Abstract:

An experiment entitled "Influence of pre and post-emergence herbicides on weed dynamics, growth and yield of 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 treatment T4- Fenoxaprop-p-ethyl 9 % EC, 67.5 g/ha post eme. (20 DAS) showed weed index or minimum decline (2.3 %) in seed yield. Among other treatments minimum decline (4.95 %) was recorded under treatment T5- Chlorimuron ethyl + Fenoxaprop-ethyl, 9.37 g/ha + 67.5 g/ha, post emergence while highest yield decline (36.22 %) was observed under control (T8). Weed control efficiency (WCE) was relatively higher in T9-weed free plots (98.25 %), T4-fenoxaprop-p-ethyl (97.98 %) and T5-Chlorimufon-ethyl + fenoxaprop-p-ethyl (97.84 %) than rest of the treatments. The highest grain (1.43 t/ha) and stover yield (1.55 t/ha) was recorded under treatment T9-weed free plot followed by 1.4 t/ha and 1.47 t/ha under treatment T4-fenoxaprop-p-ethyl 9% EC while the lowest grain (0.91 t/ha) and straw yield (1.14 t/ha) was obtained under treatment T8 (control).
