Abstract: The present investigation entitled “Effect of seed priming and plant spacing on the growth, productivity and soil health of spring groundnut (Arachis hypogaea L.)” was carried out at Students’ Research Farm, Department of Agronomy, PAU, Ludhiana, for two years during spring season of 2018 and 2019. Three plant spacings comprises 22.5 cm × 20 cm (G1), 30 cm × 15 cm (G2) and 45 cm × 10 cm (G3) allocated in main plot and six seed priming treatments viz. consortium bio-fertilizer (T1), cow urine (T2), vermicompost (T3), vermiwash (T4), combination of above materials (T5) and control (T6) were in sub plot of split-plot design (SPD) with four replications by using spring groundnut variety TG 37A. The results showed that all the growth parameters were significantly influenced by seed priming (except days to 50% flowering), but not by plant spacing. The significantly higher yield attributes were recorded in 22.5 cm × 20 cm (G1) plant spacing and in control (T6) among seed priming (except 100 kernel weight). The significantly higher pod yield, haulm yield and biological yield (q ha-1) were recorded in G1 plant spacing with consortium bio-fertilizer (T1) seed primed crop. The oil and protein content of spring groundnut kernels, soil enzyme activity (Dehydrogenase & Alkaline phosphatase) and soil available N, P and K (kg ha-1) were influenced non-significantly by both seed priming and plant spacing, but the haulm and kernel N, P and K uptake (kg ha-1) were significantly influenced (except haulm P). The gross & net returns (` ha-1) and B: C ratio were significantly higher under G1 plant spacing with seed priming of consortium bio-fertilizer (T1) and all the interactional effects regarding above parameters were found to be non-significant (except crop emergence).
