Nitrogen and phosphorus uptake, translocation, and utilization efficiency of wheat in relation to environment, and cultivar yield and protein levels. . Phosphorus Response in Wheat Production (Interim Report) Purpose: Wheat is known as a crop that has an extremely high demand for phosphorus in the early growth stages. A healthy wheat crop takes up 15 lbs/ac of phosphorus (P 20 5 equivalent) in the first 30 days . Nineteen NP experiments were carried out with wheat and barley mostly in the Mesaoria plain of Cyprus over the period – The fields were fallowed over the season preceding the experiments. Rainfall ranged from 68 to mm. Kyperounda, a tall durum wheat, Pi a semi-dwarf aestivum wheat, and Athenais barley were the test by:

Hasnuri Mat Hassan Soils School of Agriculture Food and Wine, The University of Adelaide. March, The effect of soil temperature and soil water suction on the rate of phosphorus uptake and growth rate of wheat (Triticum aestivum VILL., Host) was studied.
Plants were grown in perlite slabs separated from an osmotic solution by a semi-permeable : Mohammad Fazilat. Introduction. With respect to the interrelation between soil–plant and environment systems, nutrient uptake by plant roots is one of the most fundamental processes in soil science (Roose and Fowler, ).Phosphorus (P), an essential nutrient for plant growth and productivity, is recognized as the major contributor to the environmental pollution of surface water (Pote et al., ).Cited by: 5.
Phosphorus uptake by wheat grain with three year old plantation was almost similar up to a distance of 9 m and relatively lower than control which varied between and kg ha −1. But with three year old plantations higher uptake was recorded between 3 and 15 m distance than control ( kg ha −1) which varied between and kg Cited by: 7.
The apparent contribution of mass flow to plant uptake of nutrients between mid- April and mid-June was greater than the measured plant uptake for sodium, calcium, magnesium and sulphur (14, 9, 2 and 4 times respectively); however, only 50 % of the measured plant uptake of nitrogen and potassium and 5% of the phosphorus was supplied in this by: Fertilizer application significantly enhanced growth, yield and nutrient uptake traits of wheat.
Application of NPK kg ha-1 to TD-1 recorded maximum tillers, spike length, grains spike-1, biological yield, grain yield, harvest index, dry matter, leaf area index, crop growth rate and NPK uptake.

It is a component of nucleic acids, so it plays a vital role in plant reproduction, of which grain production is an important result.
It is also critical in. New Phytol. ;(3) Arbuscular mycorrhizal fungi contribute to phosphorus uptake by wheat grown in a phosphorus-fixing soil even in the absence of positive growth by: Nutrient uptake and growth, and hence the model parameters that encapsulate these processes, may vary with light and temperature.
Uptake of a nutrient, particularly those that are frequently growth-limiting, like phosphorus, is usually counter to its free-energy gradient between the inside and the.
First published in Nutrition is a major environmental factor in regulating plant growth, and is therefore of significant practical concern to agriculturalists and ecologists. In order to achieve efficient plant production, it is essential to gain a full understanding of the basic principles underlying the three-way interaction between the plant, its nutrition and its environment.5/5(1).
The Feekes 7 growth stage identified as the optimum growth stage for foliar P application is also the stage in which N is applied to avoid yield loss. Consequently, this allows reduction of cost associated with separate application.
Research on improving uptake of P by wheat leaves needs to be further studied. Nevertheless, growth increases of AM plants over NM counterparts are maintained if high total soil P is poorly available (Bolan, ).
Recent physiological and molecular research has revealed clearly that the AM pathway plays a major role in P uptake, regardless of the extent to which an AM plant benefits in terms of increased growth or P uptake.
The maximum phosphorus uptake of kg/ha were recorded at harvest with the application of 75 kg phosphorus/ha. The same way K uptake was also observed to increase with increase in level of fertilizer, plant population and organic manure application.

Keywords: Phosphorus, Fertilizer, Cowpea, Growth, Yield, Umudike. Introduction Cowpea (Vigna unguiculata (L.) Walp) is an important grain legume. Phosphorus is a key Nutrient for plant growth and development. Phosphorus is taken up from the soil solution by plant roots as orthophosphate ions, principally as monovalent orthophosphate, H2PO4 − ions.
This study was conducted to explore the role of different phosphorus (P) levels and P uptake and use efficiency on acidic soils. The soil was collected from the acidic region of Bangladesh Cited by: 2. Phosphorus and Cannabis Columns - Biology Brief So let’s look at the physiological function of phosphorus, its interactions with other nutrients in growth media, higher levels of magnesium are believed to increase the rate of phosphorus uptake because magnesium is an integral part of the phosphorus-uptake system.
Nitrogen, phosphorus and potash content and uptake by grain and straw of wheat were also found higher in same treatment. The application of kg N/ha was register significantly the highest all the growth and yield contributing character, including the grain and straw yields as well as net return of : K.
Shah, B. Tandel, G. Bhimani. The rate of P and K uptake peaked between stem elongation and the beginning of heading in Montana (steepest slope in curves on Figures 2b and c).
In Saskatchewan, the uptake rate of P and K was consistently high from tillering to stem elongation (Figure 3b). 3 Cumulative Nutrient Uptake (percent of maximum) Plant Growth Stage FIGURE : Clain Jones, Kathrin Olson-Rutz.
Phosphorus uptake by winter wheat cultivars as related to root characteristics Public Deposited. The cultivars were grown in a growth chamber with a 16 hour light period at 22° C and an 8 hour darkness at 16° C for approximately three weeks.

Phosphorus (P) is one of the most vital nutrient needed for crop production. Phosphorus plays an important role in root growth and builds resistance against abiotic stresses. In the current study two wheat cultivars (phosphorus responsive) were planted to study the treatment effects in polythene bags.
The treatments were 5 different levels of P (P0 = g/bag, P60 = g/bag, P80 = g Author: Mukhtar Ahmed, Sehrish Khan, Muhammad Irfan, MuhammadAqeel Aslam, Ghulam Shabbir, Shakeel Ahmad. critical to meet corn nutritional needs. Alternatively, uptake of N, K, Mg, Mn, B, and Fe favored early-season uptake during vegetative growth.
Further analysis identified possible relationships between nutrient uptake and removal with hybrid background and transgenic insect protection.

In the northwest, N uptake was also excessive both in winter and spring wheat. In the MLYR region,File Size: KB. A study was conducted to observe the direct and residual effects of phosphate rock (PR) on the growth and yield of wheat (n) during rabi season of under Old Himalayan Piedmont Plain (AEZ 1) soil at Wheat Research Sub-center, Dinazpur.
The experiment was designed with four treatments and laid out in a Randomized Complete Block Design (RCBD) with four replications of each. Induced phosphorus deficiency in seedlings can occur in very dry conditions, but is often transitory and plants recover when the topsoil rewets.
Symptoms of phosphorus deficiency in wheat are usually non-specific and difficult to diagnose in the field. The most noticeable feature of phosphorus deficiency in wheat is reduced growth and vigour.
Wheat is a grass widely cultivated for its seed, a cereal grain which is a worldwide staple food. The many species of wheat together make up the genus Triticum; the most widely grown is common wheat (T.
aestivum).The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around BCE. Botanically, the wheat kernel is a type of fruit called a Clade: Tracheophytes.
The guidelines for Maximum Economic Yield - Spring Wheat Production suggests split applications of nitrogen as follows: 40% pre-plant, 10% in starter, 25% at tillering (Zadoks Growth Stage ) and 25% at stem elongation (Zadoks Growth stage ). An additional nitrogen application of about kg/ha ( lb/ac) swollen boot (Zadoks.
A significant increase in P uptake by wheat plant was also obtained due to different treatment (Table 1).T3 treatment showed the maximum P uptake ( kg ha-1) and control treatment showed the minimum P uptake ( kg ha-1).P applied in the form of TSP was found to have better effect over PR having same rate of P application (26 kg P ha-1).

Wheat growth and nutrient uptake by phosphate solubilisers 16 Their P solubilisation was compared with their parents. The solubilised P-was determined in clear filtrate using Ascorbic acid method (Watanabe and Olsen, ). The intensity of blue colour was measured.
Production of phosphorus efficient crop cultivars can increase food productivity and decrease environmental pollution. Categorization of existing germplasm is a prerequisite to develop P efficient crop cultivars.
For first experiment, 30 wheat genotypes were grown in hydroponics with two P levels (i.e., deficit, 20 μm KH2PO4 and adequate, μm KH2PO4).Cited by: 3. That synergism appears to be principally driven by nitrogen-induced uptake of phosphorus.
Magnesium has also been widely reported to have a synergistic relationship with phosphorus; higher levels of magnesium are believed to increase the rate of phosphorus uptake because magnesium is an integral part of the phosphorus-uptake system.
Fertilizer use and management is of crucial importance in irrigated production systems of Pakistan to achieve high yield, which leads to an extensive removal of essential nutrients.
Three wheat varieties (TD-1, T.J and Mehran) were treated with nine levels of fertilizer (, and NPK kg ha-1) were set Cited by: Continuous cropping of rice (Oryza sativa L.) and wheat (Triticum aestivum L.) deplete soil fertility and crop strategy to increase crop productivity under rice–wheat system is balanced application of crop nutrients.
Field experiment was conducted to assess the impact of phosphorus (0, 40, 80, kg P ha −1) and zinc (0, 5, 10, 15 kg Zn ha −1) on the productivity of Cited by: 7. Free-living plant growth-promoting rhizobacteria (PGPR) have favourable effect on plant growth, tolerance against stresses and are considered as a promising alternative to inorganic fertilizer for promoting plant growth, yield and quality.
PGPR colonize at the plant root, increase germination rates, promote root growth, yield, leaf area, chlorophyll content, nitrogen content, protein content Cited by: 5.The plant still takes up some N but the rate slows and this phase is characterized primarily by a redistribution of N within the plant.
As the grain forms, N is translocated from the leaves and stems to the developing grain. Figure 1.
