Abstract: To study the soil test based fertilizer recommendation for mustard crop on grain and straw yield, nutrient uptake and soil test data were used for obtaining basic parameter viz., Nutrient requirement, contribution of nutrients from soil, fertilizer and organic manure. It was found that 5.22 kg N, 0.99 kg P2O5 and 4.25 kg K2O were required for producing one quintal of grain. The per cent contribution of soil nitrogen, phosphorus and potassium were 23.94, 70.45 and 22.14 the percent contribution from applied fertilizer were 42.53, 21.44 and 90.52 per cent of nitrogen, phosphorus and potassium respectively. The fertilizer adjustment equation were developed for mustard (var. Shivani) and quantitative estimation of fertilizer doses formulated for a range of soil test values and desired yield targets under NPK alone and with FYM.
