Effects of Secondary and Micro Nutrients on Rice (Oryza sativa L.) Growth, Development and Yield
Abstract
A replicated field trial was carried out at the research field of CSIR- Savanna Agricultural research Institute (CSIR-SARI) Nyankpala during the 2016 cropping season, to determine the integrated effects of macro (N,P,K), secondary (S and Mg) and micro nutrients (B, Zn and Cu) on rice growth, development and yield using omission trial. The experiment was laid out in a randomized complete block design. The results revealed that the maximum number of tillers per square meter, dry weight of biomass and paddy yield was obtained when all the nutrients (NPK, S, Mg, B, Zn and Cu) were used. Yield decreased with the omission of K, S, Mg, B, Zn and Cu. Sulphur exclusion promoted panicle development, but caused 20% paddy yield loss; could it be that some of the panicles were not productive. Further experiment should be conducted to ascertain why the omission of Sulphur promoted panicle development but decreased grain yield.
