Performance of Indian mustard (Brassica juncea) under different intercroppingsystems in Central plain zone of Uttar Pradesh

The field experiment was carried out during winter (rabi) season of 2021–22 on Students’ Instructional Farm of C.S. Azad University of Agriculture & Technology, Kanpur to assess the performance of Indian mustard under in- tercropping systems with chickpea, linseed, lentil and pea. The experiment was laid out in Randomized Block De- sign with 9 treatment combinations replicated thrice. These treatments included Sole Mustard (T1 ), Mustard: Chickpea (T2 1:1 and T3 2:1), Mustard + Lentil (T4 1:1 and T5 2:1), Mustard + Linseed (T6 1:1 and T7 2:1), and Mus- tard + Field Pea (T8 1:1 and T9 2:1). The results revealed that yield attributes and yield of mustard was significantly higher in sole Mustard and Mustard + Lentil (1:1) intercropping system. The maximum number of branches/plant (37, 38.33 at 30 and 90 DAS, respectively), siliquae/plant (380), seeds/siliqua (16), test weight (4.89 g), seed yield (2.89 t/ha), stover yield (6.80 t/ha), biological yield (9.68 t/ha), and harvest index (29.80%) were recorded in T1 (sole Mustard). Among intercropping system T4 (Mustard + Lentil, 1:1) resulted the maximum number of branches/ plant (36.75, 38 at 30 and 90 DAS, respectively), siliquae/plant (375), seeds/siliquae (16), test weight (4.84 g), seed yield (2.53 t/ha), stover yield (5.90 t/ha), biological yield (8.43 t/ha), harvest index (30.03%) and mustard equivalent yield (2.77 t/ha).
