Abstract:
Rapeseed and mustard is most important group of oilseed crops grown under the wide range of agro-climatic conditions in India. These crops are economically important for local and international market. The edible oil content in rapeseed and mustard crop, range from 30-48%. This also used as main cooking oil in northern India. All parameters viz., plant population, plant hight (cm), number of branches per plant, number of primary and secondary branches per plant, leaf area index, harvest index in mustard crop were recorded maximum with the application of the 100% RDF + 25 kg Sulphur ha^-1 + PSB (T₇) than other treatments. Similarly, the application of treatment T₇ resulted in to significantly increases dry matter accumulation per plant, biological yield and test weight in mustard crop than other treatments at all the stages. The treatments T₇ were recoded maximum number siliques per plant, maximum number of grains per silique, maximum length of silique than other treatments. The maximum stover yield, seed yield, oil content and oil yield of mustard crop were also recorded in treatment T₇ which was more than other treatments. The treatments T₇ (100% RDF + 25 kg Sulphur ha^-1 + PSB) resulted in to similar N, P and K content and uptake by seed mustard crop but significantly more than other treatments. The effect of PSB and sulphur on mustard was found beneficial with the application of 75% RDF + 25 kg Sulphur ha^-1 + PSB inoculation gave the maximum net return and benefit cost ratio.
