Growth and Yield of Maize (Zea mays L.) as Influenced by Planting Geometry and Nutrient Management in Maize Based Intercropping

摘要

Afield experiment was conducted at Zonal Agricultural Research Station, University of Agricultural Sciences, GKVK Bangalore during kharif- 2016 to develop suitable planting geometry and nutrient management practices for maize based intercropping system. The results revealed that between the planting geometry, paired row planting of maize (30/90x30 cm) has recorded significantly higher kernel yield (7286 kg ha~(-1)), stover yield (8748 kg ha~(-1)), maize equivalent yield (11039 kg ha~(-1)), LER (1.29)and ATER (1.14). Among the intercrops, kernel and stover yield were found to be non-significant. However, significantly higher maize equivalent yield (13309 kg ha~(-1)), LER (1.39) and ATER (1.20) were recorded in maize + french bean intercropping system. Among the nutrient management practices, base crop RDF + proportionate RDF for intercrops has recorded significantly higher kernel yield (7452 kg ha~(-1)), stover yield (8950 kg ha~(-1)), maize equivalent yield (11279 kg ha~(-1)), LER(1.33) and ATER (1.17).
