The experiment was carried out at Experimental field, Department of Horticulture, Sam Higginbottom Institute of Agriculture Technology and Sciences [formerly known as Allahabad Agriculture Institute Deemed University, AAI-DU] during the Spring season 2014-2015. The experiment consists of Thirteen treatments viz., (T₀) Control-RDF (100:120:100 N P K  kg ha^-1,), (T₁) 75% RDF + AZ@ 2.5 kg ha^-1,, (T₂) 75% RDF + FYM @ 10 ton ha^-1, (T₃) 75% RDF + VC@ 10 ton ha^-1, (T₄) 75% RDF + AZ @ 2.5 kg/ha +FYM @ 10 ton ha^-1+VC @ 10 ton ha^-1, (T₅) 50% RDF +AZ@ 2.5 kg ha^-1, (T₆) 50% RDF + FYM@ 10 ton ha^-1, (T₇) 50% RDF + VC@ 10 ton ha^-1, (T₈) 50% RDF +  AZ @ 2.5 kg ha^-1+FYM @ 10 ton ha^-1+VC @ 10 ton ha^-1, (T₉) 25% RDF + AZ@ 2.5 kg ha^-1, (T₁₀) 25% RDF + FYM@ 10 ton ha^-1, (T₁₁) 25% RDF + VC@ 10 ton ha^-1+, (T₁₂) 25% RDF +  AZ @ 2.5 kg ha^-1+FYM @ 10 ton ha^-1+VC @ 10 ton ha^-1. The treatments were replicated thrice in a Randomized Complete Block Design. The results revealed that Plants treated with 75% RDF + AZ @ 2.5 kg/ha +FYM @ 10 t/ha +VC @ 10 t/ha (T₄) significantly recorded maximum vegetative and Tuber yield attributes like plant height (91.87 cm), plant spread (92.38 cm), Number of Branches per plant (7.27), number of leaves per plant (26.53), number of tubers per plant (4.80), maximum tuber weight (958.53) and Maximum tuber yield per plant was recorded in T₄ (75% RDF + AZ @ 2.5 kg/ha +FYM @ 10 t/ha +VC @ 10 t/ha) (43.33g) followed by T₃ (75% RDF + VC @ 10 t/ha) (40.95g).
