White lupin (Lupinus albus) is a leguminous crop with elite adaptive ability in phosphorus-deficient soil and used as a model plant for studying phosphorus (P) use. However, the genetic basis of its adaptation to low P (LP) remains unclear. ATPase binding cassette (ABC) transports G subfamily play a crucial role in the transportation of biological molecules across the membrane. To date, identification of this subfamily has been analyzed in some plants, but no systematic analysis of these transporters in phosphorus acquisition is available for white lupin.

Phosphorus (P) -rich soils develop in phosphorite residing areas while P-deficient soils are ubiquitous in subtropical regions. Little has been reported that how metabolites participate in the seed development and the processes involved in their coping with contrasting-nutrient environments.

Phosphorus (P) deficiency is second to nitrogen (N) and its deficiency is widespread. Soil based site specific P recommendation for sustainable crop productivity mainly relies on status, and availability of phosphorus. Representative soil samples (250) from different agro-ecological regions of Eastern Dry Zone (EDZ) of Karnataka were analysed for P status and randomly collected samples were analysed for P fractions.

The present study was conducted to evaluate the effect of phosphorus deficiency stress on root traits of diverse rice genotypes. Roots of rice genotypes grown in root rhizotron having soil P (P2O5 ≤ 7.59kg/ha), with and without P supplementation were compared for difference in total root length, lateral branching, surface area and volume.

These symbiotic microorganisms have extensive mycelial network and can increase the transport of other mineral elements such as zinc and copper. VAM fungi can play an important role in enhancing P availability to plants in deficient soils and can save P-fertilizer by 25-30% (Somani et al., 1990).

Present study was undertaken to evolve an efficient and reliable measure for management of sheath blight of rice through application of judicious doses of plant nutrients. In this investigation, the effect of different doses i.e. control dose (naturally available in soil), deficient dose, recommended dose and excess dose of macronutrients (N, P &K) & micronutrients (S, Zn & Fe) were assessed on incubation period for first appearance of sheath blight, disease severity and on phenolic contents in inoculated rice plants.

Agriculture is going through a profound revolution worldwide due to increasing world demand for food, higher costs of energy and other inputs, environmental pollution problems, and instability of cropping systems. The importance of plant functioning can be realized from the facts that knowledge of mineral nutrition of plants has opened new vistas for fertilizer practices. The detection of deficiencies and toxicity of particular mineral nutrient element has enabled us to make adequate soil amendments and root nutrient absorption for better plant growth.

Geo-statistics is an important tools extensively used for analyzing the spatial variability, interpolating between point observations and ascertaining the interpolated values with specified error using a minimum number of observations. GPS based two hundred seventy two surface soil samples were collected randomly from agricultural area of Alirajpur district of Madhya Pradesh under AICRP on MSN project. Results recorded that the73.90, 26.10, 77.57, 64.71, 93.01 and 25.37 per cent soil samples were found to be deficient in N, P, K, S, Zn, and Fe respectively.

The field experiment was conducted during Kharif 2017 at Post Graduate Research Farm, College of Agriculture Kolhapur with the view to study the effect of integrated phosphorus management for yield, nutrient uptake of soybean grown on “P” deficient soil. The soil of experimental site was slightly alkaline in reaction, low in available nitrogen, low in available phosphorus and very high in available potassium.

Phosphorus (P), an essential macronutrient, is often limiting in soils and affects plant growth and development. In Arabidopsis thaliana, Low Phosphate Root1 (LPR1) and its close paralog LPR2 encode multicopper oxidases (MCOs).

Two pot experiment was conducted at Instructional Farm of Krishi Vigyan Kendra, Raigarh (C.G.) during Kharif season, 2015 for identification of yield limiting nutrients through crop response in Vertisol and Inceptisol of Raigarh district of Chhattisgarh with rice (MTU-1010) as test crop. The experiments were laid out in Completely Randomized Design with 11 treatments and 3 replications. Yield attributing characters viz. effective tillers, filled grains panicle-1 and grain and straw yields of rice in both soil types were significantly influenced by nutrient omission treatments.

Cluster bean (Cyamopsis tetragonoloba L.) is an important legume crop of India which can thrive well in adverse conditions. Despite of the fact that P is abundant in the soil it cannot be assessed by plants. Bacteria like rhizobium isolated from root nodules have potential to solublize the insoluble phosphorus. Thus, it plays a vital role in enhancing the phosphorus availability and overcoming phosphorus deficiency through its transformations into available form and thereby enhancing the agricultural productivity in a sustainable way.

Panax notoginseng is a medicinally important Chinese herb with a long history of cultivation and clinical application. The planting area is mainly distributed in Wenshan Prefecture, where the quality and safety of P. notoginseng have been threatened by high concentration of arsenic (As) from the soil.

A field experiment was carried out to evaluate the effect of sulphur and phosphorus application on yield and N, P and K contents of soybean grown on Vertisol. It was found that increasing application of sulphur and phosphorus, singly as well as in combination, significantly increased the grain yield and contents of N, P and K over control. The interaction of S x P exhibited a strong synergistic relationship in soybean nutrition grown on deficient soil.

Magnesium (Mg) is the structural component of chlorophyll and polysaccharides and also an activator of several enzymes. Magnesium plays an important role in photosynthesis. An attempt was made in the present investigation on utilizing this property for increasing rate of photosynthesis of maize plant and subsequently higher root exudations which enhance the microbial activities in soil. Green house experiments were conducted to evaluate the effect of MgO nano particles spray on maize plant (Zea mays L.) in three benchmark soils of India which are phosphorus (P) deficient.

Though one sixth of the global population resides in India, paradoxically, one third of about two billion people are suffering from vitamin and micronutrient deficiency in India due to heavy dependence on cereals grown in Zn- deficit soils. With the hypothesis that the residual Zn present in soil can also enhance the grain Zn content, a study was conducted with wheat variety ‘HD 2329’ to assess the grain concentrations of Zinc (Zn), Iron (Fe) and Phosphorus (P) grown on residual zinc in soils with divergent characteristics.

Positive responses to Zn addition on numerous crops have been documented. In this study, we field tested no Zn (0 kg ZnSO4.7 H2O/acre) and Zn treatment (25 kg ZnSO4.7 H2O/acre) in zinc deficient sites and their effect on grain yield of Pusa Basmati 1121. Surface soil samples (0-15cm) were collected from 16 sites from basmati rice grown soils in Gurdaspur district of Punjab. Findings of the study revealed that soils had variable available phosphorus and zinc status. The grain yield ranged from 20.8 to 29.8 q/ha in control with mean value of 25.
