Abstract: An experiment entitled "Effect of Herbicides on Growth, Yield and Economics in Soybean (Glycine max L.)" was conducted in Kharif season 2015 at research farm of BRAUSS, MHOW, (M.P.). The soil of the experimental field was medium black in texture, neutral in reaction (pH 7.60) with normal EC (0.45 dS/m) and medium organic carbon contents (0.72%) and analysing low in available N (270 kg/ha), medium in available P (6.9 kg/ha) and high in available K (382 kg/ha) contents. Due to dominance of montmorillonite clay content it has high capacity to swell and shrink and high CEC. A field experiment was consisted of 9 treatments replicated four times in randomized block design (RBD). As per treatment, the seed of soybean cv. JS 335 was sown in all the treatments consisting with pre and post emergence herbicides. The maximum number of pods (30.90) and seed weight (11.10 g) was recorded under treatment T9-weed free plot followed by T4-fenoxaprop-p-ethyl, which gave the value of 27.60 pods/plant and 11.0 g seed index. The lowest number of pods (26.60) and seed index (9.20) was recorded under treatment T8-control. The highest grain and stover yield (14.33 and 15.52 q/ha) was recorded under treatment T9-weed free plot followed by (14.0 and 14.73 q/ha) under treatment T4-fenoxaprop-p-ethyl 9% EC while lowest grain and stover yield (9.14 and 11.38 q/ha) was obtained under treatment T8 (control). The highest net return (Rs.32796/ha) was obtained under the treatment T9 (weed free situation) closely followed by T4 fenoxaprop-p-ethyl 9% EC (Rs.32359/ha) while the lowest net return (Rs.18284/ha) was received under the treatment T8 (control). The highest benefit: cost ratio (2.30) was obtained under the treatment T4-Fenoxaprop-p-ethyl 9% EC closely followed by T3 -Chlolrimuron-ethyl 25% WP (2.29) and T9 (weed free situation) (2.20) while the lowest benefit:cost ratio (1.45) was received under the treatment T8 (control).
