The tendency of phosphorus (P) to undergo adsorption and precipitation reactions in soil makes it one of the most immobile of the essential plant nutrients. As a result, the concentration of available P in soil solution is usually very low even though the total P content of soils is generally high. Consequently, P is second only to N in limiting crop productivity. In areas of the world such as the North America and Europe in which P fertilizers are applied liberally to agricultural fields, the loss of this nutrient through its transport in particulate and soluble forms from agricultural fields to lakes and rivers is of concern due to accelerated eutrophication. The need to provide crops with adequate P combined with the desire to minimize the adverse effect of P on the environment will 1101 ORDER REPRINTS require strategies to reduce P inputs and to maximize the efficiency of P uptake mechanisms in plants. Recent advances in molecular biology offer opportunities to manipulate plants to increase uptake efficiencies of P. Integration of arbuscular mycorrhizal fungi into cropping systems provides an alternative means of maintaining yields while reducing P inputs. To realize the potential of these new technologies, however, a thorough understanding of both soil and plant factors involved in P uptake, and the effects of cultural practices on arbuscular mycorrhizal associations are needed. A review of the literature was undertaken to summarize the relevant state of knowledge on P uptake processes in plants and the mechanisms by which P uptake efficiencies could be enhanced, with particular emphasis on arbuscular mycorrhizal fungi. 1102 MIYASAKA AND HABTE Downloaded by [University of Colorado at Boulder Libraries] at 20:55 25 December 2014 ORDER REPRINTS Water QualityAccelerated eutrophication of lakes and streams in the United States has been attributed primarily to non-point source pollution of P from agriculture (Daniel et al., 1998;Mathews et al., 1998). From cultivated lands, a major proportion of P is transported as particulate P associated with soil particles or organic matter during erosion events (Sharpley et al., 1992). From grasslands, forests, or non-erosive soils, P in runoff is predominantly soluble P (Daniel et al., 1998;Sharpley et al., 1992).Plants can be a critical component in reducing P loss from agricultural soils, by providing plant cover to prevent erosion, or by taking up P i from soil solutions and reducing its concentration. Thus, it is important to understand the processes by which plants take up, regulate, and transport P within the plant, and the various plant mechanisms and mycorrhizal symbioses that can increase P uptake efficiency.

Sugarcane productivity is stagnating in India. Demand for sugarcane is increasing. Scope for extending sugarcane area in the country is limited. Under these circumstances, emphasis must be on increasing sugarcane productivity. Technologies such as situation-specific cultivars, newer planting techniques, heat therapy or meristem culture derived quality seed material, site-specific and cultivar-specific nutrient management, drip irrigation, fertigation, integrated weed management, abiotic and biotic stress management, etc. have the potential to increase yields substantially. This paper reviews some of the recent developments in these areas and suggests how these technologies can be applied at field level to enhance productivity.

“…It is crucial for many metabolic processes, such as photosynthesis, respiration, the synthesis of nucleic acids, and energy generation (Balemi and Negisho, 2012). In sugarcane, P is essential for tillering and for the formation of a strong and vigorous root system (Sundara, 1994). The availability of P is a determining factor in the growth of the plant.…”

“…Phosphorus use efficiency can be divided into P absorption efficiency (PAE), which refers to the capacity of the plant to absorb P from the soil, and P utilization efficiency (PUE), which refers to the capacity of the plant to produce biomass or grain using the P absorbed (Wang et al, 2010). In sugarcane, P‐efficient cultivars, in general, produce a higher cane yield per unit of P absorbed (Sundara, 1994).…”

“…To date, few scientific studies have described the behavior of sugarcane genotypes in response to P availability in the soil and the characteristics associated with nutrient use efficiency. Sundara (1994) demonstrated that a lower tissue P value and higher dry matter production per unit P may be useful criteria to select P‐efficient cultivars under low‐P conditions, even though only efficiency indices based on cane and sugar yields were used for classifying cultivars.…”

Genetic Variation Affecting Agronomic Traits in Sugarcane in Response to High and Low Phosphorus Availability

et al. 2014

Low P availability in the soils of tropical regions is one of the main factors limiting agricultural production. Improving the efficiency of P use in plants is recognized as a less onerous and more sustainable method of maintaining satisfactory production in P-deficient soil. The aims of this study were to assess the existence of genetic variability for P use efficiency in sugarcane (Saccharum spp.) and to identify useful variables for the selection of efficient and responsive genotypes under low-and high-P conditions. The experiment was conducted in a greenhouse with 23 genotypes and two rates of P (40 and 240 kg ha -1 ) for 8 mo. We derived variables related to P absorption, accumulation, and utilization efficiency (PUE). Genotypes with similar productivities under high-P conditions varied widely in P-deficient soil. By measuring the production of dry aboveground mass, efficient genotypes under low-P conditions could be identified and classified regarding their efficiency and responsiveness to P. It was possible to classify the genotypes according to their P absorption efficiency (PAE) using the recovery rate of P and the root efficiency ratio. Regarding P accumulation, there was greater accumulation in the roots than in the stalks or leaves under low P. Under optimal P conditions, PUE measurements in the stalks and in the aboveground parts of the plant could be used to effectively select genotypes with superior nutrient use. Under low-P conditions, the PAE was more important in genotype selection.
