“…These results highlight the superiority of line sowing in promoting plant height during the later stages of growth. Similar result was obtained from Ullah et al (2018) who reported 8% increase in plant height in line sowing compare to broadcast. Results also matched with the finding of Singh et al (2023), and Khatri et al (2019).…”

In this study conducted in Gadhawa Rural Municipality, Dang district, from November 2021 to April 2022, the impact of two sowing methods (Line sowing and broadcasting) and four varieties (Bijaya, Gautam, Aditya, and Borlaug 2020) on wheat was investigated. We aimed to identify the best sowing method and variety using a randomized complete block design with three replications. The study focused on various growth and yield parameters, including plant height, tiller number, grain per spike, effective tillers per square meter, thousand grain weight, grain yield per hectare, and biological yield per hectare. Line sowing was found to have the highest impact on biometrical as well as yield attributing characters. More height (111.51 cm), number of tillers (3.80), grain/spike (57.02), and grain yield (3.85 ton/ha) were obtained in line sowing. There was a significant difference observed among the varieties for all the traits except tiller number and biological yield. Borlaug 2020 was found to be superior for performance based on yield attributing traits which have grain/spike, effective tiller/m2, biological yield, and grain yield of 62.88, 177.15, 6.60 ton/ha, and 3.95 ton/ha respectively. From the interaction effects, variety Borlaug 2020 and line sowing method were found to be superior for cultivation. The study further demonstrates that farmers of Dang can combine Borlaug 2020 with line-sowing methods to obtain promising results.

“…Lesser weed prevalence results in better yield, while more weed infestation significantly reduced yield [ 58 ]. Adoption of suitable sowing techniques can suppress weed infestation, which ultimately affects crop yield [ 59 ]. In CTW, soil is inverted [ 11 ], which eradicates weeds [ 12 ] and makes soil well pulverized, which favors root development and lesser weed-crop competition [ 60 ].…”

Pakistan and other South Asian countries rely on wheat for human nutrition. However, wheat yield is declining in the region due to several biotic and abiotic constraints. Weeds are among the major factors responsible for yield decrease and farmers manage them by intensive tillage practices. Several studies have investigated the impact of various tillage practices on weed management in wheat. However, weed suppression abilities of different mulch types are rarely tested. This three-year (2019–20, 2020–21 and 2021–22) study investigated the impact of different mulch types (prepared from different crops) on weed infestation, soil properties and productivity of wheat under conventional and conservation production systems at three locations (Multan, Hafizabad and Faisalabad) in Punjab, Pakistan. The mulches included in the study were cotton sticks mulch, mungbean straw mulch, sorghum straw mulch, rice straw mulch, sunflower straw mulch, plastic mulch, and no mulch (as control). The production systems opted for wheat cultivation were conventionally tilled wheat (CTW), zero-tilled wheat (ZTW) and zero-tilled wheat sown with happy seeder machine (HSW). The CTW resulted in the lowest soil bulk density and the highest soil porosity after wheat harvest, while ZTW behaved oppositely. Similarly, incorporation of crop mulches resulted in the highest soil porosity and the lowest soil bulk density, while no-mulch incorporation and plastic mulch recorded the highest bulk density and the lowest soil porosity. Regarding mulches by production systems’ interaction, CTW with sorghum straw- and plastic mulches recorded the lowest weed density and biomass, while ZTW with no-mulch recorded the highest weed density and biomass at all locations. The CTW with mungbean straw- and plastic mulches resulted in the highest yield due to significant improvement in yield-related traits. However, ZTW with sorghum straw mulch and no-mulch resulted in the lowest wheat yield. Although sorghum straw mulch suppressed weed infestation, it negatively affected wheat growth. Economic analysis revealed that CTW with mungbean straw mulch resulted in the highest gross and net incomes and benefit:cost ratio (BCR), while the ZTW with rice straw- and sorghum straw mulches produced the lowest gross and net incomes and BCR at all locations. Therefore, mungbean straw mulch is a viable option to improve wheat productivity and net economic returns under different agro-climatic conditions of Punjab, Pakistan.

“…As far as weeds concerned, transplanted rice has a clear edge over DSR (Chauhan and Johnson, 2009;Chauhan, 2012). Hence, among various factors affecting rice growth like fertilizer management and sowing dates (Abid et al, 2015), weed invasion is one of the most severe problems in aerobic rice (Khaliq et al, 2012, Muhammad et al, 2016Ullah et al, 2017) which caused reduction in grain yield up to 80% in DSR (Mahajan and Chauhan, 2015). DSR can be sown into a prepared seed bed or under zero-till (ZT) conditions which depends upon the production system.…”

-In direct seeded rice (DSR), flushes of weeds are encountered, and mostly subsequent herbicides need to apply to control weeds that appear later. A farmer friendly approach was hypothesized in present study to integrate the management strategies for water, soil and cost effective weed free rice production. Efficacy of various herbicides in weed control to improve the performance of aerobic rice grown under varying tillage and alternate water regimes was evaluated. Five weed management techniques (weedy check, weed-free, pendimethalin followed by manual weeding, pendimethalin + bispyribac sodium (BS) + bensulfuron (B) and pendimethalin + MCPA) were carried out within the alternate wetting and drying (AWD) regimes (15 and 20 cm depth) under two tillage systems (zero and conventional). All the herbicide treatments reduced the weed intensity as compared to weedy check, however minimum weed density and dry biomass was observed in pendimethalin at 40 and 60 days after sowing, respectively. Under conventional tillage, weed free plots showed maximum leaf area index, leaf area duration and crop growth rate. Maximum plant height, 1000-kernel weight and kernel per panicle along with less percentage of abortive, chalky and opaque kernels were recorded in pendimethalin followed by BS+B as compared to weedy check plots. Among the herbicides application, pendimethalin followed by BS+B gave highest benefit to cost ratio and net benefits under both AWD regimes. Overall, application of pendimethalin followed by BS+B is an efficient and economic approach to reduce weed infestation which results in improved yield of aerobic rice.Keywords: aerobic rice, herbicides, irrigation management, benefit-cost ratio. RESUMO -Em arroz semeado direto (DSR), são encontradas descargas de plantas daninhas, e a maioria dos herbicidas subsequentes precisam se aplicar para controlar as plantas daninhas que aparecem mais tarde. Uma abordagem amigável ao agricultor foi hipotetizada no presente estudo para integrar as estratégias de manejo de água, solo e produção de arroz sem ervas econômicas. Foi avaliada a eficácia de vários herbicidas no controle de plantas daninhas para melhorar o desempenho do arroz aeróbio cultivado em lavoura variável e regimes alternativos de água. Foram realizadas cinco técnicas de manejo de plantas daninhas (controle de plantas daninhas, sem plantas daninhas, pendimetalina, seguidas de remoção manual, pendimethalin + bispyribac sodium (BS) + bensulfuron (B) e pendimethalin + MCPA) nos regimes alternativos de molhagem e secagem (AWD) (15 E 20 cm de profundidade) sob dois sistemas de preparo do solo (zero e convencional). Todos os tratamentos de herbicidas reduziram a intensidade da planta daninha em comparação com a verificação de plantas daninhas, porém a Copyright:This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided that the original author and source are credited.
