摘要

To assess the impact of tembotrione on weed growth, yield and economics of maize (cv. KH 101), field trials were conducted during the kharif season of 2014 and 2015 on a silty clay loam soil at Palampur. Tembotrione 100,125 and 150g ha~(-1), each applied at 20 and 30 days after sowing (DAS) of maize, tembotrione 125 and 150 g ha~(-1) + surfactant applied on 20 DAS of maize, atrazine 1000 g ha~(-1) (pre) fb atrazine 750 g ha~(-1) (post) and atrazine 1000 g ha~(-1) + pendimethalin 1000 g ha~(-1) (pre) were compared to manual weeding (20,40 and 60 DAS) and weedy check. Application of tembotrione at 125 and 150 g ha~(-1) with surfactant (20 DAS) and at 150 g ha~(-1) without surfactant (30 DAS) effectively reduced the dry weight of Echinochloa colona, Commelina benghalensis, Polygonum alatum, Ageratum conyzoides and the combined of all weeds. Tembotrione 125 and 150 g ha~(-1) + surfactant (20 DAS) produced significantly higher grain yield of maize followed by tembotrione 150 g ha~(-1) applied on 30 DAS, tembotrione 125 g ha~(-1) applied on 30 DAS and tembotrione 150 g ha~(-1) applied on 20 DAS. Grain yield of maize negatively correlated with dry weight of Echinochloa, Commelina, Polygonum, Ageratum and the combined of all weeds. With every 1 g m~(-2) increase in weed dry weight, the grain yield of maize reduced by 33.7 kg ha~(-1). The economic threshold levels with the herbicidal management practices varied between 5.1-9.3 g m~(-2) and that with manual weeding 46-50.8 g m~(-2). Tembotrione 150 g ha~(-1) + surfactant and tembotrione 125 g ha~(-1) + surfactant applied on 20 DAS and tembotrione 150 g ha~(-1) applied on 30 DAS gave higher weed control efficiency, crop resistance index and efficiency index and lowest weed index over other treatments. Herbicidal treatments had only 0.131-0.201 times of application cost than that under manual weeding thrice. Herbicidal treatments resulted in 9.7-13.3 times higher marginal benefit: cost ratio over hand weeding thrice. Uninterrupted growth of weeds reduced the grain yield of maize by 63.5%.
