Influence of INM on Yield, Quality of Potato and Soil Status

An experiment was carried out to study the Influence of INM on yield, quality of potato and soil status at Horticulture Research Farm, College of Horticulture, AAU, Anand during the three consecutive years 2020-21, 2021-22 and 2022-23. The experiment was laid out in Randomized Block Design with three replications and ten treatments viz., T1: 100 % RDF (220:110:220), T2: 20 t FYM + 100 % RDF (220:110:220), T3: 75 % RDF + 25 % RDN through FYM, T4: 75 % RDF + 25 % RDN through VC, T5: 50 % RDF + 50 % RDN through FYM, T6: 50 % RDF + 50 % RDN through VC, T7: 50 % RDF + 50 % RDN through FYM + 1 L Bio NPK consortium/ha, T8: 50 % RDF + 50 % RDN through VC + 1 L Bio NPK consortium/ha, T9: 25 % RDF + 50 % RDN through FYM + 1 L Bio NPK consortium/ha + KMB 1 L/ha, T10: 25 % RDF + 50 % RDN through VC + 1 L Bio NPK consortium + KMB 1 L/ha. The treatment T2 [20 t FYM + 100 % RDF (220:110:220] recorded maximum tuber weight per plant (487.13 g), tuber yield (434.8 q/ha) and grade “A” tuber (378.9 q/ha) in pooled analysis. Treatments T7 to T10 received inoculation of Bio NPK consortium showed higher microbial population. Whereas, grade “B” tuber, TSS and soil status after harvest were found non-significant in pooled data.
