A trial having 25 treatments was conducted in Factorial Randomized Blocks Design (F-RBD) with 3 replications. The treatments grouped into categories consisting 5 micronutrients (control, borax @15 kg/ha, Znso 4 @25 kg/ha, (NH 4 ) 2 MoO @1.5 kg/ha and Mnso 4 @10 kg/ha) and another category consisted 5 organics (control, cowurine @10%, panchagavya @5%, vermiwash @10% and azotobacter). The results indicated that soil application of Znso 4 as well as foliar application of 5% panchagavya to the sprouting broccoli signifcantly increased most of the plant attributes i.e. plant hight (71.88 cm and 71.95 cm), no. of leaves/plant (31.38 and 31.12), leaf area (3055 cm 2 and 3068 cm 2 ), chl-a (2.90 mg/g and 3.09 mg/g), total curd yield per ha (28.81 Mt/ha and 29.41 Mt/ha), NR (224848 `/ha and 230256 `/ha) and BCR (3.55 and 3.60), respectively in comparison to the control. Application of ZnSO 4 and panchagavya contributed 24.72 and 26.49%, respectively more in total curd yield per hectare as compared to control. Thus, fndings of experiment were in conclusion that application of ZnSO 4 @25 kg/ha in soil and application of panchagavya @5% as foliar spray have the prospective efect to enhance all attributes in sprouting broccoli not only in comparison to control but also to rest of other treatments. Keywords: Azotobacter, Cow urine, Growth, Micronutrients, Panchagavya, Vermiwash Broccoli (Brassica oleracea L. var. italic Plenck 2n=2x=18), belonging to the Brassicaceae family, is an important exotic vegetable and potential cole crop. It is an edible plant in the cabbage family that contains a group of immature green buds along with a stout, feshy fower stalk that forms a head. This head is consumed as a vegetable. The curd is full with most of vitamins and minerals, and having beta-carotene, a precursor of vitamin A about 14 times higher than cabbage and caulifower. It also contains the highest amount of protein among the cole crop. The curd also contains anti-cancerous and antioxidants compounds. As per composition its curd contains 5.5% carbohydrates, 3.3% protein, 137 mg vitamin-A, 0.05% vitamin- B 1 , 0.12% vitamin-B 2 , 0.80 mg calcium and 0.79 mg phosphorus (Thamburaj and Singh 2001). The cultivation of sprouting broccoli depends mainly on organic fertilizers such as farmyard manure and vermicompost, which contain little or no micronutrients and are slow to mineralize, leaving farmers unable to achieve the desired yield and return on investment. Nowadays, foliar application of certain organic products, viz. cowurine, panchagavya and vermiwash, as well as the application of specifc micronutrients (B, Zn, Mo and Mn) into the soil are cheaper, more environmentally friendly and stimulate plant growth, which increases the biological efciency of crops compared to normal complete organic fertilizer (Choudhary et al. 2017). Even though micronutrients are only needed in small amounts, they are essential for healthy plant growth and proftable crop production. In addition, micronutrients are actively involved in the plant metabolic process, such as cell wall development, respiration, photosynthesis, chlorophyll, enzymes and nitrogen fxation, as they act as co-enzymes. Among micronutrients, zinc is good for the formation of chlorophyll, various enzymes and growth hormones such as auxin. However, it can defcient in alkaline and sandy soils. Crops grown with organic and various micronutrients are nutritionally and environmentally superior. In view of these facts, the present experiment was designed to study the efects of micronutrients and organic matter on growth, yield and economics of sprouting broccoli.
