Abstract:
The present investigation entitled “Response of Indian mustard (Brassica Juncea L.) to sources and levels of sulphur on oil content and nutrient uptake.” was carried out during Rabi season of 2018 and 2019 at Agronomy Research Farm of the A.N.D. University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.). The 36 treatment combinations having three sulphur sources viz. Phosphogypsum, Elemental Sulphur and Single Super Phosphate were investigated with four levels of sulphur viz. 0.00 kg ha^-1, 20 kg ha^-1, 40 kg ha^-1 and 60 kg ha^-1 was kept in different plots. The experiment in F-RBD and replicated in three times. The total Nitrogen, Phosphorus, Potassium and Sulphur uptake by crop was highest recorded 106.55, 36.93, 150.63 and 20.93 kg ha^-1 respectively with phosphogypsum source of sulphur significantly as compared to rest two sources of sulphur in seed, stover and crop during both the years of experimentation. As far as doses of sulphur was concerned, Nitrogen, Phosphorus, Potassium and Sulphur uptake increased with simultaneous increase in S doses resulting maximum value at 60 kg Sulphur ha^-1(108.17, 37.50, 152.73 and 21.93 kg ha^-1 respectively) which exhibited significance over rest of sulphur doses. The trend of increase was similar in uptake by seed, stover and crop during both the years of study. The highest oil content 38.57% and 38.81% in seed was noted during first and second year respectively from phosphogypsum source of sulphur and level of sulphur is 60 kg Sulphur ha-1 which exhibited statistical similarity with rest sources of sulphur and level of sulphur.
