Effect of different nutrient managements and weeding regimes on weed density at 30 and 60 days after seeding (DAS) in hybrid maize. RDF (recommended dose of fertilizer): 100% recommended dose (RD) of NPK through fertilizer, RDF + VC: 25% RDN through VC, RDF + FYM: 25% RDN through FYM, RDF + BSM: 25% RDN through BSM, RDF + NC: 25% RDN through NC, Weedy check: Un-weeded control, Chemical weed management: Atrazine 1000 g/ha at 2 DAS, Integrated weed management: Atrazine 1000 g ha−1 at 2 DAS followed by mechanical weeding at 30 DAS. Effects of nutrient source recorded at 30 DAS in year 1 indicated with the lower case of letter (a, b or ab) and indicated with upper case of letter (A, B or AB) in year 2; however data recorded at 60 DAS indicate as lower case with (′) (a’ or b’) in year 1 and upper case with (′) (A’, B’ or AB’) in year 2; while effect of weed management in year 1 as italic lower case (a, b or ab), in year 2, italic upper case (A, B or AB) at 30 DAS, as italic lower case with (′) (a’ or b’) in year 1 and italic upper case with (′) (A’, B’ or AB’) in year 2 at 60 DAS.
