“…Gazola and collaborators [27] did not observe statistical differences between conventional and polymer-coated MAP in maize (Zea mays L.). Another study [28] reported higher yields of maize and common bean (Phaseolus vulgaris L.) under application of polymer-coated MAP compared with yields under conventional MAP.…”

In an effort to improve fertility, recover degraded areas and increase support for the capacity of livestock on pasture, new forms of fertilizer are being developed. Polymer-coated monoammonium phosphate (MAP) is an innovative source of phosphorus (P) for maintaining forage grass productivity. The aim this study was to evaluate the agronomic efficiency of P rates with the presence and absence of the polymer on the productivity, development and nutritional value of hybrid signalgrass (Urochloa spp.) cv. Mavuno. The field research was conducted on a dystrophic Ultisol. The experiment was arranged in a randomized complete block design with four replications and treatments applied in a factorial scheme (2 × 4) + 1. The treatments included two P sources (uncoated MAP and polymers-coated MAP) at four rates (20, 40, 80 and 160 kg ha−1 of P2O5), and the control received no P fertilization. The measured variables showed no differences between sources with or without polymer. The maximum production of accumulated shoot dry weight yield (SDWY) of the ‘Mavuno’ grass was 20.2 Mg ha−1 with the dose of 114 kg ha−1 of P2O5. The value of crude protein and in vitro dry matter digestibility showed a quadratic response with maximum production of 76.5% and 15.9% for the P2O5 rates of 37.2 and 91.1 kg ha−1, respectively, while the acid detergent insoluble fiber showed a linear increase up to the rate of 80 kg ha−1 of P2O5. No differences were observed in plant height, number of tillers, or the relative chlorophyll content between treatments.

“…The treatments, applied in the planting furrow, were arranged in an incomplete factorial (2 × 4) + 1, using two P sources (MAP: 11% N, 52% P 2 O 5 and Policote coated MAP: 10% N, 47% P 2 O 5 and 1.9% Mg), four P rates (40, 80, 120 and 160 g P 2 O 5 plant −1 ) and control (without P application). Policote is a water-soluble polymer additive distributed by Wirstchat [48]. A randomized block design with three replications was used.…”

Phosphorus (P) plays a crucial role in plant growth by aiding in the development of strong roots, promoting flower and fruit formation, and aiding in photosynthesis. Studies to improve P fertilizers efficiency in coffee orchards are necessary due to the need for better efficiency and the lack of information on enhanced efficiency P fertilizers. This study aimed to investigate the effect of MAP coated with anionic polymers (Policote) on coffee orchard development. A coffee trial was carried out in a randomized block design with three replications. The treatments, applied at coffee planting, were arranged in an incomplete factorial (2 × 4) + 1, using two P sources (MAP and Policote coated MAP), four P rates (40, 80, 120, and 160 g P 2 O 5 plant −1 ) and control (without application of P fertilizer). Plant height was evaluated in the 2016/2017, 2017/2018, and 2018/2019 seasons, while coffee bean maturation, yield, and agronomic P efficiency use were evaluated in the last two seasons. P fertilization did not affect coffee bean maturation and increased coffee yield in 31-month-old plants when differences among P sources and rates were observed. Using Policote-coated P fertilizer resulted in higher yields at the same P rate, as well as similar yields at a lower P rate, compared to conventional fertilizer. Policote-coated P fertilizer can be used as an enhanced efficiency fertilizer and is an efficient way to deliver required P to plants. The target for reducing farm investment, increasing agricultural profits, preserving phosphatic rock reserves, and avoiding the overuse of phosphate fertilizer could be realized through the rational use of enhanced efficiency fertilizers.

“…The great increase in chemical fertilizer inputs in the last 20 years has led to a great increase in vegetable yield [3,4]. However, the increase in the cost of chemical fertilizers and its incorrect application caused a decrease in the yield and quality of vegetables as a result of the deterioration of the balance of the soil environment [5][6][7].…”

In this study, application of different bacterial strains obtained from different ecosystems of Turkey with increasing doses of chemical fertilizers (NPK) was repeated for two years in field conditions in order to determine the effects on plant growth, yield and quality in cauliflower. Six PGPR strains (SA7, SB39, YÖ19, YÖ15, YÖ,41, SK72 107cfu/ml) from the trial subjects and a control group were added. Fertilizer applications were determined over the recommended dose; The rates of 0% NPK0, 50% NPK, 100% NPK and 200% NPK were applied. In the study, crown length, crown diameter, crown weight, leaf length, leaf diameter and marketable yield values were measured in sample plants selected on the basis of plots. Marketable yield values for 2021; NPK0 dose YÖ41, YÖ15 (2.55 ton ha -1 ), 1/4NPK dose YÖ41 (2.98 ton ha -1 ), 1/2NPK dose YÖ41, YÖ15 (4.57 ton ha -1 ), NPK dose YÖ41 (4.74 ton ha -1 ), 2NPK dose It was determined as YÖ41 (4.69 ton ha -1 ). Marketable yield values for 2022; NPK0 dose YÖ41 (2.16 ton ha -1 ), 1/4NPK dose SA7 (3.26 ton ha -1 ), 1/2NPK dose YÖ41 (4.73 ton ha -1 ), NPK dose YÖ41 (5.03 ton ha -1 ), 2NPK dose YÖ41 (5.11 ton ha -1 ) was determined. As a result of the research, it was determined that the effects of bacterial applications on the growth of the cauliflower plant are important. When the effects of applied bacterial strains on plant growth were examined, YÖ41, YÖ15 bacterial strains came to the fore, while other bacterial strains had a positive effect on all parameters.
