Abstract:

A field experiment was conducted during kharif 2015 at college farm, College of Agriculture, Rajendranagar, Hyderabad to study the impact of new generation herbicide combinations on nodulation and leghemoglobin content of greengram (Vigna radiata L.) in South Telangana. The experiment was laid out in Randomized Block Design consisted of 11 treatments and 3 replications viz. pendimethalin @ 1.0 kg/ha as pre-emergence, pendimethalin followed by imazethapyr @ 75 g/ha as post-emergence (at 2-4 leaf stage), imazethapyr @ 75 g/ha, chlorimuron ethyl @ 9 g/ha, quizalofop ethyl @ 50 g/ha + imazethapyr @ 75 g/ha, imazethapyr + imazamox @ 70 g/ha, propaquizafop @ 50 g/ha + imazethapyr @ 75 g/ha, haloxyfop-p-methyl @ 135 g/ha + imazethapyr @ 75 g/ha, cycloxydim @ 80 g/ha + imazethapyr @ 75 g/ha, hand weeding at 20 and 40 DAS and unweeded control. The herbicide combinations were applied at 12-15 DAS. The results revealed that combinations of haloxyfop-p-methyl @ 135 g/ha + imazethapyr @ 75 g/ha, and quizalofop ethyl @ 50 g/ha + imazethapyr @ 75 g/ha applied 12-15 DAS were found promising for getting higher productivity without affecting the nodulation.
