Field experiment was conducted during Rabi, 2019 to study the “Effect of macronutrients, bio- fertilizers and micronutrients on yield and yield attributing characters of broccoli (Brassica oleracea var. italica L.)” with the sole purpose of studying the effect of inorganic fertilizers, bio-fertilizers and micronutrients on yield of broccoli and to find out the most appropriate combinations of the inputs for broccoli crop required under Bhubaneswar agroclimatic condition. The experiment was conducted at Instructional Farm – II, Agricultural Research Station Binjhagiri, Chatabar, Siksha “O” Anusandhan Deemed to be University, Bhubaneswar. The test crop broccoli (var.Shishir) received 10 different treatments namely; absolute control (T₁), N 100% + PK full (RDF)+ bio-fertilizers (T₂), N 75% + PK Full (RDF) +bio-fertilizers (T₃), N 50%+ PK Full (RDF)+ bio-fertilizers (T₄), N 100% + PK Full (RDF)+ micronutrients (T₅), N 75% + PK Full (RDF)+ micronutrients (T₆), N 50% + PK Full (RDF) + micronutrients (T₇), N 100% + PK Full (RDF) + bio-fertilizers + micronutrients (T₈), N 75% + PK Full (RDF) + bio-fertilizers + micronutrients (T₉) and N 50% + PK Full (RDF) + bio-fertilizers + micronutrients (T₁₀). Each treatment was replicated three times and imposed over a statistically laid out field in randomized block design. The 100% soil test based recommended dose of fertilizer for broccoli was (150:60:100) kg N P K/ha. Shisir variety of broccoli was transplanted at a spacing of (60×50) cm Application of different levels of N, P, K in combination with micronutrients and bio-fertilizers increase the curd yield per plot and thereby increasing the yield per hectare. The results revealed that the treatment T₈ (N 100% + PK Full (RDF) + bio-fertilizers + micronutrients) recorded maximum values for curd length(14.11cm), curd diameter (25.27cm), curd circumference (46.37cm),  curd yield plot^-1 (13.95 kg) and curd yield q ha^-1 (118.01 q^-1) which was followed by the treatment T₅ (N 100% + PK Full (RDF)+ micronutrients) and T₂ (N 100% + PK full (RDF)+ bio-fertilizer) respectively. From the present investigation it may be concluded that soil test based recommended dose of fertilizer (100%) combined with biofertilizers and micronutrients was the best treatment for getting higher yield from broccoli.
