A critical review on Integrated Nutrient Management (INM) in sweet corn

Abstract

The continuous use of inorganic fertilizers increases the cost of production, deteriorates soil health and pollutes the environment. Optimum use of organic manures like FYM, vermicompost and bio fertilizer provides all essential nutrients to plant and improves physical, chemical and biological properties of soil. The approach on integrated nutrient management (INM) with judicious use of organic and inorganic nutrient is indispensable for intensification of research. INM helps in the balanced fertilization of crops, where the right amount of plant nutrient from an appropriate source is applied at proper growth stage of a specific crop plant. It is a step towards sustainable agriculture as it reduces the stress of pollution on the nature and the judicious use of resources optimises the productivity. The recent years research work carried out on the integrated nutrient management in India and abroad with respect to growth, yield, nutrient uptake, quality parameters and economics of sweet corn has been critically reviewed in this chapter.

Influence of Bio-fertilizers and Phosphorus on Yield and Economics of Toria (Brassica campestris L.)

“…INM is the most effective method for maximising available resources and producing crops at the lowest possible cost. Inorganic fertiliser price increases and soil degradation may also be addressed by the efficient and combined application of sufficient nutrients by inorganic and organic fertilisers [2]. Biofertilizers are wellknown to play a number of important roles in increasing soil fertility, crop productivity, and crop production in agriculture because they are ecofriendly, but they cannot replace chemical fertilizers because they are critical in achieving higher crop yields [3].…”

Response of Enriched Biochar and Vermicompost on Nutrient and Seed Quality by Sweet Corn

“…Integrated nutrient management (INM) for balanced fertilization is critical for achieving potential productivity, quality, and energy efficiency while also preserving soil health [3]. Vermicompost [4], poultry manure [5], and biochar [6] are examples of organic materials with potential uses for boosting nutrient content and seed quality. Biochar has the potential to improve animal waste composting operations by extending the thermophilic phase, lowering ammonia, methane, and nitrous oxide emissions, and decreasing the pH of compost material.…”
