Abstract
A field experiment was conducted at the Instructional- cum- Research Farm of Assam Agricultural University, Jorhat, Assam during the rabi season of 2017-18 and 2018-19. The experiment was laid out in factorial randomized block design with treatment combination of three fertility levels (60:40:40 kg NPK ha-1, 90:60:60 kg NPK ha-1 and 120:80:80 kg NPK ha-1), three paired row spacing, 55 cm x 25 cm, 65 cm x 25 cm,75 cm x 25 cm with two methods of sowing (Normal sowing and paired row sowing) and replicated thrice. Results revealed that the growth, yield attributes and yield were recorded with higher levels of fertility in maize and toria crop during both the years. Similarly paired row intercropping of 65 cm x 25 cm recorded significantly highest yield attributing characters, grain and stover yield of quality protein maize and toria along with significantly higher maize equivalent yield. Highest uptake values were recorded under 120:80:80 kg NPK ha-1 during both the year. In case of nutrient uptake by maize and toria crop in quality protein maize, Also NPK uptake by maize and toria crop were significantly higher due to paired row spacing of 65 cm x 25 cm for both the years.
