of horsegram [Macrotyloma uniflorum (Lam.) Verd.], rice bean [Vigna umbellata (Thumb.) Ohwi & Ohasi] and Frenchbean (Phaseolus vul garis L.). The highest barnyard millet-yield equivalent (30.11 q/ha) w as obtained in barnyard millet + ricebean intercropping with 75% of re commended N. The land-equivalent ratio (1.40) was also found higher in the same treatment compared with other treatments.
