A field experiment was conducted during Rabi season 2018-2019 to study the “Effect of organic and inorganic sources of nitrogen fertilizers on soil properties and yield of broccoli (Brassica oleracea var. italica)” at Students’ Research Farm, P.G. Department of Agriculture, Khalsa College, Amritsar. The experiment was laid out in randomised block design (RBD) replicated three times with ten treatments. Plant nutrients applied through inorganic fertilizer or in combinations with organic manures along with bio-fertilizer did not show any significant effect on pH and EC in different treatments but organic carbon content was influence significantly due to application of 100% FYM + bio-fertilizer compared to rest of treatments. The availability of macro and micronutrients were profound increased by integrated use of nutrient sources. Maximum values of available N, P and K were observed to be 243.10 kg ha-1, 21.24 kg ha-1 and 310.63 kg ha-1, respectively in a treatment where 50% nitrogen was supplied through inorganic fertilizer + 50% N through poultry manure conjoint with bio-fertilizer. Similarly, available micronutrients (Zn, Fe, Cu and Mn) were also found highest in treatment T10. During the experimentation, growth and yield attributes were also recorded. However, values regarding plant growth parameters, yield as well as nutrient uptake were noticed highest in treatment T2 (100% NPK through inorganic fertilizers) which was at par with T10 in which integrated nutrient system applied. The overall results suggests that integrated application of organic inputs along with 50% reduced chemical fertilizers was found to be best for sustaining crop productivity and enhance the soil health.
