“…Similarly, phosphatic fertilizer use efficiency increased from 24% to 34% when applied with the Si fertilizer due to reduced phosphorus retention capacity in soil with increased water-soluble phosphors levels (Singh et al 2005). Many studies have reported the positive effects of Si on crop yield (Alovisi et al 2014;Emam et al 2014;Gholami and Falah 2013;Kim et al 2012). Epstein (2001) reported that Si promotes the plant growth whereas Haldar and Mandal (1981) observed that application of phosphorus in rice significantly increased the plant dry biomass accumulation.…”

A pot experiment was conducted to investigate the effects of silicon and phosphatic fertilization on rice yield and soil fertility. Three levels of silicon (Si) fertilization i.e., SiO 2 : 45, 135, and 225 kg hm −2 and the two phosphatic fertilizer i.e., P 2 O 5 : 15 and 45 kg hm −2 for each of calcium superphosphate (CS) and combined calcium-magnesium phosphate (FCMP) (used as phosphatic fertilizer source) were applied to a rice cultivar "II you 128". The treatment applied with P 2 O 5 45 kg hm −2 CS and without Si fertilization was taken as control (CK). The grain yield was improved with increasing Si fertilizer application, whereas phosphatic fertilization also affected the grain yield significantly. The FCMP showed better grain yield than CS whereas the interactive effect of Si and CS fertilizer showed higher Si contents in stem sheath, available Si in soil, water-soluble Si contents in soil and soil active Si contents but lower available phosphorus in soil and soil phosphatase activity than the Si and FCMP fertilizer interaction. Moreover, the grain yield showed significant positive correlation with aboveground dry weight (r = 0.9951) and harvest index (r = 0.8364). Overall, Si fertilization improved rice yield, whereas FCMP was found better than CS regarding grain yield improvement. The grain yield increased with increasing Si fertilizer application whereas the FCMP was found better than CS regarding grain yield improvement of rice. The supplementation of Si and phosphatic fertilizers substantially improved available Si and P contents of soil.

“…While the critical levels of soil available Si extracted by 0.5 M acetic acid for rice plants ranged from 44 to 116 ppm, according to [33]. Considering these levels into account, the applied P in the studied soil till 13 mg kg −1 considered adequate, while applying Si to the studied soil till 400 mg kg −1 considered high but not within the toxic range according to the previous studies of [13].…”

“…Ma and Takahashi [12] studied the effect of Si on the growth and P uptake of rice and found that, addition of Si raised the optimum P level for rice and enhanced plant growth and yield. Alovisi et al [13] studied the Si-P interactions in some soils cultivated with bean plants in Brazil and found that, application of silicate could increase P availability to plants, based on the fact that the silicate anion occupies the adsorption sites of the phosphate anion, which reflect on enhancing plant growth and yield and increasing the content of its different parts with P. Greger et al [14] reported that Si increased the availability of P; it might be due to that Si modifies uptake and acquisition of P for plants. Silicon is known to reduce the soil sorption of P, especially at low pH, thus, increases the plant-available portion of P in the soil [15].…”

A pot experiment was conducted in clay soil collected from Agricultural Research Center farm, Giza governorate, Egypt. Wheat grains (Triticum aestivum L., Giza 168) were cultivated to study the effect of silicate and phosphate ions as well as their interactions on the growth and nutritional status of the growing plants, beside their availability in the studied soil. Silicon (Si) in the form of sodium meta-silicate penta-hydrate (Na2SiO3.5H2O) was added at a rate of 0, 200, 300 and 400 mg Si kg-1 soil, and phosphorus (P) in the form of calcium super phosphate was given at a rate of 0, 3.5, 7.0, 10.0 and 13.0 mg P kg-1 soil to represent 0, 25, 50, 75 and 100% of the recommended rate of P fertilization by the Egyptian Ministry of Agriculture for wheat cultivation. Also, the experiment included combinations between all these concentrations of Si and P. Obtained results showed that Si and P availability increased in the studied soil with increasing either Si or P concentrations added. This means that P availability in soil as an essential element for plant growth can be improved by addition of Si. Also, Si increased in plant with increasing applied Si concentrations. Interaction between Si and P generally increased all parameters of plant growth; such responses were significant for fresh and dry weights of wheat plants at booting stage. It could be recommended that selecting good P fertilization design, including time and rate of addition, goes along with values of available Si in the soil.

“…Phosphorous content increased linearly with P 2 O 5 doses, with a maximum concentration of 4.9 g P kg -1 in the application of 200 mg P 2 O 5 dm -3 , indicating that the greater availability of P in soil reflects in the greater absorption and incorporation of this nutrient in the biomass, with a consequent increase in of lima bean production. Linear responses in the accumulation of P with phosphate fertilization are widely reported in the literature for different cultivars of the genus Phaseolus (A. M. T. Alovisi, Furtini Neto, Carneiro, Curi, & A. A. Alovisi, 2014;Santos et al, 2011;Silva et al, 2014).…”

Lima bean stands out in the agricultural sector as a source of income for small and medium farmers, being an important protein source for the population. However, there few studies related to the adequate management of fertilization that subsidize the maximization of crop production. In this context, the objective of this research was to evaluate the effect of macronutrient doses on the yield components and nutritional status of lima bean. The treatments were chosed based on the statistical arrangement of the Baconian method. Six nutrients (nitrogen, phosphorus, potassium, calcium, magnesium and sulfur) were applied in three different doses along with two additional treatments, one with reference doses and the other with no addition of nutrients, totaling 20 treatments that were arranged in a completely randomized design with four replications. The pod length, pod number per plant, pod weight, number of grains per pod, number of grains per plant, grain weight per plant and macronutrient leaf contents were evaluated. The addition of macronutrients leads to increases in yield components and nutritional status of lima bean s when cultivated in Entisol Quartzipsamment. The doses of macronutrients that promote higher productive yield and adequately supply the nutritional needs of lima beans are: 25 mg N dm-3; 157 mg P2O5 dm-3; 90 mg K2O dm-3; 1.27 cmolc Ca dm-3; 0.50 cmolc Mg dm-3 and 30 mg S dm-3.
