Abstract:
An experiment entitled "To study the effect of Chemical Weed Control on Growth and Yield of Soybean (Glycine max L.)" was conducted in Kharif season at student research field, College of Agriculture, Indore (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 numbers of branches/plant (3.38) was recorded in the treatment T9 (weed free plot) followed by T4-fenoxaprop-ethyl 9% EC (3.12), which was applied as post-emergence herbicide at 20 DAS at all the stages of crop growth. The maximum number of pods per plant (30.90), number of seeds per pod (2.30) and number of seeds per plant (58.00) was recorded under treatment T9 (weed free plot) while minimum number of pods (20.00) and seeds (46.0) per plant was recorded under treatment T5. The highest grain (1433 kg/ha) and stover yield (1552 kg/ha) was recorded under treatment T9 -weed free plot followed by 1400 kg/ha (grain) and 1473 kg/ha (stover) under treatment T4-fenoxaprop-p-ethyl 9% EC while the lowest grain yield (914 kg/ha) and stover yield (1138 kg/ha) was obtained under treatment T8 (control).
