characteristics of nutrient accumulation and efficiency in maize under different agronomic managements
a four-year field experiment was conducted to understand the characters of nutrient accumulation and distribution in maize under different yield levels, so as to provide scientific guidance for effective utilization of mineral fertilizers, and eventually for high yield of spring maize. the grain yield, nutrient (nitrogen, phosphorous, potassium) accumulation and uptake efficiency were evaluated...
متن کاملDecomposition and Nutrient Release of Different Cover Crops in Organic Farm Systems
Cover crops act as green manure adding organic matter to agricultural-soils. For legume green manures to be an effective nitrogen (N) source for organic farming systems, their N release must be in synchrony with crop N demand. The objectives of this study were 1) determine the decomposition rates of three common cover crops (white clover, (Trifolium repens,L) red clover (Trifolium pratense L.) ...
متن کاملDecomposition and nutrient release from fresh and dried pine roots under two fertilizer regimes
Root decomposition and nutrient release are typically estimated from dried root tissues; however, it is unlikely that roots dehydrate prior to decomposing. Soil fertility and root diameter may also affect the rate of decomposition.. This study monitored mass loss and nutrient concentrations of dried and fresh roots of two size classes (<2 and 2-5 rnrn) over a 12-month period in fertilized and c...
متن کاملNutrient uptake of peanut genotypes under different water regimes
Drought is a serious environmental stress limiting growth and productivity in peanut and other crops. Nutrient uptake of peanut is reduced under drought condition, which reduces yield. The objectives of this study were to investigate nutrient uptake of peanut genotypes in response to drought and to estimate the relationship between nutrient uptake and peanut yield under different water regi...

گوشت قرمز یکی از مهم ترین فرآورده های دامی در تأمین پروتئین و انرژی می باشد که در حمل ویتامین های محلول در چربی نیز حائز اهمیت می باشد. انسان مانند سایر مهره داران اسید های چرب ضروری (لینولئیک و آلفا لینولنیک) مورد نیاز خود از طریق غذا تأمین می نماید. اسید های چرب ضروی پیش ساز اسید های چرب غیر اشباع با چند پیوند دوگانه هستند. اسید لینولنیک پیش ساز اسیدهای چرب امگا 3 و اسید لینولئیک نیز پیش ساز ...
