Heading toward the roundhouse after dark, I heard the powerful sound of people playing hosho (large maraca-like shakers) from some distance down the path. As I entered the dimly lit kitchen hut where the ceremony was being held, I could make out people clapping, singing, talking, and drinking; one frail old woman was dancing by herself in the center of the room. Beneath all of this there was st...
Weeding or deselection of materials has become an integral part of library management. Based on a nineteen-question survey about weeding practices in public libraries, this article discusses the personal perspectives of public librarians on weeding as well as the weeding practices of their institutions. The three most common criteria for weeding are circulation, physical condition, and accuracy...
in order to investigate chemical control of weeds in nursery of orange coneflower and moss rose two experiments were conducted in randomized complete block design (rcbd) with four replications in 2011. treatments were per-plant trifluralin (ec48 percent) with and without incorporation with soil at 0.2 and 0.3 ml/m2, per-emergence and post-emergence oxyfluorfen (ec24 percent) at 0.2 and 0.3 ml/m...
The field experiment was carried out during the summer season of 2021-2022 to study response different weed management practices on growth and yield black gram. Cyperus sp., Phyllanthus niruri, Trianthema portulacastrum, Amaranthus viridis were dominant weeds. It observed that besides free treatment lowest count, dry weight weeds (3.66 g m-2), index (2.73%) as well highest control efficiency (6...
Reduction of herbicide consumption is one of the goals of modern agriculture. Intercropping is an option to reduce growth and reproductive potential of weeds while maintaining agricultural system productivity. The objective of this study was to evaluate the effects of bean and maize intercropping on weed control, economical yield of system and land use efficiency. Experiment was done at the Res...
Legume cover crops have previously been evaluated for green manure, weed control and soil moisture conservation, this study includes further evaluation of biomass the legume fodder. Our research was to compare nutrients concentration at different times in treatment plots coffee plantation after establishment a desmodium crop with quantification resulting as fodder livestock. This case conducted...
Field experiments were conducted during 2017 and 2018 to evaluate the efficacy of herbicides NICOSULFURON and EPTC alone or in combination with seed priming on weed control and corn yield. NICOSULFURON (80 g a.i. ha‒1) was applied at four- to six-leaf stage of corn as post-emergence and EPTC (4920 g a.i. ha‒1) applied as pre-plant incorporation (PPI). Among the herbicide treatments, the lowest ...

Conventional methods of weed control are weather dependent, costly and labour intensive. Indiscriminate use of chemicals for controlling weeds may pose environmental problems. Sorghum allelopathy is a new technique, which has been tested for controlling weeds of wheat (Triticum aestivum L.) as a substitute for chemical herbicides to reduce environmental pollution. Mature sorghum herbage contain...
in this study, the effects of weed control treatments and plant density on lentil (lens culinaris) yield and yield components as well as weed control efficacy were investigated. the study was conducted according to a split-plot arrangement based on randomized completely block design in three replicates in karaj in 2007-2008. the weed control chemical treatments in four levels (trifluralin herbi...
