Now-a-days, conservation of soil health and environment is a major issue during neutrient management for crop plants as imbalance use of inorganic fertilizers caused gradual decline in productivity of crop plants in recent past. Integrated nutrient management (INM) is an approach which involves judicious combined use of chemical fertilizers, organic manures including crop residues, vermicompost, green manures and biofertlizers in specific farming system to attain particular yield targets in crop plants. Cultivation of bulbous flower crops like Lilium, Gladiolus, Tuberose, Tulips, Dahlia, etc. forms major source of income for the farmers due to high demand for their cut flowers and flower bulbs in domestic as well as export market. INM in bulbous crops needs due attention to get quality flowers, high yield, quality planting material and to manage macro and micronutrient disorders. The main agenda of INM in bulbous crops involves balanced application of appropriate fertilizers at right time using right method to achieve target yield. INM techniques like fertigation through drip irrigation, use of controlled release fertilizers and speciality fertilizers, vermicompost and biofertlizers are very helpful to conserve soil health and environment. Nutrient conservation in the soil can be done through organic mulches, cover crops, intercropping and biological nitrogen fixation which act as physical barriers to wind and water erosion. Nutrient recommendation for bulbous crops through soil and plant analysis is very essential to maintain soil health and productivity of flower crops. In this regard, new approaches like Site Specific Nutrient Management (SSNM), Soil Test Crop Response (STCR), 4R stewardship concept given by International Plant Nutrition Institute (IPNI's) would help in minimizing nutrient loss, increasing nutrient use efficiency, enhancing yield and promoting environmental sustainability.
