Abstract

The field experiment was conducted at Horticulture Farm, S.K.N. College of Agriculture, Jobner (Jaipur) during Rabi seasons of 2016-17 and 2017-18. The experiment consisted of thirty five treatment combinations including seven INM (100 per cent RDF through inorganic fertilizer, 75 per cent RDF through inorganic fertilizer + 25 per cent through FYM (5 t/ha), 50 per cent RDF through inorganic fertilizer + 50 per cent through FYM, 100 per cent RDF through FYM, 75 per cent RDF through inorganic fertilizer + 25 per cent through VC, 50 per cent RDF through inorganic fertilizer + 50 per cent through VC and 100 per cent RDF through vermicompost and five bio-regulator levels [Control, Brassinoids @ 5 ppm, Brassinoids @ 10 ppm, Salicylic acid @ 100 ppm and Salicylic acid @ 150 ppm] were under taken in Split plot design with three replications. The results showed that the maximum weight of primary curd (222.51 g),  number of secondary curds per plant (6.58), weight of secondary curd (154.05 g), yield per plant (384.56 g), yield per plot (7.69 kg), yield per ha (189.90 q), biological yield per ha (1081.85 q) and net returns ( 304019/ha) were recorded with the application of 50 per cent RDF through inorganic fertilizer and 3.5 t/ha vermicompost (F5) in sprouting broccoli. Whereas, the maximum B:C ratio (4.39:1) was recorded under 75 per cent RDF supplied through inorganic fertilizer and 1.75 t/ha vermicompost. Harvesting index was found non significant. In the case of bio-regulators maximum weight of primary curd (213.17 g), number of secondary curds per plant (6.20), weight of secondary curd (147 g), yield per plant (362.57 g),  yield per plot (7.42 kg), yield per ha (183.19 q), biological yield per ha (1002.18 q), net returns ( 287563 / ha) and B:C ratio (3.99:1) were recorded significant by superior over control with foliar application of 5 ppm brassinoids. While harvesting index was found non significant to broccoli.
