Effect of Nitrogen and Sulphur on Growth and Yield Attributes of Potato (Solanum tuberosum L.)

This investigation was carried out to study the effect of four levels of nitrogen (0,90,180,270) and three levels of sulphur (0,25,50) application on growth and yield attributes of potation a split plot design with three replication, at lovely professional university, Phagwara, Punjab, India. The treatments ware replicated thrice in split plot design. The study revealed that application of N 180 kgha-1 + S 50 kgha-1 significantly enhanced morphological and quality attributes such as plant emergence, number of shoots, periodic plant height, dry matter accumulation, leaf area index, percent reducing sugar and tuber dry matter, there by proving the role of sulphur and nitrogen in high tuber yield in potato ‘Kufri-chipsona-3’. Among all treatments,highest total and processable yield was exhibited by treatment T9 i.e N 180 kgha-1+S 50 kg/ha-1expressing the role of S in N uptake and use efficiency. Benefit cost (B: C) ratio was 2.25 which also indicates maximum profitability obtained with this combination.
