A field experiment was conducted during the rainy (Kharif) season of 2020 at CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, to study the effect of organic and inorganic sources of nutrients on productivity of soybean (Glycine max L). The experiment was laid out in randomized block design comprising of eight treatments [T1 - 75 per cent RDN (FYM), T2 -100 per cent RDN (FYM), T3 -75 per cent RDF (Fertilizers), T4 - 100 per cent RDF (Fertilizers), T5 - 50 per cent RDF (Fertilizers) + 25 per cent RDN (FYM), T6 - 50 per cent RDF 5 6 (Fertilizers) + 50 per cent RDN (FYM), T7 - 100 per cent RDN (FYM) + rest P and K (Fertilizers) and T8 - Control (N P K )]. The soil of the experimental site was silty clay loam in texture and acidic in reaction, low in 0 0 0 available nitrogen (N), medium in available phosphorus (P) and potassium (K). Significantly higher plant height and dry matter accumulation recorded in T6 at all growth stages which was at par with T7 and T4 . The shortest plants were recorded in control treatment. Significantly higher absolute growth rate was noted at 30 DAS in T6 while lowest was in control treatment. Significantly higher CGR was noted at 60 DAS in T6 which was at pat with T7 and T4 while significantly higher RGR value noted in T7 which was at par with T6 and T4 while both of CGR and RGR (Relative Growth Rate) remained non-significant at all other growth stages. The lowest values of CGR and RGR were noted in T8. The highest value of DME (0.93) was recorded in T5 while the lowest value was in control. The highest UAE (Unit Area Efficiency) was noted in T5 (1685 kg/ha) followed by T6 while the lowest was in control treatment. Application of 50 per cent recommended dose of nutrients from fertilizers and 50 per cent of recommended dose of nitrogen from farm yard manure proved to be the best treatment for better growth and growth indices.Keywords
