Integrated use of organic and inorganic fertilizers can improve crop productivity and sustain soil health and fertility. The present research was conducted at Rallakothur village, Ambur taluk of Thirupathur district, during Karthigaipattam (Nov 2022-Mar 2023) to study the effect of integrated nutrient management on yield attributes and yield of groundnut. The results of the experiment revealed that application of N & K2O + Enriched poultry manure @ 750 kg ha-1 + ZnSO4 @ 15 kg ha-1 + Borax @ 10 kg ha-1 (Basal application) + Humic acid @ 2% on 25 and 45 DAS(T6) shown its supremacy by registering better yield attributes viz., number of pods plant-1 (20.83), shelling percentage (70.49), 100 kernel weight (37.52) and yield viz., pod yield (2165 kg ha-1) and haulm yield (3259 kg ha-1). This treatment is on par with application of N & K2O + Enriched poultry manure @ 750 kg ha-1 + ZnSO4 @ 15 kg ha-1 + Borax @ 10 kg ha-1 (Basal application) +Seaweed extract @ 5% on 25 and 45 DAS (T9).
