“…Significantly lowest cormel yield of taro was recorded in weedy plot may be due severe competition to taro plants for nutrients, light, soil moisture, space and air with unchecked weeds that reflected in reduction of growth as well as yield characters and in turn, realization of lowest cormel yield. Similar findings were also observed by Singh et al,2016 [10] in sweet potato, Singh et al, 2018 [11] in elephant foot yam, and Nedunchezhiyan et al 2017 [7] in cassava.…”

An experiment was conducted to find out most suitable weed management practices for weed management in taro during the year 2021-22 to 2022-23 at Agricultural Research Farm, Dholi of Tirhut College of Agriculture under Dr. Rajendra Prasad Central Agricultural University, Pusa (Bihar) in sandy loam soil in randomized block design having eight treatments [T1-Application of quizalofop ethyl @ 75 g a.i./ha at 25 DAP + Application of glyphosate 41 SL @ 1000 g a.i/ha at 45 & 90 DAP; T2-Application of quizalofop ethyl @ 75 g a.i./ha at 25 DAP + Hand weeding at 45 and 90 DAP; T3-Hand weeding at 30 DAP+ Application of glyphosate 41 SL @ 1000 g a.i/ha at 60 and 90 DAP; T4-Sowing cow pea in interspaces and incorporation at 45 DAP + Application of glyphosate 41 SL @ 1000 g a.i/ha at 90 DAP; T5-Mulching with black polythene sheet; T6-Straw mulching in interspaces ; T7-Complete weed free (hand weeding at 30, 60 and 90 DAP); T8-Control (weedy plot)] with three replications. It was found that significantly lowest weed population (8.73/ m 2 ) and weed dry weight (2.38 g/ m 2 ) was recorded in T5 than weedy plot and found at par with other weed management practices and the extent of reduction was to the tune of 82.02 to 94.82 and 92.94 to 98.09 percent, respectively with respect to weedy plot. Plant height, number of green leaves/plant, number of tillers/plant recorded in T7 was significantly higher than weedy plot and the increase were to the tune of 42.96 to 60.19, 26.62 to 46.54 and 42.32 to 60.75 percent, respectively. Similar trend was also noticed for corm and cormel yield/plant, number co cormels/plant and corm and cormel yield on hectare basis. The extent of increase in cormel yield was to the tune of 54.22 to 81.12 percent respectively with respect to weedy plot which may be may be due to the effective weed control of weeds from the field during the crop period that kept almost weed free situation and provided environment of least competition for growth factors to taro plants and loosening of soil by hand weeding thrice favoured aeration in the root zone and congenial condition for cormel bulking of taro. In fact, yield of cormel is the cumulative effect of growth factors and yield attributes that ultimately reflected in yield realization. Net return in all the treatments of weed management was significantly higher than that of weedy plot and the increase in net return ranges from 113.27 t to o 84.04 percent but B: C ratio did not follow the same trend as above. Significantly higher value of B: C ratio was recorded in T5 and the increase was to the tune of 77.48 to 22.10 percent as compared to weedy plot.

An experiment was conducted at College Farm, College of Agriculture, Rajendranagar, Hyderabad during rabi 2020-21 on loamy sand soils to study energy balance of weed management practices in mustard. The energy balance studies were determined by using direct and indirect energy. Among the different weed management practices, Stomp 30 % EC as PE fb straw mulch 5 t ha-1 recorded higher energy input. This treatment was followed by Goal 23.5 % EC as PE fb straw mulch 5 t ha-1 and Raft 6 % EC as PE fb straw mulch 5 t ha-1. Maximum energy output, net energy, energy use efficiency and energy productivity were noticed under intercultivation and hand weeding at 15 and 30 DAS and it was statistically on par with Raft 6 % EC as PE fb intercultivation at 30 DAS, Goal 23.5 % EC as PE fb intercultivation at 30 DAS and Stomp 30 % EC as PE fb intercultivation at 30 DAS.

“…It is a cosmopolitan insect and found on both the leaf surfaces and in leaf folds of developing heads, on leaf stalks, and on leaf axils. They are found primarily on the growing points of the host plants, including tips, flowers and developing pods and cover the whole plant with high density" [3,4]. "They suck sap from the hosts and infested plants become stunted and distorted.…”

The research was carried out at Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, Central Research Field, during Rabi season from november 2023- march 2024. The insecticide management experiment was conducted under Randomized Block Design (RBD) with the eight treatments and three replications by undertaking two spraying with fifteen-day intervals. The insecticides tested significantly reduced the pest population compared to control. Among the eight treatments evaluated for their efficacy in field condition against mustard aphids was recorded in treatment Neem oil 5% + Imidacloprid 17.8 SL (6.95) which was the minimum aphid population, followed by Imidacloprid 17.8 SL (8.46), Neem oil 5% + Acetamiprid 20% SP (9.78), Acetamiprid 20% SP (10.45), Neem oil 5% + Cypermethrin 10% EC (11.27), Cypermethrin 10% EC (11.55) and Neem oil 5% (12.01). The maximum aphid population was recorded in control plot (23.33 per 5 plant). Based on the results obtained in the investigation it is concluded that Imidacloprid 17.8SL with Neem oil and chemicals combined with neem oil could be utilized as a component in Integrated Pest Management of Lipaphis erysimi (Kalt.) on mustard. Similarly, the result revealed that the maximum C:B was recorded by treatment Neem oil 5%+ Imidacloprid 17.8% SL (1:2.77) followed by Imidacloprid 17.8% SL (1:2.67) and the minimum Cost Benefit Ratio was recorded in the control plot (1:1.27). The combination of Neem oil 5% and Imidacloprid 17.8 SL has offered cost-effective solutions that they effectively control aphid populations at lower costs. Thus, integrated pest management (IPM) approaches combining chemical treatments with cultural, biological, and mechanical controls may provide sustainable and cost-effective solutions in the long term.
