Field trial shows that lime, sulphur, and boron enhance rapeseed growth and yield, suggesting effective nutrient management strategies.
A field trial was conducted in Manipur, India during rabi season of 2020-2021 to find out the effects of lime, sulphur, and boron on rapeseed. Using a randomised block design, nine treatments were combined and replicated thrice: control, rdf, lime, sulphur, boron, lime + sulphur, lime + boron, sulphur + boron, and lime + sulphur + boron. The results revealed that combined application lime, sulphur and boron recorded highest growth attributes, yield attributes and nutrient content compared to rest of other treatments. Significantly, this treatment gave highest plant height (160.47 cm), number of branches plant -1 (15.67), number of siliqua plant-1 (142), seed yield (1,315 kg ha-1), oil content (35.83%) at harvest and observed considerably increase in NPK, Ca, S, and B content in seed and stover. As a result, the application of lime, sulphur, and boron could be employed to improve rapeseed growth and yield in acidic soil conditions.
