 ABSTRACT

A field experiment on “Integrated Weed Management in Ajwain (Trachyspermum ammi sprauge)” was conducted during rabi2012 at College farm, Rajendranagar, Hyderabad.The soil of the experimental site was sandy loam in texture, low in available nitrogen and low in available phosphorus and medium in available potassium. The experiment was laid out in randomized block design with three replications and thirteen treatments.Hand weeding gave significantly higher seed (1,155 kg ha-1), haulm (1,316 kg ha-1) yields and nutrient uptake (N-142.20; P-40.90; K-109.15kg ha-1) over all other treatments. Among integrated weed control treatments, oxyfluorfen @ 0.12 kg a.i ha-1 as PE  fb quizalfop -p-ethyl @ 0.05 kg a.i ha-1 as PoE at 20 DAS proved efficient in recording higher weed control efficiency (72.68%), seed (1,019 kg ha-1) and haulm (1,222 kg ha-1) yields with better weed index  (11.77). This was closely followed by oxyfluorfen @ 0.12 kg a.i ha-1 as PE fb hand weeding at 40 DAS which recorded a seed yield of 959 kg ha-1 with a weed index of 16.97.
