The productivity of mustard (Brassica juncea L.) is significantly influenced by varietal potential and nutrient management practices, particularly under semi-arid conditions. A field experiment was conducted during Rabi 2024-25 at the Research Farm of Vivekananda Global University, Jaipur, to evaluate the effect of four mustard varieties (Varuna, Rohini, RH-725, and Giriraj) and four nutrient management levels (control, 50% NPS + 5 t/ha vermicompost, 75% NPS + 5 t/ha vermicompost, and 100% NPS + 5 t/ha vermicompost) on yield attributes, yield, and economics. The experiment was laid out in a factorial randomized block design (FRBD) with 16 treatment combinations replicated four times.
Results revealed that the variety Giriraj (V4) produced the highest number of siliquae per plant (155.75), seeds per siliqua (17.24), test weight (4.57 g), seed yield (1990 kg/ha), and net returns (Rs. 74,367/ha). Similarly, nutrient management with 100% NPS + 5 t/ha vermicompost (NM3) recorded maximum siliquae per plant (160.50), seed yield (2054 kg/ha), biological yield (6296 kg/ha), and net returns (Rs. 75,531/ha). The interaction effects were non-significant but indicated a synergistic trend. It can be concluded that Giriraj variety combined with 100% NPS + 5 t/ha vermicompost significantly improved yield and profitability of mustard under semi-arid conditions of Rajasthan. The findings highlight the importance of integrating varietal selection and nutrient management strategies to achieve higher productivity and sustainability.
