“…The soil on which the experiment was conducted had varied levels of soil properties that define soil fertility and depicted the nutrient gradient occasioned by differences in slope position (Liu et al, 2020). The high contents of soil nutrients contained in the poultry manure used for this study is further indicative of the fact that poultry manure is a potent means of boosting the fertility inherently poor soils.…”

A study was conducted to determine the effects of slope position and fertilizer type on soil properties and growth of maize (Zea mays) on Coastal Plain Sands of Akwa Ibom State, Nigeria. Results obtained showed that soils of lower slope (LS) had the highest contents of clay and silt compared with those of upper slope (US) position. Bulk density of the upper slope soil and that of the middle slope (MS) soils were significantly higher (P≤0.05) than that of LS soil and subsequently, total porosity and saturated hydraulic conductivity (Ksat) increased downslope. Bulk density of soils that received poultry manure (PM) and NPK+PM were significantly reduced compared to those of NPK and control while total porosity and Ksat of soils that received PM and NPK+PM were significantly higher (P≤0.05) than those of NPK and control. Soils of LS had highest pH, organic carbon, total nitrogen, available phosphorus, ECEC compared to those of MS and US. The application of poultry manure yielded increase in soil pH, soil organic carbon, total nitrogen, available phosphorus and ECEC when compared to soils of NPK and control. Growth of maize obtained with LS were consistently higher than those of the MS and US soils. Soils of LS that received NPK and NPK+PM had consistently similar maize growth, higher than other combinations of slope position and fertilizer type. The complementary application of poultry manure and NPK 15:15:15 can be the best option for increasing the fertility of soils with varying slope positions on Coastal Plain Sands.

“…As plant density increases, the interaction between roots of the neighboring plants has a greater influence on grain formation. Any impact on dry matter distribution and nutrient absorption significantly affects the change in yield (Yang et al 2020). Studies have positively correlated root biomass with green leaf area (Ogawa et al 2005).…”

To better understand the accumulation and transport of substances under different planting densities, the adaptation of maize root and leaf in response to increasing planting densities was investigated. In this two-year filed study, three maize varieties, Fumin108 (FM), Xianyu335 (XY) and Dika159 (DK), were sown under three different planting densities: 15,000 (D1), 60,000 (D2) and 90,000 plants ha-1 (D3) during 2018 and 2019. Increase in planting density gradually increased leaf area index along with reduced leaf area and net photosynthetic rate of individual leaves. In the 0–20 cm soil layer, the average root dry matter decreased by 55.88 and 80.92%, and the average root number decreased by 31.18 and 38.71% under D2 and D3, respectively, compared with D1. With increase in planting density, yield and dry matter per plant of maize gradually decreased while yield and dry matter per ha was increased with increase in D1-D2 density and then flattened in D2-D3 density. Compared with D1, two-year average yield per plant was decreased by 34.10 and 51.87% under D2 and D3, respectively. The difference in the number of roots of XY, FM and DK were not significant, so change in variety did not alleviate the decrease in the number of roots. At higher planting densities (above D2), the increase in density did not increase per ha grain yield. In conclusion, the suitable plant density was about 60,000 plants ha-1 to harvest more yield of spring maize while density higher than that reduced leaf area and photosynthesis per plant. Moreover, leaf area, root number and net photosynthesis per plant was higher in lower planting density coupled with overall less yield on ha basis and thus seemed wastage of soil nutrients and light resources. © 2021 Friends Science Publishers

“…Compared to conventional urea, nBPT protects the fertilizer from the action of urease during hydrolysis after its application to the soil, which provides the delay of the transformation of amide nitrogen into ammonia for 10-15 days [9,7]. This contributes to the losses reduction of nitrogen in form of ammonia up to 60% compared to losses from conventional urea, even compared to the incorporation it into the soil [6,10].…”

In the article are presented the investigation results, which shows the effectiveness of urea with urease inhibitor – nBPT in potato growing agroecosystems. The advantages of the new fertilizer are the yield increase, and quality improvement. Urea with nBPT lead to formation bigger tuber size what is one of the most important characteristic for marketable potato. Fertilizer was tested in experimental fields and in real farm conditions.
