Abstract:
An agronomic investigation entitled as “Effect of phosphorus and sulphur on growth yield and quality of Indian mustard (Brassica juncea L.) was conducted at Experimental Farm, Agronomy Section, College of Agriculture, Latur, during Rabi 2020-21. The objective of present study was to study the effect of phosphorus and sulphur levels on growth, yield and quality of mustard and to study the economics of mustard cultivation. The soil of experimental plot was clayey in texture, slightly alkaline in reaction, low in available nitrogen, medium in available phosphorous, very high in available potassium and low in available sulphur. The experiment was laid out in Factorial Randomized Block Design (FRBD) with nine treatment combinations, consisting of two factors i.e. different phosphorus levels and sulphur levels, which includes three levels each of different phosphorus levels and sulphur levels application. The different fertilizer levels were 25 kg P ha^-1 (P₁), 37.5 kg P ha^-1 (P₂) and 50 kg P ha^-1 (P₃) whereas, sulphur levels were 15 kg S ha^-1 (S₁), 30 kg S ha^-1 (S₂) and 45 kg S ha^-1 (S₃). The gross plot size of each experimental unit was 5.4 m × 4.5 mand net plot size was 4.5 m × 3.9 m. Sowing was done on 09^th November, 2020 by dibbling method at spacing 45 cm x 15 cm. The crop was harvested on 22^rd February, 2021. The result of the experiment revealed that higher seed yield (1897 kg ha^-1), oil yield (779.92 kg ha^-1), GMR (Rs.75880 ha^-1), NMR (Rs. 39549 ha^-1) and B:C ratio (2.09) was observed with an application of 50 kg P ha^-1 (P₃) Higher seed yield (1864 kg ha^-1), oil yield (718.27 kg ha^-1), GMR (Rs.74560 ha^-1), NMR (Rs.36640 ha^-1) and B:C ratio (1.97) was observed with an application of 45 kg S ha^-1 (S₃). In case of seed yield and net monetary returns (Rs. ha^-1), application of 50 kg P ha^-1 and 45 kg S ha^-1 performed better.
