Corn is one of the strategic food commodities in Indonesia which is currently widely used as animal feed ingredient. But the average productivity of national corn is still low. This study aims to determine the dose of herbicide ammonium glufosinate 200 g/L which can maintain the growth potential and yield of corn plants. The experiment was carried out at the Ciparanje Experimental Garden of the Faculty of Agriculture, Padjadjaran University, Jatinangor, Sumedang Regency, West Java, with altitude of 750 meters above sea level in November 2017 to March 2018. The experimental method used was a randomized block design consisting of seven treatments which were repeated four times. The treatments tested consisted of: manual weeding, application of different doses of ammonium glufosinate (450, 600, 750, 900, and 1050 g/ha) and unweeded check. The results of the experiment showed that application of ammonium glufosinate 200 g/L herbicide is able to suppress weed growth in corn cultivation. The application of ammonium glufosinate 200 g/L herbicide starting from a dose of 600 g/ha is effective in suppressing weed growth and suppressing the loss of yield of corn due to the presence of weeds.

Field experiments were conducted on the research farm of Federal University Dutse in the Sudan savannah ecological zone Nigeria to evaluate the performance of upland rice varieties as affected by herbicide and poultry manure application. The two locations lie in the Sudan savanna ecological zone with a mean annual rainfall of 600 mm distributed between May and October. The treatments consisted of three rates of poultry manure (0, 5 and 10 t/ha) and five weed control treatments factorially combined in the main plot while two upland varieties of rice (Nerica and Faro 48) in the sub-plot. The treatments were laid out in a split-plot design with three replications. Application of pendimentaline+one hoe weeding at 6 WAS produced significantly greater plant height, leaf area, leaf area index, length panicle, panicle weight per plant, biological yield and the grain yield of rice than the other rates comparable with the hoe weeded control while the weedy check had the least. The application of 10 t/ha of poultry manure gave significantly greater plant height, leaf area, leaf area index, length of panicle, number of grain per panicle, harvest index and the grain yield of rice than the lowest rates (0 and 5 t/ha). It can be concluded that rice farmers in the sudan savanna zone of Nigeria can adopt 10 t/ha of manure, pendimentaline+one weeding control at 6 weeks after sown and the Faro 48 rice variety since the combination of these treatments gave better weed control, growth and yield of paddy rice.

A field experiments was conducted at Professor Jayashankar Telangana State Agricultural University, Rajendranagar during <em>kharif</em> 2017 for the evaluation of diuron in two different soils. The treatments consisted of diuron 80% WP at 0.5, 0.75 and 1.0 kg ha<sup>-1</sup> along with registered formulation of pendimethalin 38.7% CS at 677 g ha<sup>-1</sup>, intercropping with green manure crop, mechanical weeding thrice at 20, 40, 60 days after sowing and unweeded control. The experiment was carried out in a randomised block design replicated thrice. The weed flora of the experimental field in red soil was dominated by <em>Cynodon dactylon</em>, <em>Rottboellia exaltata, Parthenium hysterophorus,</em> <em>Trianthema portulacastrum</em> and <em>Commelina benghalensis</em>. While in case of black soil predominant flora was <em>Cynodon dactylon, Cyperus rotundus, Parthenium hysterophorus</em>, <em>Euphorbia geniculata</em>, <em>Tridax procumbens</em>, <em>Cyanotis cristata</em>, <em>Digera arvensis</em> and <em>Celosia argentea.</em> The macronutrient contents in cotton crop were higher in polymulch, mechanical weeding thrice at 20, 40 and 60 DAS and this was comparable to pre emergence application diuron at 1.0 kg ha<sup>-1</sup> followed by post emergence application of pyrithiobac sodium + quizalofop <em>p</em> ethyl in red soil and post emergence application diuron at 1.0 kg ha<sup>-1</sup> followed by post emergence application of pyrithiobac sodium + quizalofop p ethyl and diuron at 0.75 kg ha<sup>-1</sup> black soil. The minimum weed competition facilitated higher DMP and nutrient uptake by the plant. The nutrient removal by weeds also was minimal in polymulch, mechanical weeding thrice at 20, 40, 60 DAS, diuron at 1.0 kg ha<sup>-1</sup> pre emergence application of pyrithiobac sodium + quizalofop p ethyl followed by post emergence application of diuron at 0.75 kg ha<sup>-1 </sup>in both red and black soil.

Availability of herbicides inflicts to adopt an integrated use of weed control methods (other than chemical methods) in minor crops. In Pakistan more than 70% farmers have land less than 5 ha, so it is improvident to employ very costly chemical and mechanical weed control methods. At present, the resource conservation technology is widely adopted, so it is a major challenge to develop a sustainable, reliable and integrated weed management system. As in minor crops, sustainable production contributes in agricultural production as well as food security and food supply; therefore, it is important for national economies and human health. Excessive use of herbicides over a long time make leads herbicide resistant weeds. There are some factors including shifting ability of weed population, increase in environmental concerns and increase in cost of management, all these factors made farmers difficult to control resistant weeds within their limited resources. It is proved from previous research that selection of viable seed and the use of different cultural practices maybe conceivable strategy to decrease weed competition. Our focus in this review article is on the utilization of these practices to reduce the competitive ability of weeds, for their proper management in minor crops. Our basic aim of this article is to assist researchers in the design of eco-friendly and economically viable weed management strategies, which will help in reducing the herbicides liability and mechanical cultivation from farmer’s production costs.

A field study was carried out to evaluate the efficacy of Prioxofop-Propanyl 15% WP (Markclodina) herbicide for wider weeds range in wheat crop during Rabi 2015-16. Six treatments including four herbicides treatments <em>viz.</em> Pendimethalin at 1.0 kg/ha, Clodinafop at 0.060 kg/ha, Markclodina at 0.060 kg/ha, Isoproturon + 2, 4-D at 1.0+0.5 kg/ha along with hand weeding twice (30 and 60 DAS) and one weedy check were used. <em>Avena ludoviciana</em> (34.30 %) and <em>Phlaris minor </em>(25.26 %) were the most dominatinggrassy weeds. New test herbicide Markclodino had better efficacy in controlling <em>Phalaris minor</em>,<em> Avena fatua </em>and<em> Lolium </em><em>temulentum</em>as evidencedfrom significantly less number of weeds at all the stages of observations. The highest weed control efficiency (80.5 %) was recorded with post emergence application of Markclodina 0.060 kg/ha at 90 DAS. The application of markclodina at 0.06 kg/ha remaining at par with clodinofop propargyl (market sample) at 0.06 kg/ha, isoproturon + 2,4-D at 1.0 + 0.5 kg/ha produced significantly higher grain yield. The magnitude of increase in yield due to Markclodina over weedy check was 68.9 %. Field demonstrations on the performance of Markclodina under various locations showd that there was maximum 19.7 % increase in grain yield over control at distt. Hamirpur (Himachal Pradesh).

<span>Rice industry in Malaysia faces serious challenges in managing weedy rice (<em>Oryza sativa</em> L.) since it was first observed in 1988. Unfortunately, there is no simple control method for weedy rice. Recommended practices in Malaysia adopted various integrated weedy rice management strategies mainly on land preparation and pre-harvest period controls. Multiple tillage, chemical applications via pre-emergence and pre-sowing herbicide, and manual weeding are the usual weedy rice control practices by majority of Malaysian farmers. The conspecific nature of weedy rice with cultivated rice increased the difficulty to control the weed with several weedy rice biotypes have already mimic the local varieties. Introduction of Clearfield® Rice Production System (CPS) in 2010 has shifted the current weedy rice management strategies to an herbicide-tolerant crop approach. Some concerns of the technology including potential resistant to weedy rice and environmental issues were discussed. Additional weedy rice management strategies as alternative approaches for Malaysia rice agro-ecosystems were proposed in this review to fill the gaps on current weedy rice controls including reducing cross contamination between farms, managing weedy rice seedbank, empowering alternative culture methods in rice farming, strengthening current Clearfield® system, and exploring ‘omics’ research for other potential herbicide tolerant rice. Improvement in communication is proposed to ensure any information on weedy rice management is effectively transferred between farmers and authorities.</span>

A pot experiment was conducted under field conditions in Al-Qizuina district-province of Najaf during the 2017 growing season in order to pre-planting control of field dodder )<em>Cuscuta campestris</em>( by breaking its seed dormancy and reducing seed banks in the soil. The experiment tested 56 treatments (chemical, biological and physical) in a complete randomized design with four replicates. Results showed significant differences between treatments. Gibberelic acid at 800 ppm resulted in the highest germination rates of the dodder seeds (92%), while KNO<sub>3</sub> had the highest speed of seed germination (7.6 days). Some other concentrations of Gibberellic acid, Salicylic acid, Ethrel and KNO<sub>3</sub>, and seed extracts of Maize, Barley and Alfalfa as well as the physical treatment of boiling water had significant effects on the dodder seeds in terms of germination rates which ranged from 19 to 51% and germination speed that ranged from 8.4 to 15.4 days compared to the control treatment which resulted in 0.75% and 20.82 days, respectively. The study confirmed that using high efficient treatments in breaking dormancy and increasing seed germination of dodder as pre-planting measurements can be practically applied in the integrate management of this pest.
