Plastic film mulching (PM) has been widely used to improve maize (Zea mays L.) yields and water use efficiency (WUE) in Northeast China, but the effects of PM in a changing climate characterized by highly variable precipitation are not well understood. Six site-year field experiments were conducted in the dry and rainy years to investigate the effects of PM on maize growth, grain yield, and WUE...

A field experiment was conducted at Bangladesh Agricultural Research Institute, Gazipur during rabi (winter) season of 2008-09 to observe the efficacy of two herbicides on the yield of lentil (BARI masur-5). Paraxon, Whipsuper, Ronstar and Topstar were the herbicidal treatments applied after sowing of seeds and two leaf stage of weeds according to their mode of action. Dry weight of weed sample...

breeding based on selection indices is an effective method for improving complex traits such as yield. to assess the efficiency of different selection methods, 50 genotypes of tall fescue (festuca arundinace) were evaluated under two moisture conditions including full irrigation (normal environment) and deficit irrigation (stress environment). the experiment was conducted according to a randomi...

in order to select and release of nassim, a new cultivar of red clover, the researcher carried out the researches at the field of seed and plant improvement institute (spii) in karaj and some research stations such as shahrekord, sanandej, kermanshah, arak, gorgan during years 1996-2006. the experimental research was carried out design rcbd with six treatments and four replications during years...

OBJECTIVE Different dry-aging methods [traditional dry-aging (TD), simplified dry-aging (SD), and SD in an aging bag (SDB)] were compared to investigate the possible use of SD and/or SDB in practical situations. METHODS Sirloins from 48 Hanwoo cows were frozen (Control, 2 days postmortem) or dry-aged for 28 days using the different aging methods and analyzed for chemical composition, total ae...

in order to evaluate quantity and quality hairy vetch (vicia villosa l.) yield in the pure and mixed cropping with barley (hordeum vulgare l.) and triticale (triticosecale) the experiment was conducted at agricultural research station (khodabande) under dryland conditions during 2006 -2008. field experiments were arranged in a randomized complete blocks design with 9 treatments in four replicat...

The primary objectives of this research were to determine the dry period lengths that maximize production across adjacent lactations and also dry period length that maximizes lifetime yield. Effect of days dry (DD) after lactations 1 through 3 were determined separately for both adjacent lactation sums and lifetime yield. Field data, collected through the Dairy Herd Improvement Association, on ...
