Weed management has become increasingly important in the backdrop of sustainable crop production, uncertain climatic patterns and food security concerns in Pakistan. Due to diverse agro-climatic conditions, 267 weed species have been identified to be responsible for causing monetary loss worth 3 billion USD annually. Weed competition for resources, interference with crops, weed-related increased incidence of pests and diseases in different crops, and high management costs incurred in controlling weeds make weed management a critical task for the farmers.Moreover, herbicide resistant weeds, labor shortage, higher wages, weed population shifts, changing climatic optima, unavailability of proper and timely inputs, ever increasing threats of invasive weeds, lack of knowledge and training regarding herbicides, and the poor financial resources of the small land holders are major hurdles towards effective weed management in Pakistan. These multi-dimensional problems need holistic line of action with multidisciplinary collaboration. Improved knowledge of weed ecology, biology, genetics and molecular biology is essential for developing sustainable weed control practices. Some advances are already commercialized, and others are in the process of development. Advancements like vision guided machines for site-specific weed management, recognition and application modules, development of air inclusion nozzles, nanoherbicides, water based formulations with fewer hydrocarbons, herbicide-resistant transgenic crops, robotics to monitor and spray weeds, decision support systems and predictive modeling can be adopted to foster modern weed management in the country. Various conventional weed management approaches like narrow row spacing, row orientation, increased

“…Chickpea (Cicer arietinum L.) is one of the most important pulses as well as a vegetable crop in Pakistan. It contributes 75 percent to total pulses grown in Pakistan (Sibtain et al, 2015;Abbas et al, 2016). The area under chickpea cultivation in Pakistan during 2012-13 was 992 K ha with a production of 751.3 K tons with an average seed yield of 757 kg ha -1 .…”

Three-year field studies were undertaken at Agricultural Research Institute, Dera Ismail Khan, Khyber Pakhtunkhwa Province, Pakistan from 2010-11 to 2012-2013 with the aim of assessing the efficacy of different management techniques on weed growth and yield of chickpea under rain-fed conditions on residual moisture of a previous rice crop. Treatments of the experiment consisted of recommended full and half doses of three herbicides, i.e., Stomp 330E, Dual Gold 960EC and Isoproturon 500EW and the plant extract of Parthenium hysterophorus. Hand weeding treatment was kept as positive control whereas weedy check was included as negative control treatment. The experiment was laid out in a Completely Randomized Block (CRB) design replicated thrice. Parameters of the investigation were weed density, fresh weed biomass, chickpea growth, biological yield and seed yield. The data revealed that the full dose of Stomp 330E proved superior in terms of weed suppression by giving only 84, 69 and 55 weeds m-2 as compared to weedy check for the years 2010-11, 2011-12 and 2012-13, respectively. Likewise, the highest plant height and seed yield were also recorded for Stomp 330E (full dose) during the entire study, which was statistically at par with hand weeding. However, there was a reduction in overall chickpea yield during the second and third years of experimentation resulting from lower average rainfall. The extract of P. hysterophorus followed Stomp 330E in weed suppression, enhancing plant height as well as biological yield and seed yield. Moreover, the result also shows statistically similar results of the extract of P. hysterophorus for all other tested treatments. Based on the findings of the present research, it was found that herbicides and hand weeding showed superior results in terms of all tested parameters. However, both approaches are non-judicious: hand weeding is laborious while herbicides may cause environmental pollution, hence the herbicidal potential of P. hysterophorus needs to be encouraged in order to achieve sustainable weed management and high yield in an eco-friendly manner.
