Field experiments were conducted during the 2010 and 2011 cropping seasons to investigate the effect of farmyard manure and weeding regimes on the growth and yield of okra. The study was a factorial experiment laid out in split plot design, replicated three times. Farm yard manure was assigned as main plot treatments, while weeding regimes was assigned as sub plot treatments. Parameters measure...

in order to compare of ecological management of weed control on economical income, yield and yield components of cotton (gossypium hirsutum l.), a randomized complete block design with 12 treatments and four replications was conducted in mahvelat of khorasan razavi province, iran. treatments consisted of weeding, harrowing, burning, two times weeding, weeding + harrowing, weeding + burning, har...

The study was conducted at the Bangladesh Rice Research Institute Regional Station, Comilla, during three rice growing seasons. The experiment consists of six weeding treatments with three replications. The objective of the experiment was to determine an economic weeding method as well as to improve water management practices of paddy rice. The study indicates that the continuous ponding (100±1...

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh to assess the effect of weeding on growth, yield and yield contributing characters of mungbean (Vigna radiata L.) cv. BINA mung4 during October 2011 to February 2012. The experiment was laid out in a randomized complete block design with four replications. The trial comprised seven tre...

A field experiment was conducted during the seasons of 2010/2011 in a semiarid savannah zone, at the faculty of agriculture demonstration farm University of Zalingei two kilometers east of Zalingei town Western Darfur State. The aim of the experiment is to study the effect of weed control on growth and seed production of (Clitoria ternatea) under rainfed conditions. Four treatments viz.; No wee...

We studied the effects of hand weeding of second-year plants of the biennial garlic mustard (Alliaria petiolata) on first-year plants (seedlings) and native ground layer vegetation. Garlic mustard is a Eurasian species that has invaded deciduous forest ground layers in eastern North America. Treatments consisted of a control and an early or late weeding of second-year garlic mustard. The early ...

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 order to comparison of weeds mechanical control for sugar beet, a rotary cultivator was designed and constructed in first year, and compared with other mechanical control in second year. five treatments, included: rotary hoe cultivator, furrower cultivator, rotary cultivator, no weeding and manual weeding were compared. experiment design was random complete blocks design (rcbd) with three re...

The present study evaluated the effects of different dosages herbicides Oxyfluorfen and Trifluralin on crop properties of garlic, including plant height, number of cloves per bulbs as well as economical and biological yield of garlic. In this research, a randomized complete block design, with seven treatments and three replications, along with a control sample (weeding and no weed control), was...
