A field
experiment was conducted at Haramaya and Hirna to study the effect of
nitrogen and sulphur application on yield components and yield of common
bean during the 2012 main cropping season. The treatments consisted of
three nitrogen rates (0, 23, 46 kg N ha-1) and four sulphur rates (0,
20, 40 & 60 kg S ha-1). The experiment was laid out as a randomized
complete block design with three replications. The main effect of
nitrogen had a significant influence on days to flowering, days to
physiological maturity, plant height, leaf area index, number of pods
per plant aboveground dry biomass, grain yield and harvest index. The
main effect of sulphur had no significant effect on all of the
parameters except a number of effective nodules per plant at both
locations. Grain yield was significantly higher at Hirna than at
Haramaya. Significantly higher grain yield was obtained in response to
the application of 23 and 46 kg N ha-1 at Hirna, which resulted in the
production of grain yields of 6.5 and 6.7t ha-1, respectively. However,
at Haramaya, the highest grain yield(6.7t ha-1) was obtained in response
to the application of 23 kg N ha-1. Grain quality was not altered by
nitrogen and sulphur application, except the total phosphorus, which was
significantly affected by nitrogen application. In conclusion, the
results revealed that nitrogen at moderate rates led to significant
enhancements in yield components and grain yield. It could, thus, be
deduced that application of nitrogen markedly increases the productivity
of the crop in the region. How to cite this article: Tadesse N, Dechassa N (2017). Effect of Nitrogen and Sulphur Application on Yield Components and Yield of Common Bean (Phaseolus Vulgaris L.) in Eastern Ethiopia. Acad. Res. J. Agri. Sci. Res. 5(2): 77-89
