Growth attributes of intercrops
Plant height, biomass yield, straw yield and crop duration of first intercrops
differed significantly among the different treatment combinations except 1000-grain
weight. The highest plant height of 86.50 cm and 89.10 cm were found with the treatment
T 7 (PRC + 20 cm row spacing of onion seed crop - BINA Mung 5) while the lowest plant
height of 42.33 cm and 48.00 cm were recorded with T 2 (PRC + onion - BINA Mung 5)

onion seed crop - BINA Mung 5) and the lowest 1000-grain weight of 3.27 g and 3.3 g
were observed in T 7 (PRC + 20 cm row spacing of onion seed crop - BINA Mung 5)
treatment in both the years. The crop duration was lowest of 94 days and 100 days with
treatment T 2 (PRC + onion - BINA Mung 5) and the highest duration of 140 days and 141
days were found with T 4 (PRC + 40 cm row spacing of onion seed crop - BINA Mung

row spacing of onion seed crop - BINA Mung 5) and T 7 (PRC + 20 cm row spacing of
onion seed crop - BINA Mung 5) treatment in both the years (Table 3).
