Abstract: A field experiment was conducted to study the effect of sowing dates and fertilizer levels on productivity and nutrient uptake of soybean-wheat cropping system. The productivity of soybean was higher sowing in meteorological week 24 and application of 100 per cent RDF to wheat crop (29.02, 29.80 and 29.41 q ha-1 and 38.30, 38.92 and 38.61 q ha-1) during both the years and pooled mean, respectively and it was at par with meteorological week 25 and application of 75 % RDF. Among the different sowing date treatments to soybean and 100 % RDF treatment to wheat crop recorded. The highest nutrient uptake in soybean and wheat (95.81, 96.04, 17.66, 17.69, 78.88, 80.82 and 100.54, 102.13, 21.45, 22.59, 117.10, 116.54 kg ha-1, respectively) were recorded by sowing in meteorological week 24 to soybean and 100 % RDF to wheat crop. Sowing in meteorological week 24 and 100 % RDF to wheat crop resulted in higher available NPK after soybean (187.67, 189.91, 17.16, 17.64, 201.46 and 205.97 kg ha-1) after soybean and wheat harvest (161.62, 162.86, 16.52, 17.88, 277.55 and 280.45 kg ha-1) respectively. The result of experiment revealed that sowing in meteorological week 24 to soybean and 100 % RDF to wheat found higher productivity and uptake of nutrients of soybean-wheat cropping system.
