in order to study the sowing system, row distance and weeding effect on yield and yield components of intercropped maize with peanut, this experiment was conducted, as factorial based on a rcbd with three replications at the research farm of agriculture center of zabol university (iran) during growing season 2011- 2012. sowing system were four levels including sole maize, sole peanut, 50% maize...

Weed control is necessary to ensure a high crop yield with good quality. Herbicide application and mechanical weeding are the most common methods worldwide. The use of herbicides has led increasing occurrence herbicide-resistant weeds unwanted contamination environment. Mechanical weed harms beneficial organisms, increases degradation organic matter, may dry out soil, stimulate new cohorts seed...

To assess the effect of non chemical management of weed control on forage Sorghum (Sorghum bicolor) a field study was conducted in Varamin, Iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (W1= one time cultivation at 3-leaf stage using a duck foot cultivator, W2<...

In Bangladesh during 2017-2018 was conducted in a farmer's field of the Chattogram hill districts to determine effectiveness different weed control strategies for transplanted chilli. The dry weight weeds, efficiency, index, and yield components like number fruits per plant, fruit length, weight, marketable yield, had been significantly affected by using measures. act treatment chilli fields, h...

The concepts of relative velocity and acceleration, deviation velocity and acceleration and relative momentum of point particles in spaces (manifolds), the tangent bundle of which is equipped with a transport along paths, are introduced. If the tangent bundle is endowed also with a metric, it gives rise also to the notion of a relative energy. Certain ties between these quantities are considere...

1. Introduction Analysis of variance is used to test for the real treatment differences. When the null hypothesis that all the treatment means are equal is not rejected, it may seem that no further questions need to be asked. However, in some experimental situations, it may be an oversimplification of the problem. For example, consider an experiment in rice weed control with 15 treatments viz. ...

In this paper, an electro-mechanical integrated weed management system was designed, constructed, and tested. This laboratory-scale solution elements of machine vision, controls, mechanical actuation to selectively remove weeds from within a crop row. The device validated in controlled environment using corn crops. Various conditions were considered ensure the robustness design. Though some des...
