Abstract
A field experiment was conducted at Tamil Nadu Agricultural University, Coimbatore during kharif 2013 to investigate the influence of intercropping systems and weed management practices on the growth and yield of maize under irrigated condition. The experiment was laid out in split plot design and replicated thrice. The popular maize hybrid CO6 was used as test variety. Three intercropping systems and four weed management practices were accommodated under main plot and subplots, respectively. The sole crop of maize recorded improved growth parameters, yield attributes and yield than maize under intercropping systems. The reduction in yield under maize + blackgram intercropping at 1:1 ratio was negligible (3.52 %), whereas there was a significant reduction in the grain yield of maize (7.57 %) under maize + blackgram intercropping at 2:2 ratio. The yield attributes viz., cob length, cob girth, number of grain rows cob-1, number of grains row-1, cob weight and test weight were higher under sole maize among intercropping systems and pendimethalin 0.75 kg ha-1 as PE 3 DAS + one HW 25 DAS among weed management practices. The treatment combination of sole maize with pendimethalin 0.75 kg ha-1 as PE + one HW 25 DAS (I1W2) recorded higher grain yield (5755 kg ha-1) followed by maize + blackgram intercropping at 1:1 ratio with pendimethalin 0.75 kg ha-1 as PE + one HW 25 DAS (I2 W2).
