Abstract
Weed management in mungbean is one of the most efficient ways to improve its growth, as uncontrolled weed growth causes a significant decrease in crop growth. Effects of various herbicides applied at different rates as pre-emergence or as post-emergence were studied on growth characterstics in mungbean. It is usually infested and its growth parameter is adversely affected by a number of weed species that compete with the crop from germination to harvest, affecting the crop growth adversely. A field experiment titled “Effect of Different Weed Management Practices on Growth Characters of Mungbean under Mid-hills of Himachal Pradesh” was conducted during the kharif season of 2022 at Chamelti Agriculture Farm, MS Swaminathan School of Agriculture, Shoolini University of Biotechnology and Management Sciences, District Solan. The soil of the experimental field was sandy loam in texture, slightly alkaline in reaction with EC in a safer range, medium in organic carbon, available nitrogen, potassium, and high in available phosphorus. The experiment was laid out in randomized block design with three replications comprising ten weed management treatments viz. (T1) Pendimethalin 30 EC @ 1.0 kg a.i. ha-1 PE, (T2) Pendimethalin 30 EC @ 1.0 kg a.i. ha-1 PE fb one HW at 20 DAS, (T3) Pendimethalin 30 EC @ 0.75 kg a.i. ha-1 PE fb Imezathapyr 10% SL @ 70 g ha-1 PoE at 20 DAS, (T4) Pendimethalin 30 EC @ 0.75 kg a.i. ha-1 PE fb Oxyfluoren @ 50 g a.i. ha-1 PoE at 25 DAS, (T5) Pendimethalin @ 0.75 kg a.i. ha-1 PE fb Quizolofop ethyl @ 50 g ha-1 PoE at 20 DAS, (T6) Imazethapyr 10% SL @ 70 g a.i. ha-1 PoE at 20 DAS, (T7) One-hand weeding at 25 DAS, (T8) Two-hand weeding at 20 and 35 DAS, (T9) Weedy check and (T10) Weed free. The recommended dose of fertilizer (20:40:20 kg ha-1) was applied through Urea, SSP, and MOP at the time of sowing. Pusa Baishaki variety of mungbean was used for sowing. Weed management practices were done as per treatment. Other crop management practices were followed as per the recommendation of the area. Data on growth characters revealed that application of (T2) Pendimethalin 30EC @ 1.0 kg a.i. ha-1 PE fb one HW at 20 DAS registered higher growth parameters viz. plant height, number of branches plant-1, dry matter accumulation and trifoliate leaves which was statistically at par with (T3), (T4) and (T5). Thus, study suggest that mungbean can successfully grown under Mid-hills of Himachal Pradesh on (T2) Pendimethalin 30 EC @ 1.0 kg a.i. ha-1 PE fb one HW at 20 DAS.
