Abstract
Integrated Nutrient Management (INM) is an eco-friendly and sustainable approach that integrates organic manures, inorganic fertilizers, and biofertilizers to improve nutrient use efficiency, crop productivity, farm income, and soil health. This review critically synthesizes research on the effects of INM on the growth, yield, quality, and economics of sprouting broccoli (Brassica oleracea var. italica). It examines the nutrient requirements and soil fertility constraints of broccoli production and evaluates the roles of organic amendments, mineral fertilizers at different application rates, and biofertilizers in synchronizing nutrient release with crop demand. The review also summarizes methodological approaches used to assess vegetative growth, root development, nutrient uptake, and yield attributes. Available studies consistently show that integrated nutrient management improves vegetative growth, marketable head yield, quality traits, and phytochemical content more effectively than the sole application of organic or inorganic nutrient sources. The review further discusses the influence of Agro-climatic variability, environmental implications for soil health and greenhouse gas emissions, and the potential of precision nutrient technologies. Finally, it identifies research gaps, including the need for long-term field trials and socioeconomic adoption studies, to refine INM strategies for sprouting broccoli cultivation and support sustainable production.
