Plants species require macro and micro nutrients to complete the growth cycles such as photosynthesis, enzyme activities and secondary metabolite production. The objective of the present study was to investigate the effects of salinity on biomass as well as macro and micro nutrients uptake in the medicinal plant of Andrographis paniculata (AP). In this regard, a split plot experiment was carrie...

A pot culture experiment was conducted at the Department of Agronomy, Madras Veterinary College, Tamil Nadu and Animal Sciences University, Chennai, to study effect irrigation water nutrients on yield nutrient uptake fodder cowpea. The consisted two factors with three four treatments respectively. results indicated that application sewage along recommended dose farm yard manure inorganic enhanc...

Streams control the timing and delivery of fluvial nutrient export from watersheds, and hydraulic processes such as transient storage may affect nutrient uptake and transformation. Although we expect that hydraulic processes that retain water will increase nutrient uptake, the relationship between transient storage and nutrient uptake is not clear. To examine this relationship, we injected a co...

In higher plants, roots acquire water and soil nutrients and transport them upward to their aerial parts. These functions are closely related to their anatomical structure; water and nutrients entering the root first move radially through several concentric layers of the epidermis, cortex, and endodermis before entering the central cylinder. The endodermis is the innermost cortical cell layer t...

During the 20(th) century, seawater temperatures have significantly increased, leading to profound alterations in biogeochemical cycles and ecosystem processes. Elevated temperatures have also caused massive bleaching (symbiont/pigment loss) of autotrophic symbioses, such as in coral-dinoflagellate association. As symbionts provide most nutrients to the host, their expulsion during bleaching in...

Arbuscular mycorrhizal (AM) fungi play an essential role for the nutrient uptake of the majority of land plants, including many important crop species. The extraradical mycelium of the fungus takes up nutrients from the soil, transfers these nutrients to the intraradical mycelium within the host root, and exchanges the nutrients against carbon from the host across a specialized plant-fungal int...

The effects of elevated CO2 on nutrient cycling and selected belowground processes in the closed-canopy sweetgum plantation were assessed as part of a free-air CO2 enrichment (FACE) experiment at Oak Ridge, Tennessee. We hypothesized that nitrogen (N) constraints to growth response to elevated CO2 would be mitigated primarily by reduced tissue concentrations (resulting in increased biomass prod...

Mangrove forests dominate the world's tropical and subtropical coastlines. Similar to other plant communities, nutrient availability is one of the major factors influencing mangrove forest structure and productivity. Many mangrove soils have extremely low nutrient availability, although nutrient availability can vary greatly among and within mangrove forests. Nutrient-conserving processes in ma...

Understanding the physiological processes associated with high yield traits in modern cropvarieties is essential to further increase grain yield and improve nutrient management strategies.Field trials were conducted to study the effects of fertilization and variety on the grain yield ofrice (Oryza sativa L.) with two fertilizer levels and 18 modern varieties. The objectives were toevaluate yiel...
