Evaluation of Pre- and Post-emergence Herbicides in Gram (Cicer arietinum L.)

The present experiment was carried out at Instruction farm, College of Agriculture, Junagadh Agricultural University, Junagadh. During the year 2011–2012, to investigate the evaluation of pre- and post-emergence herbicides in gram (Cicer arietinum L.). Ten treatments comprising combination of pre-(oxyfluorfen & oxadiargyl) and post-emergence (oxadiargyl, quizalofop-ethyl & fenoxaprop-p-ethyl) herbicides including weed free and weedy check were tested in randomized block design with three replications. Premergence application of oxyfluorfen either 180 or 120 g ha⁻¹ or oxadiargyl 90 g ha⁻¹ were found effective to control different weed species. Frequent hand weeding under weed free condition was proved effective against all weed species. Being equivalent to weed free, maximum seed and stover yields ofgram were recorded under pre-emergence application of oxyfluorfen 180 g ha⁻¹followed by 1 HW & IC at 30 DAS and 2 HW & IC (at 30 and 45 DAS). Similarly, tend was found ingrowth parameter and number of pods per plant, nitrogen, phosphorus, potassium up take by weed and crop. Superiority of weed free and oxyfluorfen 180 g ha⁻¹ pre-emergence followed 1 HW & IC at 30 DAS also reflected in higher B:C ratio of 1.88 and 1.71, respectively.
