“…There were also no significant effects due to P rate or timing. Maier et al (2002a) reported a significant increase in stem number per plant with P fertilization in a greenhouse study, but no effects in a second greenhouse study or two field experiments. Jenkins and Ali (2000) found that P application had no effect on stem numbers in a 3-year field study.…”

“…Increases in tuber set with P application have been found by Freeman et al (1998), Jenkins andAli (2000), Maier et al (2002a), and Sanderson et al (2003). Tuber number and tuber size frequently have an inverse relationship (Knowles and Knowles 2006), but increases in tuber number with P fertilization have been accompanied by both increases and decreases in tuber size (Freeman et al 1998;Jenkins and Ali 2000).…”

A 3 year field study on a loamy sand soil with medium to high soil test phosphorus (P) concentrations (25 to 33 mg kg −1 Bray P1) was conducted to evaluate the effect of P fertilizer rate, source, and timing, and starter nitrogen (N) rate on potato (Solanum tuberosum L. cv. Russet Burbank) yield, tuber size, tuber set, petiole P concentration, and P uptake and distribution within the plant. Nine fertilizer treatments compared banded P rates of 0, 37, 42, and 74 kg P ha −1 , the P sources monoammonium phosphate (MAP) and diammonium phosphate (DAP), P banded at planting vs. split applications at planting and emergence, and starter N rates of 38 and 66 kg N ha −1 . Phosphorus fertilizer application increased total tuber yield and yield of undersized tubers (tubers less than 85 g), but decreased the proportion of large-sized tubers (greater than 285 g). Due to the increases in small, unmarketable tubers, P fertilizer application did not have a significant effect on marketable tuber yield (tubers greater than 85 g). The total number of tubers per plant and the number of undersized tubers were also higher, and the number of large tubers was lower, when P was applied compared with the zero P control. Both the number and yield of undersized tubers increased as P application rate increased. Petiole P concentrations were generally consistent with the rate of P applied, but they varied by year in magnitude and their pattern through the season. Petiole P was positively correlated with the number of tubers per plant, but only correlated for 1 year with differences in total yield. Phosphorus application increased total P uptake due primarily to an increase in tuber P concentration.Increases in total uptake and tuber P increased as P application rate increased, but differences in uptake were small relative to the amounts of P applied. Phosphorus source and timing and starter N rate did not consistently affect tuber yield, number, or size, petiole or tuber P concentration, and P uptake. The results of this study indicate that P nutrition can play an important role in regulating tuber set.Resumen Un estudio de campo en suelo arcillo-arenoso, con concentraciones mediana a alta de fósforo (P) (25 a 33 mg kg −1 Bray P1) se realizó durante tres años para evaluar el efecto de dosis de fertilizante, fuentes de P, control del tiempo y dosis inicial de nitrógeno (N) con papa (Solanum tuberosun L. cv. Russet Burbank) sobre el rendimiento, tamaño del tubérculo, número de tubérculos por planta, concentración de P en el pecíolo y absorción de P y su distribución dentro de la planta. Nueve tratamientos con fertilizantes compararon el P aplicado en bandas a las dosis de 0, 37, 42 y 74 kg P ha −1 , las fuentes de fosfato mono amónico (MAP) y fosfato di amónico (DAP), el P aplicado a la siembra con aplicaciones divididas a la siembra y a la emergencia y dosis de inicio de N de 38 y 66 kg N ha −1 .

“…An ample amount of P is therefore essential for optimizing the tuber yield, nutritional quality, and resistance of potato to some diseases also. Other studies have also demonstrated a significant increase in yield, number of tubers, and tuber size distribution due to fertilizer P application (Jenkins and Ali 1999;Maier et al 2002;Sanderson et al 2003). Even though an inverse relationship between tuber number and tuber size is reported (Knowles and Knowles 2006), an increase in tuber number with P fertilization has shown both an increase and decrease in tuber size (Freeman et al 1998;Jenkins and Ali 1999).…”

Phosphate Solubilizing Microorganisms

Vegetables are one of the important food components of dietary systems in many countries including Asian regions. It provides some of the essential nutrients such as carbohydrates, proteins, and fats and therefore plays a critical role in the human health. Vegetables while growing in soil require significant amounts of phosphorus for better biological growth and optimum yields. The soluble and available forms of phosphorous in soil are, however, limited and not accessible for uptake by vegetable crops. To this end, apart from chemical phosphatic fertilizers, one strategy to provide phosphorus to vegetable crops is the use of phosphate-solubilizing microorganisms, which are ubiquitous and both inexpensive and safe to the environment. Phosphate-solubilizing microorganisms secrete organic acid which in turn solubilizes the complex forms of phosphorus and makes it available to vegetable plants, besides exhibiting other growth-promoting activities. Here, the impact of phosphate-solubilizing microorganisms onto the growth and yield of vegetables is discussed and considered. This approach of using PS microorganisms in vegetable cultivation is likely to help in reducing, if not completely eliminating, the use of synthetic fertilizers in vegetable production across different regions of the world.

“…At low pH, Cd partitions to the solution phase (low K d ) and despite increased competition of H þ ions for Cd uptake by plant roots [87], plant Cd uptake increases due to the 2-to 4-fold increase in solution Cd concentrations for each unit decline in soil pH [88]. It should be noted however, that plant Cd uptake can sometimes be increased by liming of soils [89][90][91], and hypotheses have been developed to explain this phenomenon -increased Ca competition with Cd for soil sorption surfaces, or induced micronutrient deficiencies increasing Cd uptake.…”
