Abstract

ABSTRACT: The present study was to assess the additive effects of cuscuta (akasbel) aqueous extract alone and in combination with full and reduced doses of commercially available weedicides against weeds in wheat crop during the year 2016-2017. The study was conducted in a randomized complete block design (RCBD) with 3 replications. The results showed that hand weeding and use of weedicides Allymax and Axial (full and half recommended doses) significantly controlled all prevailing weeds and increased yield and yield contributing parameters over the weedy check/control and sole application of cuscuta aqueous extract. Hand weeding and Allymax (full dose) showed minimum weed population, relative density, fresh and dry weed biomass and higher leaf area index (LAI), leaf area duration (LAD), crop growth rate (CGR), plant height, 1000 grain weight and grain yield while net assimilation rate (NAR), chlorophyll content, number of tillers, spike length, grains spike-1 and biological yield were maximum only in hand weeding. These findings suggest that in order to attain highest wheat yield, the field should be kept free from weeds by hand weeding (if labour is not a limiting factor) or use recommended dose of weedicide Allymax for efficient weed management in wheat.

小麦单用及与市售除草剂Allymax和Axial联合施用的杂草治理

摘要/ ABSTRACT摘要:本试验旨在评价2016-2017年间，库库马(akasbel)水提物单独使用以及与市售全剂量和减剂量除草剂联合使用对小麦杂草的加性效应。本研究采用随机完全区组设计(RCBD)，共3个重复。结果表明，手除草和使用除草剂Allymax和Axial(推荐剂量为全量和半量)能显著控制所有杂草，并提高产量和产量贡献参数。手工除草和Allymax(全剂量)的杂草数量、相对密度、鲜、干杂草生物量最小，叶面积指数(LAI)、叶面积持续时间(LAD)、作物生长率(CGR)、株高、千粒重和籽粒产量较高，而净同化率(NAR)、叶绿素含量、分蘖数、穗长、穗1和生物产量只有手工除草最大。这些结果表明，为了获得最高的小麦产量，应通过手工除草(如果劳动力不是限制因素)或使用推荐剂量的除草剂Allymax进行有效的小麦杂草管理。
