Background: Phosphorus is the crucial element to enhance yields as well bio-chemical properties namely protein and oil content in groundnut. Buildup of insoluble phosphates and chemical fixation in soil reduces phosphorus consumption ability in plants. Phosphorus use efficiency (PUE) can be increased with higher levels of phosphorus rate. The study was framed to investigate the effect of phosphorus fertilization on yield, nutrient acquisition, use efficiency and bio-chemical compositions of groundnut. Methods: The experiment was conducted in summer seasons of 2016 and 2017, using split plot design with three varieties (‘JL-24’, ‘Gangapuri’, ‘TAG-24’) in main plot and four fertilization levels (0, 40, 60, 80kg P2O5 ha-1) in sub plots. Result: The study revealed that pod yield enhanced significantly by 15.4%, 27.3% and 39.9% with increase in fertilization rates from 40kg to 80kg ha-1 compare to unfertilized plots. Protein and oil content showed a positive response with phosphorus application. Agronomic efficiency, recovery efficiency and utilization efficiency were also increased with phosphorus rates, whereas, partial factor productivity, agro-physiological efficiency and physiological efficiency had decreasing trends. ‘Gangapuri’ gave higher pod yield (1.80t ha-1), protein (24.27%) and oil (45.41%) content than other selected varieties. Enhanced phosphorus rate also increases nutrient uptake in groundnut.

Greenhouse floriculture operations pose significant environmental risk due to extensive inputs of fertilizer, especially nitrogen and phosphorus (P). Recent evidence shows that the use efficiency for nitrogen or sulphur is markedly improved in subirrigated potted chrysanthemums (Chrysanthemum morifolium Ramat.) by supplying a moderate level of the nutrient during vegetative growth, and removing the entire nutrient suite at the onset of reproductive growth, without adverse effects on plant quality. Here, two split-plot experiments were conducted with subirrigated, potted, disbudded chrysanthemums grown in a peat:perlite mixture under greenhouse conditions (high- or low-ambient light) with inorganic orthophosphate (Pi) treatment (2.6 mmol L−1 Pi supplied during the vegetative and reproductive stages, and 2.6, 1.95, or 1.3 mmol L−1 Pi supplied during the vegetative stage only) as the main plot and cultivar (‘Olympia’ and ‘Covington’) as the subplot. Market quality plants with sufficient tissue P were produced even when Pi delivery was reduced by approximately 75% over the crop cycle, compared with industry standards. The primary mechanism for sustaining plant growth with decreasing Pi delivery was improved acquisition or uptake efficiency, although some changes in internal P-utilization efficiency were evident, including the remobilization of both organic P and Pi during inflorescence development. Differences in biomass yields, tissue P concentrations, content-based P-use efficiency (PUEC = mg shoot dry mass/mg shoot P content) with constant Pi acquisition, and uptake- versus remobilization-based P supply for inflorescence growth established that ‘Olympia’ has a greater P-utilization efficiency than ‘Covington’. This modified subirrigation practice could contribute significantly to low-input production of floricultural crops.

A field experiment was conducted to evaluate the effects of pre-sowing treatment of calcium chloride and phosphorus fertilization individually and combinely on the yield, oil content and physico-chemical properties of groundnut. This experiment consists of three pre-sowing treatments of calcium chloride solution (0%, 0.15%, 0.25%,0.50%) and four doses of phosphorus (0,30,45,60,75 kg/ha) with control. Pod yield of groundnut found 2.25 t/ha was maximum at 0.50% calcium chloride presowing treatment. The number of pods/plant (26.86) as well as, weight of 100 seeds (88.49) found significantly increased by applying 75 kg P2O5 / hectare when compared to the control. From the interaction of pre-sowing and fertilizer treatments, ie, 0.50% pre-sowing of calcium chloride (T3 ) with 75 kg P2O5 / hectare ( P4) produced significantly increased of pod yield (2.54 t / ha) and oil content (47.25%) of groundnut. Responses of pre-sowing and fertilization treatments on physico-chemical properties of groundnut oil such as refractive index, peroxide value, density remained unchanged throughout this experiment.

A study was conducted to determine the effects of nitrogen (N) and phosphorus (P) concentrations and P use efficiency from Minjingu phosphate rock (MPR), Minjingu mazao and Triple Super Phosphate (TSP) fertilizers under irrigated rice (Oryza sativa L.) production in Lekitatu village, Meru district, Arusha region, Tanzania. The initial soil pH in the two experimental sites was slightly alkaline while total N and available P was low and medium respectively. Randomized Complete Block Design (RCBD) with three replications was adopted and phosphorus was applied at the rates of 0, 20, 40 and 60 kg P ha-1 as MPR, Minjingu mazao and TSP. Nitrogen was applied uniformly at a rate of 60 kg N ha-1 as urea taking into account the 10% N contained in the Minjingu mazao fertilizer. Phosphorus application increased N and P contents in the rice plants and phosphorus use efficiency (PUE) with the increase of P levels from 0 to 60 kg P ha-1 for all P sources. The site 1 had more PUE than site 2 due to higher moisture content. These effects were due to increased availability and nutrients uptake by plants, particularly P. Based on the results, it is recommended that; Minjingu mazao at the rates of 40 to 60 kg P ha-1, MPR and TSP at a rate of 60 kg P ha-1, respectively have to be adopted for sustainable soil P use in rice production areas of Lekitatu village.

hree field experiments (2008 to 2011) were conducted to evaluate the ability of winter wheat (Triticum durum Desf. var. Carioca) to utilize and acquire soil phosphorus and nitrogen under different sources of phosphate fertilizers (Fosfactyl, Single super phosphate and Mono-ammonium-phosphate) and rates of applications (30, 60, 90 and 120 kg Pha-1) with a fixed level of nitrogen fertilization. Results revealed a significant effect of P rates on phosphorus use efficiency (PUE) and nitrogen use efficiency (NUE); however, P sources fertilizer had non-significant effect in all three cropping seasons. PUE and NUE decreased markedly with increasing P supply that did not result in an improvement of P and N uptake. Grain protein content was significantly influenced by phosphorus fertilization in 2008-09. The best values were obtained by Single super phosphate and P rate 60 kg ha-1.

Phosphorus (P) is one of the major constraints for crop growth and development, owing to low availability and least mobility in many tropical soil conditions. Categorization of existing germplasm under P deficient conditions is a prerequisite for the selection and development of P efficient genotypes in the mungbean. In the present investigation, 36 diverse genotypes were categorized for phosphorus use efficiency traits using four different techniques for identification of phosphorus use efficient mungbean genotypes. The studied genotypes were categorized for P efficiency based on efficiency, responsiveness, and stress tolerance score of genotypes under normal and low P conditions. The mean values of traits, root dry mass, root to shoot ratio, and P utilization efficiency are significantly higher under low P conditions indicating the high responsiveness of traits to P deficiency. The presence of significant interaction between genotypes and P treatment indicates the evaluated genotypes were significantly affected by P treatment for studied traits. The total P uptake showed significant and positive correlations with root dry mass, shoot dry mass, total dry mass,and P concentration under both P regimes. Out of the four techniques used for the categorization of genotypes for P efficiency, three techniques revealed that the genotype PUSA 1333, followed by Pusa Vishal, PUSA 1031, and Pusa Ratna is efficient. The categorization based on stress tolerance score is the finest way to study variation and for the selection of contrasting genotypes for P efficiency. The identified P efficient genotypes would be valuable resources for genetic enhancement of P use efficiency in mungbean breeding.
