Abstract: A field experiment was conducted in two consecutive rabi 2016-17 and 2017-18, at Mainpat, Chhattisgarh to find out the suitable date of sowing, residual nutrient of preceding crop and direct effect of nutrient at varying levels on succeeding buckwheat for obtaining higher productivity, profitability nutrient uptake and quality of local buckwheat cultivars in hilly area of Chhattisgarh. The experiment was laid out in split-split plot design with three date of sowing viz., D1-1st week of October, D2- 3rd week of October and D3-1st week of November as main plot treatments and three residual nutrient effect of preceding crop viz., F1-100% RDF, F2-100% RDF + 5 t FYM ha-1 and F3-150% RDF as sub plot treatments and three direct application of nutrients viz., F0-Control, F1-50% RDF and F2-100% RDF on buckwheat, as sub-sub plot treatments. Results revealed that sowing of buckwheat on 1st week of October (D1), recorded significantly higher plant height (85.77, 86.28 cm), primary branches plant-1 (6.70, 6.80), dry matter accumulation plant-1 (7.07, 7.17 g), number of seeds plant-1 (171.19, 177.04), seed weight plant-1 (4.19, 4.25 g) and 1000 seed weight (22.53, 22.66 g), seed yield (9.41, 9.52 q ha-1), NPK uptake by grains, net return ( 24207, 25430 ha-1) and B:C ratio (2.80, 2.75). Higher protein content (13.07, 13.32%), but no significantly affected by the date of sowing. Among the residual nutrient of preceding crop with 150% RDF recorded significantly higher all growth characteristics, yield attributes, seed yield, NPK uptakes, protein content, net return and B:C ratio. Irrespective of direct application of nutrients with 100% RDF recorded significantly higher plant height plant height (80.33, 81.07 cm), primary branches plant-1 (6.73, 6.82), dry matter accumulation plant-1 (6.91, 7.00 g), number of seeds plant-1 (165.46, 170.06), seed weight plant-1 (4.29, 4.34 g) and 1000 seed weight (22.65, 22.69 g), seed yield (9.02, 9.08 q ha-1), NPK uptake by grains, protein content (13.16, 13.44%) and net return ( 21319, 22230 ha-1), except B:C ratio (2.52, 2.46), it was recorded under control (F1) treatment.
