Impact of Imidazolinones on Weeds in Pigeon Pea (Cajanus cajan L.)

Background: Among various biotic factors limiting pigeon pea yield, weeds are of prime importance which can causes seed yield losses up to 80 per cent. Therefore current study aims evaluate the impact imidazolinones on in (Cajanus cajan L.). Methods: The experiment was laid out randomized block design using eighteen treatments replicated thrice. To control pea, alone and its combination with pendimethalin were applied rest other cultural practices for cultivation adopted according package CCA HAU, Hisar. Result: all weed controls treatments, two hoeing at 40 70 DAS found most effective kind weeds. PRE application comparatively more than POE application. different species, Cynodon dactylon not controlled by any herbicide treatment @ 1000 g/ha did Digera arvensis Cyperus rotundus. Whereas, + imazethapyr 75 provided best total leads lowest nutrient uptake Therefore, proved be an a profitable alternative existing recommendation (two 25 45 DAS) Haryana locality.
