The interaction effect of sulphur and zinc on yield of linseed crop

Abstract

The present experiment was conducted at Rajoula agriculture farm of Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna (M.P.) during Rabi 2017-18. The soil of experiment field was sandy loam having 0.32% organic carbon, 10.55 kg/ha DTPA sulphur and 0.31 ppm available sulphur. The treatment comprised 9 combinations of 3 sulphur levels (0%, 0.5% and 1%kg S/ha) and 3 levels of Zinc (0, 5 and 7.5 kg Zn/ha). Sulphur was applied through w.p. All 9 treatment combination was tested in a factorial Randomized block design with 3 replications. The N, P and K fertilizers applied uniformly @ 30kg N + 15kg K2O/ha as urea, DAP and MOP respectively. Crop variety ‘Shekhar’ was shown on 07.10.2017 and harvested on 03.04.2018. Crop in its life period received no winter rain as winter season was totally dry. It is observed that the effect of sulphur was found significant on growth and yield of linseed where seed yield responded up to 0.5% kg/ha sulphur application. Zinc application has significant effect on growth and linseed yield. However, 7.5 kg /ha Zinc produced numerically higher seed yield over no application of Zinc. Interaction effect of S × Zn was significant on any crop character. However, the combined application of 0.5% kg S/ha plus 7.5 kg Zn/ha proved to be better than from crop production point of view.
