For actual needs of increasing crop production and quality in modern agriculture, fertigation is an established approach to implement advanced control schemes. The basic idea of this strategy is to maintain the concentration of specific ions in the recirculated drainage water at a desired level for optimal global function. In this way, nutrients which are uptaken by the plants must be refilled,...

Nothofagus pumilio (lenga) forests form monocultures from sea level to timberline in Tierra de Fuego, Argentina. Past studies suggested that the life form change from erect forest to krummholz had advantages to forest function. Aboveground net primary productivity (NPP) and organic matter production per unit leaf area and growing season day were higher in krummholz than in adjacent short erect ...

UV radiation plays an important role not only in plant growth and development but also the accumulation of essential nutrients health-promoting phytochemicals plants. The main objective this study was to examine effects supplemental UV-A, UV-B, UV-AB on nutritional quality lettuce (Lactuca sativa, cv. red leaf “New Red Fire” green “Two Star”) tomato (Solanum lycopersicum L., BHN-589) grown a gr...

The availability of water and nutrients are determining factors for the growth productivity cucumber crop. implementation grafting techniques increases efficiency in absorption resources such as nutrients, improving quality, mineral content, enzymatic activity fruit. objective this research work was to evaluate effect anchor point (soil substrate), graft (with without graft), irrigation volume ...

Excessive nitrogen and insufficient calcium could significantly impact peanut yields. This study investigated the effects of fertilizers on nutrient absorption, utilization, yield; experiments were conducted using cultivar from Xianghua 2008 in a split-plot arrangement with two fertilizer levels (Ca0: 0 Ca1: 568 kg CaO ha−1) main plots six gradients (N0: 0, N45.0: 45.0, N90.0: 90.0, N112.5: 112...

Sorghum is an off-season crop option in succession to soybean the Cerrado region, but many producers underestimate fertilization requirement, which can harm productive performance of system as a whole. Aiming quantify uptake and export nutrients by grain sorghum, experiments were carried out monocropping intercropping with ruzigrass (Uroclhoa ruziziensis), three levels NPK (control without fert...

Arbuscular mycorrhizal fungi (AMF) symbiosis has been shown to improve the ability obtain nutrients and resist adverse environmental conditions. However, there are few studies on functions of AMF in absorption accumulation boron (B). Moreover, it is still unclear whether root colonization rates limited by B deficiency. In this study, Camellia oleifera seedlings were planted normal boron-deficie...

There is no information available on the effect of fuzzless seed trait on cottonseed nutrient composition (minerals, N, S, protein, and oil) under drought stress. The objective of this research was to investigate the effect of the fuzzless seed trait on cottonseed nutrients using five sets of near-isogenic lines (NILs). Each set consists of two lines that share the same genetic background, but ...

Natural variation in the regulation of the accumulation of mineral nutrients and trace elements in plant tissues is crucial to plant metabolism, development, and survival across different habitats. Studies of the genetic basis of natural variation in nutrient metabolism have been facilitated by the development of ionomics. Ionomics is a functional genomic approach for the identification of the ...

Manganese (Mn) in acidic paddy soil has large potential emigrating from the and pollute adjacent ecosystems. Single microorganisms modulate biogeochemistry process of Mn via redox reactions, while roles microbial aggregates (e.g. periphytic biofilm) modulating its biogeochemical cycle is poorly constrained. Here we collected a series biofilms fields China to explore how biofilm regulates behavi...
