after the soviet union dissolution, a chaotic period was begun in the russia. russia lost its glory and felt disgrace. the first group of elites came to power under yeltsin; they tried to re-define russia’s identity as a european country and build a foreign policy on this baseline. therefore russia tried to become closer with the west especially with the u.s. according to their view the sovie...
This paper discusses the potential benefits from shade management in agroforestry systems for taro cropping. Trial work to evaluate weed growth, taro production, and cultivar responses to shade levels are reviewed. It is concluded that weed growth can be reduced in tree-shaded plots without reducing corm production. Higher crop biomass is obtained when taro is grown under fifty percent shade co...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
Peanut (Arachis hypogaea L.) yield and financial return can be negatively affected by weeds the combination of early leaf spot disease [ Passalora arachidicola (Hori) U. Braun] late Nothopassalora personata (Berk. & M.A. Curtis) Braun, C. Nakash., Videira Crous] in Ghana. Research was conducted southern Ghana to evaluate hand-weeding, herbicide applied preemergence (PRE) or postemergence (P...

A field experiment was conducted to find out the impact of weeding regime on performance three Aus rice. The experimental treatment consisted varieties rice viz. BRRI dhan28, Bere Ratna and Kajol Lata, four regimes no weeding, one hand at 35 days after sowing (DAS), two weedings 20 DAS 20, 50 DAS. laid in a factorial randomized complete block design with replications. Eleven weed species belong...
There is interest in the identification of the best seeding density for new corn hybrids and on reduced use of herbicides for weed control. The objective of this study was to evaluate the effects of seeding density (30, 50, 70, and 90 thousand plants ha) and weed control on green ear yield and grain yield in corn cultivar AG 1051. A completely randomized block design was adopted with split-plot...
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...
One factor limiting the achievement of high yields in soybean crop is weed interference. The level interference can vary according to specificities community but also due agronomic characteristics varieties. objective this work was evaluate effects on varieties different relative maturity groups (RMG). A field experiment implemented a randomized complete block design, 3 × 4 factorial scheme, wi...
