Abstract

An experiment was conducted during the winter (rabi) seasons of 2019–20 and 2020–21 at Sri Karan Narendra College of Agriculture (Sri Karan Narendra Agriculture University, Jobner, Jaipur, Rajasthan), Jobner, Jaipur, Rajasthan to evaluate the combined effects of organics and micronutrients on sprouting broccoli [Brassica oleracea (L.) Planck var. italica)]. Along with five organic treatments (Control, 10% Cow urine, 5% Panchagavya, 10% Vermiwash and Azotobacter), the treatment plan also included five micronutrient applications (Control, 15 kg/ha of Borax, 25 kg/ha of Zinc sulphate, 1.5 kg/ha of Ammonium molybdate and 10 kg/ha of Manganese sulphate). Primary curd weight (409.24 g), primary curd volume (237.71 cc), diameter of primary curd (23.05 cm), number of secondary curds (12.50), ascorbic acid content (108.96 mg/100g), secondary curd weight (258.93 g), total curd yield/plant (668.17 g), yield/plot (16.04 kg), yield/ha (329.96 q), and biological yield/hectare (1743 q) were all shown to be significantly improved by the combination of zinc sulphate applied to the soil and panchagavya applied topically. Furthermore, the benefit-cost ratio (4.05) and net returns (₹ 2,64,573/ha) were highest for this combination of treatments. To improve the production, quality, and financial returns of sprouting broccoli in this area, the best treatment is to apply 25 kg/ha of zinc sulfate to the soil and then spray 5% panchagavya on the leaves.
