A field study was conducted during rabi season, 2016-17 at the Instructional-Cum-Research Farm of Assam Agricultural University to investigate the potential of nutrient for maize grown as a food cum fodder purpose. The treatment consisted of eight crop management practices viz., Grain crop at 60 cm x 30cm (T1), Fodder crop at 30 cm x15 cm (T2), Fodder cum grain crop at 30 cm x 30 cm with removal of alternate rows at knee-high stage for fodder (T3), Fodder cum grain crop at 30 cm x 30 cm with removal of alternate rows at tasseling stage for fodder (T4), Fodder cum grain crop at 30 cm x 30 cm with removal of alternate rows at milking stage for fodder (T5), Fodder cum grain crop at 30 cm x 15 cm with removal of alternate rows at knee-high stage for fodder (T6), Fodder cum grain crop (30 cm x 15 cm) removal of alternate row at tasseling stage for fodder (T7), Fodder cum grain crop at 30 cm x 15 cm with removal of alternate rows at milking stage for fodder (T8) and two levels of fertilizer viz., F1: 100% of RDF and F2: 150% of RDF. Crop management practice T1 recorded the highest values for all cob parameters, N, P and K uptake. The highest grain yield being 34.21 q ha-1 and was produced from T1 which was at par with crop management practice T6, T7 and T8. However, green fodder yield (164.04 q ha-1) and crude protein yield (3.11 q ha-1) was found to be highest in crop management practice T2. Among the fertilizer levels F2: 150% of RDF recorded the highest cob parameters, grain yield, green fodder yield, crude protein yield and nutrient (NPK) uptake of maize.
