Linseed (Linumusitatissimum L.) has been a traditional crop and it is the most important oil seed crop in production in the higher altitudes of Ethiopia. The needs for applying fertilizers are becoming obvious, as soil fertility has declined from time to time. Excessive use of fertilizers also affects farmers' economy, as the crop is relatively low yielder. In order to study the effect of nitrogen and sulphur on nitrogen and sulphur uptake of the crop, field experiment was conducted in factorial based randomized complete bock design with three replications at Sinana during the main cropping season of 2013. Treatments consist of four levels of nitrogen (0, 23, 46 and 69 kg N ha ). The results indicated that increased nitrogen application combined with sulphur increased seed nitrogen uptake as compared with the control plot (no nitrogen and sulphur). However, increasing sulphur application combined with nitrogen at 69 kg ha -1 progressively increased seed nitrogen uptake, but it showed a declining trend combined with the rest of nitrogen levels. Seed sulphur uptake was enhanced by the application of sulphur and it was higher at higher levels of both sulphur and nitrogen. However, to come up with a conclusive recommendation, the experiment should be repeated over seasons and locations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
