The experiment was conducted at Regional Spices Research Centre, Bangladesh Agricultural Research Institute, Magura, Bangladesh during 2016-2017 and 2017- 2018 to optimize weed management practice for onion bulb production through Integrated Weed Management (IWM). The experiment was laid out in a Randomized Complete Block Design with three replications. Two different herbicides (Oxadiazon and Pendimethalin) with different doses in combination with hand weeding (HW) were used as treatments. The total number of treatments were 12 viz. [email protected] l/ha, [email protected] l/ha, T3= [email protected] l/ha, T4= [email protected] l/ha + one HW at 45 DAT (Days After Transplanting), T5= [email protected] l/ha + one HW at 45 DAT,T6= [email protected] l/ha + one HW at 45 DAT, [email protected] l/ha, [email protected] l/ha, T9= [email protected] l/ha + HW at 45 DAT, T10= [email protected] l/ha+ HW at 45 DAT, T11= Weed free and T12 = Weedy check (control). The onion var. BARI Piaz-1 was used as the test crop. The highest bulb yield (7.63 tha-1 in 2016 & 9.56 t ha-1in 2017) and benefit cost ratio (2.14 in 2016 and 2.46 in 2017) were obtained from T6= [email protected] l/ha + one hand weeding at 45 DAT while the lowest bulb yield (4.22 t ha-1in 2016 and 6.28 t ha-1in 2017) was obtained from T12 = Weedy check (control), while lowest benefit cost ratio (1.33 in 2016 and 1.74 in 2017) from treatment T11 =Weed free. It was concluded that [email protected] l/ha with one hand weeding at 45 days after transplanting performed better for controlling weed and maximizing bulb yield of onion. Bangladesh Agron.

The proven significance of conservation agriculture (CA) in enhancing agronomic productivity and resource use efficiency across diverse agro-ecologies is often challenged by weed interference and nitrogen (N) immobilization. The collective effect of real-time N and weed management has been scarcely studied. To evaluate the appropriateness of sensor-based N management in conjunction with a broad-spectrum weed control strategy for the maize–wheat system, an experiment was conducted at ICAR—Indian Agricultural Research Institute—in New Delhi, India, during 2015–2016 and 2016–2017. Weed management in maize through Sesbania brown manure followed by post-emergence application of 2,4-D (BM + 2,4-D) in maize and tank-mix clodinafop-propargyl (60 g ha−1) and carfentrazone (20 g ha−1) (Clodi+carfentra) in wheat resulted in minimum weed infestation in both crops. It also resulted in highest maize (5.92 and 6.08 t ha−1) and wheat grain yields (4.91 and 5.4 t ha−1) during 2015–2016 and 2016–2017, respectively. Half of the N requirement, when applied as basal and the rest as guided by Optical crop sensor, resulted in saving 56 and 59 kg N ha−1 in the maize–wheat system, respectively, over 100% N application as farmers’ fertilizer practice during the two consecutive years. Interactive effect of N and weed management on economic yield of maize and wheat was also significant and maximum yield was obtained with 50% N application as basal + rest as per Optical crop sensor and weed management through BM+2,4-D in maize and Clodi+carfentra in wheat crop. The study concludes that real-time N management, complemented with appropriate weed management, improved growth, enhanced agronomic productivity and endorsed N saving under a CA-based maize–wheat system in Trans Indo-Gangetic Plains.

Crop Management Systems

Integrated Weed Management (IWM), a long time practice by farmers has become more commonly discussed as a total weed management system. Whether an off shoot of Integrated Pest Management (IPM) or a further recognition of integrating weed control measures within the cropping and farming system, it has become more widespread. IWM is being practiced using many of the same components, from croplands to forests and rangeland. A weed management hierarchy has been developed by degree of diversity of management practices. IWM researchers and educators should invite other pest management specialists to join us in striving for Integrated Crop Management systems.

A field investigation was carried out during winter seasons of 2012-13, 2013-14 and 2014-15 at Agricultural Research Station, Gulbarga (Karnataka) to evaluate the effect of pre and post emergence herbicides on weeds and productivity of chickpea cv. JG-11. Ten treatments were tested in randomized block design with three replications. Among the herbicidal treatments, pendimethalin 38% CS 0.75 kg a.i ha-1PE + hand weeding (HW) at 30-35 days after sowing (DAS) and pendimethalin 30% EC 0.75 kg a.i ha-1+ imazethapyr 2% 1.0 kg a.i ha-1 PE + one hoeing at 30-35 DAS recorded significantly higher seed yield (1198 kg ha-1), net returns (Rs. 25107 ha-1) and B:C ratio (2.10) and lower weed dry weight (11.3 g m-2) and higher weed control efficiency (83%) than all other herbicidal treatments except two hand weedings at 20 and 40 DAS. It may be inferred from the present investigation that these herbicidal treatments could be used effectively as an alternative for controlling weeds and obtaining optimum seed yield of chickpea under rainfed conditions of Karnataka.

The Difference

The yield gap discussed in this paper is the difference between the potential farm yield and the actual average farm yield of rice is 1.92 t ha-1 in Bangladesh. The yield gap is mainly caused by physical, biophysical, socioeconomic and institutional factors. Different strategies, such as integrated crop management (improve adapted varieties, site specific nutrient management, locally adapted integrated weed management and optimized water management) practices, timely supply of inputs including credit to farmers, research and extension collaboration to transfer the new technologies have been discussed to minimize yield gap. Suggestions have been made to make credit available to resourcepoor small farmers to buy necessary inputs, reducing transaction cost, simplifying lending procedures and strengthening monitoring mechanism of the current credit system are, however, essential to enable the farmers to avail the credit facility. Efforts should be made to update farmers’ knowledge on the causes of yield gaps in crops and measures to narrow the gaps through training, demonstrations, field visits and monitoring by extension agencies to achieve high yield. Based on present yield gap of rice (1.92 t ha-1) at least Tk. 556 billion could be earned from the additional production annually by narrowing 40 % the yield gap. SAARC J. Agri., 18(2): 167-180 (2020)

Pigeonpea is cultivated as a major source of protein for poor farmers with reduced yields. The low yield of pigeonpea is due to faulty agro techniques. The present investigation was conducted to see the effect of integrated agro-techniques on growth and growth attributes of pigeonpea and designed with block randomization having eight treatments viz., integrated nutrient management (INM), integrated weed management (IWM), integrated pest management (IPM) and its combos at AICRP experimental farm, College of Agriculture Tripura. Growth and yield attributes differed significantly due to integrated agro-techniques with poor weed population in IWM. The net come was highest in INM+IWM+IPM (Rs. 49243.85 and Rs. 47757.63). Results revealed that INM+IWM+IPM yielded higher followed by INM+IWM however each of them was statistically at par throughout the study. Economics led INM+IWM as best treatment than the combination of 3 agro-techniques, where additional price occurred.

Interdisciplinary Practice

Integrated weed management (IWM) is a component of integrated pest management (IPM), which is an interdisciplinary practice involving disciplines such as entomology, nematology, plant pathology, weed science, horticulture, agronomy, ecology, economics, and systems science. Most descriptions of IPM mention three elements: a) multiple tactics (for example, competitive varieties, cultural practices, herbicide usage) used in a compatible manner; b) pest populations maintained below levels that cause economic damage, and c) conservation of environmental quality. Integrated weed management was discussed in 1981 during a Weed Science Society of America (WSSA) Symposium entitled Integrated Weed Management Systems Technology for Crop Production and Protection. Topics presented included modeling weed biology, crop manipulation, biological control, herbicide technology, research needs, teaching approaches, and extension implementation. Our paper was presented as part of a symposium on IWM at the 1990 WSSA meeting. This paper describes some of the research that weed scientists have conducted during the past 40 yr. Topics examined include an introductory review of IPM, trends in several categories of weed research, goals and suggestions stated during the 1981 WSSA Symposium on IWM, IWM accomplishments since about 1981, and the future of IWM as a component of IPM.

Conservation agriculture (CA) based tillage technology permits direct seeding through the moderate level of crop residue. CIMMYT introduced this technology in the farmers’ field of Bangladesh for wheat crop in collaboration with Wheat Research Centre, Bangladesh Agricultural Research Institute (BARI). Farmers accept CA based tillage technologies considering the advantages of higher yields, reduced cost of tillage operation, and minimum turn around time between the crops. Up land crops are more suitable under these tillage technologies. Weed management in rice cultivation is not yet in a good shape. Most of the tillage implements are operated by imported Chinese two wheel tractor (power tiller). There are few four wheel tractor CA implement using in research farm. Local manufacturers are being fabricated these cost effective small minimum tillage seed drill, raised bed planter, zero till drill, and strip till drills efficiently in different districts of Bangladesh. Farmers accept CA technologies in their field, especially raised bed planting and minimum tillage technology. There are about 425 numbers of raised bed planters and 865 minimum tillage seed drill in the country. Area coverage under bed planting and minimum tillage system are 5764 ha and 21850 ha, respectively. There are 20125 numbers of farmers involved in raised bed farming. There is a big prospect accelerating the CA based tillage technology in the farmers’ field as irrigation water availability becoming limited or more costly. Mind set up is the big issue for adopting CA tillage technology. Training and multi disciplinary approaches can push forward these tillage technologies ahead.Bangladesh J. Agril.

The Impact

Sesame is one of the important oilseed crops in India. The major constraint of its low productivity is non-adoption of improved technologies by the farmers. Cluster Frontline demonstrations to highlight the impact of different improved technologies like method of sowing, nutrient management, weed management and adoption of whole package of practices of improved technologies for the crop were conducted at 125 farmers' fields during Kharif 2017 and 2020 under rainfed conditions. The improved technologies improved the yield attributing traits as well as seed yield of the crop. The improved technology recorded a mean yield of 476 kg/ha which was 44.68% higher than that obtained with farmer's practice yield of 329 kg/ha. Higher mean net returns of 33,363/ha with a benefit: cost ratio of 3.28 was obtained with improved technologies in comparison to farmer's practice (mean net returns of 18,222/ha and benefit: cost ratio of 2.25).
