EFFECT OF LONG-TERM TILLAGE, MULCH AND TIME OF NITROGEN APPLICATION ON MOST DOMINANT WEEDS IN WHEAT (TRITICUM AESTIVUM L.)
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2011, Vol 2, Issue 12
Abstract
A field experiment was conducted at the Research Block of Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan, Nepal during winter season of 2007/08 to assess the effect of longterm tillage, mulch and time of N application on most dominant weed species in wheat field. The experiment consisted of two levels of tillage (no tillage and conventional tillage), two levels of mulch (no mulch and mulch with rice straw @ 4 t ha-1) and two timings of nitrogen application (half at sprouting and half at CRI stage and half at CRI stage and half at 40 days after sowing) and was laid out in factorial RCBD with three replications. This experiment was the continuation of ongoing experiment conducted jointly by IAAS and Cornel University from 2002-2007. The data on dominant weeds were taken in 2007/08 to determine the impact of treatments for long term. Result showed that majority of the weed species were higher in surface seeding and no mulch plot at all the growth stage of the wheat. Time of nitrogen application had non-significant effect at 35 and 70 DAS of wheat but at maturity stage, majority of weeds were lesser in half N applied at sprouting and half N at CRI stage plot.
