Background: Selection for fall dormancy (FD) in alfalfa (Medicago sativa) can impact other traits, including dry matter yield (DMY), winter survival rate (WSR) and nutrient compositions. The current study was aimed to screen varieties with greater yield, good quality strong ability thus are more suitable planting Heilongjiang, China may be similar upper-latitude semiarid environments the world....

Abiotic constraints are a source of concern in agriculture, because they can have a strong impact on plant growth and development, thereby affecting crop yield. The response of plants to abiotic constraints varies depending on the type of stress, on the species and on the organs. Although many studies have addressed different aspects of the plant response to abiotic stresses, only a handful has...

Abstract The adverse effects of exposure to microcystins in terrestrial crops have been well documented. However, the retention and bioavailability microcystin-LR, one most prevalent cyanotoxins, from soil plants, is poorly understood. In present study, amount free microcystin-LR two types, a silty sand clayey loam, with three toxin concentrations time was investigated. Using on Medicago sativa...

Little is known how the deep root systems of perennial crops contribute to deeper and better resource use when intercropped with annuals in arable fields. Therefore, we aimed at measuring capacity deep-rooted perennials, alfalfa ( Medicago sativa L.) curly dock Rumex crispus access nutrients located under neighboring 1.0 2.5 m soil depth. Alfalfa were able tracer sources 15 N Cs) placed a dista...

Abstract Alfalfa ( Medicago sativa L.) is the most widely planted forage, which have higer economically valuable and better ecological benefits in world. However, it’s sensitive to high root-zone temperature tropical subtropical areas. In order explore changes of metabolites alfalfa under heat stress, study applied unique landrace ‘Deqin’ explored mechanisms on basis pseudotargeted metabolomics...

Stem cellulose and lignin concentrations are major determining factors of alfalfa (Medicago sativa ssp. sativa L.) forage quality. Only limited information is available on the genetic variability and the influence of environmental effects on these two stem-quality traits. Our objectives were to: evaluate the variability for stem cellulose and lignin concentrations in modern alfalfa germplasms a...

OBJECTIVE The objective of this study was to evaluate the effect of sodium diacetate (SDA) on fermentation profile, chemical composition and aerobic stability of alfalfa (Medicago sativa L.) silage. METHODS Fresh alfalfa was ensiled with various concentrations of SDA (0, 3, 5, 7, and 9 g/kg of fresh forage). After 60 days of the ensiling, the samples were collected to examine the fermentative...

Access to livestock manure is increasing in semi-arid cropping systems of U.S. Northwest prompting evaluation fertilization strategies on regional production systems. A study conducted from fall 2012 2019 used: fall- or spring-applied dairy (56 Mg ha−1), fall-applied composted (33 urea SUPERU (Koch Agronomic Services), and a control (n = 6) corn (Zea mays L.)–barley (Hordeum vulgare L.)–alfalfa...

Herbage yield of alfalfa (Medicago sativa L.) depends on forage management or environmental conditions that change C and N resource acquisition, and endogenous plants factors such as root organic reserves and number of active meristems. The aim of this work is to study the influence of two sowing dates in summer (12 July or 9 August), N fertilization (0 or 100 kg ha(-1)) and/or irrigation appli...

Alfalfa (Medicago sativa L. cv. Saranac) seed were soaked for 20 minutes in water, acetone, or methanol containing 10 or 50 mg/ml of oxamyl (Vydate L) or coated with a 2% aqueous cellulose solution containing the same amounts of oxamyl. Seed were analyzed for oxamyl by HPLC immediately after treatment and after 9 and 26 months of storage. Oxamyl content of alfalfa seed did not decline after 26 ...
