Abstract

A field experiment was conducted during the winter (rabi) season of 2016-17 at Banaras Hindu University (Varanasi) in a split plot design having three nitrogen levels (90,120 and 150 kg N ha-1) and two genotypes (Pusa Bold and RH- 749) in main plots and three sulphur levels (0, 25 and 50 kg S ha-1) in sub plots with three replications to study the effect of nitrogen and sulphur levels on growth and nutrient uptake of Indian mustard (Brassica juncea L.) genotypes. Results revealed that application of 150 kg N and 50 kg S ha-1 improved all the growth attributing characters viz. plant height, primary and secondary branches and shoot dry weight, nutrient (N, P, K and S) content and uptake as compared to lower levels of nutrients applied. Application of 50 kg S ha-1 improved plant height, shoot dry weight, primary and secondary branches by 3.96%, 9.66%, 8.75% and 14.29%, respectively over the control. Among genotypes, ‘RH- 749’ showed distinct superiority with respect to growth parameters (plant height and shoot dry weight) and nutrient uptake over ‘Pusa Bold’. Combined application of 150 kg N and 25 kg S ha-1 to Indian mustard genotype ‘RH- 749’ was found more remunerative.
