India is one of the world's largest vegetable oil economies- currently accounting for roughly 13% of the world's oilseeds area, 7% of the world's oilseeds output, and 10% of the world's edible oil consumption. For oilseeds, apart from major plant nutrients like nitrogen, phosphorus and potassium, sulphur and boron plays an vital role in the production phenology. Soil samples examined across the country were insufficient in accessible sulphur and boron deficiency holds at about 50 percent. When both elements were applied in conjugation the total enhancement exceeded the additive effect (independently by both nutrients) by the virtue of the synergistic effect shown by sulphur and boron thereby increasing yield attributes of oilseeds viz. seed yield, dry matter, number of seeds, seed oil quality and quantity and protein content of seed. Research shows application of sulphur at a rate of 30-40 kg ha-1 and boron at 2.5-3 kg ha-1 proved to be most beneficial for oilseeds like rapeseed and sunflower. Interaction between boron and sulphur also led to increased availability and uptake of other primary and secondary nutrients by the plants. The synergistic impact aided post harvest soil of oilseed crops counted as in increased nutrient content and organic carbon content without effecting the pH and EC also the higher nutritional content of food, such as increased oil and protein content, is another strategy to future food safety

Boron, Interaction, oilseed crops, Sulphur

It is clearly stated over the years that adding sulphur and boron beyond the recommended dose of NPK fertilizers in oilseed crops results in considerable increase in Seed yield, stover yield and increased content of protein and oil in the seeds- the increased protein content of the seeds results in a more nutrition rich crop for consumption. The post harvest soil is also benefited from the conjugative applications of boron and sulphur because of increased levels of Organic carbon, primary nutrients like nitrogen, phosphorus and potassium along with some secondary nutrients like sulphur and micronutrients like boron. The uptake of nutrients by the succeeding crop in also improved. As the cropping system intensifies due to increased demand for food in the coming years, the nutrient supplying capacity of the soils gets destroyed therefore, it becomes essential to improve the fertilizer use efficiency and utilizing the complimentary and synergistic effects of the nutrients on a wide scale
