An experiment was conducted to study the effect of tillage practices and different nutrient sources on growth, growth indices and yield of mustard. The experiment was directed in split plot design comprising of three main plots [(Zero tillage, Reduced tillage and conventional tillage) and four sub plots (75% RDN, 100% RDN, 75% RDF and 100% RDF) treatments]. Results revealed that plant height (137.92 cm), dry matter accumulation 2 2 (393.03 g/m), absolute growth rate (0.20 g/day), crop growth rate (0.83 g/m/day), dry matter efficiency (0.149%), 2 unit area efficiency (0.00062 kg/m/day), seed yield (1045.0 kg/ha) and straw yield (3242.3 kg/ha) of mustard were highest under reduced tillage. Among different nutrient sources, 100 per cent recommended 2 dose of fertilizer recorded highest plant height (139.72 cm), dry matter accumulation (407.81 g/m), dry matter 2 efficiency (0.151%), unit area efficiency (0.00065 kg/m/day), seed yield (1098.4 kg/ha) and straw yield (3112.6 2 kg/ha) whereas absolute growth rate (0.17 g/day) and crop growth rate (0.77 g/m/day) were highest with 75 per cent recommended dose of fertilizer. Correlation studies showed that plant height, dry matter accumulation, absolute growth rate, dry matter efficiency and unit area efficiency had positive significant association with mustard yield, indicating the importance of these traits in selection for yield. It was concluded that among tillage practices, reduced tillage proved best for growth and productivity of mustard whereas in case of different nutrient sources, 100 per cent recommended dose of fertilizerwas found better.
