Effect of Boron and Sulphur Application on Plant Growth and Yield Attributes of Potato (Solanum tuberosum L.)

Abstract

The present investigation was carried out to study the effect of boron and sulphur application on plant morphology and yield of potato during the month of October in 2015-16 and 2016-17. The experiment was laid out in randomized block design with three replications and thirteen treatments. Out of thirteen treatments one control, one recommended dose of fertilizers (N/P/K: 150/80/120 kg ha-1) and eleven treatment combinations along with recommended dose of fertilizers (RDF) including 3 doses of boron (1 kg, 2 kg and 3 kg); 2 doses of sulphur (30 kg and 40 kg) and their combinations (1 kg boron + 30 kg sulphur, 2 kg boron + 30 kg sulphur, 3 kg boron + 30 kg sulphur, 1 kg boron + 40 kg sulphur, 2 kg boron + 40 kg sulphur and 3 kg boron + 40 kg sulphur) were applied. The study indicated that plant morphology and yield of potato plant were significantly influenced by boron and sulphur application. The maximum plant height and yield of marketable tubers (17.99 t ha-1 and 27.00 t ha-1) were recorded in the plants treated with RDF + 2 kg B + 40 kg S during both year of investigation. RDF + 2 kg B + 40 kg S was also found statistically at par with the maximum values under characters viz., number of sprouts per tuber, stem diameter and number of marketable tubers/hill.
