Indian mustard [Brassica juncea (L.) Czern & Coss] is one of the most important oilseed crops worldwide yet drought and salinity stress significantly reduced its growth and yield. The research was carried out in order to test the effect of salinity on osmoprotectants (total soluble sugars, proline), antioxidant molecules (ascorbate, α-tocopherol) and ionic content from the dry sample of the leaves in introgression lines and varieties of Brassica juncea. Permanent saline plots are maintained in the field of soil sciences where different doses of sodium carbonate were given to maintain the relative sodium bicarbonate (RSC) to three levels. The results revealed the significant effect of salinity on biochemical attributes as well as on ionic content. Increase in total soluble sugars, proline, ascorbate, α-tocopherol and Na+ ion whereas rest of the ions Ca2+, Mg2+ and K+ decreased with increased salinity levels. Increased accumulation of Na+ increased the Na+/K+ ratio and decreased the K+/Na+. Significant finding among the introgression lines and varieties revealed low Na+ and high K+ correspondingly Na+/K+ low and K+/Na+ ratio. Decreased calcium and magnesium ion resulted in decline in chlorophyll content and membrane stability under saline conditions while decreased K+ concentration regulated the opening and closing of stomata thus hampering photosynthesis.

A field experiment was conducted during the winter (rabi) season of 2013-14 and 2014-15 at research farm Hisar, Haryana in a split plot design having four dates (Oct 15 and 25, Nov 5 and 15) in main plots and five nitrogen levels (0, 40, 60, 80 and 100 kg N/ha) in sub plots with three replications to study the effect of sowing dates and nitrogen levels on growth and yield of Indian mustard. Results revealed that October 15 sown crop resulted in significantly higher total plant biomass and its partitioning at different growth stages, yield attributes, yields and oil content. Delaying the sowing dates from October 15 to November 15 reduced seed yield by 39.3 percent. Among the nitrogen levels, application of 100 kg N/ha led to record higher total biomass and its partitioning at all growth stages and resulted in higher yield attributes and seed yield. Oil content decreased with increased levels of nitrogen.
