The present study was conducted in kharif seasons of 2015, 2016 and 2017 at experimental farm of Rajasthan Agricultural Research Institute, Durgapura, Jaipur (Rajasthan) to study efficacy of different weed management practices in clusterbean. Three years result shows that compared to weedy check (6.82 m-2) application of Pendimethalin @ 0.75 kg a.i. ha-1 as PE fb one hand weeding recorded lowest weed density (3.58 m-2). Among herbicidal treatments, Pendimethalin @ 0.75kg a.i/ha as PE fb one hand weeding at 25 DAS (83.7%) and Pendimethalin @ 0.75 kg a.i./ha as PE+ Imazathapyr+ Imazamox @ 40g a.i./ha PoE (74.0%) recorded highest weed control efficiency. Likewise, application of Pendimethalin @ 0.75kg a.i/ha as PE fb one hand weeding at 25 DAS and Pendimethalin 0.75kg/ha at PE fb Imazathapyr + Imazamox @ 40g a.i. ha-1 recorded significantly higher seed (1136 kg ha-1 and 1009 kg ha-1), haulm (3304 kg ha-1 and 2943 kg ha-1) and biological yield (4440 kg ha-1 and 3953 kg ha-1), respectively over other herbicidal treatments. Economic evaluation indicated that application of Pendimethalin @ 0.75kg a.i/ha as PE fb one hand weeding at 25 and which was followed by with Pendimethalin @ 0.75 kg a.i./ha as PE+ Imazathapyr+ Imazamox@ 40g a.i./ha recorded, gross return (INR 55352 ha-1 and INR 49189 ha-1) net returns (INR 38852 ha-1 and INR 34289 ha-1) and B:C ratio (2.35 and 2.20), respectively. Whereas, minimum cost of cultivation (INR 10000 ha-1) and gross returns (INR 25632 ha-1), net returns (INR 15632 ha-1) and B:C ratio (1.56) were recorded under weed check. So looking to the laborious pressure of hand weeding, cost effectiveness ease of application of chemical herbicides, application of Pendimethalin 0.75 kg ha-1 fb one hand weeding can be an effective weed control option in cluster bean crop with higher seed and haulm yield under Semi-arid and Arid regions of Rajasthan.

Hand Weeding

A field experiment was conducted at Research Farm of Agricultural Research Station, Ummedganj, Kota (Agriculture University, Kota), Rajasthan, India during kharif 2019 to find out the most effective herbicide combination for limiting the menace of weeds in maize. Results showed that density of monocot weeds were observed more than dicot weeds during the experimentation. The prominent weeds were Echinochloa colona, Cyperus rotundus, Digera arvensis, Amaranthus viridis, Acalypha indica and Trianthema portulacastrum etc. caused about 58.3% reduction in grain yield as over two hand weeding at 20 and 40 DAS. In general, grassy weeds were better controlled by herbicides than broad leaves weeds. Among herbicides, maximum weed control efficiency (72.18%) was achieved with application of atrazine 500 g a.i. ha-1 (PE) followed by topramezone 25.2 g a.i. ha-1 at 20-25 DAS (72.18%) which is very close to two hand weeding at 20 and 40 DAS. Furthermore, this treatment also produced higher grain (3496 kg ha-1) and stover yield (6460 kg ha-1) which was at par with atrazine 500 g a.i. ha-1 (PE) followed by tembotrione 120.75 g a.i. ha-1 (20-25 DAS) and atrazine 500 g a.i. ha-1 (PE)+hand weeding 30 DAS with in-situ weeds mulching. Thus, pre-emergence application of atrazine 500 g a.i. ha-1 (PE) followed by topramezone 25.2 g a.i. ha-1 at 20-25 DAS is recommended for better weed control and yield of maize.

A field experiment was conducted during Kharif seasons of 2014 and 2015 at Udaipur (Rajasthan) to find out the effect of weed management on productivity of clusterbean under varying fertility levels. The results revealed that among various weed management practices, two hand weeding 20 and 40 DAS recorded significantly lower weed dry matter, higher weed control efficiency, higher values of yield attributes, seed, haulm and biological yield during both the years over rest of the treatments except sequential application of pendimethalin fb imazethapyr which was statistically at par. Further, application of Imazethapyr fb hand weeding and pendimethalin fb hand weeding also gave comaparable results with pendimethalin fb imazethapyr in terms of weed control efficiency and yields. Among the fertility levels application 20 Kg N + 40 Kg P2O5 ha-1 significantly increased pods plant-1 (24.04), seeds pod-1, (7.12), test weight ( 25.33 g), seed ( 1035 kg ha-1), haulm (2161 kg ha-1) and biological (3196 kg ha-1 ) yield and harvest index ( 31.98 %) of clusterbean over 10 Kg N + 20 Kg P2O5 ha-1 however, it was found statistically at par with fertility level 30 Kg N + 60 Kg P2O5 ha-1. Therefore, clusterbean should be fertilized with 20 Kg N + 40 Kg P2O5 ha-1 and weeds must be controlled with pendimethalin (PE) fb imazethapyr 0.1 kg ha-1 20 DAS .

A Field experiment was conducted at Agronomy instructional Farm, Rajasthan College of Agriculture, MPUAT, Udaipur (Rajasthan) during 2016-17 to find out the impact of new generation herbicides in green gram.  The results revealed that all growth and yield characters of blackgram were significantly affected by distinct weed control practices. A similar trend was also observed in weed parameters. Higher seed yield (13.8 qha-1) and higher weed control efficiency (88.97%) were recorded under application of acifluorfen sodium + clodinafop propargyl (370 g a.i. ha-1) at 3-4 leaf stage and which comparable with pre-emergence application of pyroxasulfone +pendimethalin (TM) 127.5+1000 g a.i/ha, imazethapyr+ quizalofop (TM) use at 70 + 60 g a.i/ha at 3-4 leaf stage, imazethapyr 70 g a.i/ha 3-4 leaf stage, imazethapyr + imazamox (RM) use at 70 g a.i/ha at 3-4 leaf stage, pendimethalin fb quizalofop 1000 + 60 at pre-emergence & 3- 4 leaf stage, imazethapyr + pendimethalin (RM) 1000 g a.i/ha as pre-emergence, propaquizfop 75 g a.i/ha at 3-4 leaf stage, weedy check and two hand weeding twice at 20 & 40 DAS. They also recorded improvement in yields and net returns by 65.22% over weedy check. These herbicide ready-mixes may be a promising weed management strategy for the green gram grown in the Southern Rajasthan.

The Impact

Integrated weed management (IWM) has been part of cranberry cultivation since its inception in the early 19th century. Proper site and cultivar selection, good drainage, rapid vine establishment, and hand weeding are as important now for successful weed management as when the industry first started. In 1940, Extension publications listed eight herbicides (e.g., petroleum-based products, inorganic salts and sulfates) for weed control. Currently, 18 herbicides representing 11 different modes of action are registered for use on cranberries. Nonchemical methods, such as hand weeding, sanding, flooding, and proper fertilization, remain integral for managing weed populations; new tactics such as flame cultivation have been added to the toolbox. Priority ratings have been developed to aid in weed management planning. Despite many efforts, biological control of weeds remains elusive on the commercial scale. Evaluation of new herbicides, unmanned aerial systems (UAS), image analysis, and precision agriculture technology; investigation of other management practices for weeds and their natural enemies; utilization of computational decision making and Big Data; and determination of the impact of climate change are research areas whose results will translate into new use recommendations for the weed control of cranberry.

A field experiment was conducted to analyze the types of flora, intensity, cover and effects on yields of coriander. Pooled analysis of data indicated that Goose foot (Chenopodium murale L.), Corn spurry (Spergula arvensis L.) among dicots and Purple nutsedge (Cyperus rotundus L.) among monocots were found most dominant weeds at all stages of crop growth. Of the total eight weed species reported dicot weeds were found most dominating weed species and comprises 78-80 percent of total weed density throughout crop cycle. All weed management practices significantly reduced the density of monocot and dicot weeds and improved the yield (seed and biological yield) of crop as compared to control. Two hand weeding at 30 and 45 DAS resulted in maximum reduction in total weed density and gave the highest seed (15.84 q/ha) and biological yield (41.11 q/ha) of coriander. However, seed and biological yields was obtained at par by pendimethalin 1.0 kg/ha + one hand weeding at 45 DAS. This treatment also resulted in favorably lowest weed competition index as compared to rest of other practices. Balanced fertilization with N+P+K+S also improved monocot and dicot weed density but the effect was not significant over N+P and N+P+K fertilization. N+P+K+S fertilization significantly enhanced crop seed and biological yields over N+P (1.86 q/ha and 4.36 q/ha, respectively) and N+P+K application (0.94 q/ha and 2.20 q/ha, respectively). Weed management and balanced fertilization practices also found to have significant interaction effect on seed and biological yield of coriander.

Chickpea (Cicer arietinum) is one of the most important pulse crops but it’s productivity in India is quite low. There are various reasons for low productivity. Weed control is the basic requirement and the major component of crop management. Weeds on an average reduce the crop yield by 40-87 per cent. Deciding time to control weeds requires detailed knowledge of the weed populations in the field. Different management practices like altering spacing, competitive cultivars, etc. can help in enhancing the productivity. With the world entering the precision-farming era, more emphasis is being put on the use of post-emergence herbicides. Application of two or more herbicide at the same time or as a double knockdown and integrating with hand-weeding provides desirable control of different weed species besides reducing the hazard of chemical weed control.

Oriental Mustard

The phase-out of methyl bromide required an effective and economically viable alternative for weed management in polyethylene-mulched tomato (Solanum lycopersicum). A field experiment was conducted to compare economics of tomato production associated with crucifer (Brassicaceae) cover crops under low-density polyethylene mulch (LDPE) and virtually impermeable film (VIF) mulch with a standard treatment of methyl bromide:chloropicrin (67:33) at 350 lb/acre. Three crucifer cover crops, ‘Seventop’ turnip (Brassica rapa), ‘Pacific Gold’ oriental mustard (Brassica juncea), and Caliente [a blend of brown mustard (B. juncea) and white mustard (Sinapis alba)], were evaluated in combination with hand-weeding. Because of marginal weed control from crucifer cover crops, hand-weeding cost in all cover crop plots, regardless of mulch type, increased from $380.54/acre to $489.10/acre over that in methyl bromide plots. However, total weed management costs in the untreated control and cover crops with LDPE treatments were $17.82/acre to $111.33/acre lower than methyl bromide. Because of mulch expenses, VIF mulch increased the total weed management cost by $328.16/acre over LDPE mulch in the untreated control and cover crop treatments. Because of equivalent marketable yield, gross returns ($21,040.43/acre) were identical in all treatments. Preplant fumigation with methyl bromide provided $6260.90/acre of net returns in tomato production. The untreated control, ‘Seventop’ turnip, ‘Pacific Gold’ oriental mustard, and Caliente mustard under LDPE treatment were $54/acre, $54/acre, $98/acre, and $147/acre more profitable, respectively, than methyl bromide. However, in all other treatments under VIF, net returns relative to methyl bromide were reduced from $181/acre to $274/acre. Therefore, regardless of soil amendment with crucifer cover crops, hand-weeding can serve as an economically viable alternative to methyl bromide for weed control in LDPE-mulched tomato production, depending on the nature and level of pest infestation, labor availability, and wages.

Field experiment on effect of different weed management practices in machine transplanted rice (Oryza sativa L.) was conducted at ARS, Gangavathi, University of Agricultural Sciences, Raichur, Karnataka during kharif, 2012 and 2013 under irrigated condition in clay soil. Pooled mean indicated that, application of butachlor 50 EC fb passing of power operated low land rice weeder twice at 20 and 30 DAT with hand weeding in intra row space recorded significantly lower grassy weed population and dry weight at 40, 60 DAT and at harvest (1.98, 2.47, 2.97/0.25 m2 and 1.00, 1.20, 1.47 g /0.25 m2, respectively), sedge weed population and dry weight (2.61, 3.21, 3.52 /0.25 m2 and 1.19, 1.48, 1.71 g /0.25 m2, respectively) and broad leaved weed population and dry weight (1.68, 2.10, 2.52 / 0.25 m2 and 0.91, 1.06, 1.28 g /0.25 m2, respectively). Significantly higher WCE (87.53%), lower weed index (3.11 %), grain and straw yield (5160 and 6482 kg ha-1, respectively), gross and net returns (Rs. 92,212 and 50,410 ha-1, respectively), and B:C of 2.22 over unweeded check. Hence, application of butachlor 50 EC fb passing of power operated low land rice weeder at 20 and 30 DAT with hand weeding in intra row space was found to be the best weed control method as it recorded higher B:C. Present conventional manual weeding is which is not advantageous as it is costlier, time consuming and labour may trample and damage rice seedlings. Mechanical weeder and sequential application can overcome the same.
