Impact of different bio-fertilizers, seaweed extract and nutrients on the production of oilseed crops: A review

Abstract

Oilseed crops are a diverse group of plants that include sunflower, canola, soybean, and rapeseed. They supply essential fatty acids and are a good source of essential carbohydrates, and vitamins A, D, E, and K. The oil cakes and oil meals are excellent sources of protein (40-60%) for both humans and animals. Oilseeds are integral to global agriculture due to their multifaceted utility in providing edible oils, biofuels, and industrial raw materials. Achieving sustainability in the production of oilseed crops is crucial as agricultural systems face challenges from climate change, degraded soil, and limited resources. The objective of this review is to compile the most recent findings regarding the development, yield, and quality of oilseed crops through the use of various bio-fertilizers, seaweed extracts, and nutrient management techniques. Through a thorough examination of the literature, this review explores the roles of nitrogen-fixing bacteria and phosphate-solubilizing bacteria in improving soil fertility and nutrient availability to oilseed crops. Additionally, it investigates the potential of seaweed extracts to stimulate plant growth, improve stress tolerance, and raise yield by activating defense mechanisms and regulating hormones. The results highlight the potential for boosting oilseed crop productivity through the integration of bio-fertilizers, seaweed extracts, and nutrient management techniques as sustainable substitutes to conventional chemical inputs. It demands further research and planning to create specialized agronomic techniques for enhancing the sustainability and resilience of oilseed crop production systems worldwide.
