(1) Phosphorus (P) is an essential plant nutrient, and P deficiency negatively affects plant growth and development. Furthermore, P is a finite and nonrenewable resource, and there is an urgent need to recover P from some of the important waste streams in society. Newly engineered calcareous materials (sol–gel coated cat litter (CATSAN®)) can bind P from wastewater in decentralized treatment systems and potentially enable P recycling into agricultural production by direct addition of the P saturated material. (2) The effects of the addition of two P-enriched calcareous materials as fertilizers for maize (Zea mays L.) growth were investigated in a mesocosm experiment. We compared fertilization with the P-enriched materials at rates of 6, 12, 25, 50, 100 kg P ha−1 yr−1 with fertilization with commercial NPK fertilizer. (3) The P fertilization by the P-enriched materials had a significant positive effect on plant height, biomass, maximum light-saturated photosynthetic rate, respiration rate, and total P content in biomass. However, plants fertilized by the commercial NPK fertilizer performed significantly better in the majority of measured parameters at identical fertilization rates. (4) The bioavailability of the P bound to the calcareous material was very low. However, the studied material has the potential to be used as part of a decentralized treatment solution to remove and subsequently recover and recycle P from wastewater.

Effects of mono-, diammonium, and superphosphate with added urea or ammonium nitrate on corn (Zea mays L.) growth were studied in the field in 1971 and 1972. At the rate of 100 kg P2O5/ha, none of the carriers affected emergence of seedlings in five Quebec soils. Leaf P content at silking time was of little benefit in predicting P status of the plants, or in differentiating among the carriers. Phosphorous applications gave significant corn yield increases, with carriers performing alike when averaged over all sites. However, some yield differences among carriers occurred on some soil types and seasons. These carrier differences were not consistent and remain to be clarified. The ammonium phosphates compared with the check generally hastened maturity but reduced potassium levels in leaf tissue of corn.

Maize is one of food commodity in Indonesia. Maize pioneer 21 is a kind of high-yielding maize variety in Indonesia. One of the way able to be conducted to improve growth of  maize plant is with fertilizing combination of nanosilica and NPK. This research aim to know the influence of fertilizing combination of nanosilica and NPK toward improving growth of maize plant and to know optimal concentration of combination nanosilica fertilizer and NPK in corn plants growth. Nanosilica is  fertilizer that contains micronutrients Si while the NPK fertilizer contains macro nutrients NPK. Research conducted with Completely Ramdomized Design (CRD) with 6 combination factor: P0 (control), P1 (100% nanosilica), P2 (75% nanosilica + 25% NPK), P3 (50% nanosilica + 50% NPK), P4 (25% nanosilica + 75% NPK) and P5 (100% NPK) each has 3 replications. Parameter perceived by hat is high of plants, high of leaf, amount of leaf, wet heavy of maize plants and dry heavy of maize plant. Data to be analysed with Analysis of variance (ANOVA) level of signification 95%, continued by Duncan Multiple Range Test (DMRT) level of signification 95%. The results showed that the combination of nanosilica fertilization and NPK significantly affected the wet weight and dry weight of the Maize P-21. The optimal combination for the growth of Maize P-21 is the treatment of P4 (25% nanosilica+ 75% NPK).  Key words: Zea mays L var. pioneer 21; combination; fertilizing; nanosilica; NPK

This study aims to determine the dose combinations of inorganic fertilizers and the fermentation of organic cow dung that respond well to corna. This research was conducted by August to November 2020, in the experimental garden of the Agriculture Faculty, Siliwangi University, Mugarsari Village, Tamansari District, Tasikmalaya City with a height of 360 meters above sea level (m asl). The study used a randomized block design (RBD) with 6 treatments and was repeated 4 times. Dose tested P0 = control (without being given fertilizer), P1 = Poration of cow dung 20 t / ha, P2 = NPK 300 kg / ha, P3 = NPK 250 kg / ha + cow dung poration 5 t / ha, P4 = NPK 200 kg / ha + poration of cow dung 10 t / ha and P5 = NPK 150 kg / ha + poration of cow dung 15 t / ha. The results showed that the application of NPK fertilizer and cow dung could be responded to by corns, with the results of statistical analysis that was significantly different on plant height at 18 DAS, weight of 100 seeds and shelled weight per hectare.

Field experiments were conducted in 1988 and 1989 to determine the most efficient phosphorus (P) placement for P absorption by maize (Zea mays L.) in early growth stages. The treatments consisted of four rates of applied P (0, 25, 50 and 100 kg P ha−1) mixed with 3, 6, 12 and 25% of the soil volume in the row. Shoots and roots were sampled at 3- to 4-leaf, 6-leaf, and 8- to 9-leaf stages. The roots inside and outside the zone of P fertilization were sampled separately. There was no evidence of root proliferation in the fertilized zones, even with the 100 kg P ha−1 rate mixed with 3% of the soil volume. There was a significant response of shoot dry matter, shoot P concentration, shoot P uptake, and root growth to applied P. Shoot P concentration and shoot P content increased as the volume of soil with which fertilizer P was mixed decreased. Mixing 100 kg P ha−1 with 3–6% of the soil volume resulted in the highest shoot P content in the early growth stages. There was no evidence that fertilizing a greater proportion of soil than the conventional band method will result in higher P uptake of maize in early growth in the soil studied. Because the soil in the study had a relatively low P adsorptive capacity, this conclusion is likely valid for a broad range of soils, which have a greater P adsorptive capacity. Key words: Phosphorus placement, maize, root growth, phosphorus absorption
