Wheat, a critical crop for global food security, faces significant challenges from weed infestation, which can drastically reduce yields. This study, conducted over two years at Sri Durga Ji P.G. College in Chandeswar, Azamgarh, U.P., investigated the efficacy of various herbicide treatments on the growth and yield of wheat using a Randomized Block Design. Key treatments included a weed-free control (T12), combinations of Sulfosulfuron with Metsulfuron (T2), and Pendimethalin with hand weeding (T10). The study found that comprehensive weed management strategies, particularly those combining multiple herbicides, significantly enhanced spike density, spike length, number of spikelets per spike, and overall grain yield. While the weed-free condition consistently showed the highest growth parameters and economic returns, it also incurred the highest cultivation costs. Conversely, the weedy check (T11) demonstrated the detrimental effects of uncontrolled weeds, showing the lowest growth and yield. Overall, effective herbicide management not only improves wheat productivity but also contributes to economic returns, underscoring the need for meticulous weed control in wheat cultivation.

“…Research and development in Bangladesh have developed effective CA practices for smallholder farms in the EGP using minimum soil disturbing implements mounted on 2WTs. The key outcomes are new knowledge developed on: (i) effective strip planting using the VMP [4][5][6]; (ii) planting machinery development and performance testing in the small fields using 2WTs [4,9]; (iii) agronomy for mechanised seeding with minimum soil disturbance and residue retention [5,6]; (iv) weed dynamics and weed management under CA [11][12][13][14][15][16]33]; (v) crop rotation effects on soils and weeds [33,34]; (vi) mechanised transplanting of NPT rice [24,25]; (vii) soil improvement under CA [17][18][19][20][21][22]; (viii) decreased greenhouse gas emissions under CA [23]; (ix) increased profit from CA-based SP + NPT rice in farmers' fields [8]; (x) water balance [27], which showed that wheat under CA (SP and increased residue retained) required 11-33% less irrigation water than the convention practices; and (xi) commercialisation models for sales of planters to LSP [31]. Based on the evidence presented, there should now be sufficient confidence for more widespread demonstrations across different agro-ecosystems in the EIP and for programmes to engage the private sector and farmers in adoption and out-scaling of CA for smallholder rice-based crop production in the EGP.…”

“…Experiments were conducted to assess the effectiveness of herbicide and/or crop residue use to control weeds under CA in a range of crops. The benefit-cost ratio (BCR) with SP and NPT followed by the application of pre-emergence and post emergence herbicides was much greater than for CT and CP and hand weeding [11,12]. Retention of 50% residue increased the grain yield by 4% and BCR by 9%.…”

“…Field experiment showed that application of herbicides has significantly reduced weed infestation in wheat and rice fields under SP and provided up to 227% and 28% higher grain yield of SP-based wheat and NPT-based rice, respectively, compared to non-weeded plot [11,12].…”

“…Selection of herbicides with different modes of action is an essential tool to minimize the risk of herbicide resistance developing in weeds. From several papers [11][12][13][14][15][16], it can be concluded that rotational use at the recommended dose of the effective herbicides in a rice-wheat-mung bean pattern could be effective to control weeds in the CA system as the herbicides applied to rice and wheat had no residual effect on the succeeding crops. Moreover, almost all rice and wheat varieties were tolerant to herbicides at the recommended rate on the product label.…”

We review the recent development of Conservation Agriculture (CA) for rice-based smallholder farms in the Eastern Gangetic Plain (EGP) and the underpinning research on agronomy, weed control, soil properties and greenhouse gas emissions being tested to accelerate its adoption in Bangladesh. The studies are based mostly on minimum soil disturbance planting in strip planting (SP) mode, using the Versatile Multi-crop Planter (VMP), powered by a two-wheel tractor (2WT). One-pass SP with the VMP decreased fuel costs for crop establishment by up to 85% and labour requirements by up to 50%. We developed strip-based non-puddled rice (Oryza sativa) transplanting (NPT) in minimally-disturbed soil and found that rice grain yield increased (by up to 12%) in longer-term practice of CA. On farms, 75% of NPT crops increased gross margin. For non-rice crops, relative yield increases ranged from 28% for lentil (Lens culinaris) to 6% for wheat (Triticum aestivum) on farms that adopted CA planting. Equivalent profit increases were from 47% for lentil to 560% for mustard (Brassica juncea). Moreover, VMP and CA adopting farms saved 34% of labour costs and lowered total cost by up to 10% for production of lentil, mustard, maize (Zea mays) and wheat. Effective weed control was obtained from the use of a range of pre-emergent and post-emergence herbicides and retention of increased crop residue. In summary, a substantial body of research has demonstrated the benefits of CA and mechanized planting for cost savings, yield increases in many cases, increased profit in most cases and substantial labour saving. Improvement in soil quality has been demonstrated in long-term experiments together with reduced greenhouse gas emissions.
