Alfalfa (Medicago sativa L.) is an important forage legume in farming and animal husbandry systems. This study assessed the effects of arbuscular mycorrhizal fungi (AMF) phosphate-solubilizing bacteria (PSB) on alfalfa growth under different phosphorus application levels. In this experiment, a complete randomized block design was used. The following four bacterial applications were used: inoculation Funneliformis mosseae (Fm), Bacillus megaterium (Bm), mixed species (Fm × Bm) noninoculation...

The deficiency of nitrogen and phosphorus is a primary constraint on the normal growth alfalfa (Medicago Sativa L.) in alkaline desert soils northern Xinjiang. Optimizing combination fertilizers can maximally significantly enhance farmers' economic returns while concurrently mitigate soil environmental pollution. For this purpose, field experiment based randomized complete block design was conducted over two consecutive years (2019 2020) Shihezi, Xinjiang province, China. WL366HQ variety...

Soil organic carbon (SOC) is the principal factor contributing to enhanced soil fertility and also functions as major sink within terrestrial ecosystems. Applying fertilizer a crucial agricultural practice that enhances SOC promotes crop yields. Nevertheless, response of SOC, active fraction hay yield nitrogen phosphorus application still unclear. The objective this study was investigate impact nitrogen-phosphorus interactions on fractions in alfalfa fields. A two-factor randomized group...

Abstract Alfalfa ( Medicago sativa L.) is an important forage legume in arid areas, but limited water resources and low fertilizer utilization have restricted its agricultural development. Meanwhile, studies on the effects of integrated phosphorus production performance water‐use efficiency phosphorus‐use alfalfa, especially hay yield, accumulation, total uptake are rarely reported under drip irrigation. The treatments were a factorial combination three irrigation rates (5,250, 6,000, 6,750...

The productivity of alfalfa is associated with a large amount nitrogen (N) and phosphorus (P); the addition exogenous N P fertilizers can fully exploit growth potential alfalfa. However, there uncertainty about relationship between changes in photosynthetic physiology anatomy. We conducted field fertilization experiments on second third years under drip irrigation, as well measurement physiology, anatomical structure agronomic traits at different levels (0, 120 kg·ha−1) P2O5 50, 100 150...

Abstract Appropriate fertilization is an important management practice for optimizing the nutritional quality and increasing phosphorus use efficiency (PUE) of field‐grown alfalfa ( Medicago sativa L.). A 2‐yr field experiment in 2017 2018 Xinjiang, China, involving with different amounts N (0, 105, 210 kg ha −1 , referred to as 0 1 2 respectively) P 50, 100, 150 3 was established resulted production high‐quality under drip irrigation. The crude protein (CP) content treatment greater than...

Abstract Rational water and fertiliser management have an important impact on alfalfa production. This research aimed to explore the effects of phosphorus (P) water‐use efficiency (WUE) phosphorus‐recovery (PRE) each cut under drip irrigation determine optimal interaction ratio improve quality yield alfalfa. Different levels were set, i.e., 5250, 6000 6750 m 3 /ha (referred as W 1 , 2 respectively), P (0, 50, 100 150 kg/ha O 5 referred 0 respectively) set hay nutrient irrigation. The...

Nitrogen (N) and phosphorus (P) fertilizers change the morphological structure effectiveness of P in soil, which turn affects crop growth, yield, quality. However, effects mechanism combined N application on content fractions transformation effective forms alfalfa ( Medicago sativa L.) production is unclear. This experiment was conducted with four levels N: 0 (N ), 60 1 120 2 ) 180 kg·ha -1 3 ); two (P O 5 ): 100 ). The results indicated that, under same level, significantly increased soil...

Soil salinity and poor soil structure are the main limitations of agricultural economy in arid areas.The objectives this study were to investigate effects different potassium humate amounts on cotton growth, seed yield, water use efficiency under film-mulched drip irrigation with brackish water.The results showed affected salt accumulation rate treatments (2.5, 5, 10, 15, 20, 30 kg•ha -1 ) within 0-40 cm depths was 63.0%, 67.9%, 68.9%, 70.5%, 75.4%, 100% lower than untreated soils.Potassium...

Alfalfa productivity and cold resistance in different regions are influenced by the fall-dormancy level of alfalfa. However, it is unclear whether stoichiometric characteristics nutrient resorption efficiency alfalfa leaves also vary with level. In order to further understand differences absorption requirements fall-dormant alfalfa, we conducted field trials on 30 cultivars for 2 consecutive years 2020 2021. We investigated concentrations carbon, nitrogen, phosphorus mature senescent leaves;...

Abstract Rational water and fertilizer management have an important impact on alfalfa production. This research aimed to explore the effects of phosphorus (P) hay yield, nutrient quality, water-use efficiency (WUE) phosphorus-recovery (PRE) each cut under drip irrigation determine best P interaction model for high quality yield alfalfa. In this study, different levels, i.e., 5.25, 6.0, 6.75 ML ha -1 (referred as W 1 , 2 3 respectively), levels (0, 50, 100, 150 kg O 5 referred 0 respectively)...
