Integration of different sources of nutrients on growth and yield of potato (Solanum tuberosum L.) CV. Kufri Chipsona

Field experiment was conducted during rabi seasons of 2009–10 and 2010–11, to study the effect of application of different sources of nutrients on growth and yield of Potato (Solanum tuberosum L.). Thedifferent sources of organic and inorganic fertilizers were integrated into 6 possible treatments viz. T₁: 90 Kg N + 37 Kg P₂O₅ + 68 Kg K₂O + 75 Q NADEP/hac, T₂: 60 Kg N + 25 Kg P₂O₅ + 45 Kg K₂O + 100 Q NADEP/hac,, T₃: 30 Kg N + 12Kg P₂O₅+22 Kg K₂O +125 Q NADEP/hac, T₄: RDF (120 Kg N + 50 Kg P₂O₅+ 90 Kg K₂O) T₅: 200 Q NADEP/Ha and T₆: Control. All the treatments resulted in improvement ofgrowth and tuber yield characters in Potato, out of these treatments where organic sources of nutrientwere integrated registered significantly maximum effect. Highest growth and tuber yield in potato wererecorded in the treatment T₄: 30 Kg N + 12Kg P₂O₅+22 Kg K₂O +125 Q NADEP/hac, while the lowest wasobserved in control treatment where none of the fertilizer was applied by any source. Nutrient suppliedthrough integrated source are showed significant higher yield and growth in comparison to nutrientsupplied through chemical fertilizers alone.
