Effect of Aqueous Extract of Sorghum Crop Residues on Weed Management and Crop Performance of Wheat

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to evaluate the effect of aqueous extract of sorghum crop residues on weed management and crop performance of wheat. The experiment consisted of three varieties of wheat viz., BARI Gom-19, BARI Gom-21, BARI Gom-24 and five different levels of treatments such as no use of aqueous extract, aqueous extract of sorghum crop residues: 1:20 ratio (w/v), 1:30 ratio (w/v), 1:40 ratio (w/v) and hand weeding. The experiment was laid out in a randomized complete block design with three replications. Seven weed species belonging to five families infested the experimental plots. Weed population, weed dry weight and percent inhibition of weed were significantly influenced by aqueous extract of sorghum crop residues and varieties. The maximum weed growth was noticed with the variety BARI Gom-19 and the minimum was found in the variety BARI Gom-21. The grain yield as well as the other yield contributing characters produced by BARI Gom-21 was the highest among the studied varieties. The highest percent inhibition for all of the weeds was found in hand weeding treatment. The second highest percent weed inhibition was occurred in aqueous extract of sorghum crop residues @ 1:20 ratio (w/v) treatment which was 51.81, 51.10, 52.90, 55.58, 75.27, 73.83 and 53.85 percent for bathua (Chenopodium album), mutha (Cyperus rotundus), durba (Cynodon dactylon), biskatali (Polygonum hydropiper), angta (Paspalum scrobiculatum), tit begun (Solanum torvum) and shama (Echinochloa crusgalli) respectively. The highest loss of grain yield was obtained where no aqueous extract of sorghum crop residues were used. The highest yield and yield attributes were observed where hand weeding is done followed by the application of aqueous extract of sorghum crop residues @1:20 ratio (w/v). Wheat var. BARI Gom-21 with all treatments produced the highest grain and straw yield among the treatment combination. The results of this study indicate that different amount of aqueous extract of sorghum crop residues showed potential activity to suppress weed growth and it has significant effect on the yield of wheat. Therefore, aqueous extract of sorghum crop residues might be used as an alternative way for weed management in effective and sustainable crop production Bangladesh Agron. J. 2018, 21(2): 87-95

Weed pressure is an additional threat to high temperature stressed wheat crop for its optimum production. A field experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during Rabi 2017-2018 to assess the response of wheat varieties to different weed managements and its economical viability. As such three varieties i.e. BARI Gom-28, BARI Gom-29, and BARI Gom-30 along with five weed managements viz. control (no weeding), two hand weeding at 20 and 40 DAS, Panida 33EC (Pendimethalin) @ 2000 ml ha-1 spray at 5 DAS as pre-emergence, Affinity 50.75 WP (Isoproturon) @ 1500 g ha-1 spray at 25 DAS as post-emergence and Panida 33EC (Pendimethalin) @ 2000 ml ha-1 at 5 DAS + Affinity 50.75 WP (Isoproturon) @ 1500 g ha-1 at 5 & 25 DAS were treatment variables tested under split plot design.Cynodon dactylon, Cyperus rotundus, Echinochloa colona, Eleusine indica, Chenopodium album, Alternanthera philoxeroides, Brassica kaber, Leliotropium indicum, Vicia sativa,etc.werethe major weeds as determined based on their field intensity.Results revealed that BARI Gom-30 out-yielded other varieties with the highest grain yield (3.01 t ha-1). Pre-emergence application of Panida 33EC at 5 DAS proved as suitable weed management compared to other methods. BARI Gom-30 in combination with Panida 33EC @ 2000 ml ha-1 spray at 5 DAS as pre-emergence gave higher yield and yield attributes while BARI Gom-28 under no weeding check showed lower grain yield (2.09 t ha-1). Economically maximum gross return (Tk.75761.52ha-1),net income (Tk.21775.92ha-1), and BCR (1.41) were associated with Panida 33EC treatment when minimum values were obtained in the control plot (no weeding). So, the application of pre-emergence herbicide, Panida 33EC might be economically viable weed management ensuring a higher yield in wheat cultivation. Bangladesh Agron. J. 2020, 23(2): 119-125

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during the period from June to December 2016 to evaluate the effect of marshpepper (Polygonum hydropiper L.) crop residues on weed management and crop performance of transplant aman rice. The experiment consisted of three cultivars viz. BR11, BRRI dhan33 and BRRI dhan49 and five marshpepper crop residues treatment such as 0, 1.0, 2.0, 3.0 ton ha-1 and hand weeding. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Five weed species belonging to four families infested the experimental plots. Weed population and weed dry weight were significantly affected by cultivar and crop residues treatment. The highest percent inhibition of all the studied weed was found by hand weeding. The second highest percent weed inhibition was found with the application of marshpepper residues at 3.0 t ha-1 which was 63.43, 63.43, 52.85, 52.40 and 59.12 percent for sabuj nakful (Cyperus difformis), chesra (Scirpus juncoides), shama (Echinochloa crusgalli) panikachu (Monochoria vaginalis) and panishapla (Nymphaea nouchali ) respectively. The maximum weed growth was noticed with the cultivar BRRI dhan33 variety and the minimum was found in the cultivar BRRI dhan49. The grain yield as well as the yield contributing characters produced by BRRI dhan49 was the highest among the studied varieties. The highest reduction of grain yield was obtained in no crop residue treatment. The highest number of effective tillers hill-1, number of grains panicle-1, 1000-grain weight, grain and straw yields were observed in marshpepper residues in hand weeding followed by 3.0 t ha-1 marshpepper crop residue. BRRI dhan49 produced the highest grain and straw yields under hand weeding followed by marshpepper residues 3.0 t ha-1 treatment. Results of this study indicate that marshpepper residues showed potentiality to inhibit weed growth and it has a significant effect on the yield of transplant aman rice. Therefore, marshpepper residues might be used as an alternative way for weed management effective and sustainable crop production. Progressive Agriculture 30 (4): 379-386, 2019

A Field experiment was conducted during the Kharif season of 2018 at Bihar Agricultural University, Sabour (Bihar) to evaluate the performance of different herbicides in aerobic rice (Oryza sativa L). Weed management had a positive influence on growth, yield attributes and yield of the aerobic rice. In experimental field, Cyperus rotundus, Cyperus iria, Cyperus difformis, Cynodon dactylon, Eleusine indica, Fimbristylis miliacea, Echinochloa colona, Echinochloa crus-galli, Commelina benghalensis, Caesulia auxillaris, Lippia nodiflora, Amaranthus spinosus, Oxalis acetosella, Amaranthus viridis, Eclipta alba, Phyllanthus niruri and Monochoria vaginalis were the dominant weed flora species. The results revealed that lowest weed population and weed dry weight were recorded in weed free situation which were significantly superior over rest of the herbicidal treatments. The maximum mean grain yield of aerobic rice (4.00 t/ha) was recorded by weed free which intern was statistically at par with the mean grain yield obtained from the herbicide Pyrazosulfuron fb one hand weeding (3.92 t/ha) followed by Pyrazosulfuron fb Bispyribac (3.88 t/ha), Bispyribac sodium (3.83 t/ha), Pyrazosulfuron+Ethoxysulfuron (3.62 t/ha), Bispyribac sodium+Pyrazosulfuron (3.61 t/ha) and Halosulfuron + Azimsulfuron (3.50 t/ha). Significantly lowest mean grain yield of (1.90 t/ha) was obtained from weedy check plots. The highest weed control efficiency (100%) was recorded under the treatment weed free which was followed by Pyrazosulfuron fb one hand weeding (85.96%), Pyrazosulfuron fb Bispyribac (84.77%), Bispyribac sodium (83.09%). All microflora (bacteria, fungi, actinomycetes) were recorded maximum number under the treatment weedy check. There were halosulfuron causes some phytotoxic effects at early stage on rice crop. The highest gross return (Rs.70,000/ha) was obtained by weed free which was statistically at par with Pyrazosulfuron fb one hand weeding (Rs.68,600/ha), Pyrazosulfuron fb Bispyribac(Rs.67,900/ha), Bispyribac sodium (Rs.67,025/ha), Pyrazosulfuron+Ethoxysulfuron (Rs.63,350), Bispyribac sodium+Pyrazosulfuron (Rs.58,800/ha) and significantly superior over rest of the treatments. However, the highest net return (Rs. 37,323/ha) was recorded by the treatment Pyrazosulfuron fb Bispyribac sodium which was found superior over rest of the treatments. The highest B:C ratio (Rs.2.22) was recorded by Pyrazosulfuron fb Bispyribac which was statistically at par with Bispyribac sodium (Rs.2.20), Pyrazosulfuron fb one hand weeding (Rs.2.19), Pyrazosulfuron+Ethoxysulfuron (Rs.2.13) and Bispyribac sodium+Pyrazosulfuron (Rs.1.91) all these were significantly superior over rest of the treatments.

Crop allelopathy may be useful to minimize serious problems in the present agricultural production such as environmental pollution, unsafe production, human health concerns, depletion of crop diversity, soil sickness and reduction of crop productivity. In this phenomenon an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to evaluate the effect of crop residues of mustard on weed management and crop performance of T. aman rice. The experiment consisted of three cultivars of T. aman rice viz., BR11, BR23 and BRRI dhan49 and five different level of mustard crop residues such as no crop residues, mustard crop residues @ 0.5, 1.0, 1.5 and 2.0 t ha–1. The experiment was laid out in a randomized complete block design with three replications. Five weed species belonging to three families infested the experimental plots. Weed population, weed dry weight and percent inhibition of weed were significantly influenced by mustard crop residues and cultivar. The maximum weed growth was noticed with the cultivar BR23 and the minimum was found in the cultivar BR11. The grain yield as well as the other yield contributing characters produced by BR11 was the highest among the studied varieties. The highest percent inhibition of 71.17, 69.19, 80.88, 70.48 and 86.97 was in Shama (Echinochlo acrusgalli), Panishapla (Nymphaea nouchali), Panichaise (Scirpus juncoides), Panikachu (Monochoria vaginalis) and Susnishak (Marsilea quadrifolia), respectively which was caused by the application of mustard crop residues @ 2 t ha–1. The highest loss of grain yield was obtained where no crop residues were incorporated. The highest numbers of tillers hill-1, numbers of grains panicle–1, 1000-grain weight, grain yield, straw yield were observed where mustard crop residues were incorporated @ 2.0 t ha–1. BR11 cultivar with all treatments produced the highest grain and straw yield among the treatment combination. The results of this study indicate that different amount of mustard crop residues showed potential activity to suppress weed growth.J. Bangladesh Agril. Univ. 15(2): 133-139, December 2017

A field experiment was conducted during rabi seasons of 2007-08 and 2008-09 on mollisols at G.B. Pant University of Agriculture & Technology, Pantnagar to study the performance of fieldpea (Pisum sativum L.var arvense) under different planting methods, irrigation levels and weed management practices. Results revealed that growth attributes as plant height, number of branches and dry matter accumulation per plant, number and dry weight of nodules per plant, density and dry matter of weeds/unit area, nutrient uptake and yield attributes as pods/plant, 1000-grain weight, grain yield/plant and grain yield of fieldpea were significantly higher under raised bed planting as compared to flat bed. Planting on raised bed increased grain yield of fieldpea by 17.5% over flat bed. Two irrigations applied at critical stages i.e. pre-flowering and pod formation proved promising in increasing the growth, nutrient uptake, yield attributes and grain yield of pea. One hand weeding done at 25 days after sowing (DAS) reduced the density and dry matter of weeds significantly and one hand weeding done at 25 DAS increased the values of growth attributes, number and dry weight of nodules, nutrient uptake, yield attributes and grain yield as compared to pendimethalin 1.0 kg a.i./ha applied as pre-emergence and weedy check.
