The herbicide of acetochlor has been widely applied to control weeds in agricultural sector, but it is responsible for numerous environmental hazards. In the current study, we investigated the effects of the herbicide on bacteria and microfungi communities in soil.

The allelopathic potential of S. oleraceus was assessed using the S. oleraceus-infested soil collected from its dominating communities and its root exudates trapped using living S. oleraceus, while its competitive ability was assessed in greenhouse in an additive design with ratio 1:1 at different densities.

The Present study was carried out at Bharatpur district of Eastern Rajasthan during 2015- 16, 2016-17 and 2017-18. Potato is one of the most important vegetable crops of the country. The development of the Agriculture is primarily depends on the application of the scientific technologies by making the best use of available resources. One of the major constraints of traditional potato farming is low productivity due to non management of weeds. To increase the production, productivity and quality of agricultural produce, on farm testing are being conducted at various farmers’ field.

The degradation of soil wellbeing is one of the most important predicaments to the farming community. There are several reasons for the loss of soil health. One among such issue is uncontrolled use of chemical fertilizers in agriculture ultimately worsen physical, chemical and biological properties of soil. Consequently, alternate solutions to overcome soil degradation, especially agricultural land, the natural way of farming came into existence. The concept of organic farming is mainly to utilize biofertilizers, farmyard manure, compost, vermicompost, green manuring, panchakavya, etc.

In this paper, a new hybrid algorithm was proposed to solve the global optimization problems that combine the invasive weed optimization algorithm with the chicken swarm optimization algorithm. The invasive weed optimization (IWO) algorithm is a stochastic algorithm inspired by the colonial behavior of weeds that was first proposed in 2006 by Mehrabian and Lucas.

Deserts comprise about 95% of the total land surface of Egypt; therefore, their potential for production must be assessed. Weed communities are mainly affected by the environment, and studies may increase our knowledge of the relationship among the weed flora, soil properties, crop rotation, soil management, fertiliser usage, and weed control.

The scope of this book is to demonstrate that we do have an ecosystem theory that can be used to describe ecosystem structure and function. It was previously shown in the book, Integration of Ecosystem Theories: A Pattern (3rd edition, 2002), that the various contributions to systems ecology are consistent and together form a pattern of ecological processes. My book with Yuri Svirezhev, Toward a Thermodynamic Theory of Ecosystems (2004), presented the thermodynamics of this pattern in a mathematical language....

Our goal in writing this book was to describe why weeds occur where they do. We have made no attempt to discuss their management and control: there are excellent texts available for that. Rather, we think that students should understand how and why weeds fit into their environment. This text presents ecological principles as they relate to weeds. Ecology is central to our understanding of how and why weeds invade and yet there are few books that make this connection. That is the niche we hope to fill.
