Abstract
Purpose: Produced tubers with inferior quality are the main bottleneck for
exporting surplus amount of potato to the importing countries. Applying nitrogen
as prilled and super granule urea along with biochar may improve the yield and
processing quality of potato. To generalize a partial solution, the study was
conducted to find out the efficiencies of N forms and biochar towards the
improvement of the processing quality of potato for export.
Research Method: The experiment comprised two factors. Factor A: Nitrogen
fonn (2): Prilled Urea (Up) and Urea Super Granule (US), and Factor B: Biochar
level (6): BO-Control, 81- 2 tlha, B2- 4 tlha, B3- 6 t/ha, B4-8 tlha, and 85- 10
t/ha. The experiment was laid out in a split-plot design with three replications.
Results: Nitrogen form andlor biochar levels had shown significant influence on
most of then parameters. The maximum tuber yield of potato (37.9 t ha-l) was
observed from UsB5 which was statistically similar to UsB4. The maximum dry
matter content of tuber (21.8 %) and specific gravity of potato (1.098 g/cc) were
observed from UsB4. So, it may be concluded that the application of urea super
granule (US) plus biochar B4 (8 t/ha) was found best combination for maintaining
optimum yield and better processing quality of potato.
Findings: Application of biochar improved the soil organic carbon status (data not
shown) and exhibited better potato yield and qualities. Urea super granules (USG)
are much economic and environmental friendly
