ABSTRACT

Oilseed cakes that are left after oil extraction are chiefly used as an organic soil amendment, plant conditioner, and cattle feed. These oilseed cakes are rich in protein, nitrogenous compounds, and minerals. Besides its conventional usage, studies have been conducted to utilize these nutrient-rich resources for soil conditioners. Considering the exponentially increasing human population and escalating food demand, these chemical-rich sources can be novel options to enrich the crop’s yield by reducing the disease severity caused by plant pathogens, including nematodes. Using the oilseed cakes with an integrated approach remarkably enhances plant growth and reduces harmful pathogens in rhizospheric regions. The reduction in disease severity is due to bioactive compounds in oilseed cake. Therefore, existing bioactive compounds that act as antagonists for nematodes and other plant pathogens would be used as an alternative to chemical pesticides. This chapter focuses on analysing the role of oilseed cake as an eco-friendly organic source, characterization, extraction techniques, and utilization in agriculture.
