Title: Growth Response of Upland Rice (Oryza Sativa L.) Varieties to Nitrogen and Seed Rates in the Northern Guinea Savahah.
Abstract: Field experiments were carried out at the Institute for Agricultural Research (IAR) farm at Samaru during 2011 and 2012 rainy season. The treatments evaluated were two rice varieties (NERICA 4 and 8), three rates of nitrogen (0, 65 and 130 kg N ha -1 ) and three seed rates (30, 60 and 90kgha -1 ). The treatments were factorially combined and laid out in a Randomized Complete Block Design (RCBD) replicated three times. Results obtained shows that NERICA 4 produced taller plants than NERICA 8. Application of nitrogen up to 65 kg N ha -1 significantly increased plant height, and leaf area index, however, crop growth rate and relative growth rate responded to applied 130 kg N ha -1 . Plant height was not significantly increased beyond seed rate of 60 kg ha -1 . Based on this study it can be concluded that both NERICA varieties can be sown at the rate of 60 kg ha -1 with application of 65 kg N ha -1 . Key words: NERICA, Nitrogen, Seed rate, Northern guinea savannah
