Purpose: Coordinated soil richness management innovation fits into the position of resource for poor cultivating on an Afisol in the Guinea savannah zone of Ghana. The research was conducted to determine the effect of seed coating and Burkina rock phosphate on the growth and yield of rice at University for Development Studies in Nyankpala near Tamale in the Northern Region of Ghana. The study aimed is to determine the interaction of Burkina rock phosphate and Triple superphosphate on the growth and yield of rice.Research Method: The experiment was a 2x3 factorial laid in randomized complete block design replicated six times. Factor one consisted of two levels such as, coated rice seed and non-coated rice seed whilst factor two consisted of three levels of (P) phosphate; (Burkina rock phosphate, Triple superphosphate and Non-Phosphate (control) were all treatments). The research was design to determine the interaction of coated seed and Burkina rock phosphate on the growth and yield of rice. However, treatment 1, 2, 3, 4, 5, 7 and 8 were the main plot whiles treatment 6, 9 and 10 were the sub-plots. The parameters measured included plant height, gravimetric soil moisture content, tiller count, effective tiller count, chlorophyll content, days to 50% flowering, plant height at harvest, straw biomass and grain yield.Findings: The outcome of the results obtained on treatment 1 shows significant on moisture content when coated seed of rice recorded highest among the treatments (Figure 02). Besides, similar results were obtained on plant height when coated seed of rice was compared with non-coated seed of rice on week after planting which confirmed significantly on 3, 6 (WAP) week after planting on Burkina rock phosphate and Triple superphosphate whiles non-coated seed of rice, Burkina rock phosphate and Triple superphosphate were significant on 6, 9 (WAP) week after planting (Figure 03 and Figure 04). Moreover, the results obtained gave similar outcomes when coated seed plus non-coated seeds of rice on treatment 1 and 4 were compared which shows significant on Burkina rock phosphate and Triple superphosphate on grain yield and straw weight (Figure 10 and Figure 11). However, among the treatment applied on tiller count phosphate (P2O5) was significant whiles Burkina rock phosphate and Triple superphosphate were significant on effective tiller count with coated seed plus non-coated seed of rice (Figure 05 and Figure 06). Comparatively under Burkina rock phosphate, coated seed of rice was significant in chlorophyll content whiles coated seed of rice shows significant among treatments on chlorophyll content at harvest (Figure 07 and Figure 08). Overall, results obtained on coated seed plus non-coated seed of rice on days to 50% flowering was significant on Burkina rock phosphate (BRP) and phosphate (P2O5) (Figure 09).Research Limitation: Deficiency of Burkina rock phosphate and Triple superphosphate resulted on the growth and yield.Originality/ Value: The experiment should further be repeated for confirmation of results on effect of coated seed and Burkina rock phosphate on the growth and yield of rice in the lowland ecology.
